Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Amazon Elastic Container Service (Amazon ECS) is a highly scalable, fast, container management service. It makes it easy to run, stop, and manage Docker containers. You can host your cluster on a serverless infrastructure that's managed by Amazon ECS by launching your services or tasks on Fargate. For more control, you can host your tasks on a cluster of Amazon Elastic Compute Cloud (Amazon EC2) or External (on-premises) instances that you manage.

Amazon ECS makes it easy to launch and stop container-based applications with simple API calls. This makes it easy to get the state of your cluster from a centralized service, and gives you access to many familiar Amazon EC2 features.

You can use Amazon ECS to schedule the placement of containers across your cluster based on your resource needs, isolation policies, and availability requirements. With Amazon ECS, you don't need to operate your own cluster management and configuration management systems. You also don't need to worry about scaling your management infrastructure.

Sending a Request Using ECS

var ecs = new AWS.ECS();
ecs.createCapacityProvider(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the ECS object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var ecs = new AWS.ECS({apiVersion: '2014-11-13'});

You can also set the API version globally in AWS.config.apiVersions using the ecs service identifier:

AWS.config.apiVersions = {
  ecs: '2014-11-13',
  // other service API versions
};

var ecs = new AWS.ECS();

Version:

  • 2014-11-13

Waiter Resource States

This service supports a list of resource states that can be polled using the waitFor() method. The resource states are:

tasksRunning, tasksStopped, servicesStable, servicesInactive

Method Details

createCapacityProvider(params = {}, callback) ⇒ AWS.Request

Creates a new capacity provider. Capacity providers are associated with an Amazon ECS cluster and are used in capacity provider strategies to facilitate cluster auto scaling.

Only capacity providers that use an Auto Scaling group can be created. Amazon ECS tasks on Fargate use the FARGATE and FARGATE_SPOT capacity providers. These providers are available to all accounts in the Amazon Web Services Regions that Fargate supports.

Service Reference:

Examples:

Calling the createCapacityProvider operation

var params = {
  autoScalingGroupProvider: { /* required */
    autoScalingGroupArn: 'STRING_VALUE', /* required */
    managedDraining: ENABLED | DISABLED,
    managedScaling: {
      instanceWarmupPeriod: 'NUMBER_VALUE',
      maximumScalingStepSize: 'NUMBER_VALUE',
      minimumScalingStepSize: 'NUMBER_VALUE',
      status: ENABLED | DISABLED,
      targetCapacity: 'NUMBER_VALUE'
    },
    managedTerminationProtection: ENABLED | DISABLED
  },
  name: 'STRING_VALUE', /* required */
  tags: [
    {
      key: 'STRING_VALUE',
      value: 'STRING_VALUE'
    },
    /* more items */
  ]
};
ecs.createCapacityProvider(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • name — (String)

      The name of the capacity provider. Up to 255 characters are allowed. They include letters (both upper and lowercase letters), numbers, underscores (_), and hyphens (-). The name can't be prefixed with "aws", "ecs", or "fargate".

    • autoScalingGroupProvider — (map)

      The details of the Auto Scaling group for the capacity provider.

      • autoScalingGroupArnrequired — (String)

        The Amazon Resource Name (ARN) that identifies the Auto Scaling group, or the Auto Scaling group name.

      • managedScaling — (map)

        The managed scaling settings for the Auto Scaling group capacity provider.

        • status — (String)

          Determines whether to use managed scaling for the capacity provider.

          Possible values include:
          • "ENABLED"
          • "DISABLED"
        • targetCapacity — (Integer)

          The target capacity utilization as a percentage for the capacity provider. The specified value must be greater than 0 and less than or equal to 100. For example, if you want the capacity provider to maintain 10% spare capacity, then that means the utilization is 90%, so use a targetCapacity of 90. The default value of 100 percent results in the Amazon EC2 instances in your Auto Scaling group being completely used.

        • minimumScalingStepSize — (Integer)

          The minimum number of Amazon EC2 instances that Amazon ECS will scale out at one time. The scale in process is not affected by this parameter If this parameter is omitted, the default value of 1 is used.

          When additional capacity is required, Amazon ECS will scale up the minimum scaling step size even if the actual demand is less than the minimum scaling step size.

          If you use a capacity provider with an Auto Scaling group configured with more than one Amazon EC2 instance type or Availability Zone, Amazon ECS will scale up by the exact minimum scaling step size value and will ignore both the maximum scaling step size as well as the capacity demand.

        • maximumScalingStepSize — (Integer)

          The maximum number of Amazon EC2 instances that Amazon ECS will scale out at one time. If this parameter is omitted, the default value of 10000 is used.

        • instanceWarmupPeriod — (Integer)

          The period of time, in seconds, after a newly launched Amazon EC2 instance can contribute to CloudWatch metrics for Auto Scaling group. If this parameter is omitted, the default value of 300 seconds is used.

      • managedTerminationProtection — (String)

        The managed termination protection setting to use for the Auto Scaling group capacity provider. This determines whether the Auto Scaling group has managed termination protection. The default is off.

        When using managed termination protection, managed scaling must also be used otherwise managed termination protection doesn't work.

        When managed termination protection is on, Amazon ECS prevents the Amazon EC2 instances in an Auto Scaling group that contain tasks from being terminated during a scale-in action. The Auto Scaling group and each instance in the Auto Scaling group must have instance protection from scale-in actions on as well. For more information, see Instance Protection in the Auto Scaling User Guide.

        When managed termination protection is off, your Amazon EC2 instances aren't protected from termination when the Auto Scaling group scales in.

        Possible values include:
        • "ENABLED"
        • "DISABLED"
      • managedDraining — (String)

        The managed draining option for the Auto Scaling group capacity provider. When you enable this, Amazon ECS manages and gracefully drains the EC2 container instances that are in the Auto Scaling group capacity provider.

        Possible values include:
        • "ENABLED"
        • "DISABLED"
    • tags — (Array<map>)

      The metadata that you apply to the capacity provider to categorize and organize them more conveniently. Each tag consists of a key and an optional value. You define both of them.

      The following basic restrictions apply to tags:

      • Maximum number of tags per resource - 50

      • For each resource, each tag key must be unique, and each tag key can have only one value.

      • Maximum key length - 128 Unicode characters in UTF-8

      • Maximum value length - 256 Unicode characters in UTF-8

      • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

      • Tag keys and values are case-sensitive.

      • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

      • key — (String)

        One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

      • value — (String)

        The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

createCluster(params = {}, callback) ⇒ AWS.Request

Creates a new Amazon ECS cluster. By default, your account receives a default cluster when you launch your first container instance. However, you can create your own cluster with a unique name.

Note: When you call the CreateCluster API operation, Amazon ECS attempts to create the Amazon ECS service-linked role for your account. This is so that it can manage required resources in other Amazon Web Services services on your behalf. However, if the user that makes the call doesn't have permissions to create the service-linked role, it isn't created. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

      The metadata that you apply to the cluster to help you categorize and organize them. Each tag consists of a key and an optional value. You define both.

      The following basic restrictions apply to tags:

      • Maximum number of tags per resource - 50

      • For each resource, each tag key must be unique, and each tag key can have only one value.

      • Maximum key length - 128 Unicode characters in UTF-8

      • Maximum value length - 256 Unicode characters in UTF-8

      • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

      • Tag keys and values are case-sensitive.

      • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

      • key — (String)

        One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

      • value — (String)

        The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

    • settings — (Array<map>)

      The setting to use when creating a cluster. This parameter is used to turn on CloudWatch Container Insights for a cluster. If this value is specified, it overrides the containerInsights value set with PutAccountSetting or PutAccountSettingDefault.

      • name — (String)

        The name of the cluster setting. The value is containerInsights .

        Possible values include:
        • "containerInsights"
      • value — (String)

        The value to set for the cluster setting. The supported values are enabled and disabled.

        If you set name to containerInsights and value to enabled, CloudWatch Container Insights will be on for the cluster, otherwise it will be off unless the containerInsights account setting is turned on. If a cluster value is specified, it will override the containerInsights value set with PutAccountSetting or PutAccountSettingDefault.

    • configuration — (map)

      The execute command configuration for the cluster.

      • executeCommandConfiguration — (map)

        The details of the execute command configuration.

        • kmsKeyId — (String)

          Specify an Key Management Service key ID to encrypt the data between the local client and the container.

        • logging — (String)

          The log setting to use for redirecting logs for your execute command results. The following log settings are available.

          • NONE: The execute command session is not logged.

          • DEFAULT: The awslogs configuration in the task definition is used. If no logging parameter is specified, it defaults to this value. If no awslogs log driver is configured in the task definition, the output won't be logged.

          • OVERRIDE: Specify the logging details as a part of logConfiguration. If the OVERRIDE logging option is specified, the logConfiguration is required.

          Possible values include:
          • "NONE"
          • "DEFAULT"
          • "OVERRIDE"
        • logConfiguration — (map)

          The log configuration for the results of the execute command actions. The logs can be sent to CloudWatch Logs or an Amazon S3 bucket. When logging=OVERRIDE is specified, a logConfiguration must be provided.

          • cloudWatchLogGroupName — (String)

            The name of the CloudWatch log group to send logs to.

            Note: The CloudWatch log group must already be created.
          • cloudWatchEncryptionEnabled — (Boolean)

            Determines whether to use encryption on the CloudWatch logs. If not specified, encryption will be off.

          • s3BucketName — (String)

            The name of the S3 bucket to send logs to.

            Note: The S3 bucket must already be created.
          • s3EncryptionEnabled — (Boolean)

            Determines whether to use encryption on the S3 logs. If not specified, encryption is not used.

          • s3KeyPrefix — (String)

            An optional folder in the S3 bucket to place logs in.

      • managedStorageConfiguration — (map)

        The details of the managed storage configuration.

          Specify a Key Management Service key ID to encrypt the managed storage.

        • fargateEphemeralStorageKmsKeyId — (String)

          Specify the Key Management Service key ID for the Fargate ephemeral storage.

    • capacityProviders — (Array<String>)

      The short name of one or more capacity providers to associate with the cluster. A capacity provider must be associated with a cluster before it can be included as part of the default capacity provider strategy of the cluster or used in a capacity provider strategy when calling the CreateService or RunTask actions.

      If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must be created but not associated with another cluster. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.

      To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.

      The PutCapacityProvider API operation is used to update the list of available capacity providers for a cluster after the cluster is created.

    • defaultCapacityProviderStrategy — (Array<map>)

      The capacity provider strategy to set as the default for the cluster. After a default capacity provider strategy is set for a cluster, when you call the CreateService or RunTask APIs with no capacity provider strategy or launch type specified, the default capacity provider strategy for the cluster is used.

      If a default capacity provider strategy isn't defined for a cluster when it was created, it can be defined later with the PutClusterCapacityProviders API operation.

      • capacityProviderrequired — (String)

        The short name of the capacity provider.

      • weight — (Integer)

        The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

        If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

        An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

      • base — (Integer)

        The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

    • serviceConnectDefaults — (map)

      Use this parameter to set a default Service Connect namespace. After you set a default Service Connect namespace, any new services with Service Connect turned on that are created in the cluster are added as client services in the namespace. This setting only applies to new services that set the enabled parameter to true in the ServiceConnectConfiguration. You can set the namespace of each service individually in the ServiceConnectConfiguration to override this default parameter.

      Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

      • namespacerequired — (String)

        The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace that's used when you create a service and don't specify a Service Connect configuration. The namespace name can include up to 1024 characters. The name is case-sensitive. The name can't include hyphens (-), tilde (~), greater than (>), less than (<), or slash (/).

        If you enter an existing namespace name or ARN, then that namespace will be used. Any namespace type is supported. The namespace must be in this account and this Amazon Web Services Region.

        If you enter a new name, a Cloud Map namespace will be created. Amazon ECS creates a Cloud Map namespace with the "API calls" method of instance discovery only. This instance discovery method is the "HTTP" namespace type in the Command Line Interface. Other types of instance discovery aren't used by Service Connect.

        If you update the cluster with an empty string "" for the namespace name, the cluster configuration for Service Connect is removed. Note that the namespace will remain in Cloud Map and must be deleted separately.

        For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide.

          UPDATE_FAILED

          The capacity provider updates failed.

        • serviceConnectDefaults — (map)

          Use this parameter to set a default Service Connect namespace. After you set a default Service Connect namespace, any new services with Service Connect turned on that are created in the cluster are added as client services in the namespace. This setting only applies to new services that set the enabled parameter to true in the ServiceConnectConfiguration. You can set the namespace of each service individually in the ServiceConnectConfiguration to override this default parameter.

          Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

          • namespace — (String)

            The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace. When you create a service and don't specify a Service Connect configuration, this namespace is used.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

createService(params = {}, callback) ⇒ AWS.Request

Runs and maintains your desired number of tasks from a specified task definition. If the number of tasks running in a service drops below the desiredCount, Amazon ECS runs another copy of the task in the specified cluster. To update an existing service, use UpdateService.

Note: On March 21, 2024, a change was made to resolve the task definition revision before authorization. When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.

In addition to maintaining the desired count of tasks in your service, you can optionally run your service behind one or more load balancers. The load balancers distribute traffic across the tasks that are associated with the service. For more information, see Service load balancing in the Amazon Elastic Container Service Developer Guide.

You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when creating or updating a service. volumeConfigurations is only supported for REPLICA service and not DAEMON service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.

Tasks for services that don't use a load balancer are considered healthy if they're in the RUNNING state. Tasks for services that use a load balancer are considered healthy if they're in the RUNNING state and are reported as healthy by the load balancer.

There are two service scheduler strategies available:

  • REPLICA - The replica scheduling strategy places and maintains your desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. For more information, see Service scheduler concepts in the Amazon Elastic Container Service Developer Guide.

  • DAEMON - The daemon scheduling strategy deploys exactly one task on each active container instance that meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It also stops tasks that don't meet the placement constraints. When using this strategy, you don't need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies. For more information, see Service scheduler concepts in the Amazon Elastic Container Service Developer Guide.

You can optionally specify a deployment configuration for your service. The deployment is initiated by changing properties. For example, the deployment might be initiated by the task definition or by your desired count of a service. You can use UpdateService. The default value for a replica service for minimumHealthyPercent is 100%. The default value for a daemon service for minimumHealthyPercent is 0%.

If a service uses the ECS deployment controller, the minimum healthy percent represents a lower limit on the number of tasks in a service that must remain in the RUNNING state during a deployment. Specifically, it represents it as a percentage of your desired number of tasks (rounded up to the nearest integer). This happens when any of your container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. Using this parameter, you can deploy without using additional cluster capacity. For example, if you set your service to have desired number of four tasks and a minimum healthy percent of 50%, the scheduler might stop two existing tasks to free up cluster capacity before starting two new tasks. If they're in the RUNNING state, tasks for services that don't use a load balancer are considered healthy . If they're in the RUNNING state and reported as healthy by the load balancer, tasks for services that do use a load balancer are considered healthy . The default value for minimum healthy percent is 100%.

If a service uses the ECS deployment controller, the maximum percent parameter represents an upper limit on the number of tasks in a service that are allowed in the RUNNING or PENDING state during a deployment. Specifically, it represents it as a percentage of the desired number of tasks (rounded down to the nearest integer). This happens when any of your container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. Using this parameter, you can define the deployment batch size. For example, if your service has a desired number of four tasks and a maximum percent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default value for maximum percent is 200%.

If a service uses either the CODE_DEPLOY or EXTERNAL deployment controller types and tasks that use the EC2 launch type, the minimum healthy percent and maximum percent values are used only to define the lower and upper limit on the number of the tasks in the service that remain in the RUNNING state. This is while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the minimum healthy percent and maximum percent values aren't used. This is the case even if they're currently visible when describing your service.

When creating a service that uses the EXTERNAL deployment controller, you can specify only parameters that aren't controlled at the task set level. The only required parameter is the service name. You control your services using the CreateTaskSet. For more information, see Amazon ECS deployment types in the Amazon Elastic Container Service Developer Guide.

When the service scheduler launches new tasks, it determines task placement. For information about task placement and task placement strategies, see Amazon ECS task placement in the Amazon Elastic Container Service Developer Guide

Starting April 15, 2023, Amazon Web Services will not onboard new customers to Amazon Elastic Inference (EI), and will help current customers migrate their workloads to options that offer better price and performance. After April 15, 2023, new customers will not be able to launch instances with Amazon EI accelerators in Amazon SageMaker, Amazon ECS, or Amazon EC2. However, customers who have used Amazon EI at least once during the past 30-day period are considered current customers and will be able to continue using the service.

Parameters:

  • params (Object) (defaults to: {})
    • cluster — (String)

      The short name or full Amazon Resource Name (ARN) of the cluster that you run your service on. If you do not specify a cluster, the default cluster is assumed.

    • serviceName — (String)

      The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster, but you can have similarly named services in multiple clusters within a Region or across multiple Regions.

    • taskDefinition — (String)

      The family and revision (family:revision) or full ARN of the task definition to run in your service. If a revision isn't specified, the latest ACTIVE revision is used.

      A task definition must be specified if the service uses either the ECS or CODE_DEPLOY deployment controllers.

      For more information about deployment types, see Amazon ECS deployment types.

    • loadBalancers — (Array<map>)

      A load balancer object representing the load balancers to use with your service. For more information, see Service load balancing in the Amazon Elastic Container Service Developer Guide.

      If the service uses the rolling update (ECS) deployment controller and using either an Application Load Balancer or Network Load Balancer, you must specify one or more target group ARNs to attach to the service. The service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

      If the service uses the CODE_DEPLOY deployment controller, the service is required to use either an Application Load Balancer or Network Load Balancer. When creating an CodeDeploy deployment group, you specify two target groups (referred to as a targetGroupPair). During a deployment, CodeDeploy determines which task set in your service has the status PRIMARY, and it associates one target group with it. Then, it also associates the other target group with the replacement task set. The load balancer can also have up to two listeners: a required listener for production traffic and an optional listener that you can use to perform validation tests with Lambda functions before routing production traffic to it.

      If you use the CODE_DEPLOY deployment controller, these values can be changed when updating the service.

      For Application Load Balancers and Network Load Balancers, this object must contain the load balancer target group ARN, the container name, and the container port to access from the load balancer. The container name must be as it appears in a container definition. The load balancer name parameter must be omitted. When a task from this service is placed on a container instance, the container instance and port combination is registered as a target in the target group that's specified here.

      For Classic Load Balancers, this object must contain the load balancer name, the container name , and the container port to access from the load balancer. The container name must be as it appears in a container definition. The target group ARN parameter must be omitted. When a task from this service is placed on a container instance, the container instance is registered with the load balancer that's specified here.

      Services with tasks that use the awsvpc network mode (for example, those with the Fargate launch type) only support Application Load Balancers and Network Load Balancers. Classic Load Balancers aren't supported. Also, when you create any target groups for these services, you must choose ip as the target type, not instance. This is because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.

      • targetGroupArn — (String)

        The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

        A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

        For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

        For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.

        If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance. Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

      • loadBalancerName — (String)

        The name of the load balancer to associate with the Amazon ECS service or task set.

        If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

      • containerName — (String)

        The name of the container (as it appears in a container definition) to associate with the load balancer.

        You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

      • containerPort — (Integer)

        The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

    • serviceRegistries — (Array<map>)

      The details of the service discovery registry to associate with this service. For more information, see Service discovery.

      Note: Each service may be associated with one service registry. Multiple service registries for each service isn't supported.
      • registryArn — (String)

        The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.

      • port — (Integer)

        The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.

      • containerName — (String)

        The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

      • containerPort — (Integer)

        The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

    • desiredCount — (Integer)

      The number of instantiations of the specified task definition to place and keep running in your service.

      This is required if schedulingStrategy is REPLICA or isn't specified. If schedulingStrategy is DAEMON then this isn't required.

    • clientToken — (String)

      An identifier that you provide to ensure the idempotency of the request. It must be unique and is case sensitive. Up to 36 ASCII characters in the range of 33-126 (inclusive) are allowed.

    • launchType — (String)

      The infrastructure that you run your service on. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

      The FARGATE launch type runs your tasks on Fargate On-Demand infrastructure.

      Note: Fargate Spot infrastructure is available for use but a capacity provider strategy must be used. For more information, see Fargate capacity providers in the Amazon ECS Developer Guide.

      The EC2 launch type runs your tasks on Amazon EC2 instances registered to your cluster.

      The EXTERNAL launch type runs your tasks on your on-premises server or virtual machine (VM) capacity registered to your cluster.

      A service can use either a launch type or a capacity provider strategy. If a launchType is specified, the capacityProviderStrategy parameter must be omitted.

      Possible values include:
      • "EC2"
      • "FARGATE"
      • "EXTERNAL"
    • capacityProviderStrategy — (Array<map>)

      The capacity provider strategy to use for the service.

      If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.

      A capacity provider strategy may contain a maximum of 6 capacity providers.

      • capacityProviderrequired — (String)

        The short name of the capacity provider.

      • weight — (Integer)

        The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

        If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

        An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

      • base — (Integer)

        The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

    • platformVersion — (String)

      The platform version that your tasks in the service are running on. A platform version is specified only for tasks using the Fargate launch type. If one isn't specified, the LATEST platform version is used. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

    • role — (String)

      The name or full Amazon Resource Name (ARN) of the IAM role that allows Amazon ECS to make calls to your load balancer on your behalf. This parameter is only permitted if you are using a load balancer with your service and your task definition doesn't use the awsvpc network mode. If you specify the role parameter, you must also specify a load balancer object with the loadBalancers parameter.

      If your account has already created the Amazon ECS service-linked role, that role is used for your service unless you specify a role here. The service-linked role is required if your task definition uses the awsvpc network mode or if the service is configured to use service discovery, an external deployment controller, multiple target groups, or Elastic Inference accelerators in which case you don't specify a role here. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

      If your specified role has a path other than /, then you must either specify the full role ARN (this is recommended) or prefix the role name with the path. For example, if a role with the name bar has a path of /foo/ then you would specify /foo/bar as the role name. For more information, see Friendly names and paths in the IAM User Guide.

    • deploymentConfiguration — (map)

      Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.

      • deploymentCircuitBreaker — (map)
        Note: The deployment circuit breaker can only be used for services using the rolling update (ECS) deployment type.

        The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide

        • enablerequired — (Boolean)

          Determines whether to use the deployment circuit breaker logic for the service.

        • rollbackrequired — (Boolean)

          Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

      • maximumPercent — (Integer)

        If a service is using the rolling update (ECS) deployment type, the maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.

        If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.

      • minimumHealthyPercent — (Integer)

        If a service is using the rolling update (ECS) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.

        For services that do not use a load balancer, the following should be noted:

        • A service is considered healthy if all essential containers within the tasks in the service pass their health checks.

        • If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.

        • If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.

        For services that do use a load balancer, the following should be noted:

        • If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

        • If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

        The default value for a replica service for minimumHealthyPercent is 100%. The default minimumHealthyPercent value for a service using the DAEMON service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.

        The minimum number of healthy tasks during a deployment is the desiredCount multiplied by the minimumHealthyPercent/100, rounded up to the nearest integer value.

        If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

      • alarms — (map)

        Information about the CloudWatch alarms.

        • alarmNamesrequired — (Array<String>)

          One or more CloudWatch alarm names. Use a "," to separate the alarms.

        • enablerequired — (Boolean)

          Determines whether to use the CloudWatch alarm option in the service deployment process.

        • rollbackrequired — (Boolean)

          Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is used, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

    • placementConstraints — (Array<map>)

      An array of placement constraint objects to use for tasks in your service. You can specify a maximum of 10 constraints for each task. This limit includes constraints in the task definition and those specified at runtime.

      • type — (String)

        The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.

        Possible values include:
        • "distinctInstance"
        • "memberOf"
      • expression — (String)

        A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is distinctInstance. For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide.

    • placementStrategy — (Array<map>)

      The placement strategy objects to use for tasks in your service. You can specify a maximum of 5 strategy rules for each service.

      • type — (String)

        The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that's specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.

        Possible values include:
        • "random"
        • "spread"
        • "binpack"
      • field — (String)

        The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host, which has the same effect), or any platform or custom attribute that's applied to a container instance, such as attribute:ecs.availability-zone. For the binpack placement strategy, valid values are cpu and memory. For the random placement strategy, this field is not used.

    • networkConfiguration — (map)

      The network configuration for the service. This parameter is required for task definitions that use the awsvpc network mode to receive their own elastic network interface, and it isn't supported for other network modes. For more information, see Task networking in the Amazon Elastic Container Service Developer Guide.

      • awsvpcConfiguration — (map)

        The VPC subnets and security groups that are associated with a task.

        Note: All specified subnets and security groups must be from the same VPC.
        • subnetsrequired — (Array<String>)

          The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per awsvpcConfiguration.

          Note: All specified subnets must be from the same VPC.
        • securityGroups — (Array<String>)

          The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration.

          Note: All specified security groups must be from the same VPC.
        • assignPublicIp — (String)

          Whether the task's elastic network interface receives a public IP address. The default value is DISABLED.

          Possible values include:
          • "ENABLED"
          • "DISABLED"
    • healthCheckGracePeriodSeconds — (Integer)

      The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started. This is only used when your service is configured to use a load balancer. If your service has a load balancer defined and you don't specify a health check grace period value, the default value of 0 is used.

      If you do not use an Elastic Load Balancing, we recommend that you use the startPeriod in the task definition health check parameters. For more information, see Health check.

      If your service's tasks take a while to start and respond to Elastic Load Balancing health checks, you can specify a health check grace period of up to 2,147,483,647 seconds (about 69 years). During that time, the Amazon ECS service scheduler ignores health check status. This grace period can prevent the service scheduler from marking tasks as unhealthy and stopping them before they have time to come up.

    • schedulingStrategy — (String)

      The scheduling strategy to use for the service. For more information, see Services.

      There are two service scheduler strategies available:

      • REPLICA-The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. This scheduler strategy is required if the service uses the CODE_DEPLOY or EXTERNAL deployment controller types.

      • DAEMON-The daemon scheduling strategy deploys exactly one task on each active container instance that meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks and will stop tasks that don't meet the placement constraints. When you're using this strategy, you don't need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies.

        Note: Tasks using the Fargate launch type or the CODE_DEPLOY or EXTERNAL deployment controller types don't support the DAEMON scheduling strategy.
      Possible values include:
      • "REPLICA"
      • "DAEMON"
    • deploymentController — (map)

      The deployment controller to use for the service. If no deployment controller is specified, the default value of ECS is used.

      • typerequired — (String)

        The deployment controller type to use.

        There are three deployment controller types available:

        ECS

        The rolling update (ECS) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration.

        CODE_DEPLOY

        The blue/green (CODE_DEPLOY) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.

        EXTERNAL

        The external (EXTERNAL) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.

        Possible values include:
        • "ECS"
        • "CODE_DEPLOY"
        • "EXTERNAL"
    • tags — (Array<map>)

      The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define. When a service is deleted, the tags are deleted as well.

      The following basic restrictions apply to tags:

      • Maximum number of tags per resource - 50

      • For each resource, each tag key must be unique, and each tag key can have only one value.

      • Maximum key length - 128 Unicode characters in UTF-8

      • Maximum value length - 256 Unicode characters in UTF-8

      • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

      • Tag keys and values are case-sensitive.

      • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

      • key — (String)

        One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

      • value — (String)

        The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

    • enableECSManagedTags — (Boolean)

      Specifies whether to turn on Amazon ECS managed tags for the tasks within the service. For more information, see Tagging your Amazon ECS resources in the Amazon Elastic Container Service Developer Guide.

      When you use Amazon ECS managed tags, you need to set the propagateTags request parameter.

    • propagateTags — (String)

      Specifies whether to propagate the tags from the task definition to the task. If no value is specified, the tags aren't propagated. Tags can only be propagated to the task during task creation. To add tags to a task after task creation, use the TagResource API action.

      You must set this to a value other than NONE when you use Cost Explorer. For more information, see Amazon ECS usage reports in the Amazon Elastic Container Service Developer Guide.

      The default is NONE.

      Possible values include:
      • "TASK_DEFINITION"
      • "SERVICE"
      • "NONE"
    • enableExecuteCommand — (Boolean)

      Determines whether the execute command functionality is turned on for the service. If true, this enables execute command functionality on all containers in the service tasks.

    • serviceConnectConfiguration — (map)

      The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.

      Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

      • enabledrequired — (Boolean)

        Specifies whether to use Service Connect with this service.

      • namespace — (String)

        The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace for use with Service Connect. The namespace must be in the same Amazon Web Services Region as the Amazon ECS service and cluster. The type of namespace doesn't affect Service Connect. For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide.

      • services — (Array<map>)

        The list of Service Connect service objects. These are names and aliases (also known as endpoints) that are used by other Amazon ECS services to connect to this service.

        This field is not required for a "client" Amazon ECS service that's a member of a namespace only to connect to other services within the namespace. An example of this would be a frontend application that accepts incoming requests from either a load balancer that's attached to the service or by other means.

        An object selects a port from the task definition, assigns a name for the Cloud Map service, and a list of aliases (endpoints) and ports for client applications to refer to this service.

        • portNamerequired — (String)

          The portName must match the name of one of the portMappings from all the containers in the task definition of this Amazon ECS service.

        • discoveryName — (String)

          The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

          If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

        • clientAliases — (Array<map>)

          The list of client aliases for this Service Connect service. You use these to assign names that can be used by client applications. The maximum number of client aliases that you can have in this list is 1.

          Each alias ("endpoint") is a fully-qualified name and port number that other Amazon ECS tasks ("clients") can use to connect to this service.

          Each name and port mapping must be unique within the namespace.

          For each ServiceConnectService, you must provide at least one clientAlias with one port.

          • portrequired — (Integer)

            The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.

            To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

          • dnsName — (String)

            The dnsName is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.

            If this parameter isn't specified, the default value of discoveryName.namespace is used. If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

            To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are database, db, or the lowercase name of a database, such as mysql or redis. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

        • ingressPortOverride — (Integer)

          The port number for the Service Connect proxy to listen on.

          Use the value of this field to bypass the proxy for traffic on the port number specified in the named portMapping in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.

          In awsvpc mode and Fargate, the default value is the container port number. The container port number is in the portMapping in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.

        • timeout — (map)

          A reference to an object that represents the configured timeouts for Service Connect.

          • idleTimeoutSeconds — (Integer)

            The amount of time in seconds a connection will stay active while idle. A value of 0 can be set to disable idleTimeout.

            The idleTimeout default for HTTP/HTTP2/GRPC is 5 minutes.

            The idleTimeout default for TCP is 1 hour.

          • perRequestTimeoutSeconds — (Integer)

            The amount of time waiting for the upstream to respond with a complete response per request. A value of 0 can be set to disable perRequestTimeout. perRequestTimeout can only be set if Service Connect appProtocol isn't TCP. Only idleTimeout is allowed for TCP appProtocol.

        • tls — (map)

          A reference to an object that represents a Transport Layer Security (TLS) configuration.

          • issuerCertificateAuthorityrequired — (map)

            The signer certificate authority.

            • awsPcaAuthorityArn — (String)

              The ARN of the Amazon Web Services Private Certificate Authority certificate.

          • kmsKey — (String)

            The Amazon Web Services Key Management Service key.

          • roleArn — (String)

            The Amazon Resource Name (ARN) of the IAM role that's associated with the Service Connect TLS.

      • logConfiguration — (map)

        The log configuration for the container. This parameter maps to LogConfig in the docker conainer create command and the --log-driver option to docker run.

        By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition.

        Understand the following when specifying a log configuration for your containers.

        • Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent.

          For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

          For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald,syslog, splunk, and awsfirelens.

        • This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.

        • For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide.

        • For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

        • logDriverrequired — (String)

          The log driver to use for the container.

          For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

          For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, syslog, splunk, and awsfirelens.

          For more information about using the awslogs log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.

          For more information about using the awsfirelens log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.

          Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
          Possible values include:
          • "json-file"
          • "syslog"
          • "journald"
          • "gelf"
          • "fluentd"
          • "awslogs"
          • "splunk"
          • "awsfirelens"
        • options — (map<String>)

          The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

        • secretOptions — (Array<map>)

          The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide.

          • namerequired — (String)

            The name of the secret.

          • valueFromrequired — (String)

            The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.

            For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide.

            Note: If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
    • volumeConfigurations — (Array<map>)

      The configuration for a volume specified in the task definition as a volume that is configured at launch time. Currently, the only supported volume type is an Amazon EBS volume.

      • namerequired — (String)

        The name of the volume. This value must match the volume name from the Volume object in the task definition.

      • managedEBSVolume — (map)

        The configuration for the Amazon EBS volume that Amazon ECS creates and manages on your behalf. These settings are used to create each Amazon EBS volume, with one volume created for each task in the service. The Amazon EBS volumes are visible in your account in the Amazon EC2 console once they are created.

        • encrypted — (Boolean)

          Indicates whether the volume should be encrypted. If no value is specified, encryption is turned on by default. This parameter maps 1:1 with the Encrypted parameter of the CreateVolume API in the Amazon EC2 API Reference.

        • kmsKeyId — (String)

          The Amazon Resource Name (ARN) identifier of the Amazon Web Services Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no Amazon Web Services Key Management Service key is specified, the default Amazon Web Services managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the KmsKeyId parameter of the CreateVolume API in the Amazon EC2 API Reference.

          Amazon Web Services authenticates the Amazon Web Services Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails.

        • volumeType — (String)

          The volume type. This parameter maps 1:1 with the VolumeType parameter of the CreateVolume API in the Amazon EC2 API Reference. For more information, see Amazon EBS volume types in the Amazon EC2 User Guide.

          The following are the supported volume types.

            Note: The magnetic volume type is not supported on Fargate.
        • sizeInGiB — (Integer)

          The size of the volume in GiB. You must specify either a volume size or a snapshot ID. If you specify a snapshot ID, the snapshot size is used for the volume size by default. You can optionally specify a volume size greater than or equal to the snapshot size. This parameter maps 1:1 with the Size parameter of the CreateVolume API in the Amazon EC2 API Reference.

          The following are the supported volume size values for each volume type.

          • gp2 and gp3: 1-16,384

          • io1 and io2: 4-16,384

          • st1 and sc1: 125-16,384

          • standard: 1-1,024

        • snapshotId — (String)

          The snapshot that Amazon ECS uses to create the volume. You must specify either a snapshot ID or a volume size. This parameter maps 1:1 with the SnapshotId parameter of the CreateVolume API in the Amazon EC2 API Reference.

        • iops — (Integer)

          The number of I/O operations per second (IOPS). For gp3, io1, and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.

          The following are the supported values for each volume type.

          • gp3: 3,000 - 16,000 IOPS

          • io1: 100 - 64,000 IOPS

          • io2: 100 - 256,000 IOPS

          This parameter is required for io1 and io2 volume types. The default for gp3 volumes is 3,000 IOPS. This parameter is not supported for st1, sc1, or standard volume types.

          This parameter maps 1:1 with the Iops parameter of the CreateVolume API in the Amazon EC2 API Reference.

        • throughput — (Integer)

          The throughput to provision for a volume, in MiB/s, with a maximum of 1,000 MiB/s. This parameter maps 1:1 with the Throughput parameter of the CreateVolume API in the Amazon EC2 API Reference.

          This parameter is only supported for the gp3 volume type.

        • tagSpecifications — (Array<map>)

          The tags to apply to the volume. Amazon ECS applies service-managed tags by default. This parameter maps 1:1 with the TagSpecifications.N parameter of the CreateVolume API in the Amazon EC2 API Reference.

            • key — (String)

              One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

            • value — (String)

              The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

          • propagateTags — (String)

            Determines whether to propagate the tags from the task definition to 
the Amazon EBS volume. Tags can only propagate to a SERVICE specified in 
ServiceVolumeConfiguration. If no value is specified, the tags aren't 
propagated.

            Possible values include:
            • "TASK_DEFINITION"
            • "SERVICE"
            • "NONE"
        • roleArnrequired — (String)

          The ARN of the IAM role to associate with this volume. This is the Amazon ECS infrastructure IAM role that is used to manage your Amazon Web Services infrastructure. We recommend using the Amazon ECS-managed AmazonECSInfrastructureRolePolicyForVolumes IAM policy with this role. For more information, see Amazon ECS infrastructure IAM role in the Amazon ECS Developer Guide.

        • filesystemType — (String)

          The Linux filesystem type for the volume. For volumes created from a snapshot, you must specify the same filesystem type that the volume was using when the snapshot was created. If there is a filesystem type mismatch, the task will fail to start.

          The available filesystem types are
 ext3, ext4, and xfs. If no value is specified, the xfs filesystem type is used by default.

          Possible values include:
          • "ext3"
          • "ext4"
          • "xfs"

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • service — (map)

        The full description of your service following the create call.

        A service will return either a capacityProviderStrategy or launchType parameter, but not both, depending where one was specified when it was created.

        If a service is using the ECS deployment controller, the deploymentController and taskSets parameters will not be returned.

        if the service uses the CODE_DEPLOY deployment controller, the deploymentController, taskSets and deployments parameters will be returned, however the deployments parameter will be an empty list.

        • serviceArn — (String)

          The ARN that identifies the service. For more information about the ARN format, see Amazon Resource Name (ARN) in the Amazon ECS Developer Guide.

        • serviceName — (String)

          The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster. However, you can have similarly named services in multiple clusters within a Region or across multiple Regions.

        • clusterArn — (String)

          The Amazon Resource Name (ARN) of the cluster that hosts the service.

        • loadBalancers — (Array<map>)

          A list of Elastic Load Balancing load balancer objects. It contains the load balancer name, the container name, and the container port to access from the load balancer. The container name is as it appears in a container definition.

          • targetGroupArn — (String)

            The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

            A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

            For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

            For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.

            If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance. Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

          • loadBalancerName — (String)

            The name of the load balancer to associate with the Amazon ECS service or task set.

            If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

          • containerName — (String)

            The name of the container (as it appears in a container definition) to associate with the load balancer.

            You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

          • containerPort — (Integer)

            The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

        • serviceRegistries — (Array<map>)

          The details for the service discovery registries to assign to this service. For more information, see Service Discovery.

          • registryArn — (String)

            The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.

          • port — (Integer)

            The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.

          • containerName — (String)

            The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

          • containerPort — (Integer)

            The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

        • status — (String)

          The status of the service. The valid values are ACTIVE, DRAINING, or INACTIVE.

        • desiredCount — (Integer)

          The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService.

        • runningCount — (Integer)

          The number of tasks in the cluster that are in the RUNNING state.

        • pendingCount — (Integer)

          The number of tasks in the cluster that are in the PENDING state.

        • launchType — (String)

          The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.

          Possible values include:
          • "EC2"
          • "FARGATE"
          • "EXTERNAL"
        • capacityProviderStrategy — (Array<map>)

          The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.

          • capacityProviderrequired — (String)

            The short name of the capacity provider.

          • weight — (Integer)

            The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

            If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

            An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

          • base — (Integer)

            The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

        • platformVersion — (String)

          The platform version to run your service on. A platform version is only specified for tasks that are hosted on Fargate. If one isn't specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.

        • platformFamily — (String)

          The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.

          All tasks that run as part of this service must use the same platformFamily value as the service (for example, LINUX).

        • taskDefinition — (String)

          The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.

        • deploymentConfiguration — (map)

          Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.

          • deploymentCircuitBreaker — (map)
            Note: The deployment circuit breaker can only be used for services using the rolling update (ECS) deployment type.

            The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide

            • enablerequired — (Boolean)

              Determines whether to use the deployment circuit breaker logic for the service.

            • rollbackrequired — (Boolean)

              Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

          • maximumPercent — (Integer)

            If a service is using the rolling update (ECS) deployment type, the maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.

            If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.

          • minimumHealthyPercent — (Integer)

            If a service is using the rolling update (ECS) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.

            For services that do not use a load balancer, the following should be noted:

            • A service is considered healthy if all essential containers within the tasks in the service pass their health checks.

            • If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.

            • If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.

            For services that do use a load balancer, the following should be noted:

            • If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

            • If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

            The default value for a replica service for minimumHealthyPercent is 100%. The default minimumHealthyPercent value for a service using the DAEMON service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.

            The minimum number of healthy tasks during a deployment is the desiredCount multiplied by the minimumHealthyPercent/100, rounded up to the nearest integer value.

            If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

          • alarms — (map)

            Information about the CloudWatch alarms.

            • alarmNamesrequired — (Array<String>)

              One or more CloudWatch alarm names. Use a "," to separate the alarms.

            • enablerequired — (Boolean)

              Determines whether to use the CloudWatch alarm option in the service deployment process.

            • rollbackrequired — (Boolean)

              Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is used, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

        • taskSets — (Array<map>)

          Information about a set of Amazon ECS tasks in either an CodeDeploy or an EXTERNAL deployment. An Amazon ECS task set includes details such as the desired number of tasks, how many tasks are running, and whether the task set serves production traffic.

          • startedBy — (String)

            The tag specified when a task set is started. If an CodeDeploy deployment created the task set, the startedBy parameter is CODE_DEPLOY. If an external deployment created the task set, the startedBy field isn't used.

          • externalId — (String)

            The external ID associated with the task set.

            If an CodeDeploy deployment created a task set, the externalId parameter contains the CodeDeploy deployment ID.

            If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute.

          • status — (String)

            The status of the task set. The following describes each state.

            PRIMARY

            The task set is serving production traffic.

            ACTIVE

            The task set isn't serving production traffic.

            DRAINING

            The tasks in the task set are being stopped, and their corresponding targets are being deregistered from their target group.

          • taskDefinition — (String)

            The task definition that the task set is using.

          • computedDesiredCount — (Integer)

            The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.

          • pendingCount — (Integer)

            The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it's restarted after being in the STOPPED state.

          • runningCount — (Integer)

            The number of tasks in the task set that are in the RUNNING status during a deployment. A task in the RUNNING state is running and ready for use.

          • createdAt — (Date)

            The Unix timestamp for the time when the task set was created.

          • updatedAt — (Date)

            The Unix timestamp for the time when the task set was last updated.

          • launchType — (String)

            The launch type the tasks in the task set are using. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

            Possible values include:
            • "EC2"
            • "FARGATE"
            • "EXTERNAL"
          • capacityProviderStrategy — (Array<map>)

            • capacityProviderrequired — (String)

              The short name of the capacity provider.

            • weight — (Integer)

              The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

              If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

              An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

            • base — (Integer)

              The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

          • platformVersion — (String)

            The Fargate platform version where the tasks in the task set are running. A platform version is only specified for tasks run on Fargate. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

          • platformFamily — (String)

            The operating system that your tasks in the set are running on. A platform family is specified only for tasks that use the Fargate launch type.

              • securityGroups — (Array<String>)

                The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration.

                Note: All specified security groups must be from the same VPC.
              • assignPublicIp — (String)

                Whether the task's elastic network interface receives a public IP address. The default value is DISABLED.

                Possible values include:
                • "ENABLED"
                • "DISABLED"
          • loadBalancers — (Array<map>)

            Details on a load balancer that are used with a task set.

            • targetGroupArn — (String)

              The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

              A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

              For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

              For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.

              If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance. Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

            • loadBalancerName — (String)

              The name of the load balancer to associate with the Amazon ECS service or task set.

              If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

              The name of the container (as it appears in a container definition) to associate with the load balancer.

              You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

            • containerPort — (Integer)

              The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

          • serviceRegistries — (Array<map>)

            The details for the service discovery registries to assign to this task set. For more information, see Service discovery.

            • containerName — (String)

              The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

            • containerPort — (Integer)

              The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

          • scale — (map)

            A floating-point percentage of your desired number of tasks to place and keep running in the task set.

            • value — (Float)

              The value, specified as a percent total of a service's desiredCount, to scale the task set. Accepted values are numbers between 0 and 100.

            • The task runningCount is equal to the computedDesiredCount.

            • The pendingCount is 0.

            • There are no tasks that are running on container instances in the DRAINING status.

            • All tasks are reporting a healthy status from the load balancers, service discovery, and container health checks.

            If any of those conditions aren't met, the stability status returns STABILIZING.

            Possible values include:
            • "STEADY_STATE"
            • "STABILIZING"
          • stabilityStatusAt — (Date)

          • tags — (Array<map>)

            The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value. You define both.

            The following basic restrictions apply to tags:

            • Maximum number of tags per resource - 50

            • For each resource, each tag key must be unique, and each tag key can have only one value.

            • Maximum key length - 128 Unicode characters in UTF-8

            • Maximum value length - 256 Unicode characters in UTF-8

            • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

            • Tag keys and values are case-sensitive.

            • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

            • key — (String)

              One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

        • deployments — (Array<map>)

          The current state of deployments for the service.

          • id — (String)

            The ID of the deployment.

          • status — (String)

            The status of the deployment. The following describes each state.

            PRIMARY

            The most recent deployment of a service.

            ACTIVE

            A service deployment that still has running tasks, but are in the process of being replaced with a new PRIMARY deployment.

            INACTIVE

            A deployment that has been completely replaced.

          • taskDefinition — (String)

            The most recent task definition that was specified for the tasks in the service to use.

          • desiredCount — (Integer)

            The most recent desired count of tasks that was specified for the service to deploy or maintain.

          • pendingCount — (Integer)

            The number of tasks in the deployment that are in the PENDING status.

          • runningCount — (Integer)

            The number of tasks in the deployment that are in the RUNNING status.

          • failedTasks — (Integer)

            The number of consecutively failed tasks in the deployment. A task is considered a failure if the service scheduler can't launch the task, the task doesn't transition to a RUNNING state, or if it fails any of its defined health checks and is stopped.

            Note: Once a service deployment has one or more successfully running tasks, the failed task count resets to zero and stops being evaluated.
          • createdAt — (Date)

            The Unix timestamp for the time when the service deployment was created.

          • updatedAt — (Date)

            The Unix timestamp for the time when the service deployment was last updated.

          • capacityProviderStrategy — (Array<map>)

            The capacity provider strategy that the deployment is using.

            • capacityProviderrequired — (String)

              The short name of the capacity provider.

            • weight — (Integer)

              The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

              If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

              An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

            • base — (Integer)

              The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

          • launchType — (String)

            The rollout state of the deployment. When a service deployment is started, it begins in an IN_PROGRESS state. When the service reaches a steady state, the deployment transitions to a COMPLETED state. If the service fails to reach a steady state and circuit breaker is turned on, the deployment transitions to a FAILED state. A deployment in FAILED state doesn't launch any new tasks. For more information, see DeploymentCircuitBreaker.

            Possible values include:

            The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.

            Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

            • enabledrequired — (Boolean)

              Specifies whether to use Service Connect with this service.

            • namespace — (String)

              The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace for use with Service Connect. The namespace must be in the same Amazon Web Services Region as the Amazon ECS service and cluster. The type of namespace doesn't affect Service Connect. For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide.

            • services — (Array<map>)

              The list of Service Connect service objects. These are names and aliases (also known as endpoints) that are used by other Amazon ECS services to connect to this service.

              This field is not required for a "client" Amazon ECS service that's a member of a namespace only to connect to other services within the namespace. An example of this would be a frontend application that accepts incoming requests from either a load balancer that's attached to the service or by other means.

              An object selects a port from the task definition, assigns a name for the Cloud Map service, and a list of aliases (endpoints) and ports for client applications to refer to this service.

              • portNamerequired — (String)

                The portName must match the name of one of the portMappings from all the containers in the task definition of this Amazon ECS service.

              • discoveryName — (String)

                The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

                If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

              • clientAliases — (Array<map>)

                The list of client aliases for this Service Connect service. You use these to assign names that can be used by client applications. The maximum number of client aliases that you can have in this list is 1.

                Each alias ("endpoint") is a fully-qualified name and port number that other Amazon ECS tasks ("clients") can use to connect to this service.

                Each name and port mapping must be unique within the namespace.

                For each ServiceConnectService, you must provide at least one clientAlias with one port.

                • portrequired — (Integer)

                  The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.

                  To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

                • dnsName — (String)

                  The dnsName is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.

                  If this parameter isn't specified, the default value of discoveryName.namespace is used. If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

                  To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are database, db, or the lowercase name of a database, such as mysql or redis. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

              • ingressPortOverride — (Integer)

                The port number for the Service Connect proxy to listen on.

                Use the value of this field to bypass the proxy for traffic on the port number specified in the named portMapping in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.

                In awsvpc mode and Fargate, the default value is the container port number. The container port number is in the portMapping in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.

              • timeout — (map)

                A reference to an object that represents the configured timeouts for Service Connect.

                • idleTimeoutSeconds — (Integer)

                  The amount of time in seconds a connection will stay active while idle. A value of 0 can be set to disable idleTimeout.

                  The idleTimeout default for HTTP/HTTP2/GRPC is 5 minutes.

                  The idleTimeout default for TCP is 1 hour.

                • perRequestTimeoutSeconds — (Integer)

                  The amount of time waiting for the upstream to respond with a complete response per request. A value of 0 can be set to disable perRequestTimeout. perRequestTimeout can only be set if Service Connect appProtocol isn't TCP. Only idleTimeout is allowed for TCP appProtocol.

              • tls — (map)

                A reference to an object that represents a Transport Layer Security (TLS) configuration.

            • logConfiguration — (map)

              The log configuration for the container. This parameter maps to LogConfig in the docker conainer create command and the --log-driver option to docker run.

              By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition.

              Understand the following when specifying a log configuration for your containers.

              • Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent.

                For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

                For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald,syslog, splunk, and awsfirelens.

              • This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.

              • For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide.

              • For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

              • logDriverrequired — (String)

                The log driver to use for the container.

                For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

                For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, syslog, splunk, and awsfirelens.

                For more information about using the awslogs log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.

                For more information about using the awsfirelens log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.

                Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
                Possible values include:
                • "json-file"
                • "syslog"
                • "journald"

                  For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide.

                  Note: If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
          • serviceConnectResources — (Array<map>)

            The list of Service Connect resources that are associated with this deployment. Each list entry maps a discovery name to a Cloud Map service name.

The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

              If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

            • discoveryArn — (String)

              The Amazon Resource Name (ARN) for the namespace in Cloud Map that matches the discovery name for this Service Connect resource. You can use this ARN in other integrations with Cloud Map. However, Service Connect can't ensure connectivity outside of Amazon ECS.

          • volumeConfigurations — (Array<map>)

            The details of the volume that was configuredAtLaunch. You can configure different settings like the size, throughput, volumeType, and ecryption in ServiceManagedEBSVolumeConfiguration. The name of the volume must match the name from the task definition.

            • namerequired — (String)

              The name of the volume. This value must match the volume name from the Volume object in the task definition.

            • managedEBSVolume — (map)

              The configuration for the Amazon EBS volume that Amazon ECS creates and manages on your behalf. These settings are used to create each Amazon EBS volume, with one volume created for each task in the service. The Amazon EBS volumes are visible in your account in the Amazon EC2 console once they are created.

              • encrypted — (Boolean)

                Indicates whether the volume should be encrypted. If no value is specified, encryption is turned on by default. This parameter maps 1:1 with the Encrypted parameter of the CreateVolume API in the Amazon EC2 API Reference.

              • kmsKeyId — (String)

                The Amazon Resource Name (ARN) identifier of the Amazon Web Services Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no Amazon Web Services Key Management Service key is specified, the default Amazon Web Services managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the KmsKeyId parameter of the CreateVolume API in the Amazon EC2 API Reference.

                Amazon Web Services authenticates the Amazon Web Services Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails.

              • volumeType — (String)

                The volume type. This parameter maps 1:1 with the VolumeType parameter of the CreateVolume API in the Amazon EC2 API Reference. For more information, see Amazon EBS volume types in the Amazon EC2 User Guide.

              • sizeInGiB — (Integer)

                The size of the volume in GiB. You must specify either a volume size or a snapshot ID. If you specify a snapshot ID, the snapshot size is used for the volume size by default. You can optionally specify a volume size greater than or equal to the snapshot size. This parameter maps 1:1 with the Size parameter of the CreateVolume API in the Amazon EC2 API Reference.

                The following are the supported volume size values for each volume type.

                • gp2 and gp3: 1-16,384

                • io1 and io2: 4-16,384

              • snapshotId — (String)

                The snapshot that Amazon ECS uses to create the volume. You must specify either a snapshot ID or a volume size. This parameter maps 1:1 with the SnapshotId parameter of the CreateVolume API in the Amazon EC2 API Reference.

              • iops — (Integer)

                The number of I/O operations per second (IOPS). For gp3, io1, and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.

                The following are the supported values for each volume type.

                • gp3: 3,000 - 16,000 IOPS

                • io1: 100 - 64,000 IOPS

                • io2: 100 - 256,000 IOPS

                This parameter is required for io1 and io2 volume types. The default for gp3 volumes is 3,000 IOPS. This parameter is not supported for st1, sc1, or standard volume types.

                This parameter maps 1:1 with the Iops parameter of the CreateVolume API in the Amazon EC2 API Reference.

              • throughput — (Integer)

                The throughput to provision for a volume, in MiB/s, with a maximum of 1,000 MiB/s. This parameter maps 1:1 with the Throughput parameter of the CreateVolume API in the Amazon EC2 API Reference.

                This parameter is only supported for the gp3 volume type.

              • tagSpecifications — (Array<map>)

                The tags to apply to the volume. Amazon ECS applies service-managed tags by default. This parameter maps 1:1 with the TagSpecifications.N parameter of the CreateVolume API in the Amazon EC2 API Reference.

                • resourceTyperequired — (String)

                  The type of volume resource.

                    One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

                  • value — (String)

                    The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

                • propagateTags — (String)

                  Determines whether to propagate the tags from the task definition to 
the Amazon EBS volume. Tags can only propagate to a SERVICE specified in 
ServiceVolumeConfiguration. If no value is specified, the tags aren't 
propagated.

                  Possible values include:
                  • "TASK_DEFINITION"
                  • "SERVICE"

              • roleArnrequired — (String)

                The ARN of the IAM role to associate with this volume. This is the Amazon ECS infrastructure IAM role that is used to manage your Amazon Web Services infrastructure. We recommend using the Amazon ECS-managed AmazonECSInfrastructureRolePolicyForVolumes IAM policy with this role. For more information, see Amazon ECS infrastructure IAM role in the Amazon ECS Developer Guide.

              • filesystemType — (String)

                The Linux filesystem type for the volume. For volumes created from a snapshot, you must specify the same filesystem type that the volume was using when the snapshot was created. If there is a filesystem type mismatch, the task will fail to start.

                The available filesystem types are
 ext3, ext4, and xfs. If no value is specified, the xfs filesystem type is used by default.

                Possible values include:
                • "ext3"
                • "ext4"

            The event message.

        • createdAt — (Date)

          The Unix timestamp for the time when the service was created.

        • placementConstraints — (Array<map>)

          The placement constraints for the tasks in the service.

          • type — (String)

            The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.

            Possible values include:
            • "distinctInstance"
            • "memberOf"
          • expression — (String)

          The placement strategy that determines how tasks for the service are placed.

          • type — (String)

            The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that's specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.

            Possible values include:
            • "random"
            • "spread"
            • "binpack"
          • field — (String)

            The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host, which has the same effect), or any platform or custom attribute that's applied to a container instance, such as attribute:ecs.availability-zone. For the binpack placement strategy, valid values are cpu and memory. For the random placement strategy, this field is not used.

        • networkConfiguration — (map)

          The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.

          • awsvpcConfiguration — (map)

            The VPC subnets and security groups that are associated with a task.

            Note: All specified subnets and security groups must be from the same VPC.
            • subnetsrequired — (Array<String>)

              The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per awsvpcConfiguration.

            • securityGroups — (Array<String>)

              The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration.

              Note: All specified security groups must be from the same VPC.
            • assignPublicIp — (String)

              Whether the task's elastic network interface receives a public IP address. The default value is DISABLED.

              Possible values include:
              • "ENABLED"
              • "DISABLED"
        • healthCheckGracePeriodSeconds — (Integer)

          The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started.

        • schedulingStrategy — (String)

          The scheduling strategy to use for the service. For more information, see Services.

          There are two service scheduler strategies available.

          • REPLICA-The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions.

          • DAEMON-The daemon scheduling strategy deploys exactly one task on each active container instance. This task meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It stop tasks that don't meet the placement constraints.

            Note: Fargate tasks don't support the DAEMON scheduling strategy.
          Possible values include:
          • "REPLICA"
          • "DAEMON"
        • deploymentController — (map)

          The deployment controller type the service is using.

          • typerequired — (String)

            The deployment controller type to use.

            There are three deployment controller types available:

            ECS

            The rolling update (ECS) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration.

            CODE_DEPLOY

            The blue/green (CODE_DEPLOY) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.

            EXTERNAL

            The external (EXTERNAL) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.

            Possible values include:
            • "ECS"
            • "CODE_DEPLOY"
            • "EXTERNAL"
        • tags — (Array<map>)

          The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value. You define bot the key and value.

          The following basic restrictions apply to tags:

          • Maximum number of tags per resource - 50

          • For each resource, each tag key must be unique, and each tag key can have only one value.

          • Maximum key length - 128 Unicode characters in UTF-8

          • Maximum value length - 256 Unicode characters in UTF-8

          • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

          • Tag keys and values are case-sensitive.

          • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

          • key — (String)

            One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

          • value — (String)

            The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

        • createdBy — (String)

          The principal that created the service.

        • enableECSManagedTags — (Boolean)

          Determines whether to use Amazon ECS managed tags for the tasks in the service. For more information, see Tagging Your Amazon ECS Resources in the Amazon Elastic Container Service Developer Guide.

        • propagateTags — (String)

          Determines whether to propagate the tags from the task definition or the service to the task. If no value is specified, the tags aren't propagated.

          Possible values include:
          • "TASK_DEFINITION"
          • "SERVICE"
          • "NONE"
        • enableExecuteCommand — (Boolean)

          Determines whether the execute command functionality is turned on for the service. If true, the execute command functionality is turned on for all containers in tasks as part of the service.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

createTaskSet(params = {}, callback) ⇒ AWS.Request

Create a task set in the specified cluster and service. This is used when a service uses the EXTERNAL deployment controller type. For more information, see Amazon ECS deployment types in the Amazon Elastic Container Service Developer Guide.

Note: On March 21, 2024, a change was made to resolve the task definition revision before authorization. When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.

For information about the maximum number of task sets and other quotas, see Amazon ECS service quotas in the Amazon Elastic Container Service Developer Guide.

      The short name or full Amazon Resource Name (ARN) of the cluster that hosts the service to create the task set in.

    • externalId — (String)

      An optional non-unique tag that identifies this task set in external systems. If the task set is associated with a service discovery registry, the tasks in this task set will have the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute set to the provided value.

    • taskDefinition — (String)

      The task definition for the tasks in the task set to use. If a revision isn't specified, the latest ACTIVE revision is used.

    • networkConfiguration — (map)

      An object representing the network configuration for a task set.

      • awsvpcConfiguration — (map)

        The VPC subnets and security groups that are associated with a task.

        Note: All specified subnets and security groups must be from the same VPC.
        • subnetsrequired — (Array<String>)

          The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per awsvpcConfiguration.

          Note: All specified subnets must be from the same VPC.
        • securityGroups — (Array<String>)

          The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration.

          Note: All specified security groups must be from the same VPC.
        • assignPublicIp — (String)

          Whether the task's elastic network interface receives a public IP address. The default value is DISABLED.

          Possible values include:
          • "ENABLED"
          • "DISABLED"
    • loadBalancers — (Array<map>)

      A load balancer object representing the load balancer to use with the task set. The supported load balancer types are either an Application Load Balancer or a Network Load Balancer.

      • targetGroupArn — (String)

        The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

        A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

        For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

        For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.

        If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance. Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

      • loadBalancerName — (String)

        The name of the load balancer to associate with the Amazon ECS service or task set.

        If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

      • containerName — (String)

        The name of the container (as it appears in a container definition) to associate with the load balancer.

        You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

      • containerPort — (Integer)

        The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

    • serviceRegistries — (Array<map>)

      The details of the service discovery registries to assign to this task set. For more information, see Service discovery.

      • registryArn — (String)

        The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.

      • port — (Integer)

        The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.

      • containerName — (String)

        The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

      • containerPort — (Integer)

        The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

    • launchType — (String)

      The launch type that new tasks in the task set uses. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

      If a launchType is specified, the capacityProviderStrategy parameter must be omitted.

      Possible values include:
      • "EC2"
      • "FARGATE"
      • "EXTERNAL"
    • capacityProviderStrategy — (Array<map>)

      The capacity provider strategy to use for the task set.

      A capacity provider strategy consists of one or more capacity providers along with the base and weight to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster. Only capacity providers with an ACTIVE or UPDATING status can be used.

      If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.

      If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProviderProviderAPI operation.

      To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.

      The PutClusterCapacityProviders API operation is used to update the list of available capacity providers for a cluster after the cluster is created.

      • capacityProviderrequired — (String)

        The short name of the capacity provider.

      • weight — (Integer)

        The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

        If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

        An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

      • base — (Integer)

        The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

    • platformVersion — (String)

      The platform version that the tasks in the task set uses. A platform version is specified only for tasks using the Fargate launch type. If one isn't specified, the LATEST platform version is used.

    • scale — (map)

      A floating-point percentage of the desired number of tasks to place and keep running in the task set.

      • value — (Float)

        The value, specified as a percent total of a service's desiredCount, to scale the task set. Accepted values are numbers between 0 and 100.

      • unit — (String)

        The unit of measure for the scale value.

        Possible values include:
        • "PERCENT"
    • clientToken — (String)

      An identifier that you provide to ensure the idempotency of the request. It must be unique and is case sensitive. Up to 36 ASCII characters in the range of 33-126 (inclusive) are allowed.

    • tags — (Array<map>)

      The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value. You define both. When a service is deleted, the tags are deleted.

      The following basic restrictions apply to tags:

      • Maximum number of tags per resource - 50

      • For each resource, each tag key must be unique, and each tag key can have only one value.

      • Maximum key length - 128 Unicode characters in UTF-8

      • Maximum value length - 256 Unicode characters in UTF-8

      • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

      • Tag keys and values are case-sensitive.

      • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

      • key — (String)

        One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

      • value — (String)

        • startedBy — (String)

          The tag specified when a task set is started. If an CodeDeploy deployment created the task set, the startedBy parameter is CODE_DEPLOY. If an external deployment created the task set, the startedBy field isn't used.

        • externalId — (String)

          The external ID associated with the task set.

          If an CodeDeploy deployment created a task set, the externalId parameter contains the CodeDeploy deployment ID.

          If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute.

        • status — (String)

          The status of the task set. The following describes each state.

          PRIMARY

          The task set is serving production traffic.

          ACTIVE

          The task set isn't serving production traffic.

          DRAINING

          The tasks in the task set are being stopped, and their corresponding targets are being deregistered from their target group.

        • taskDefinition — (String)

          The task definition that the task set is using.

        • computedDesiredCount — (Integer)

          The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.

        • pendingCount — (Integer)

          The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it's restarted after being in the STOPPED state.

        • runningCount — (Integer)

          The number of tasks in the task set that are in the RUNNING status during a deployment. A task in the RUNNING state is running and ready for use.

        • createdAt — (Date)

          The Unix timestamp for the time when the task set was created.

        • updatedAt — (Date)

          The Unix timestamp for the time when the task set was last updated.

        • launchType — (String)

          The launch type the tasks in the task set are using. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

          Possible values include:
          • "EC2"
          • "FARGATE"
          • "EXTERNAL"

          • capacityProviderrequired — (String)

            The short name of the capacity provider.

          • weight — (Integer)

            The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

            If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

            An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

          • base — (Integer)

            The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

        • platformVersion — (String)

          The Fargate platform version where the tasks in the task set are running. A platform version is only specified for tasks run on Fargate. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

        • platformFamily — (String)

          The operating system that your tasks in the set are running on. A platform family is specified only for tasks that use the Fargate launch type.

          All tasks in the set must have the same value.

        • networkConfiguration — (map)

          The network configuration for the task set.

          • awsvpcConfiguration — (map)

            The VPC subnets and security groups that are associated with a task.

            Note: All specified subnets and security groups must be from the same VPC.
            • subnetsrequired — (Array<String>)

              The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per awsvpcConfiguration.

              Note: All specified subnets must be from the same VPC.
            • securityGroups — (Array<String>)

              The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration.

              Note: All specified security groups must be from the same VPC.
            • assignPublicIp — (String)

              Whether the task's elastic network interface receives a public IP address. The default value is DISABLED.

              • "DISABLED"
        • loadBalancers — (Array<map>)

          Details on a load balancer that are used with a task set.

          • targetGroupArn — (String)

            The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

            A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

            For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

            For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.

            If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance. Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

          • loadBalancerName — (String)

            The name of the load balancer to associate with the Amazon ECS service or task set.

            If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

          • containerPort — (Integer)

            The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

        • serviceRegistries — (Array<map>)

          The details for the service discovery registries to assign to this task set. For more information, see Service discovery.

          • registryArn — (String)

            The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.

          • port — (Integer)

            The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.

          • containerName — (String)

            The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

          • containerPort — (Integer)

If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

        • scale — (map)

          A floating-point percentage of your desired number of tasks to place and keep running in the task set.

          • value — (Float)

            The value, specified as a percent total of a service's desiredCount, to scale the task set. Accepted values are numbers between 0 and 100.

          • unit — (String)

            The unit of measure for the scale value.

            Possible values include:
            • "PERCENT"
        • stabilityStatus — (String)

          The stability status. This indicates whether the task set has reached a steady state. If the following conditions are met, the task set are in STEADY_STATE:

          • The pendingCount is 0.

          • There are no tasks that are running on container instances in the DRAINING status.

          • All tasks are reporting a healthy status from the load balancers, service discovery, and container health checks.

          If any of those conditions aren't met, the stability status returns STABILIZING.

        • tags — (Array<map>)

          The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value. You define both.

          The following basic restrictions apply to tags:

          • Maximum number of tags per resource - 50

          • For each resource, each tag key must be unique, and each tag key can have only one value.

          • Maximum key length - 128 Unicode characters in UTF-8

          • Maximum value length - 256 Unicode characters in UTF-8

          • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

          • Tag keys and values are case-sensitive.

          • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use.

deleteCapacityProvider(params = {}, callback) ⇒ AWS.Request

Deletes the specified capacity provider.

Note: The FARGATE and FARGATE_SPOT capacity providers are reserved and can't be deleted. You can disassociate them from a cluster using either PutCapacityProviderProviders or by deleting the cluster.

Prior to a capacity provider being deleted, the capacity provider must be removed from the capacity provider strategy from all services. The UpdateService API can be used to remove a capacity provider from a service's capacity provider strategy. When updating a service, the forceNewDeployment option can be used to ensure that any tasks using the Amazon EC2 instance capacity provided by the capacity provider are transitioned to use the capacity from the remaining capacity providers.

          The name of the capacity provider.

        • status — (String)

          The current status of the capacity provider. Only capacity providers in an ACTIVE state can be used in a cluster. When a capacity provider is successfully deleted, it has an INACTIVE status.

          Possible values include:
          • "ACTIVE"
          • "INACTIVE"
        • autoScalingGroupProvider — (map)

          The Auto Scaling group settings for the capacity provider.

          • autoScalingGroupArnrequired — (String)

            The Amazon Resource Name (ARN) that identifies the Auto Scaling group, or the Auto Scaling group name.

          • managedScaling — (map)

            The managed scaling settings for the Auto Scaling group capacity provider.

            • status — (String)

              Determines whether to use managed scaling for the capacity provider.

              Possible values include:
              • "ENABLED"
              • "DISABLED"
            • targetCapacity — (Integer)

              The target capacity utilization as a percentage for the capacity provider. The specified value must be greater than 0 and less than or equal to 100. For example, if you want the capacity provider to maintain 10% spare capacity, then that means the utilization is 90%, so use a targetCapacity of 90. The default value of 100 percent results in the Amazon EC2 instances in your Auto Scaling group being completely used.

            • minimumScalingStepSize — (Integer)

              The minimum number of Amazon EC2 instances that Amazon ECS will scale out at one time. The scale in process is not affected by this parameter If this parameter is omitted, the default value of 1 is used.

              When additional capacity is required, Amazon ECS will scale up the minimum scaling step size even if the actual demand is less than the minimum scaling step size.

              If you use a capacity provider with an Auto Scaling group configured with more than one Amazon EC2 instance type or Availability Zone, Amazon ECS will scale up by the exact minimum scaling step size value and will ignore both the maximum scaling step size as well as the capacity demand.

            • maximumScalingStepSize — (Integer)

              The maximum number of Amazon EC2 instances that Amazon ECS will scale out at one time. If this parameter is omitted, the default value of 10000 is used.

            • instanceWarmupPeriod — (Integer)

              The period of time, in seconds, after a newly launched Amazon EC2 instance can contribute to CloudWatch metrics for Auto Scaling group. If this parameter is omitted, the default value of 300 seconds is used.

          • managedTerminationProtection — (String)

            The managed termination protection setting to use for the Auto Scaling group capacity provider. This determines whether the Auto Scaling group has managed termination protection. The default is off.

            When using managed termination protection, managed scaling must also be used otherwise managed termination protection doesn't work.

            When managed termination protection is on, Amazon ECS prevents the Amazon EC2 instances in an Auto Scaling group that contain tasks from being terminated during a scale-in action. The Auto Scaling group and each instance in the Auto Scaling group must have instance protection from scale-in actions on as well. For more information, see Instance Protection in the Auto Scaling User Guide.

            When managed termination protection is off, your Amazon EC2 instances aren't protected from termination when the Auto Scaling group scales in.

            Possible values include:
            • "ENABLED"
            • "DISABLED"
          • managedDraining — (String)

            The managed draining option for the Auto Scaling group capacity provider. When you enable this, Amazon ECS manages and gracefully drains the EC2 container instances that are in the Auto Scaling group capacity provider.

            Possible values include:
            • "ENABLED"
            • "DISABLED"
        • updateStatus — (String)

          The update status of the capacity provider. The following are the possible states that is returned.

          DELETE_IN_PROGRESS

          The capacity provider is in the process of being deleted.

          DELETE_COMPLETE

          The capacity provider was successfully deleted and has an INACTIVE status.

          DELETE_FAILED

          The capacity provider can't be deleted. The update status reason provides further details about why the delete failed.

          Possible values include:
          • "DELETE_IN_PROGRESS"
          • "DELETE_COMPLETE"
          • "DELETE_FAILED"
          • "UPDATE_IN_PROGRESS"
          • "UPDATE_COMPLETE"
          • "UPDATE_FAILED"
        • updateStatusReason — (String)

          The update status reason. This provides further details about the update status for the capacity provider.

        • tags — (Array<map>)

          The metadata that you apply to the capacity provider to help you categorize and organize it. Each tag consists of a key and an optional value. You define both.

          The following basic restrictions apply to tags:

          • Maximum number of tags per resource - 50

          • For each resource, each tag key must be unique, and each tag key can have only one value.

          • Maximum key length - 128 Unicode characters in UTF-8

          • Maximum value length - 256 Unicode characters in UTF-8

          • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

          • Tag keys and values are case-sensitive.

          • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

          • key — (String)

            One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

          • value — (String)

            The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

deleteCluster(params = {}, callback) ⇒ AWS.Request

Deletes the specified cluster. The cluster transitions to the INACTIVE state. Clusters with an INACTIVE status might remain discoverable in your account for a period of time. However, this behavior is subject to change in the future. We don't recommend that you rely on INACTIVE clusters persisting.

You must deregister all container instances from this cluster before you may delete it. You can list the container instances in a cluster with ListContainerInstances and deregister them with DeregisterContainerInstance.

            If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

            An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

          • base — (Integer)

            The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

          • details — (Array<map>)

            Details of the attachment.

            For elastic network interfaces, this includes the network interface ID, the MAC address, the subnet ID, and the private IPv4 address.

            For Service Connect services, this includes portName, clientAliases, discoveryName, and ingressPortOverride.

            For Elastic Block Storage, this includes roleArn, deleteOnTermination, volumeName, volumeId, and statusReason (only when the attachment fails to create or attach).

          UPDATE_COMPLETE

          The capacity providers have successfully updated.

          UPDATE_FAILED

          The capacity provider updates failed.

        • serviceConnectDefaults — (map)

          Use this parameter to set a default Service Connect namespace. After you set a default Service Connect namespace, any new services with Service Connect turned on that are created in the cluster are added as client services in the namespace. This setting only applies to new services that set the enabled parameter to true in the ServiceConnectConfiguration. You can set the namespace of each service individually in the ServiceConnectConfiguration to override this default parameter.

          Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

          • namespace — (String)

            The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace. When you create a service and don't specify a Service Connect configuration, this namespace is used.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

deleteService(params = {}, callback) ⇒ AWS.Request

Deletes a specified service within a cluster. You can delete a service if you have no running tasks in it and the desired task count is zero. If the service is actively maintaining tasks, you can't delete it, and you must update the service to a desired task count of zero. For more information, see UpdateService.

Note: When you delete a service, if there are still running tasks that require cleanup, the service status moves from ACTIVE to DRAINING, and the service is no longer visible in the console or in the ListServices API operation. After all tasks have transitioned to either STOPPING or STOPPED status, the service status moves from DRAINING to INACTIVE. Services in the DRAINING or INACTIVE status can still be viewed with the DescribeServices API operation. However, in the future, INACTIVE services may be cleaned up and purged from Amazon ECS record keeping, and DescribeServices calls on those services return a ServiceNotFoundException error.

If you attempt to create a new service with the same name as an existing service in either ACTIVE or DRAINING status, you receive an error.

Service Reference:

Examples:

To delete a service


/* This example deletes the my-http-service service. The service must have a desired count and running count of 0 before you can delete it. */

 var params = {
  service: "my-http-service"
 };
 ecs.deleteService(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*
   data = {
   }
   */
 });

Calling the deleteService operation

var params = {
  service: 'STRING_VALUE', /* required */
  cluster: 'STRING_VALUE',
  force: true || false
};

            For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

            For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.

            If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance. Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

          • loadBalancerName — (String)

            The name of the load balancer to associate with the Amazon ECS service or task set.

            If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

          • containerName — (String)

            The name of the container (as it appears in a container definition) to associate with the load balancer.

            You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

          • containerPort — (Integer)

            The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

        • serviceRegistries — (Array<map>)

          The details for the service discovery registries to assign to this service. For more information, see Service Discovery.

          • registryArn — (String)

            The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.

          • port — (Integer)

            The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.

          • containerName — (String)

            The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

          • containerPort — (Integer)

            The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

        • status — (String)

          The status of the service. The valid values are ACTIVE, DRAINING, or INACTIVE.

        • desiredCount — (Integer)

          The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService.

        • runningCount — (Integer)

          The number of tasks in the cluster that are in the RUNNING state.

        • pendingCount — (Integer)

          The number of tasks in the cluster that are in the PENDING state.

        • launchType — (String)

          The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.

          Possible values include:
          • "EC2"
          • "FARGATE"
          • "EXTERNAL"
        • capacityProviderStrategy — (Array<map>)

          The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.

          • capacityProviderrequired — (String)

            The short name of the capacity provider.

          • weight — (Integer)

            The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

            If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

            An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

          • base — (Integer)

            The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

        • platformVersion — (String)

          The platform version to run your service on. A platform version is only specified for tasks that are hosted on Fargate. If one isn't specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.

        • platformFamily — (String)

          The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.

          All tasks that run as part of this service must use the same platformFamily value as the service (for example, LINUX).

        • taskDefinition — (String)

          The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.

        • deploymentConfiguration — (map)

          Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.

          • deploymentCircuitBreaker — (map)
            Note: The deployment circuit breaker can only be used for services using the rolling update (ECS) deployment type.

            The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide

            • enablerequired — (Boolean)

              Determines whether to use the deployment circuit breaker logic for the service.

            • rollbackrequired — (Boolean)

              Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

          • maximumPercent — (Integer)

            If a service is using the rolling update (ECS) deployment type, the maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.

            If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.

          • minimumHealthyPercent — (Integer)

            If a service is using the rolling update (ECS) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.

            For services that do not use a load balancer, the following should be noted:

            • A service is considered healthy if all essential containers within the tasks in the service pass their health checks.

            • If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.

            • If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.

            For services that do use a load balancer, the following should be noted:

            • If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

            • If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

            The default value for a replica service for minimumHealthyPercent is 100%. The default minimumHealthyPercent value for a service using the DAEMON service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.

            The minimum number of healthy tasks during a deployment is the desiredCount multiplied by the minimumHealthyPercent/100, rounded up to the nearest integer value.

            If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

          • alarms — (map)

            Information about the CloudWatch alarms.

            • alarmNamesrequired — (Array<String>)

              One or more CloudWatch alarm names. Use a "," to separate the alarms.

            • enablerequired — (Boolean)

              Determines whether to use the CloudWatch alarm option in the service deployment process.

            • rollbackrequired — (Boolean)

              Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is used, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

        • taskSets — (Array<map>)

          Information about a set of Amazon ECS tasks in either an CodeDeploy or an EXTERNAL deployment. An Amazon ECS task set includes details such as the desired number of tasks, how many tasks are running, and whether the task set serves production traffic.

          • startedBy — (String)

            The tag specified when a task set is started. If an CodeDeploy deployment created the task set, the startedBy parameter is CODE_DEPLOY. If an external deployment created the task set, the startedBy field isn't used.

          • externalId — (String)

            The external ID associated with the task set.

            If an CodeDeploy deployment created a task set, the externalId parameter contains the CodeDeploy deployment ID.

            If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute.

          • status — (String)

            The status of the task set. The following describes each state.

            PRIMARY

            The task set is serving production traffic.

            ACTIVE

            The task set isn't serving production traffic.

            DRAINING

            The tasks in the task set are being stopped, and their corresponding targets are being deregistered from their target group.

          • taskDefinition — (String)

            The task definition that the task set is using.

          • computedDesiredCount — (Integer)

            The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.

          • pendingCount — (Integer)

            The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it's restarted after being in the STOPPED state.

          • runningCount — (Integer)

            The number of tasks in the task set that are in the RUNNING status during a deployment. A task in the RUNNING state is running and ready for use.

          • createdAt — (Date)

            The Unix timestamp for the time when the task set was created.

          • updatedAt — (Date)

            The Unix timestamp for the time when the task set was last updated.

          • launchType — (String)

            The launch type the tasks in the task set are using. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

            Possible values include:
            • "EC2"
            • "FARGATE"
            • "EXTERNAL"
          • capacityProviderStrategy — (Array<map>)

            The capacity provider strategy that are associated with the task set.

            • capacityProviderrequired — (String)

              The short name of the capacity provider.

            • weight — (Integer)

              The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

              If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

              An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

            • base — (Integer)

              The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

          • platformVersion — (String)

            The Fargate platform version where the tasks in the task set are running. A platform version is only specified for tasks run on Fargate. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

          • platformFamily — (String)

            The operating system that your tasks in the set are running on. A platform family is specified only for tasks that use the Fargate launch type.

            All tasks in the set must have the same value.

          • networkConfiguration — (map)

              • securityGroups — (Array<String>)

                The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration.

                Note: All specified security groups must be from the same VPC.
              • assignPublicIp — (String)

                Whether the task's elastic network interface receives a public IP address. The default value is DISABLED.

                Possible values include:
                • "ENABLED"
                • "DISABLED"
          • loadBalancers — (Array<map>)

            Details on a load balancer that are used with a task set.

            • targetGroupArn — (String)

              The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

              A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

              For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

              For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.

              If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance. Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

            • loadBalancerName — (String)

              The name of the load balancer to associate with the Amazon ECS service or task set.

              If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

            • containerName — (String)

              The name of the container (as it appears in a container definition) to associate with the load balancer.

              You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

            • containerPort — (Integer)

              The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

          • serviceRegistries — (Array<map>)

            The details for the service discovery registries to assign to this task set. For more information, see Service discovery.

            • containerName — (String)

              The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

            • containerPort — (Integer)

              The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

          • scale — (map)

            A floating-point percentage of your desired number of tasks to place and keep running in the task set.

            • value — (Float)

              The value, specified as a percent total of a service's desiredCount, to scale the task set. Accepted values are numbers between 0 and 100.

            • unit — (String)

              The unit of measure for the scale value.

            • The pendingCount is 0.

            • There are no tasks that are running on container instances in the DRAINING status.

            • All tasks are reporting a healthy status from the load balancers, service discovery, and container health checks.

            If any of those conditions aren't met, the stability status returns STABILIZING.

            Possible values include:
            • "STEADY_STATE"
            • "STABILIZING"
          • stabilityStatusAt — (Date)

            The Unix timestamp for the time when the task set stability status was retrieved.

          • tags — (Array<map>)

            The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value. You define both.

            The following basic restrictions apply to tags:

            • Maximum number of tags per resource - 50

            • For each resource, each tag key must be unique, and each tag key can have only one value.

            • Maximum key length - 128 Unicode characters in UTF-8

            • Maximum value length - 256 Unicode characters in UTF-8

            • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

            • Tag keys and values are case-sensitive.

            • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

            • key — (String)

              One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

            • value — (String)

              The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

            PRIMARY

            The most recent deployment of a service.

            ACTIVE

            A service deployment that still has running tasks, but are in the process of being replaced with a new PRIMARY deployment.

            INACTIVE

            A deployment that has been completely replaced.

          • taskDefinition — (String)

            The most recent task definition that was specified for the tasks in the service to use.

          • desiredCount — (Integer)

            The most recent desired count of tasks that was specified for the service to deploy or maintain.

          • pendingCount — (Integer)

            The number of tasks in the deployment that are in the PENDING status.

          • runningCount — (Integer)

            The number of tasks in the deployment that are in the RUNNING status.

          • failedTasks — (Integer)

            The number of consecutively failed tasks in the deployment. A task is considered a failure if the service scheduler can't launch the task, the task doesn't transition to a RUNNING state, or if it fails any of its defined health checks and is stopped.

            Note: Once a service deployment has one or more successfully running tasks, the failed task count resets to zero and stops being evaluated.
          • createdAt — (Date)

            The Unix timestamp for the time when the service deployment was created.

          • updatedAt — (Date)

            The Unix timestamp for the time when the service deployment was last updated.

          • capacityProviderStrategy — (Array<map>)

            The capacity provider strategy that the deployment is using.

            • capacityProviderrequired — (String)

              The short name of the capacity provider.

            • weight — (Integer)

              The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

              If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

              An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

            • base — (Integer)

              The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

          • launchType — (String)

            The launch type the tasks in the service are using. For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide.

            • "EXTERNAL"
          • platformVersion — (String)

            The platform version that your tasks in the service run on. A platform version is only specified for tasks using the Fargate launch type. If one isn't specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.

          • platformFamily — (String)

            The operating system that your tasks in the service, or tasks are running on. A platform family is specified only for tasks using the Fargate launch type.

            All tasks that run as part of this service must use the same platformFamily value as the service, for example, LINUX..

          • networkConfiguration — (map)

              • securityGroups — (Array<String>)

                The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration.

                Note: All specified security groups must be from the same VPC.
              • assignPublicIp — (String)

                Whether the task's elastic network interface receives a public IP address. The default value is DISABLED.

                Possible values include:

            The rollout state of the deployment. When a service deployment is started, it begins in an IN_PROGRESS state. When the service reaches a steady state, the deployment transitions to a COMPLETED state. If the service fails to reach a steady state and circuit breaker is turned on, the deployment transitions to a FAILED state. A deployment in FAILED state doesn't launch any new tasks. For more information, see DeploymentCircuitBreaker.

            Possible values include:
            • "COMPLETED"
            • "FAILED"
            • "IN_PROGRESS"

            The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.

            Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

            • enabledrequired — (Boolean)

              Specifies whether to use Service Connect with this service.

            • namespace — (String)

              The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace for use with Service Connect. The namespace must be in the same Amazon Web Services Region as the Amazon ECS service and cluster. The type of namespace doesn't affect Service Connect. For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide.

            • services — (Array<map>)

              The list of Service Connect service objects. These are names and aliases (also known as endpoints) that are used by other Amazon ECS services to connect to this service.

              This field is not required for a "client" Amazon ECS service that's a member of a namespace only to connect to other services within the namespace. An example of this would be a frontend application that accepts incoming requests from either a load balancer that's attached to the service or by other means.

              An object selects a port from the task definition, assigns a name for the Cloud Map service, and a list of aliases (endpoints) and ports for client applications to refer to this service.

              • portNamerequired — (String)

                The portName must match the name of one of the portMappings from all the containers in the task definition of this Amazon ECS service.

              • discoveryName — (String)

                The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

                If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

              • clientAliases — (Array<map>)

                The list of client aliases for this Service Connect service. You use these to assign names that can be used by client applications. The maximum number of client aliases that you can have in this list is 1.

                Each alias ("endpoint") is a fully-qualified name and port number that other Amazon ECS tasks ("clients") can use to connect to this service.

                Each name and port mapping must be unique within the namespace.

                For each ServiceConnectService, you must provide at least one clientAlias with one port.

                • portrequired — (Integer)

                  The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.

                  To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

                • dnsName — (String)

                  The dnsName is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.

                  If this parameter isn't specified, the default value of discoveryName.namespace is used. If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

                  To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are database, db, or the lowercase name of a database, such as mysql or redis. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

              • ingressPortOverride — (Integer)

                The port number for the Service Connect proxy to listen on.

                Use the value of this field to bypass the proxy for traffic on the port number specified in the named portMapping in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.

                In awsvpc mode and Fargate, the default value is the container port number. The container port number is in the portMapping in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.

              • timeout — (map)

                A reference to an object that represents the configured timeouts for Service Connect.

                • idleTimeoutSeconds — (Integer)

                  The amount of time in seconds a connection will stay active while idle. A value of 0 can be set to disable idleTimeout.

                  The idleTimeout default for HTTP/HTTP2/GRPC is 5 minutes.

                  The idleTimeout default for TCP is 1 hour.

                • perRequestTimeoutSeconds — (Integer)

                  The amount of time waiting for the upstream to respond with a complete response per request. A value of 0 can be set to disable perRequestTimeout. perRequestTimeout can only be set if Service Connect appProtocol isn't TCP. Only idleTimeout is allowed for TCP appProtocol.

              • tls — (map)

                A reference to an object that represents a Transport Layer Security (TLS) configuration.

                • issuerCertificateAuthorityrequired — (map)

            • logConfiguration — (map)

              The log configuration for the container. This parameter maps to LogConfig in the docker conainer create command and the --log-driver option to docker run.

              By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition.

              Understand the following when specifying a log configuration for your containers.

              • Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent.

                For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

                For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald,syslog, splunk, and awsfirelens.

              • This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.

              • For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide.

              • For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

              • logDriverrequired — (String)

                The log driver to use for the container.

                For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

                For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, syslog, splunk, and awsfirelens.

                For more information about using the awslogs log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.

                For more information about using the awsfirelens log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.

                Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
                Possible values include:
                • "json-file"
                • "syslog"
                • "journald"
                • "gelf"
                • "fluentd"
                • "awslogs"
                • "splunk"
                • "awsfirelens"
              • options — (map<String>)

                The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

              • secretOptions — (Array<map>)

                The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide.

                  The name of the secret.

                • valueFromrequired — (String)

                  The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.

                  For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide.

                  Note: If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
          • serviceConnectResources — (Array<map>)

            The list of Service Connect resources that are associated with this deployment. Each list entry maps a discovery name to a Cloud Map service name.

              The discovery name of this Service Connect resource.

              The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

              If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

            • discoveryArn — (String)

              The Amazon Resource Name (ARN) for the namespace in Cloud Map that matches the discovery name for this Service Connect resource. You can use this ARN in other integrations with Cloud Map. However, Service Connect can't ensure connectivity outside of Amazon ECS.

          • volumeConfigurations — (Array<map>)

            The details of the volume that was configuredAtLaunch. You can configure different settings like the size, throughput, volumeType, and ecryption in ServiceManagedEBSVolumeConfiguration. The name of the volume must match the name from the task definition.

            • namerequired — (String)

              The name of the volume. This value must match the volume name from the Volume object in the task definition.

            • managedEBSVolume — (map)

              The configuration for the Amazon EBS volume that Amazon ECS creates and manages on your behalf. These settings are used to create each Amazon EBS volume, with one volume created for each task in the service. The Amazon EBS volumes are visible in your account in the Amazon EC2 console once they are created.

              • encrypted — (Boolean)

                Indicates whether the volume should be encrypted. If no value is specified, encryption is turned on by default. This parameter maps 1:1 with the Encrypted parameter of the CreateVolume API in the Amazon EC2 API Reference.

              • kmsKeyId — (String)

                The Amazon Resource Name (ARN) identifier of the Amazon Web Services Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no Amazon Web Services Key Management Service key is specified, the default Amazon Web Services managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the KmsKeyId parameter of the CreateVolume API in the Amazon EC2 API Reference.

                Amazon Web Services authenticates the Amazon Web Services Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails.

              • volumeType — (String)

                The volume type. This parameter maps 1:1 with the VolumeType parameter of the CreateVolume API in the Amazon EC2 API Reference. For more information, see Amazon EBS volume types in the Amazon EC2 User Guide.

                The following are the supported volume types.

                • General Purpose SSD: gp2|gp3

                • Provisioned IOPS SSD: io1|io2

              • sizeInGiB — (Integer)

                The size of the volume in GiB. You must specify either a volume size or a snapshot ID. If you specify a snapshot ID, the snapshot size is used for the volume size by default. You can optionally specify a volume size greater than or equal to the snapshot size. This parameter maps 1:1 with the Size parameter of the CreateVolume API in the Amazon EC2 API Reference.

                The following are the supported volume size values for each volume type.

                • gp2 and gp3: 1-16,384

                • io1 and io2: 4-16,384

                • st1 and sc1: 125-16,384

              • snapshotId — (String)

                The snapshot that Amazon ECS uses to create the volume. You must specify either a snapshot ID or a volume size. This parameter maps 1:1 with the SnapshotId parameter of the CreateVolume API in the Amazon EC2 API Reference.

              • iops — (Integer)

                The number of I/O operations per second (IOPS). For gp3, io1, and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.

                The following are the supported values for each volume type.

                • gp3: 3,000 - 16,000 IOPS

                • io1: 100 - 64,000 IOPS

                • io2: 100 - 256,000 IOPS

                This parameter is required for io1 and io2 volume types. The default for gp3 volumes is 3,000 IOPS. This parameter is not supported for st1, sc1, or standard volume types.

                This parameter maps 1:1 with the Iops parameter of the CreateVolume API in the Amazon EC2 API Reference.

              • throughput — (Integer)

                The throughput to provision for a volume, in MiB/s, with a maximum of 1,000 MiB/s. This parameter maps 1:1 with the Throughput parameter of the CreateVolume API in the Amazon EC2 API Reference.

                This parameter is only supported for the gp3 volume type.

              • tagSpecifications — (Array<map>)

              • roleArnrequired — (String)

                The ARN of the IAM role to associate with this volume. This is the Amazon ECS infrastructure IAM role that is used to manage your Amazon Web Services infrastructure. We recommend using the Amazon ECS-managed AmazonECSInfrastructureRolePolicyForVolumes IAM policy with this role. For more information, see Amazon ECS infrastructure IAM role in the Amazon ECS Developer Guide.

              • filesystemType — (String)

                The Linux filesystem type for the volume. For volumes created from a snapshot, you must specify the same filesystem type that the volume was using when the snapshot was created. If there is a filesystem type mismatch, the task will fail to start.

                The available filesystem types are
 ext3, ext4, and xfs. If no value is specified, the xfs filesystem type is used by default.

                Possible values include:
                • "ext3"
                • "ext4"
                • "xfs"
          • fargateEphemeralStorage — (map)

            The Fargate ephemeral storage settings for the deployment.

            • kmsKeyId — (String)

              Specify an Key Management Service key ID to encrypt the ephemeral storage for deployment.

        • roleArn — (String)

        • events — (Array<map>)

          The event stream for your service. A maximum of 100 of the latest events are displayed.

          • id — (String)

            The ID string for the event.

          • createdAt — (Date)

            The Unix timestamp for the time when the event was triggered.

          • message — (String)

            The event message.

        • createdAt — (Date)

          The Unix timestamp for the time when the service was created.

        • placementConstraints — (Array<map>)

          The placement constraints for the tasks in the service.

          • type — (String)

            The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.

            Possible values include:
            • "distinctInstance"
            • "memberOf"
          • expression — (String)

            A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is distinctInstance. For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide.

        • placementStrategy — (Array<map>)

          The placement strategy that determines how tasks for the service are placed.

          • type — (String)

            The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that's specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.

            Possible values include:
            • "random"
            • "spread"
            • "binpack"
          • field — (String)

            The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host, which has the same effect), or any platform or custom attribute that's applied to a container instance, such as attribute:ecs.availability-zone. For the binpack placement strategy, valid values are cpu and memory. For the random placement strategy, this field is not used.

        • networkConfiguration — (map)

          The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.

          • awsvpcConfiguration — (map)

            The VPC subnets and security groups that are associated with a task.

            Note: All specified subnets and security groups must be from the same VPC.
            • subnetsrequired — (Array<String>)

              The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per awsvpcConfiguration.

              Note: All specified subnets must be from the same VPC.
            • securityGroups — (Array<String>)

              The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration.

              Note: All specified security groups must be from the same VPC.
            • assignPublicIp — (String)

              Whether the task's elastic network interface receives a public IP address. The default value is DISABLED.

              Possible values include:
              • "ENABLED"
              • "DISABLED"
        • healthCheckGracePeriodSeconds — (Integer)

          The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started.

        • schedulingStrategy — (String)

          The scheduling strategy to use for the service. For more information, see Services.

          There are two service scheduler strategies available.

          • REPLICA-The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions.

          • DAEMON-The daemon scheduling strategy deploys exactly one task on each active container instance. This task meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It stop tasks that don't meet the placement constraints.

            Note: Fargate tasks don't support the DAEMON scheduling strategy.
          Possible values include:
          • "REPLICA"
          • "DAEMON"
        • deploymentController — (map)

          The deployment controller type the service is using.

          • typerequired — (String)

            The deployment controller type to use.

            There are three deployment controller types available:

            ECS

            The rolling update (ECS) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration.

            CODE_DEPLOY

            The blue/green (CODE_DEPLOY) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.

            EXTERNAL

            The external (EXTERNAL) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.

            Possible values include:
            • "ECS"
            • "CODE_DEPLOY"
            • "EXTERNAL"
        • tags — (Array<map>)

          The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value. You define bot the key and value.

          The following basic restrictions apply to tags:

          • Maximum number of tags per resource - 50

          • For each resource, each tag key must be unique, and each tag key can have only one value.

          • Maximum key length - 128 Unicode characters in UTF-8

          • Maximum value length - 256 Unicode characters in UTF-8

          • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

          • Tag keys and values are case-sensitive.

          • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

          • key — (String)

            One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

          • value — (String)

            The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

        • createdBy — (String)

          The principal that created the service.

        • enableECSManagedTags — (Boolean)

          Determines whether to use Amazon ECS managed tags for the tasks in the service. For more information, see Tagging Your Amazon ECS Resources in the Amazon Elastic Container Service Developer Guide.

        • propagateTags — (String)

          Determines whether to propagate the tags from the task definition or the service to the task. If no value is specified, the tags aren't propagated.

          Possible values include:
          • "TASK_DEFINITION"
          • "SERVICE"
          • "NONE"
        • enableExecuteCommand — (Boolean)

          Determines whether the execute command functionality is turned on for the service. If true, the execute command functionality is turned on for all containers in tasks as part of the service.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

deleteTaskDefinitions(params = {}, callback) ⇒ AWS.Request

Deletes one or more task definitions.

You must deregister a task definition revision before you delete it. For more information, see DeregisterTaskDefinition.

When you delete a task definition revision, it is immediately transitions from the INACTIVE to DELETE_IN_PROGRESS. Existing tasks and services that reference a DELETE_IN_PROGRESS task definition revision continue to run without disruption. Existing services that reference a DELETE_IN_PROGRESS task definition revision can still scale up or down by modifying the service's desired count.

You can't use a DELETE_IN_PROGRESS task definition revision to run new tasks or create new services. You also can't update an existing service to reference a DELETE_IN_PROGRESS task definition revision.

A task definition revision will stay in DELETE_IN_PROGRESS status until all the associated tasks and services have been terminated.

When you delete all INACTIVE task definition revisions, the task definition name is not displayed in the console and not returned in the API. If a task definition revisions are in the DELETE_IN_PROGRESS state, the task definition name is displayed in the console and returned in the API. The task definition name is retained by Amazon ECS and the revision is incremented the next time you create a task definition with that name.

Service Reference:

Examples:

Calling the deleteTaskDefinitions operation

var params = {
  taskDefinitions: [ /* required */
    'STRING_VALUE',
    /* more items */
  ]
};
ecs.deleteTaskDefinitions(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • taskDefinitions — (Array<String>)

      The family and revision (family:revision) or full Amazon Resource Name (ARN) of the task definition to delete. You must specify a revision.

      You can specify up to 10 task definitions as a comma separated list.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • taskDefinitions — (Array<map>)

        The list of deleted task definitions.

        • taskDefinitionArn — (String)

          The full Amazon Resource Name (ARN) of the task definition.

        • containerDefinitions — (Array<map>)

          A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.

          • name — (String)

            The name of a container. If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in tthe docker conainer create command and the --name option to docker run.

          • image — (String)

            The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the docker conainer create command and the IMAGE parameter of docker run.

            • When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.

            • Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag or registry/repository@digest. For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE.

            • Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo).

            • Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent).

            • Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu).

          • repositoryCredentials — (map)

            The private repository authentication credentials to use.

            • credentialsParameterrequired — (String)

              The Amazon Resource Name (ARN) of the secret containing the private repository credentials.

              Note: When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
          • cpu — (Integer)

            The number of cpu units reserved for the container. This parameter maps to CpuShares in the docker conainer create commandand the --cpu-shares option to docker run.

            This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.

            Note: You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.

            Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.

            On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. The minimum valid CPU share value that the Linux kernel allows is 2, and the maximum valid CPU share value that the Linux kernel allows is 262144. However, the CPU parameter isn't required, and you can use CPU values below 2 or above 262144 in your container definitions. For CPU values below 2 (including null) or above 262144, the behavior varies based on your Amazon ECS container agent version:

            • Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.

            • Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.

            • Agent versions greater than or equal to 1.84.0: CPU values greater than 256 vCPU are passed to Docker as 256, which is equivalent to 262144 CPU shares.

            On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0, which Windows interprets as 1% of one CPU.

          • memory — (Integer)

            The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in thethe docker conainer create command and the --memory option to docker run.

            If using the Fargate launch type, this parameter is optional.

            If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.

            The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.

            The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.

          • memoryReservation — (Integer)

            The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the the docker conainer create command and the --memory-reservation option to docker run.

            If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.

            For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.

            The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.

            The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.

          • links — (Array<String>)

            The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge. The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.. This parameter maps to Links in the docker conainer create command and the --link option to docker run.

            Note: This parameter is not supported for Windows containers.

            Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.

          • portMappings — (Array<map>)

            The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.

            For task definitions that use the awsvpc network mode, only specify the containerPort. The hostPort can be left blank or it must be the same value as the containerPort.

            Port mappings on Windows use the NetNAT gateway address rather than localhost. There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.

            This parameter maps to PortBindings in the the docker conainer create command and the --publish option to docker run. If the network mode of a task definition is set to none, then you can't specify port mappings. If the network mode of a task definition is set to host, then host ports must either be undefined or they must match the container port in the port mapping.

            Note: After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.
            • containerPort — (Integer)

              The port number on the container that's bound to the user-specified or automatically assigned host port.

              If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort.

              If you use containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort. Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.

            • hostPort — (Integer)

              The port number on the container instance to reserve for your container.

              If you specify a containerPortRange, leave this field empty and the value of the hostPort is set as follows:

              • For containers in a task with the awsvpc network mode, the hostPort is set to the same value as the containerPort. This is a static mapping strategy.

              • For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.

              If you use containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort.

              If you use containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.

              The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.

              The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.

            • protocol — (String)

              The protocol used for the port mapping. Valid values are tcp and udp. The default is tcp. protocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.

              Possible values include:
              • "tcp"
              • "udp"
            • name — (String)

              The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the serviceConnectConfiguration of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

              For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

            • appProtocol — (String)

              The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.

              If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.

              appProtocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.

              Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

              Possible values include:
              • "http"
              • "http2"
              • "grpc"
            • containerPortRange — (String)

              The port number range on the container that's bound to the dynamically mapped host port range.

              The following rules apply when you specify a containerPortRange:

              • You must use either the bridge network mode or the awsvpc network mode.

              • This parameter is available for both the EC2 and Fargate launch types.

              • This parameter is available for both the Linux and Windows operating systems.

              • The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package

              • You can specify a maximum of 100 port ranges per container.

              • You do not specify a hostPortRange. The value of the hostPortRange is set as follows:

                • For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange. This is a static mapping strategy.

                • For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.

              • The containerPortRange valid values are between 1 and 65535.

              • A port can only be included in one port mapping per container.

              • You cannot specify overlapping port ranges.

              • The first port in the range must be less than last port in the range.

              • Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.

                For more information, see Issue #11185 on the Github website.

                For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.

              You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.

          • essential — (Boolean)

            If the essential parameter of a container is marked as true, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.

            All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.

          • restartPolicy — (map)

            The restart policy for a container. When you set up a restart policy, Amazon ECS can restart the container without needing to replace the task. For more information, see Restart individual containers in Amazon ECS tasks with container restart policies in the Amazon Elastic Container Service Developer Guide.

            • enabledrequired — (Boolean)

              Specifies whether a restart policy is enabled for the container.

            • ignoredExitCodes — (Array<Integer>)

              A list of exit codes that Amazon ECS will ignore and not attempt a restart on. You can specify a maximum of 50 container exit codes. By default, Amazon ECS does not ignore any exit codes.

            • restartAttemptPeriod — (Integer)

              A period of time (in seconds) that the container must run for before a restart can be attempted. A container can be restarted only once every restartAttemptPeriod seconds. If a container isn't able to run for this time period and exits early, it will not be restarted. You can set a minimum restartAttemptPeriod of 60 seconds and a maximum restartAttemptPeriod of 1800 seconds. By default, a container must run for 300 seconds before it can be restarted.

          • entryPoint — (Array<String>)

            Early versions of the Amazon ECS container agent don't properly handle entryPoint parameters. If you have problems using entryPoint, update your container agent or enter your commands and arguments as command array items instead.

            The entry point that's passed to the container. This parameter maps to Entrypoint in tthe docker conainer create command and the --entrypoint option to docker run.

          • command — (Array<String>)

            The command that's passed to the container. This parameter maps to Cmd in the docker conainer create command and the COMMAND parameter to docker run. If there are multiple arguments, each argument is a separated string in the array.

          • environment — (Array<map>)

            The environment variables to pass to a container. This parameter maps to Env in the docker conainer create command and the --env option to docker run.

            We don't recommend that you use plaintext environment variables for sensitive information, such as credential data.

            • name — (String)

              The name of the key-value pair. For environment variables, this is the name of the environment variable.

            • value — (String)

              The value of the key-value pair. For environment variables, this is the value of the environment variable.

          • environmentFiles — (Array<map>)

            A list of files containing the environment variables to pass to a container. This parameter maps to the --env-file option to docker run.

            You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file contains an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored.

            If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide.

            • valuerequired — (String)

              The Amazon Resource Name (ARN) of the Amazon S3 object containing the environment variable file.

            • typerequired — (String)

          • mountPoints — (Array<map>)

            The mount points for data volumes in your container.

            This parameter maps to Volumes in the the docker conainer create command and the --volume option to docker run.

            Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives.

            • sourceVolume — (String)

              The name of the volume to mount. Must be a volume name referenced in the name parameter of task definition volume.

            • containerPath — (String)

            • readOnly — (Boolean)

              If this value is true, the container has read-only access to the volume. If this value is false, then the container can write to the volume. The default value is false.

          • volumesFrom — (Array<map>)

            Data volumes to mount from another container. This parameter maps to VolumesFrom in tthe docker conainer create command and the --volumes-from option to docker run.

          • linuxParameters — (map)

            Linux-specific modifications that are applied to the container, such as Linux kernel capabilities. For more information see KernelCapabilities.

            Note: This parameter is not supported for Windows containers.
            • capabilities — (map)

              The Linux capabilities for the container that are added to or dropped from the default configuration provided by Docker.

              • add — (Array<String>)

                The Linux capabilities for the container that have been added to the default configuration provided by Docker. This parameter maps to CapAdd in the docker conainer create command and the --cap-add option to docker run.

                Note: Tasks launched on Fargate only support adding the SYS_PTRACE kernel capability.

                Valid values: "ALL" | "AUDIT_CONTROL" | "AUDIT_WRITE" | "BLOCK_SUSPEND" | "CHOWN" | "DAC_OVERRIDE" | "DAC_READ_SEARCH" | "FOWNER" | "FSETID" | "IPC_LOCK" | "IPC_OWNER" | "KILL" | "LEASE" | "LINUX_IMMUTABLE" | "MAC_ADMIN" | "MAC_OVERRIDE" | "MKNOD" | "NET_ADMIN" | "NET_BIND_SERVICE" | "NET_BROADCAST" | "NET_RAW" | "SETFCAP" | "SETGID" | "SETPCAP" | "SETUID" | "SYS_ADMIN" | "SYS_BOOT" | "SYS_CHROOT" | "SYS_MODULE" | "SYS_NICE" | "SYS_PACCT" | "SYS_PTRACE" | "SYS_RAWIO" | "SYS_RESOURCE" | "SYS_TIME" | "SYS_TTY_CONFIG" | "SYSLOG" | "WAKE_ALARM"

              • drop — (Array<String>)

            • devices — (Array<map>)

              Any host devices to expose to the container. This parameter maps to Devices in tthe docker conainer create command and the --device option to docker run.

              Note: If you're using tasks that use the Fargate launch type, the devices parameter isn't supported.
              • hostPathrequired — (String)

                The path for the device on the host container instance.

              • containerPath — (String)

            • initProcessEnabled — (Boolean)

              Run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

            • sharedMemorySize — (Integer)

              The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run.

              Note: If you are using tasks that use the Fargate launch type, the sharedMemorySize parameter is not supported.
            • tmpfs — (Array<map>)

              The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run.

              Note: If you're using tasks that use the Fargate launch type, the tmpfs parameter isn't supported.
              • containerPathrequired — (String)

                The absolute file path where the tmpfs volume is to be mounted.

            • maxSwap — (Integer)

              The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value.

              If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.

              Note: If you're using tasks that use the Fargate launch type, the maxSwap parameter isn't supported. If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.
            • swappiness — (Integer)

              This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100. If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run.

              Note: If you're using tasks that use the Fargate launch type, the swappiness parameter isn't supported. If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.
          • secrets — (Array<map>)

              The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.

              For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide.

              Note: If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
          • dependsOn — (Array<map>)

            The dependencies defined for container startup and shutdown. A container can contain multiple dependencies on other containers in a task definition. When a dependency is defined for container startup, for container shutdown it is reversed.

            For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

            For tasks using the Fargate launch type, the task or service requires the following platforms:

            • Linux platform version 1.3.0 or later.

            • Windows platform version 1.0.0 or later.

            • containerNamerequired — (String)

              The name of a container.

            • conditionrequired — (String)

              The dependency condition of the container. The following are the available conditions and their behavior:

              • START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.

              • COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.

              • SUCCESS - This condition is the same as COMPLETE, but it also requires that the container exits with a zero status. This condition can't be set on an essential container.

              • HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.

              Possible values include:
              • "START"
              • "COMPLETE"
              • "SUCCESS"
              • "HEALTHY"
          • startTimeout — (Integer)

            Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE, SUCCESS, or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state.

            Note: When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it's enforced independently from this start timeout value.

            For tasks using the Fargate launch type, the task or service requires the following platforms:

            • Linux platform version 1.3.0 or later.

            • Windows platform version 1.0.0 or later.

            For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

            The valid values for Fargate are 2-120 seconds.

          • stopTimeout — (Integer)

            Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.

            For tasks using the Fargate launch type, the task or service requires the following platforms:

            • Linux platform version 1.3.0 or later.

            • Windows platform version 1.0.0 or later.

            The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.

            For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

            The valid values are 2-120 seconds.

          • hostname — (String)

            The hostname to use for your container. This parameter maps to Hostname in thethe docker conainer create command and the --hostname option to docker run.

          • user — (String)

            The user to use inside the container. This parameter maps to User in the docker conainer create command and the --user option to docker run.

            When running tasks using the host network mode, don't run containers using the root user (UID 0). We recommend using a non-root user for better security.

            You can specify the user using the following formats. If specifying a UID or GID, you must specify it as a positive integer.

            • user

            • user:group

            • uid

            • uid:gid

            • user:gid

            When this parameter is true, networking is off within the container. This parameter maps to NetworkDisabled in the docker conainer create command.

            Note: This parameter is not supported for Windows containers.
          • privileged — (Boolean)

            When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root user). This parameter maps to Privileged in the the docker conainer create command and the --privileged option to docker run

            Note: This parameter is not supported for Windows containers or tasks run on Fargate.

            Note: This parameter is not supported for Windows containers.
          • extraHosts — (Array<map>)

            A list of hostnames and IP address mappings to append to the /etc/hosts file on the container. This parameter maps to ExtraHosts in the docker conainer create command and the --add-host option to docker run.

            Note: This parameter isn't supported for Windows containers or tasks that use the awsvpc network mode.
            • hostnamerequired — (String)

              The hostname to use in the /etc/hosts entry.

            • ipAddressrequired — (String)

          • dockerSecurityOptions — (Array<String>)

            A list of strings to provide custom configuration for multiple security systems. This field isn't valid for containers in tasks using the Fargate launch type.

            For Linux tasks on EC2, this parameter can be used to reference custom labels for SELinux and AppArmor multi-level security systems.

            For any tasks on EC2, this parameter can be used to reference a credential spec file that configures a container for Active Directory authentication. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers in the Amazon Elastic Container Service Developer Guide.

            This parameter maps to SecurityOpt in the docker conainer create command and the --security-opt option to docker run.

            Note: The Amazon ECS container agent running on a container instance must register with the ECS_SELINUX_CAPABLE=true or ECS_APPARMOR_CAPABLE=true environment variables before containers placed on that instance can use these security options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.

            Valid values: "no-new-privileges" | "apparmor:PROFILE" | "label:value" | "credentialspec:CredentialSpecFilePath"

          • interactive — (Boolean)

            When this parameter is true, you can deploy containerized applications that require stdin or a tty to be allocated. This parameter maps to OpenStdin in the docker conainer create command and the --interactive option to docker run.

          • pseudoTerminal — (Boolean)

            When this parameter is true, a TTY is allocated. This parameter maps to Tty in tthe docker conainer create command and the --tty option to docker run.

          • dockerLabels — (map<String>)

            A key/value map of labels to add to the container. This parameter maps to Labels in the docker conainer create command and the --label option to docker run. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

          • ulimits — (Array<map>)

            A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it overrides the default values set by Docker. This parameter maps to Ulimits in tthe docker conainer create command and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type.

            Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 65535 and the default hard limit is 65535.

            This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

            Note: This parameter is not supported for Windows containers.
            • namerequired — (String)

              The type of the ulimit.

              Possible values include:
              • "core"
              • "cpu"
              • "data"
              • "fsize"
              • "locks"
              • "memlock"
              • "msgqueue"

              • "rttime"
              • "sigpending"
              • "stack"
            • softLimitrequired — (Integer)

              The soft limit for the ulimit type.

            • hardLimitrequired — (Integer)

              The hard limit for the ulimit type.

          • logConfiguration — (map)

            The log configuration specification for the container.

            This parameter maps to LogConfig in the docker conainer create command and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options).

            Note: Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.

            This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

            Note: The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.
            • logDriverrequired — (String)

              The log driver to use for the container.

              For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

              For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, syslog, splunk, and awsfirelens.

              For more information about using the awslogs log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.

              For more information about using the awsfirelens log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.

              Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
              Possible values include:
              • "json-file"
              • "syslog"
              • "journald"
              • "gelf"
              • "fluentd"
              • "awslogs"
              • "splunk"
              • "awsfirelens"
            • options — (map<String>)

              The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

            • secretOptions — (Array<map>)

              The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide.

              • namerequired — (String)

                The name of the secret.

              • valueFromrequired — (String)

                The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.

                For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide.

                Note: If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
          • healthCheck — (map)

            The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the docker conainer create command and the HEALTHCHECK parameter of docker run.

            • commandrequired — (Array<String>)

              A string array representing the command that the container runs to determine if it is healthy. The string array must start with CMD to run the command arguments directly, or CMD-SHELL to run the command with the container's default shell.

              When you use the Amazon Web Services Management Console JSON panel, the Command Line Interface, or the APIs, enclose the list of commands in double quotes and brackets.

              [ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]

              You don't include the double quotes and brackets when you use the Amazon Web Services Management Console.

              CMD-SHELL, curl -f http://localhost/ || exit 1

              An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in tthe docker conainer create command

            • interval — (Integer)

              The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.

            • timeout — (Integer)

              The time period in seconds to wait for a health check to succeed before it is considered a failure. You may specify between 2 and 60 seconds. The default value is 5.

            • retries — (Integer)

              The number of times to retry a failed health check before the container is considered unhealthy. You may specify between 1 and 10 retries. The default value is 3.

            • startPeriod — (Integer)

              The optional grace period to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You can specify between 0 and 300 seconds. By default, the startPeriod is off.

              Note: If a health check succeeds within the startPeriod, then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
          • systemControls — (Array<map>)

            A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in tthe docker conainer create command and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.

            • namespace — (String)

              The namespaced kernel parameter to set a value for.

            • value — (String)

              The namespaced kernel parameter to set a value for.

              Valid IPC namespace values: "kernel.msgmax" | "kernel.msgmnb" | "kernel.msgmni" | "kernel.sem" | "kernel.shmall" | "kernel.shmmax" | "kernel.shmmni" | "kernel.shm_rmid_forced", and Sysctls that start with "fs.mqueue.*"

              Valid network namespace values: Sysctls that start with "net.*"

              All of these values are supported by Fargate.

          • resourceRequirements — (Array<map>)

            The type and amount of a resource to assign to a container. The only supported resource is a GPU.

            • valuerequired — (String)

              The value for the specified resource type.

              When the type is GPU, the value is the number of physical GPUs the Amazon ECS container agent reserves for the container. The number of GPUs that's reserved for all containers in a task can't exceed the number of available GPUs on the container instance that the task is launched on.

              When the type is InferenceAccelerator, the value matches the deviceName for an InferenceAccelerator specified in a task definition.

            • typerequired — (String)

              The type of resource to assign to a container.

              Possible values include:
              • "GPU"
              • "InferenceAccelerator"
          • firelensConfiguration — (map)

            The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide.

            • typerequired — (String)

              The log router to use. The valid values are fluentd or fluentbit.

              Possible values include:
              • "fluentd"
              • "fluentbit"
            • options — (map<String>)

              The options to use when configuring the log router. This field is optional and can be used to specify a custom configuration file or to add additional metadata, such as the task, task definition, cluster, and container instance details to the log event. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"}. For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide.

              Note: Tasks hosted on Fargate only support the file configuration file type.
          • credentialSpecs — (Array<String>)

            A list of ARNs in SSM or Amazon S3 to a credential spec (CredSpec) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of the dockerSecurityOptions. The maximum number of ARNs is 1.

            There are two formats for each ARN.

            credentialspecdomainless:MyARN

            You use credentialspecdomainless:MyARN to provide a CredSpec with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.

            Each task that runs on any container instance can join different domains.

            You can use this format without joining the container instance to a domain.

            credentialspec:MyARN

            You use credentialspec:MyARN to provide a CredSpec for a single domain.

            You must join the container instance to the domain before you start any tasks that use this task definition.

            In both formats, replace MyARN with the ARN in SSM or Amazon S3.

            If you provide a credentialspecdomainless:MyARN, the credspec must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.

        • family — (String)

          The name of a family that this task definition is registered to. Up to 255 characters are allowed. Letters (both uppercase and lowercase letters), numbers, hyphens (-), and underscores (_) are allowed.

          A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.

        • taskRoleArn — (String)

          The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

        • executionRoleArn — (String)

          The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

        • networkMode — (String)

          The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. If no network mode is specified, the default is bridge.

          For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.

          With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.

          When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.

          If the network mode is awsvpc, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

          If the network mode is host, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.

          Possible values include:
          • "bridge"
          • "host"
          • "awsvpc"
          • "none"
        • revision — (Integer)

          The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is 1. Each time that you register a new revision of a task definition in the same family, the revision value always increases by one. This is even if you deregistered previous revisions in this family.

        • volumes — (Array<map>)

          The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide.

          Note: The host and sourcePath parameters aren't supported for tasks run on Fargate.
          • name — (String)

            The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.

            When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task.

            For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition.

            When a volume is using the efsVolumeConfiguration, the name is required.

          • host — (map)

            This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.

            Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D::D:\, but not D:\my\path:C:\my\path or D::C:\my\path.

            • sourcePath — (String)

              When the host parameter is used, specify a sourcePath to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.

              If you're using the Fargate launch type, the sourcePath parameter is not supported.

          • dockerVolumeConfiguration — (map)

            This parameter is specified when you use Docker volumes.

            Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.

            Note: Docker volumes aren't supported by tasks run on Fargate.
            • scope — (String)

              The scope for the Docker volume that determines its lifecycle. Docker volumes that are scoped to a task are automatically provisioned when the task starts and destroyed when the task stops. Docker volumes that are scoped as shared persist after the task stops.

              Possible values include:
              • "task"
              • "shared"
            • autoprovision — (Boolean)

              If this value is true, the Docker volume is created if it doesn't already exist.

              Note: This field is only used if the scope is shared.
            • driver — (String)

              The Docker volume driver to use. The driver value must match the driver name provided by Docker because it is used for task placement. If the driver was installed using the Docker plugin CLI, use docker plugin ls to retrieve the driver name from your container instance. If the driver was installed using another method, use Docker plugin discovery to retrieve the driver name. This parameter maps to Driver in the docker conainer create command and the xxdriver option to docker volume create.

            • driverOpts — (map<String>)

              A map of Docker driver-specific options passed through. This parameter maps to DriverOpts in the docker create-volume command and the xxopt option to docker volume create.

            • labels — (map<String>)

              Custom metadata to add to your Docker volume. This parameter maps to Labels in the docker conainer create command and the xxlabel option to docker volume create.

          • efsVolumeConfiguration — (map)

            This parameter is specified when you use an Amazon Elastic File System file system for task storage.

            • fileSystemIdrequired — (String)

              The Amazon EFS file system ID to use.

            • rootDirectory — (String)

              The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.

              If an EFS access point is specified in the authorizationConfig, the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.

            • transitEncryption — (String)

              Determines whether to use encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be turned on if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide.

              Possible values include:
              • "ENABLED"
              • "DISABLED"
            • transitEncryptionPort — (Integer)

              The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you do not specify a transit encryption port, it will use the port selection strategy that the Amazon EFS mount helper uses. For more information, see EFS mount helper in the Amazon Elastic File System User Guide.

            • authorizationConfig — (map)

              The authorization configuration details for the Amazon EFS file system.

              • accessPointId — (String)

                The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which will enforce the path set on the EFS access point. If an access point is used, transit encryption must be on in the EFSVolumeConfiguration. For more information, see Working with Amazon EFS access points in the Amazon Elastic File System User Guide.

              • iam — (String)

                Determines whether to use the Amazon ECS task role defined in a task definition when mounting the Amazon EFS file system. If it is turned on, transit encryption must be turned on in the EFSVolumeConfiguration. If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS access points in the Amazon Elastic Container Service Developer Guide.

        • memory — (String)

          The amount (in MiB) of memory used by the task.

          If your tasks runs on Amazon EC2 instances, you must specify either a task-level memory value or a container-level memory value. This field is optional and any value can be used. If a task-level memory value is specified, the container-level memory value is optional. For more information regarding container-level memory and memory reservation, see ContainerDefinition.

          If your tasks runs on Fargate, this field is required. You must use one of the following values. The value you choose determines your range of valid values for the cpu parameter.

        • pidMode — (String)

          The process namespace to use for the containers in the task. The valid values are host or task. On Fargate for Linux containers, the only valid value is task. For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.

          If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance.

          If task is specified, all containers within the specified task share the same process namespace.

          If no value is specified, the default is a private namespace for each container.

          If the host PID mode is used, there's a heightened risk of undesired process namespace exposure.

          Note: This parameter is not supported for Windows containers.
          Note: This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.

          • "task"
        • ipcMode — (String)

          The IPC resource namespace to use for the containers in the task. The valid values are host, task, or none. If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance.

          If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose.

          If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide.

          • For tasks that use the host IPC mode, IPC namespace related systemControls are not supported.

          • For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task.

          Note: This parameter is not supported for Windows containers or tasks run on Fargate.
          Possible values include:
          • "host"

          • weight — (Integer)

            The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

            If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

            An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

          • base — (Integer)

            The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

            A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

            For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

            For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.

            If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance. Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

          • loadBalancerName — (String)

            The name of the load balancer to associate with the Amazon ECS service or task set.

            If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

          • containerName — (String)

            The name of the container (as it appears in a container definition) to associate with the load balancer.

            You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

          • containerPort — (Integer)

            The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

        • serviceRegistries — (Array<map>)

          The details for the service discovery registries to assign to this task set. For more information, see Service discovery.

          • registryArn — (String)

            The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.

          • port — (Integer)

            The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.

          • containerName — (String)

            The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

          • containerPort — (Integer)

            The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

        • scale — (map)

          A floating-point percentage of your desired number of tasks to place and keep running in the task set.

          • value — (Float)

            The value, specified as a percent total of a service's desiredCount, to scale the task set. Accepted values are numbers between 0 and 100.

          • unit — (String)

            The unit of measure for the scale value.

            Possible values include:
            • "PERCENT"
        • stabilityStatus — (String)

          The stability status. This indicates whether the task set has reached a steady state. If the following conditions are met, the task set are in STEADY_STATE:

          • The task runningCount is equal to the computedDesiredCount.

          • The pendingCount is 0.

          • There are no tasks that are running on container instances in the DRAINING status.

          • All tasks are reporting a healthy status from the load balancers, service discovery, and container health checks.

          If any of those conditions aren't met, the stability status returns STABILIZING.

          Possible values include:
          • "STEADY_STATE"
          • "STABILIZING"
        • stabilityStatusAt — (Date)

          The Unix timestamp for the time when the task set stability status was retrieved.

        • tags — (Array<map>)

          The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value. You define both.

          The following basic restrictions apply to tags:

          • Maximum number of tags per resource - 50

          • For each resource, each tag key must be unique, and each tag key can have only one value.

          • Maximum key length - 128 Unicode characters in UTF-8

          • Maximum value length - 256 Unicode characters in UTF-8

          • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

          • Tag keys and values are case-sensitive.

          • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

          • key — (String)

            One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

          • value — (String)

            The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

        • fargateEphemeralStorage — (map)

          The Fargate ephemeral storage settings for the task set.

          • kmsKeyId — (String)

            Specify an Key Management Service key ID to encrypt the ephemeral storage for deployment.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

deregisterContainerInstance(params = {}, callback) ⇒ AWS.Request

Deregisters an Amazon ECS container instance from the specified cluster. This instance is no longer available to run tasks.

If you intend to use the container instance for some other purpose after deregistration, we recommend that you stop all of the tasks running on the container instance before deregistration. That prevents any orphaned tasks from consuming resources.

Deregistering a container instance removes the instance from a cluster, but it doesn't terminate the EC2 instance. If you are finished using the instance, be sure to terminate it in the Amazon EC2 console to stop billing.

Note: If you terminate a running container instance, Amazon ECS automatically deregisters the instance from your cluster (stopped container instances or instances with disconnected agents aren't automatically deregistered when terminated).

Service Reference:

Examples:

To deregister a container instance from a cluster


/* This example deregisters a container instance from the specified cluster in your default region. If there are still tasks running on the container instance, you must either stop those tasks before deregistering, or use the force option. */

 var params = {
  cluster: "default", 
  containerInstance: "container_instance_UUID", 
  force: true
 };
 ecs.deregisterContainerInstance(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*
   data = {
   }
   */
 });

Calling the deregisterContainerInstance operation

var params = {
  containerInstance: 'STRING_VALUE', /* required */
  cluster: 'STRING_VALUE',
  force: true || false
};
ecs.deregisterContainerInstance(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • cluster — (String)

      The short name or full Amazon Resource Name (ARN) of the cluster that hosts the container instance to deregister. If you do not specify a cluster, the default cluster is assumed.

    • containerInstance — (String)

      The container instance ID or full ARN of the container instance to deregister. For more information about the ARN format, see Amazon Resource Name (ARN) in the Amazon ECS Developer Guide.

    • force — (Boolean)

      Forces the container instance to be deregistered. If you have tasks running on the container instance when you deregister it with the force option, these tasks remain running until you terminate the instance or the tasks stop through some other means, but they're orphaned (no longer monitored or accounted for by Amazon ECS). If an orphaned task on your container instance is part of an Amazon ECS service, then the service scheduler starts another copy of that task, on a different container instance if possible.

      Any containers in orphaned service tasks that are registered with a Classic Load Balancer or an Application Load Balancer target group are deregistered. They begin connection draining according to the settings on the load balancer or target group.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

For port resource types, this parameter describes the ports that were reserved by the Amazon ECS container agent (at instance registration time) and any task containers that have reserved port mappings on the host (with the host or bridge network mode). Any port that's not specified here is available for new tasks.

          • name — (String)

            The name of the resource, such as CPU, MEMORY, PORTS, PORTS_UDP, or a user-defined resource.

          The status of the container instance. The valid values are REGISTERING, REGISTRATION_FAILED, ACTIVE, INACTIVE, DEREGISTERING, or DRAINING.

          If your account has opted in to the awsvpcTrunking account setting, then any newly registered container instance will transition to a REGISTERING status while the trunk elastic network interface is provisioned for the instance. If the registration fails, the instance will transition to a REGISTRATION_FAILED status. You can describe the container instance and see the reason for failure in the statusReason parameter. Once the container instance is terminated, the instance transitions to a DEREGISTERING status while the trunk elastic network interface is deprovisioned. The instance then transitions to an INACTIVE status.

          The ACTIVE status indicates that the container instance can accept tasks. The DRAINING indicates that new tasks aren't placed on the container instance and any service tasks running on the container instance are removed if possible. For more information, see Container instance draining in the Amazon Elastic Container Service Developer Guide.

deregisterTaskDefinition(params = {}, callback) ⇒ AWS.Request

Deregisters the specified task definition by family and revision. Upon deregistration, the task definition is marked as INACTIVE. Existing tasks and services that reference an INACTIVE task definition continue to run without disruption. Existing services that reference an INACTIVE task definition can still scale up or down by modifying the service's desired count. If you want to delete a task definition revision, you must first deregister the task definition revision.

You can't use an INACTIVE task definition to run new tasks or create new services, and you can't update an existing service to reference an INACTIVE task definition. However, there may be up to a 10-minute window following deregistration where these restrictions have not yet taken effect.

Note: At this time, INACTIVE task definitions remain discoverable in your account indefinitely. However, this behavior is subject to change in the future. We don't recommend that you rely on INACTIVE task definitions persisting beyond the lifecycle of any associated tasks and services.

You must deregister a task definition revision before you delete it. For more information, see DeleteTaskDefinitions.

Service Reference:

Examples:

Calling the deregisterTaskDefinition operation

var params = {
  taskDefinition: 'STRING_VALUE' /* required */
};
ecs.deregisterTaskDefinition(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • taskDefinition — (String)

      The family and revision (family:revision) or full Amazon Resource Name (ARN) of the task definition to deregister. You must specify a revision.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • taskDefinition — (map)

        The full description of the deregistered task.

        • taskDefinitionArn — (String)

          The full Amazon Resource Name (ARN) of the task definition.

        • containerDefinitions — (Array<map>)

          A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.

          • name — (String)

            The name of a container. If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in tthe docker conainer create command and the --name option to docker run.

          • image — (String)

            The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the docker conainer create command and the IMAGE parameter of docker run.

            • When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.

            • Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag or registry/repository@digest. For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE.

            • Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo).

            • Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent).

            • Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu).

          • repositoryCredentials — (map)

            The private repository authentication credentials to use.

            • credentialsParameterrequired — (String)

              The Amazon Resource Name (ARN) of the secret containing the private repository credentials.

              Note: When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
          • cpu — (Integer)

            The number of cpu units reserved for the container. This parameter maps to CpuShares in the docker conainer create commandand the --cpu-shares option to docker run.

            This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.

            Note: You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.

            Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.

            On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. The minimum valid CPU share value that the Linux kernel allows is 2, and the maximum valid CPU share value that the Linux kernel allows is 262144. However, the CPU parameter isn't required, and you can use CPU values below 2 or above 262144 in your container definitions. For CPU values below 2 (including null) or above 262144, the behavior varies based on your Amazon ECS container agent version:

            • Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.

            • Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.

            • Agent versions greater than or equal to 1.84.0: CPU values greater than 256 vCPU are passed to Docker as 256, which is equivalent to 262144 CPU shares.

            On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0, which Windows interprets as 1% of one CPU.

          • memory — (Integer)

            The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in thethe docker conainer create command and the --memory option to docker run.

            If using the Fargate launch type, this parameter is optional.

            If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.

            The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.

            The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.

          • memoryReservation — (Integer)

            The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the the docker conainer create command and the --memory-reservation option to docker run.

            If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.

            For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.

            The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.

            The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.

          • links — (Array<String>)

            The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge. The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.. This parameter maps to Links in the docker conainer create command and the --link option to docker run.

            Note: This parameter is not supported for Windows containers.

            Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.

          • portMappings — (Array<map>)

            The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.

            For task definitions that use the awsvpc network mode, only specify the containerPort. The hostPort can be left blank or it must be the same value as the containerPort.

            Port mappings on Windows use the NetNAT gateway address rather than localhost. There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.

            This parameter maps to PortBindings in the the docker conainer create command and the --publish option to docker run. If the network mode of a task definition is set to none, then you can't specify port mappings. If the network mode of a task definition is set to host, then host ports must either be undefined or they must match the container port in the port mapping.

            Note: After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.
            • containerPort — (Integer)

              The port number on the container that's bound to the user-specified or automatically assigned host port.

              If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort.

              If you use containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort. Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.

            • hostPort — (Integer)

              The port number on the container instance to reserve for your container.

              If you specify a containerPortRange, leave this field empty and the value of the hostPort is set as follows:

              • For containers in a task with the awsvpc network mode, the hostPort is set to the same value as the containerPort. This is a static mapping strategy.

              • For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.

              If you use containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort.

              If you use containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.

              The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.

              The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.

            • protocol — (String)

              The protocol used for the port mapping. Valid values are tcp and udp. The default is tcp. protocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.

              Possible values include:
              • "tcp"
              • "udp"
            • name — (String)

              The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the serviceConnectConfiguration of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

              For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

            • appProtocol — (String)

              The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.

              If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.

              appProtocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.

              Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

              Possible values include:
              • "http"
              • "http2"
              • "grpc"
            • containerPortRange — (String)

              The port number range on the container that's bound to the dynamically mapped host port range.

              The following rules apply when you specify a containerPortRange:

              • You must use either the bridge network mode or the awsvpc network mode.

              • This parameter is available for both the EC2 and Fargate launch types.

              • This parameter is available for both the Linux and Windows operating systems.

              • The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package

              • You can specify a maximum of 100 port ranges per container.

              • You do not specify a hostPortRange. The value of the hostPortRange is set as follows:

                • For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange. This is a static mapping strategy.

                • For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.

              • The containerPortRange valid values are between 1 and 65535.

              • A port can only be included in one port mapping per container.

              • You cannot specify overlapping port ranges.

              • The first port in the range must be less than last port in the range.

              • Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.

                For more information, see Issue #11185 on the Github website.

                For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.

              You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.

          • essential — (Boolean)

            If the essential parameter of a container is marked as true, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.

            All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.

          • restartPolicy — (map)

            The restart policy for a container. When you set up a restart policy, Amazon ECS can restart the container without needing to replace the task. For more information, see Restart individual containers in Amazon ECS tasks with container restart policies in the Amazon Elastic Container Service Developer Guide.

            • enabledrequired — (Boolean)

              Specifies whether a restart policy is enabled for the container.

            • ignoredExitCodes — (Array<Integer>)

              A list of exit codes that Amazon ECS will ignore and not attempt a restart on. You can specify a maximum of 50 container exit codes. By default, Amazon ECS does not ignore any exit codes.

            • restartAttemptPeriod — (Integer)

              A period of time (in seconds) that the container must run for before a restart can be attempted. A container can be restarted only once every restartAttemptPeriod seconds. If a container isn't able to run for this time period and exits early, it will not be restarted. You can set a minimum restartAttemptPeriod of 60 seconds and a maximum restartAttemptPeriod of 1800 seconds. By default, a container must run for 300 seconds before it can be restarted.

          • entryPoint — (Array<String>)

            Early versions of the Amazon ECS container agent don't properly handle entryPoint parameters. If you have problems using entryPoint, update your container agent or enter your commands and arguments as command array items instead.

            The entry point that's passed to the container. This parameter maps to Entrypoint in tthe docker conainer create command and the --entrypoint option to docker run.

          • command — (Array<String>)

            The command that's passed to the container. This parameter maps to Cmd in the docker conainer create command and the COMMAND parameter to docker run. If there are multiple arguments, each argument is a separated string in the array.

          • environment — (Array<map>)

            The environment variables to pass to a container. This parameter maps to Env in the docker conainer create command and the --env option to docker run.

            We don't recommend that you use plaintext environment variables for sensitive information, such as credential data.

            • name — (String)

              The name of the key-value pair. For environment variables, this is the name of the environment variable.

            • value — (String)

              The value of the key-value pair. For environment variables, this is the value of the environment variable.

          • environmentFiles — (Array<map>)

            A list of files containing the environment variables to pass to a container. This parameter maps to the --env-file option to docker run.

            You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file contains an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored.

            If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide.

            • valuerequired — (String)

              The Amazon Resource Name (ARN) of the Amazon S3 object containing the environment variable file.

            • typerequired — (String)

              The file type to use. Environment files are objects in Amazon S3. The only supported value is s3.

              Possible values include:
              • "s3"
          • mountPoints — (Array<map>)

            The mount points for data volumes in your container.

            This parameter maps to Volumes in the the docker conainer create command and the --volume option to docker run.

            Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives.

            • sourceVolume — (String)

              The name of the volume to mount. Must be a volume name referenced in the name parameter of task definition volume.

            • containerPath — (String)

              The path on the container to mount the host volume at.

            • readOnly — (Boolean)

              If this value is true, the container has read-only access to the volume. If this value is false, then the container can write to the volume. The default value is false.

          • volumesFrom — (Array<map>)

            Data volumes to mount from another container. This parameter maps to VolumesFrom in tthe docker conainer create command and the --volumes-from option to docker run.

            • sourceContainer — (String)

              The name of another container within the same task definition to mount volumes from.

            • readOnly — (Boolean)

              If this value is true, the container has read-only access to the volume. If this value is false, then the container can write to the volume. The default value is false.

          • linuxParameters — (map)

            Linux-specific modifications that are applied to the container, such as Linux kernel capabilities. For more information see KernelCapabilities.

            Note: This parameter is not supported for Windows containers.
            • capabilities — (map)

              The Linux capabilities for the container that are added to or dropped from the default configuration provided by Docker.

              Note: For tasks that use the Fargate launch type, capabilities is supported for all platform versions but the add parameter is only supported if using platform version 1.4.0 or later.
              • add — (Array<String>)

                The Linux capabilities for the container that have been added to the default configuration provided by Docker. This parameter maps to CapAdd in the docker conainer create command and the --cap-add option to docker run.

                Note: Tasks launched on Fargate only support adding the SYS_PTRACE kernel capability.

                Valid values: "ALL" | "AUDIT_CONTROL" | "AUDIT_WRITE" | "BLOCK_SUSPEND" | "CHOWN" | "DAC_OVERRIDE" | "DAC_READ_SEARCH" | "FOWNER" | "FSETID" | "IPC_LOCK" | "IPC_OWNER" | "KILL" | "LEASE" | "LINUX_IMMUTABLE" | "MAC_ADMIN" | "MAC_OVERRIDE" | "MKNOD" | "NET_ADMIN" | "NET_BIND_SERVICE" | "NET_BROADCAST" | "NET_RAW" | "SETFCAP" | "SETGID" | "SETPCAP" | "SETUID" | "SYS_ADMIN" | "SYS_BOOT" | "SYS_CHROOT" | "SYS_MODULE" | "SYS_NICE" | "SYS_PACCT" | "SYS_PTRACE" | "SYS_RAWIO" | "SYS_RESOURCE" | "SYS_TIME" | "SYS_TTY_CONFIG" | "SYSLOG" | "WAKE_ALARM"

              • drop — (Array<String>)

                The Linux capabilities for the container that have been removed from the default configuration provided by Docker. This parameter maps to CapDrop in the docker conainer create command and the --cap-drop option to docker run.

                Valid values: "ALL" | "AUDIT_CONTROL" | "AUDIT_WRITE" | "BLOCK_SUSPEND" | "CHOWN" | "DAC_OVERRIDE" | "DAC_READ_SEARCH" | "FOWNER" | "FSETID" | "IPC_LOCK" | "IPC_OWNER" | "KILL" | "LEASE" | "LINUX_IMMUTABLE" | "MAC_ADMIN" | "MAC_OVERRIDE" | "MKNOD" | "NET_ADMIN" | "NET_BIND_SERVICE" | "NET_BROADCAST" | "NET_RAW" | "SETFCAP" | "SETGID" | "SETPCAP" | "SETUID" | "SYS_ADMIN" | "SYS_BOOT" | "SYS_CHROOT" | "SYS_MODULE" | "SYS_NICE" | "SYS_PACCT" | "SYS_PTRACE" | "SYS_RAWIO" | "SYS_RESOURCE" | "SYS_TIME" | "SYS_TTY_CONFIG" | "SYSLOG" | "WAKE_ALARM"

            • devices — (Array<map>)

              Any host devices to expose to the container. This parameter maps to Devices in tthe docker conainer create command and the --device option to docker run.

              Note: If you're using tasks that use the Fargate launch type, the devices parameter isn't supported.
              • hostPathrequired — (String)

                The path for the device on the host container instance.

              • containerPath — (String)

                The path inside the container at which to expose the host device.

              • permissions — (Array<String>)

            • initProcessEnabled — (Boolean)

              Run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

            • sharedMemorySize — (Integer)

              The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run.

              Note: If you are using tasks that use the Fargate launch type, the sharedMemorySize parameter is not supported.
            • tmpfs — (Array<map>)

              The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run.

              Note: If you're using tasks that use the Fargate launch type, the tmpfs parameter isn't supported.
              • containerPathrequired — (String)

                The absolute file path where the tmpfs volume is to be mounted.

              • sizerequired — (Integer)

                The maximum size (in MiB) of the tmpfs volume.

              • mountOptions — (Array<String>)

                The list of tmpfs volume mount options.

                Valid values: "defaults" | "ro" | "rw" | "suid" | "nosuid" | "dev" | "nodev" | "exec" | "noexec" | "sync" | "async" | "dirsync" | "remount" | "mand" | "nomand" | "atime" | "noatime" | "diratime" | "nodiratime" | "bind" | "rbind" | "unbindable" | "runbindable" | "private" | "rprivate" | "shared" | "rshared" | "slave" | "rslave" | "relatime" | "norelatime" | "strictatime" | "nostrictatime" | "mode" | "uid" | "gid" | "nr_inodes" | "nr_blocks" | "mpol"

            • maxSwap — (Integer)

              The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value.

              If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.

              Note: If you're using tasks that use the Fargate launch type, the maxSwap parameter isn't supported. If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.
            • swappiness — (Integer)

              This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100. If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run.

              Note: If you're using tasks that use the Fargate launch type, the swappiness parameter isn't supported. If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.
          • secrets — (Array<map>)

            The secrets to pass to the container. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide.

            • namerequired — (String)

              The name of the secret.

            • valueFromrequired — (String)

              The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.

              For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide.

              Note: If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
          • dependsOn — (Array<map>)

            The dependencies defined for container startup and shutdown. A container can contain multiple dependencies on other containers in a task definition. When a dependency is defined for container startup, for container shutdown it is reversed.

            For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

            For tasks using the Fargate launch type, the task or service requires the following platforms:

            • Linux platform version 1.3.0 or later.

            • Windows platform version 1.0.0 or later.

            • containerNamerequired — (String)

              The name of a container.

            • conditionrequired — (String)

              The dependency condition of the container. The following are the available conditions and their behavior:

              • START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.

              • COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.

              • SUCCESS - This condition is the same as COMPLETE, but it also requires that the container exits with a zero status. This condition can't be set on an essential container.

              • HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.

              Possible values include:
              • "START"
              • "COMPLETE"
              • "SUCCESS"
              • "HEALTHY"
          • startTimeout — (Integer)

            Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE, SUCCESS, or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state.

            Note: When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it's enforced independently from this start timeout value.

            For tasks using the Fargate launch type, the task or service requires the following platforms:

            • Linux platform version 1.3.0 or later.

            • Windows platform version 1.0.0 or later.

            For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

            The valid values for Fargate are 2-120 seconds.

          • stopTimeout — (Integer)

            Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.

            For tasks using the Fargate launch type, the task or service requires the following platforms:

            • Linux platform version 1.3.0 or later.

            • Windows platform version 1.0.0 or later.

            The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.

            For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

            The valid values are 2-120 seconds.

          • hostname — (String)

            The hostname to use for your container. This parameter maps to Hostname in thethe docker conainer create command and the --hostname option to docker run.

          • user — (String)

            The user to use inside the container. This parameter maps to User in the docker conainer create command and the --user option to docker run.

            When running tasks using the host network mode, don't run containers using the root user (UID 0). We recommend using a non-root user for better security.

            You can specify the user using the following formats. If specifying a UID or GID, you must specify it as a positive integer.

            • user

            • user:group

            • uid

            • uid:gid

            • user:gid

            When this parameter is true, networking is off within the container. This parameter maps to NetworkDisabled in the docker conainer create command.

            Note: This parameter is not supported for Windows containers.
          • privileged — (Boolean)

            When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root user). This parameter maps to Privileged in the the docker conainer create command and the --privileged option to docker run

            Note: This parameter is not supported for Windows containers or tasks run on Fargate.
          • readonlyRootFilesystem — (Boolean)

            When this parameter is true, the container is given read-only access to its root file system. This parameter maps to ReadonlyRootfs in the docker conainer create command and the --read-only option to docker run.

            Note: This parameter is not supported for Windows containers.
          • dnsServers — (Array<String>)

            A list of DNS servers that are presented to the container. This parameter maps to Dns in the the docker conainer create command and the --dns option to docker run.

          • dockerSecurityOptions — (Array<String>)

            A list of strings to provide custom configuration for multiple security systems. This field isn't valid for containers in tasks using the Fargate launch type.

            For Linux tasks on EC2, this parameter can be used to reference custom labels for SELinux and AppArmor multi-level security systems.

            For any tasks on EC2, this parameter can be used to reference a credential spec file that configures a container for Active Directory authentication. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers in the Amazon Elastic Container Service Developer Guide.

            This parameter maps to SecurityOpt in the docker conainer create command and the --security-opt option to docker run.

            Note: The Amazon ECS container agent running on a container instance must register with the ECS_SELINUX_CAPABLE=true or ECS_APPARMOR_CAPABLE=true environment variables before containers placed on that instance can use these security options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.

            Valid values: "no-new-privileges" | "apparmor:PROFILE" | "label:value" | "credentialspec:CredentialSpecFilePath"

          • interactive — (Boolean)

            When this parameter is true, a TTY is allocated. This parameter maps to Tty in tthe docker conainer create command and the --tty option to docker run.

          • dockerLabels — (map<String>)

            A key/value map of labels to add to the container. This parameter maps to Labels in the docker conainer create command and the --label option to docker run. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

          • ulimits — (Array<map>)

            A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it overrides the default values set by Docker. This parameter maps to Ulimits in tthe docker conainer create command and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type.

            Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 65535 and the default hard limit is 65535.

            This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

              The hard limit for the ulimit type.

          • logConfiguration — (map)

            The log configuration specification for the container.

            This parameter maps to LogConfig in the docker conainer create command and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options).

            Note: Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.

            This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

            Note: The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.
            • logDriverrequired — (String)

              The log driver to use for the container.

              For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

              For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, syslog, splunk, and awsfirelens.

              For more information about using the awslogs log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.

              For more information about using the awsfirelens log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.

              Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
              Possible values include:
              • "json-file"
              • "syslog"

            • secretOptions — (Array<map>)

              The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide.

              • namerequired — (String)

                The name of the secret.

              • valueFromrequired — (String)

                The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.

                For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide.

                Note: If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
          • healthCheck — (map)

            The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the docker conainer create command and the HEALTHCHECK parameter of docker run.

            • commandrequired — (Array<String>)

              A string array representing the command that the container runs to determine if it is healthy. The string array must start with CMD to run the command arguments directly, or CMD-SHELL to run the command with the container's default shell.

              When you use the Amazon Web Services Management Console JSON panel, the Command Line Interface, or the APIs, enclose the list of commands in double quotes and brackets.

              [ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]

              You don't include the double quotes and brackets when you use the Amazon Web Services Management Console.

              CMD-SHELL, curl -f http://localhost/ || exit 1

              An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in tthe docker conainer create command

            • interval — (Integer)

              The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.

              The time period in seconds to wait for a health check to succeed before it is considered a failure. You may specify between 2 and 60 seconds. The default value is 5.

            • retries — (Integer)

              The number of times to retry a failed health check before the container is considered unhealthy. You may specify between 1 and 10 retries. The default value is 3.

            • startPeriod — (Integer)

              The optional grace period to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You can specify between 0 and 300 seconds. By default, the startPeriod is off.

              Note: If a health check succeeds within the startPeriod, then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
          • systemControls — (Array<map>)

            A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in tthe docker conainer create command and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.

            • namespace — (String)

              The namespaced kernel parameter to set a value for.

            • value — (String)

            • options — (map<String>)

              The options to use when configuring the log router. This field is optional and can be used to specify a custom configuration file or to add additional metadata, such as the task, task definition, cluster, and container instance details to the log event. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"}. For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide.

              Note: Tasks hosted on Fargate only support the file configuration file type.
          • credentialSpecs — (Array<String>)

            A list of ARNs in SSM or Amazon S3 to a credential spec (CredSpec) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of the dockerSecurityOptions. The maximum number of ARNs is 1.

            There are two formats for each ARN.

            credentialspecdomainless:MyARN

            You use credentialspecdomainless:MyARN to provide a CredSpec with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.

            Each task that runs on any container instance can join different domains.

            You can use this format without joining the container instance to a domain.

            credentialspec:MyARN

            You use credentialspec:MyARN to provide a CredSpec for a single domain.

            You must join the container instance to the domain before you start any tasks that use this task definition.

            In both formats, replace MyARN with the ARN in SSM or Amazon S3.

            If you provide a credentialspecdomainless:MyARN, the credspec must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.

        • family — (String)

          The name of a family that this task definition is registered to. Up to 255 characters are allowed. Letters (both uppercase and lowercase letters), numbers, hyphens (-), and underscores (_) are allowed.

          A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.

        • taskRoleArn — (String)

          The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

        • executionRoleArn — (String)

          The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

        • networkMode — (String)

          The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. If no network mode is specified, the default is bridge.

          For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.

          With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.

          When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.

          If the network mode is awsvpc, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

          If the network mode is host, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.

          Possible values include:
          • "bridge"
          • "host"
          • "awsvpc"
          • "none"
        • revision — (Integer)

          The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is 1. Each time that you register a new revision of a task definition in the same family, the revision value always increases by one. This is even if you deregistered previous revisions in this family.

        • volumes — (Array<map>)

          The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide.

          Note: The host and sourcePath parameters aren't supported for tasks run on Fargate.
          • name — (String)

            The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.

            When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task.

            For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition.

            When a volume is using the efsVolumeConfiguration, the name is required.

          • host — (map)

            This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.

            Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D::D:\, but not D:\my\path:C:\my\path or D::C:\my\path.

            • sourcePath — (String)

              When the host parameter is used, specify a sourcePath to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.

              If you're using the Fargate launch type, the sourcePath parameter is not supported.

          • dockerVolumeConfiguration — (map)

            This parameter is specified when you use Docker volumes.

            Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.

            Note: Docker volumes aren't supported by tasks run on Fargate.
            • scope — (String)

              The scope for the Docker volume that determines its lifecycle. Docker volumes that are scoped to a task are automatically provisioned when the task starts and destroyed when the task stops. Docker volumes that are scoped as shared persist after the task stops.

              Possible values include:
              • "task"
              • "shared"
            • autoprovision — (Boolean)

              If this value is true, the Docker volume is created if it doesn't already exist.

              Note: This field is only used if the scope is shared.
            • driver — (String)

              The Docker volume driver to use. The driver value must match the driver name provided by Docker because it is used for task placement. If the driver was installed using the Docker plugin CLI, use docker plugin ls to retrieve the driver name from your container instance. If the driver was installed using another method, use Docker plugin discovery to retrieve the driver name. This parameter maps to Driver in the docker conainer create command and the xxdriver option to docker volume create.

            • driverOpts — (map<String>)

              A map of Docker driver-specific options passed through. This parameter maps to DriverOpts in the docker create-volume command and the xxopt option to docker volume create.

            • labels — (map<String>)

              Custom metadata to add to your Docker volume. This parameter maps to Labels in the docker conainer create command and the xxlabel option to docker volume create.

          • efsVolumeConfiguration — (map)

            This parameter is specified when you use an Amazon Elastic File System file system for task storage.

            • fileSystemIdrequired — (String)

              The Amazon EFS file system ID to use.

            • rootDirectory — (String)

              The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.

              If an EFS access point is specified in the authorizationConfig, the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.

            • transitEncryption — (String)

              Determines whether to use encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be turned on if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide.

              Possible values include:
              • "ENABLED"
              • "DISABLED"
            • transitEncryptionPort — (Integer)

              The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you do not specify a transit encryption port, it will use the port selection strategy that the Amazon EFS mount helper uses. For more information, see EFS mount helper in the Amazon Elastic File System User Guide.

            • authorizationConfig — (map)

              The authorization configuration details for the Amazon EFS file system.

              • accessPointId — (String)

                The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which will enforce the path set on the EFS access point. If an access point is used, transit encryption must be on in the EFSVolumeConfiguration. For more information, see Working with Amazon EFS access points in the Amazon Elastic File System User Guide.

              • iam — (String)

                Determines whether to use the Amazon ECS task role defined in a task definition when mounting the Amazon EFS file system. If it is turned on, transit encryption must be turned on in the EFSVolumeConfiguration. If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS access points in the Amazon Elastic Container Service Developer Guide.

                Possible values include:
                • "ENABLED"
                • "DISABLED"

              • credentialsParameterrequired — (String)

                The authorization credential option to use. The authorization credential options can be provided using either the Amazon Resource Name (ARN) of an Secrets Manager secret or SSM Parameter Store parameter. The ARN refers to the stored credentials.

              • domainrequired — (String)

                A fully qualified domain name hosted by an Directory Service Managed Microsoft AD (Active Directory) or self-hosted AD on Amazon EC2.

          • configuredAtLaunch — (Boolean)

            Indicates whether the volume should be configured at launch time. This is used to create Amazon EBS volumes for standalone tasks or tasks created as part of a service. Each task definition revision may only have one volume configured at launch in the volume configuration.

            To configure a volume at launch time, use this task definition revision and specify a volumeConfigurations object when calling the CreateService, UpdateService, RunTask or StartTask APIs.

        • status — (String)

          The status of the task definition.

          Possible values include:

          • "DELETE_IN_PROGRESS"
        • requiresAttributes — (Array<map>)

          The container instance attributes required by your task. When an Amazon EC2 instance is registered to your cluster, the Amazon ECS container agent assigns some standard attributes to the instance. You can apply custom attributes. These are specified as key-value pairs using the Amazon ECS console or the PutAttributes API. These attributes are used when determining task placement for tasks hosted on Amazon EC2 instances. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide.

          Note: This parameter isn't supported for tasks run on Fargate.
          • namerequired — (String)

            The name of the attribute. The name must contain between 1 and 128 characters. The name may contain letters (uppercase and lowercase), numbers, hyphens (-), underscores (_), forward slashes (/), back slashes (), or periods (.).

          • value — (String)

            The value of the attribute. The value must contain between 1 and 128 characters. It can contain letters (uppercase and lowercase), numbers, hyphens (-), underscores (_), periods (.), at signs (@), forward slashes (/), back slashes (), colons (:), or spaces. The value can't start or end with a space.

          • targetType — (String)

            The type of the target to attach the attribute with. This parameter is required if you use the short form ID for a resource instead of the full ARN.

        • compatibilities — (Array<String>)

          The task launch types the task definition validated against during task definition registration. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

        • runtimePlatform — (map)

          The operating system that your task definitions are running on. A platform family is specified only for tasks using the Fargate launch type.

          When you specify a task in a service, this value must match the runtimePlatform value of the service.

          • cpuArchitecture — (String)

            The CPU architecture.

            You can run your Linux tasks on an ARM-based platform by setting the value to ARM64. This option is available for tasks that run on Linux Amazon EC2 instance or Linux containers on Fargate.

            Possible values include:

            • "LINUX"
        • requiresCompatibilities — (Array<String>)

          The task launch types the task definition was validated against. The valid values are EC2, FARGATE, and EXTERNAL. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

        • cpu — (String)

          The number of cpu units used by the task. If you use the EC2 launch type, this field is optional. Any value can be used. If you use the Fargate launch type, this field is required. You must use one of the following values. The value that you choose determines your range of valid values for the memory parameter.

          If you use the EC2 launch type, this field is optional. Supported values are between 128 CPU units (0.125 vCPUs) and 10240 CPU units (10 vCPUs).

          The CPU units cannot be less than 1 vCPU when you use Windows containers on Fargate.

          • 256 (.25 vCPU) - Available memory values: 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB)

          • 4096 (4 vCPU) - Available memory values: 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB)

          • 8192 (8 vCPU) - Available memory values: 16 GB and 60 GB in 4 GB increments

            This option requires Linux platform 1.4.0 or later.

          • 16384 (16vCPU) - Available memory values: 32GB and 120 GB in 8 GB increments

            This option requires Linux platform 1.4.0 or later.

        • memory — (String)

          The amount (in MiB) of memory used by the task.

          If your tasks runs on Amazon EC2 instances, you must specify either a task-level memory value or a container-level memory value. This field is optional and any value can be used. If a task-level memory value is specified, the container-level memory value is optional. For more information regarding container-level memory and memory reservation, see ContainerDefinition.

          If your tasks runs on Fargate, this field is required. You must use one of the following values. The value you choose determines your range of valid values for the cpu parameter.

          • 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) - Available cpu values: 256 (.25 vCPU)

          • 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) - Available cpu values: 512 (.5 vCPU)

        • inferenceAccelerators — (Array<map>)

          The Elastic Inference accelerator that's associated with the task.

          • deviceNamerequired — (String)

            The Elastic Inference accelerator device name. The deviceName must also be referenced in a container definition as a ResourceRequirement.

          • deviceTyperequired — (String)

            The Elastic Inference accelerator type to use.

        • pidMode — (String)

          The process namespace to use for the containers in the task. The valid values are host or task. On Fargate for Linux containers, the only valid value is task. For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.

          If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance.

          If task is specified, all containers within the specified task share the same process namespace.

          If no value is specified, the default is a private namespace for each container.

          If the host PID mode is used, there's a heightened risk of undesired process namespace exposure.

          Note: This parameter is not supported for Windows containers.
          Note: This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.
          Possible values include:
          • "host"
          • "task"
        • ipcMode — (String)

          The IPC resource namespace to use for the containers in the task. The valid values are host, task, or none. If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance.

          If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose.

          If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide.

          • For tasks that use the host IPC mode, IPC namespace related systemControls are not supported.

          • For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task.

          Note: This parameter is not supported for Windows containers or tasks run on Fargate.
          Possible values include:
          • "host"

If your container instances are launched from the Amazon ECS optimized AMI version 20190301 or later, they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

          • type — (String)

            The proxy type. The only supported value is APPMESH.

            Possible values include:
            • "APPMESH"
          • containerNamerequired — (String)

            The name of the container that will serve as the App Mesh proxy.

Service Reference:

Examples:

Calling the describeCapacityProviders operation

var params = {
  capacityProviders: [
    'STRING_VALUE',
    /* more items */
  ],
  include: [
    TAGS,
    /* more items */
  ],
  maxResults: 'NUMBER_VALUE',
  nextToken: 'STRING_VALUE'
};
ecs.describeCapacityProviders(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • capacityProviders — (Array<String>)

      The short name or full Amazon Resource Name (ARN) of one or more capacity providers. Up to 100 capacity providers can be described in an action.

    • include — (Array<String>)

      Specifies whether or not you want to see the resource tags for the capacity provider. If TAGS is specified, the tags are included in the response. If this field is omitted, tags aren't included in the response.

    • maxResults — (Integer)

      The maximum number of account setting results returned by DescribeCapacityProviders in paginated output. When this parameter is used, DescribeCapacityProviders only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another DescribeCapacityProviders request with the returned nextToken value. This value can be between 1 and 10. If this parameter is not used, then DescribeCapacityProviders returns up to 10 results and a nextToken value if applicable.

    • nextToken — (String)

      The nextToken value returned from a previous paginated DescribeCapacityProviders request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value.

      Note: This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • capacityProviders — (Array<map>)

        The list of capacity providers.

        • capacityProviderArn — (String)

          The Amazon Resource Name (ARN) that identifies the capacity provider.

        • name — (String)

          The name of the capacity provider.

        • status — (String)

          The current status of the capacity provider. Only capacity providers in an ACTIVE state can be used in a cluster. When a capacity provider is successfully deleted, it has an INACTIVE status.

          Possible values include:
          • "ACTIVE"
          • "INACTIVE"
        • autoScalingGroupProvider — (map)

          The Auto Scaling group settings for the capacity provider.

          • autoScalingGroupArnrequired — (String)

            The Amazon Resource Name (ARN) that identifies the Auto Scaling group, or the Auto Scaling group name.

          • managedScaling — (map)

            The managed scaling settings for the Auto Scaling group capacity provider.

            • status — (String)

              Determines whether to use managed scaling for the capacity provider.

              Possible values include:
              • "ENABLED"
              • "DISABLED"
            • targetCapacity — (Integer)

              The target capacity utilization as a percentage for the capacity provider. The specified value must be greater than 0 and less than or equal to 100. For example, if you want the capacity provider to maintain 10% spare capacity, then that means the utilization is 90%, so use a targetCapacity of 90. The default value of 100 percent results in the Amazon EC2 instances in your Auto Scaling group being completely used.

            • minimumScalingStepSize — (Integer)

              The minimum number of Amazon EC2 instances that Amazon ECS will scale out at one time. The scale in process is not affected by this parameter If this parameter is omitted, the default value of 1 is used.

              When additional capacity is required, Amazon ECS will scale up the minimum scaling step size even if the actual demand is less than the minimum scaling step size.

              If you use a capacity provider with an Auto Scaling group configured with more than one Amazon EC2 instance type or Availability Zone, Amazon ECS will scale up by the exact minimum scaling step size value and will ignore both the maximum scaling step size as well as the capacity demand.

            • maximumScalingStepSize — (Integer)

              The maximum number of Amazon EC2 instances that Amazon ECS will scale out at one time. If this parameter is omitted, the default value of 10000 is used.

            • instanceWarmupPeriod — (Integer)

              The period of time, in seconds, after a newly launched Amazon EC2 instance can contribute to CloudWatch metrics for Auto Scaling group. If this parameter is omitted, the default value of 300 seconds is used.

          • managedTerminationProtection — (String)

            The managed termination protection setting to use for the Auto Scaling group capacity provider. This determines whether the Auto Scaling group has managed termination protection. The default is off.

            When using managed termination protection, managed scaling must also be used otherwise managed termination protection doesn't work.

            When managed termination protection is on, Amazon ECS prevents the Amazon EC2 instances in an Auto Scaling group that contain tasks from being terminated during a scale-in action. The Auto Scaling group and each instance in the Auto Scaling group must have instance protection from scale-in actions on as well. For more information, see Instance Protection in the Auto Scaling User Guide.

            When managed termination protection is off, your Amazon EC2 instances aren't protected from termination when the Auto Scaling group scales in.

            Possible values include:
            • "ENABLED"
            • "DISABLED"
          • managedDraining — (String)

            The managed draining option for the Auto Scaling group capacity provider. When you enable this, Amazon ECS manages and gracefully drains the EC2 container instances that are in the Auto Scaling group capacity provider.

          The capacity provider was successfully deleted and has an INACTIVE status.

          DELETE_FAILED

          The capacity provider can't be deleted. The update status reason provides further details about why the delete failed.

          Possible values include:
          • "DELETE_IN_PROGRESS"
          • "DELETE_COMPLETE"
          • "DELETE_FAILED"
          • "UPDATE_IN_PROGRESS"
          • "UPDATE_COMPLETE"
          • "UPDATE_FAILED"
        • updateStatusReason — (String)

          The update status reason. This provides further details about the update status for the capacity provider.

        • tags — (Array<map>)

          The metadata that you apply to the capacity provider to help you categorize and organize it. Each tag consists of a key and an optional value. You define both.

          The following basic restrictions apply to tags:

          • Maximum number of tags per resource - 50

          • For each resource, each tag key must be unique, and each tag key can have only one value.

          • Maximum key length - 128 Unicode characters in UTF-8

          • Maximum value length - 256 Unicode characters in UTF-8

          • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

          • Tag keys and values are case-sensitive.

          • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

          • key — (String)

            One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

          • value — (String)

            The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

      • failures — (Array<map>)

          • weight — (Integer)

            The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

            If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

            An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

          • base — (Integer)

            The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

            For Elastic Block Storage, this includes roleArn, deleteOnTermination, volumeName, volumeId, and statusReason (only when the attachment fails to create or attach).

            • name — (String)

              The name of the key-value pair. For environment variables, this is the name of the environment variable.

            • value — (String)

              The value of the key-value pair. For environment variables, this is the value of the environment variable.

        • attachmentsStatus — (String)

          The status of the capacity providers associated with the cluster. The following are the states that are returned.

          UPDATE_IN_PROGRESS

          The available capacity providers for the cluster are updating.

          UPDATE_COMPLETE

          The capacity providers have successfully updated.

          UPDATE_FAILED

          The capacity provider updates failed.

        • serviceConnectDefaults — (map)

          Use this parameter to set a default Service Connect namespace. After you set a default Service Connect namespace, any new services with Service Connect turned on that are created in the cluster are added as client services in the namespace. This setting only applies to new services that set the enabled parameter to true in the ServiceConnectConfiguration. You can set the namespace of each service individually in the ServiceConnectConfiguration to override this default parameter.

          Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

          • namespace — (String)

            The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace. When you create a service and don't specify a Service Connect configuration, this namespace is used.

      • failures — (Array<map>)

        Any failures associated with the call.

        • arn — (String)

          The Amazon Resource Name (ARN) of the failed resource.

        • reason — (String)

          The reason for the failure.

        • detail — (String)

          The details of the failure.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

});

Parameters:

  • params (Object) (defaults to: {})
    • cluster — (String)

      The short name or full Amazon Resource Name (ARN) of the cluster that hosts the container instances to describe. If you do not specify a cluster, the default cluster is assumed.

For port resource types, this parameter describes the ports that were reserved by the Amazon ECS container agent (at instance registration time) and any task containers that have reserved port mappings on the host (with the host or bridge network mode). Any port that's not specified here is available for new tasks.

          • name — (String)

            The name of the resource, such as CPU, MEMORY, PORTS, PORTS_UDP, or a user-defined resource.

          If your account has opted in to the awsvpcTrunking account setting, then any newly registered container instance will transition to a REGISTERING status while the trunk elastic network interface is provisioned for the instance. If the registration fails, the instance will transition to a REGISTRATION_FAILED status. You can describe the container instance and see the reason for failure in the statusReason parameter. Once the container instance is terminated, the instance transitions to a DEREGISTERING status while the trunk elastic network interface is deprovisioned. The instance then transitions to an INACTIVE status.

          The ACTIVE status indicates that the container instance can accept tasks. The DRAINING indicates that new tasks aren't placed on the container instance and any service tasks running on the container instance are removed if possible. For more information, see Container instance draining in the Amazon Elastic Container Service Developer Guide.

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • services — (Array<map>)

        The list of services described.

        • serviceArn — (String)

          The ARN that identifies the service. For more information about the ARN format, see Amazon Resource Name (ARN) in the Amazon ECS Developer Guide.

        • serviceName — (String)

          The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster. However, you can have similarly named services in multiple clusters within a Region or across multiple Regions.

        • clusterArn — (String)

          The Amazon Resource Name (ARN) of the cluster that hosts the service.

        • loadBalancers — (Array<map>)

          A list of Elastic Load Balancing load balancer objects. It contains the load balancer name, the container name, and the container port to access from the load balancer. The container name is as it appears in a container definition.

          • targetGroupArn — (String)

            The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

            A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

            For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

            For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.

            If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance. Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

          • loadBalancerName — (String)

            The name of the load balancer to associate with the Amazon ECS service or task set.

            If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

          • containerName — (String)

            The name of the container (as it appears in a container definition) to associate with the load balancer.

            You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

          • containerPort — (Integer)

            The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

        • serviceRegistries — (Array<map>)

          The details for the service discovery registries to assign to this service. For more information, see Service Discovery.

          • registryArn — (String)

            The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.

          • port — (Integer)

            The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.

          • containerName — (String)

            The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

          • containerPort — (Integer)

            The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

        • status — (String)

          The status of the service. The valid values are ACTIVE, DRAINING, or INACTIVE.

        • desiredCount — (Integer)

          The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService.

        • runningCount — (Integer)

          The number of tasks in the cluster that are in the RUNNING state.

        • pendingCount — (Integer)

          The number of tasks in the cluster that are in the PENDING state.

        • launchType — (String)

          The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.

          Possible values include:
          • "EC2"
          • "FARGATE"
          • "EXTERNAL"
        • capacityProviderStrategy — (Array<map>)

          The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.

          • capacityProviderrequired — (String)

            The short name of the capacity provider.

          • weight — (Integer)

            The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

            If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

            An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

          • base — (Integer)

            The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

        • platformVersion — (String)

          The platform version to run your service on. A platform version is only specified for tasks that are hosted on Fargate. If one isn't specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.

        • platformFamily — (String)

          The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.

          All tasks that run as part of this service must use the same platformFamily value as the service (for example, LINUX).

        • taskDefinition — (String)

          The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.

        • deploymentConfiguration — (map)

          Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.

          • deploymentCircuitBreaker — (map)
            Note: The deployment circuit breaker can only be used for services using the rolling update (ECS) deployment type.

            The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide

            • enablerequired — (Boolean)

              Determines whether to use the deployment circuit breaker logic for the service.

            • rollbackrequired — (Boolean)

              Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

          • maximumPercent — (Integer)

            If a service is using the rolling update (ECS) deployment type, the maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.

            If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.

          • minimumHealthyPercent — (Integer)

            If a service is using the rolling update (ECS) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.

            For services that do not use a load balancer, the following should be noted:

            • A service is considered healthy if all essential containers within the tasks in the service pass their health checks.

            • If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.

            • If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.

            For services that do use a load balancer, the following should be noted:

            • If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

            • If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

            The default value for a replica service for minimumHealthyPercent is 100%. The default minimumHealthyPercent value for a service using the DAEMON service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.

            The minimum number of healthy tasks during a deployment is the desiredCount multiplied by the minimumHealthyPercent/100, rounded up to the nearest integer value.

            If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

          • alarms — (map)

            Information about the CloudWatch alarms.

            • alarmNamesrequired — (Array<String>)

              One or more CloudWatch alarm names. Use a "," to separate the alarms.

            • enablerequired — (Boolean)

              Determines whether to use the CloudWatch alarm option in the service deployment process.

            • rollbackrequired — (Boolean)

              Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is used, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

        • taskSets — (Array<map>)

          Information about a set of Amazon ECS tasks in either an CodeDeploy or an EXTERNAL deployment. An Amazon ECS task set includes details such as the desired number of tasks, how many tasks are running, and whether the task set serves production traffic.

          • startedBy — (String)

            The tag specified when a task set is started. If an CodeDeploy deployment created the task set, the startedBy parameter is CODE_DEPLOY. If an external deployment created the task set, the startedBy field isn't used.

          • externalId — (String)

            The external ID associated with the task set.

            If an CodeDeploy deployment created a task set, the externalId parameter contains the CodeDeploy deployment ID.

            If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute.

          • status — (String)

            The status of the task set. The following describes each state.

            PRIMARY

            The task set is serving production traffic.

            ACTIVE

            The task set isn't serving production traffic.

            DRAINING

            The tasks in the task set are being stopped, and their corresponding targets are being deregistered from their target group.

          • taskDefinition — (String)

            The task definition that the task set is using.

          • computedDesiredCount — (Integer)

            The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.

          • pendingCount — (Integer)

            The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it's restarted after being in the STOPPED state.

          • runningCount — (Integer)

            The number of tasks in the task set that are in the RUNNING status during a deployment. A task in the RUNNING state is running and ready for use.

          • createdAt — (Date)

            The Unix timestamp for the time when the task set was created.

          • updatedAt — (Date)

            The Unix timestamp for the time when the task set was last updated.

          • launchType — (String)

            The launch type the tasks in the task set are using. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

            Possible values include:
            • "EC2"
            • "FARGATE"
            • "EXTERNAL"
          • capacityProviderStrategy — (Array<map>)

            • capacityProviderrequired — (String)

              The short name of the capacity provider.

            • weight — (Integer)

              The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

              If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

              An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

            • base — (Integer)

              The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

          • platformVersion — (String)

            The Fargate platform version where the tasks in the task set are running. A platform version is only specified for tasks run on Fargate. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

          • platformFamily — (String)

            The operating system that your tasks in the set are running on. A platform family is specified only for tasks that use the Fargate launch type.

              • securityGroups — (Array<String>)

                The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration.

                Note: All specified security groups must be from the same VPC.
              • assignPublicIp — (String)

                Whether the task's elastic network interface receives a public IP address. The default value is DISABLED.

                Possible values include:
                • "ENABLED"
                • "DISABLED"
          • loadBalancers — (Array<map>)

            • targetGroupArn — (String)

              The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

              A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

              For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

              For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.

              If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance. Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

            • loadBalancerName — (String)

              The name of the load balancer to associate with the Amazon ECS service or task set.

              If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

            • containerName — (String)

              The name of the container (as it appears in a container definition) to associate with the load balancer.

              You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

            • containerPort — (Integer)

              The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

          • serviceRegistries — (Array<map>)

If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

            • containerPort — (Integer)

              The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

          • scale — (map)

            A floating-point percentage of your desired number of tasks to place and keep running in the task set.

            • value — (Float)

          • tags — (Array<map>)

            The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value. You define both.

            The following basic restrictions apply to tags:

            • Maximum number of tags per resource - 50

            • For each resource, each tag key must be unique, and each tag key can have only one value.

            • Maximum key length - 128 Unicode characters in UTF-8

            • Maximum value length - 256 Unicode characters in UTF-8

            • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

            • Tag keys and values are case-sensitive.

            • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

            • key — (String)

              One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

            • value — (String)

              The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

        • deployments — (Array<map>)

          The current state of deployments for the service.

          • id — (String)

            The ID of the deployment.

          • status — (String)

            The status of the deployment. The following describes each state.

            PRIMARY

            The most recent deployment of a service.

            ACTIVE

            A service deployment that still has running tasks, but are in the process of being replaced with a new PRIMARY deployment.

            INACTIVE

            A deployment that has been completely replaced.

          • taskDefinition — (String)

            The most recent task definition that was specified for the tasks in the service to use.

          • desiredCount — (Integer)

            The most recent desired count of tasks that was specified for the service to deploy or maintain.

          • pendingCount — (Integer)

            The number of tasks in the deployment that are in the PENDING status.

          • runningCount — (Integer)

            The number of tasks in the deployment that are in the RUNNING status.

          • failedTasks — (Integer)

            The number of consecutively failed tasks in the deployment. A task is considered a failure if the service scheduler can't launch the task, the task doesn't transition to a RUNNING state, or if it fails any of its defined health checks and is stopped.

            Note: Once a service deployment has one or more successfully running tasks, the failed task count resets to zero and stops being evaluated.
          • createdAt — (Date)

            The Unix timestamp for the time when the service deployment was created.

          • updatedAt — (Date)

            The Unix timestamp for the time when the service deployment was last updated.

          • capacityProviderStrategy — (Array<map>)

            The capacity provider strategy that the deployment is using.

            • capacityProviderrequired — (String)

              The short name of the capacity provider.

            • weight — (Integer)

              The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

              If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

              An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

            • base — (Integer)

              The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

          • launchType — (String)

            The rollout state of the deployment. When a service deployment is started, it begins in an IN_PROGRESS state. When the service reaches a steady state, the deployment transitions to a COMPLETED state. If the service fails to reach a steady state and circuit breaker is turned on, the deployment transitions to a FAILED state. A deployment in FAILED state doesn't launch any new tasks. For more information, see DeploymentCircuitBreaker.

            Possible values include:
            • "COMPLETED"

            The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.

            Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

            • enabledrequired — (Boolean)

              Specifies whether to use Service Connect with this service.

            • namespace — (String)

              The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace for use with Service Connect. The namespace must be in the same Amazon Web Services Region as the Amazon ECS service and cluster. The type of namespace doesn't affect Service Connect. For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide.

            • services — (Array<map>)

              The list of Service Connect service objects. These are names and aliases (also known as endpoints) that are used by other Amazon ECS services to connect to this service.

              This field is not required for a "client" Amazon ECS service that's a member of a namespace only to connect to other services within the namespace. An example of this would be a frontend application that accepts incoming requests from either a load balancer that's attached to the service or by other means.

              An object selects a port from the task definition, assigns a name for the Cloud Map service, and a list of aliases (endpoints) and ports for client applications to refer to this service.

              • portNamerequired — (String)

                The portName must match the name of one of the portMappings from all the containers in the task definition of this Amazon ECS service.

              • discoveryName — (String)

                The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

                If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

              • clientAliases — (Array<map>)

                The list of client aliases for this Service Connect service. You use these to assign names that can be used by client applications. The maximum number of client aliases that you can have in this list is 1.

                Each alias ("endpoint") is a fully-qualified name and port number that other Amazon ECS tasks ("clients") can use to connect to this service.

                Each name and port mapping must be unique within the namespace.

                For each ServiceConnectService, you must provide at least one clientAlias with one port.

                • portrequired — (Integer)

                  The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.

                  To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

                • dnsName — (String)

                  The dnsName is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.

                  If this parameter isn't specified, the default value of discoveryName.namespace is used. If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

                  To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are database, db, or the lowercase name of a database, such as mysql or redis. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

              • ingressPortOverride — (Integer)

                The port number for the Service Connect proxy to listen on.

                Use the value of this field to bypass the proxy for traffic on the port number specified in the named portMapping in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.

                In awsvpc mode and Fargate, the default value is the container port number. The container port number is in the portMapping in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.

              • timeout — (map)

                A reference to an object that represents the configured timeouts for Service Connect.

                • idleTimeoutSeconds — (Integer)

                  The amount of time in seconds a connection will stay active while idle. A value of 0 can be set to disable idleTimeout.

                  The idleTimeout default for HTTP/HTTP2/GRPC is 5 minutes.

                  The idleTimeout default for TCP is 1 hour.

                • perRequestTimeoutSeconds — (Integer)

                  The amount of time waiting for the upstream to respond with a complete response per request. A value of 0 can be set to disable perRequestTimeout. perRequestTimeout can only be set if Service Connect appProtocol isn't TCP. Only idleTimeout is allowed for TCP appProtocol.

              • tls — (map)

                A reference to an object that represents a Transport Layer Security (TLS) configuration.

            • logConfiguration — (map)

              The log configuration for the container. This parameter maps to LogConfig in the docker conainer create command and the --log-driver option to docker run.

              By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition.

              Understand the following when specifying a log configuration for your containers.

              • Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent.

                For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

                For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald,syslog, splunk, and awsfirelens.

              • This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.

              • For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide.

              • For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

              • logDriverrequired — (String)

                The log driver to use for the container.

                For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

                For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, syslog, splunk, and awsfirelens.

                For more information about using the awslogs log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.

                For more information about using the awsfirelens log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.

                Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
                Possible values include:
                • "json-file"
                • "syslog"
                • "journald"
                • "gelf"
                • "fluentd"
                • "awslogs"
                • "splunk"
                • "awsfirelens"
              • options — (map<String>)

                The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

              • secretOptions — (Array<map>)

                The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide.

                  The name of the secret.

                • valueFromrequired — (String)

                  The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.

                  For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide.

                  Note: If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
          • serviceConnectResources — (Array<map>)

            The list of Service Connect resources that are associated with this deployment. Each list entry maps a discovery name to a Cloud Map service name.

              The discovery name of this Service Connect resource.

              The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

              If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

            • discoveryArn — (String)

              The Amazon Resource Name (ARN) for the namespace in Cloud Map that matches the discovery name for this Service Connect resource. You can use this ARN in other integrations with Cloud Map. However, Service Connect can't ensure connectivity outside of Amazon ECS.

          • volumeConfigurations — (Array<map>)

            The details of the volume that was configuredAtLaunch. You can configure different settings like the size, throughput, volumeType, and ecryption in ServiceManagedEBSVolumeConfiguration. The name of the volume must match the name from the task definition.

            • namerequired — (String)

              The name of the volume. This value must match the volume name from the Volume object in the task definition.

            • managedEBSVolume — (map)

              The configuration for the Amazon EBS volume that Amazon ECS creates and manages on your behalf. These settings are used to create each Amazon EBS volume, with one volume created for each task in the service. The Amazon EBS volumes are visible in your account in the Amazon EC2 console once they are created.

              • encrypted — (Boolean)

                Indicates whether the volume should be encrypted. If no value is specified, encryption is turned on by default. This parameter maps 1:1 with the Encrypted parameter of the CreateVolume API in the Amazon EC2 API Reference.

              • kmsKeyId — (String)

                The Amazon Resource Name (ARN) identifier of the Amazon Web Services Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no Amazon Web Services Key Management Service key is specified, the default Amazon Web Services managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the KmsKeyId parameter of the CreateVolume API in the Amazon EC2 API Reference.

                Amazon Web Services authenticates the Amazon Web Services Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails.

              • volumeType — (String)

                The volume type. This parameter maps 1:1 with the VolumeType parameter of the CreateVolume API in the Amazon EC2 API Reference. For more information, see Amazon EBS volume types in the Amazon EC2 User Guide.

                The following are the supported volume types.

                • General Purpose SSD: gp2|gp3

                • Provisioned IOPS SSD: io1|io2

                • Throughput Optimized HDD: st1

                • Cold HDD: sc1

              • sizeInGiB — (Integer)

                The size of the volume in GiB. You must specify either a volume size or a snapshot ID. If you specify a snapshot ID, the snapshot size is used for the volume size by default. You can optionally specify a volume size greater than or equal to the snapshot size. This parameter maps 1:1 with the Size parameter of the CreateVolume API in the Amazon EC2 API Reference.

                The following are the supported volume size values for each volume type.

                • gp2 and gp3: 1-16,384

                • io1 and io2: 4-16,384

                • st1 and sc1: 125-16,384

              • snapshotId — (String)

                The snapshot that Amazon ECS uses to create the volume. You must specify either a snapshot ID or a volume size. This parameter maps 1:1 with the SnapshotId parameter of the CreateVolume API in the Amazon EC2 API Reference.

              • iops — (Integer)

                The number of I/O operations per second (IOPS). For gp3, io1, and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.

                The following are the supported values for each volume type.

                • gp3: 3,000 - 16,000 IOPS

                • io1: 100 - 64,000 IOPS

                • io2: 100 - 256,000 IOPS

                This parameter is required for io1 and io2 volume types. The default for gp3 volumes is 3,000 IOPS. This parameter is not supported for st1, sc1, or standard volume types.

                This parameter maps 1:1 with the Iops parameter of the CreateVolume API in the Amazon EC2 API Reference.

              • throughput — (Integer)

                The throughput to provision for a volume, in MiB/s, with a maximum of 1,000 MiB/s. This parameter maps 1:1 with the Throughput parameter of the CreateVolume API in the Amazon EC2 API Reference.

                This parameter is only supported for the gp3 volume type.

              • tagSpecifications — (Array<map>)

                The tags to apply to the volume. Amazon ECS applies service-managed tags by default. This parameter maps 1:1 with the TagSpecifications.N parameter of the CreateVolume API in the Amazon EC2 API Reference.

                • resourceTyperequired — (String)

                  The type of volume resource.

                  Possible values include:
                  • "volume"
                • tags — (Array<map>)

                  The tags applied to this Amazon EBS volume. AmazonECSCreated and AmazonECSManaged are reserved tags that can't be used.

                  • key — (String)

                    One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

                  • value — (String)

                    The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

                • propagateTags — (String)

                  Determines whether to propagate the tags from the task definition to 
the Amazon EBS volume. Tags can only propagate to a SERVICE specified in 
ServiceVolumeConfiguration. If no value is specified, the tags aren't 
propagated.

                  Possible values include:
                  • "TASK_DEFINITION"
                  • "SERVICE"

              • roleArnrequired — (String)

                The ARN of the IAM role to associate with this volume. This is the Amazon ECS infrastructure IAM role that is used to manage your Amazon Web Services infrastructure. We recommend using the Amazon ECS-managed AmazonECSInfrastructureRolePolicyForVolumes IAM policy with this role. For more information, see Amazon ECS infrastructure IAM role in the Amazon ECS Developer Guide.

              • filesystemType — (String)

                The Linux filesystem type for the volume. For volumes created from a snapshot, you must specify the same filesystem type that the volume was using when the snapshot was created. If there is a filesystem type mismatch, the task will fail to start.

                The available filesystem types are
 ext3, ext4, and xfs. If no value is specified, the xfs filesystem type is used by default.

                Possible values include:
                • "ext3"
                • "ext4"
                • "xfs"
          • fargateEphemeralStorage — (map)

            The Fargate ephemeral storage settings for the deployment.

            • kmsKeyId — (String)

              Specify an Key Management Service key ID to encrypt the ephemeral storage for deployment.

        • roleArn — (String)

            The ID string for the event.

          • createdAt — (Date)

            The Unix timestamp for the time when the event was triggered.

          • message — (String)

            The event message.

        • createdAt — (Date)

          The Unix timestamp for the time when the service was created.

        • placementConstraints — (Array<map>)

          The placement constraints for the tasks in the service.

          • type — (String)

            The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.

            Possible values include:
            • "distinctInstance"
            • "memberOf"
          • expression — (String)

            A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters.

        • placementStrategy — (Array<map>)

          The placement strategy that determines how tasks for the service are placed.

          • type — (String)

            The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that's specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.

            Possible values include:
            • "random"
            • "spread"
            • "binpack"
          • field — (String)

            The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host, which has the same effect), or any platform or custom attribute that's applied to a container instance, such as attribute:ecs.availability-zone. For the binpack placement strategy, valid values are cpu and memory. For the random placement strategy, this field is not used.

        • networkConfiguration — (map)

          The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.

          • awsvpcConfiguration — (map)

            The VPC subnets and security groups that are associated with a task.

            Note: All specified subnets and security groups must be from the same VPC.
            • subnetsrequired — (Array<String>)

              The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per awsvpcConfiguration.

              Note: All specified subnets must be from the same VPC.
            • securityGroups — (Array<String>)

              The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration.

              Note: All specified security groups must be from the same VPC.
            • assignPublicIp — (String)

              Whether the task's elastic network interface receives a public IP address. The default value is DISABLED.

              Possible values include:
              • "ENABLED"
              • "DISABLED"
        • healthCheckGracePeriodSeconds — (Integer)

          The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started.

        • schedulingStrategy — (String)

          The scheduling strategy to use for the service. For more information, see Services.

          There are two service scheduler strategies available.

          • REPLICA-The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions.

          • DAEMON-The daemon scheduling strategy deploys exactly one task on each active container instance. This task meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It stop tasks that don't meet the placement constraints.

            Note: Fargate tasks don't support the DAEMON scheduling strategy.
          Possible values include:
          • "REPLICA"
          • "DAEMON"
        • deploymentController — (map)

          The deployment controller type the service is using.

          • typerequired — (String)

            The deployment controller type to use.

            There are three deployment controller types available:

            ECS

            The rolling update (ECS) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration.

            CODE_DEPLOY

            The blue/green (CODE_DEPLOY) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.

            EXTERNAL

            The external (EXTERNAL) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.

            Possible values include:
            • "ECS"
            • "CODE_DEPLOY"
            • "EXTERNAL"
        • tags — (Array<map>)

          The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value. You define bot the key and value.

          The following basic restrictions apply to tags:

          • Maximum number of tags per resource - 50

          • For each resource, each tag key must be unique, and each tag key can have only one value.

          • Maximum key length - 128 Unicode characters in UTF-8

          • Maximum value length - 256 Unicode characters in UTF-8

          • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

          • Tag keys and values are case-sensitive.

          • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

          • key — (String)

            One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

          • value — (String)

            The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

        • createdBy — (String)

          The principal that created the service.

        • enableECSManagedTags — (Boolean)

          Determines whether to use Amazon ECS managed tags for the tasks in the service. For more information, see Tagging Your Amazon ECS Resources in the Amazon Elastic Container Service Developer Guide.

        • propagateTags — (String)

          Determines whether to propagate the tags from the task definition or the service to the task. If no value is specified, the tags aren't propagated.

          Possible values include:
          • "TASK_DEFINITION"
          • "SERVICE"
          • "NONE"
        • enableExecuteCommand — (Boolean)

          Determines whether the execute command functionality is turned on for the service. If true, the execute command functionality is turned on for all containers in tasks as part of the service.

      • failures — (Array<map>)

        Any failures associated with the call.

        • arn — (String)

          The Amazon Resource Name (ARN) of the failed resource.

        • reason — (String)

          The reason for the failure.

        • detail — (String)

          The details of the failure.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

Waiter Resource States:

describeTaskDefinition(params = {}, callback) ⇒ AWS.Request

Describes a task definition. You can specify a family and revision to find information about a specific task definition, or you can simply specify the family to find the latest ACTIVE revision in that family.

Note: You can only describe INACTIVE task definitions while an active task or service references them.

Calling the describeTaskDefinition operation

var params = {
  taskDefinition: 'STRING_VALUE', /* required */
  include: [
    TAGS,
    /* more items */
  ]
};
ecs.describeTaskDefinition(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • taskDefinition — (String)

      The family for the latest ACTIVE revision, family and revision (family:revision) for a specific revision in the family, or full Amazon Resource Name (ARN) of the task definition to describe.

    • include — (Array<String>)

      Determines whether to see the resource tags for the task definition. If TAGS is specified, the tags are included in the response. If this field is omitted, tags aren't included in the response.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • taskDefinition — (map)

        The full task definition description.

        • taskDefinitionArn — (String)

          The full Amazon Resource Name (ARN) of the task definition.

        • containerDefinitions — (Array<map>)

          A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.

          • name — (String)

            The name of a container. If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in tthe docker conainer create command and the --name option to docker run.

          • image — (String)

            The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the docker conainer create command and the IMAGE parameter of docker run.

            • When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.

            • Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag or registry/repository@digest. For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE.

            • Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo).

            • Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent).

            • Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu).

          • repositoryCredentials — (map)

            The private repository authentication credentials to use.

            • credentialsParameterrequired — (String)

              The Amazon Resource Name (ARN) of the secret containing the private repository credentials.

              Note: When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
          • cpu — (Integer)

            The number of cpu units reserved for the container. This parameter maps to CpuShares in the docker conainer create commandand the --cpu-shares option to docker run.

            This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.

            Note: You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.

            Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.

            On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. The minimum valid CPU share value that the Linux kernel allows is 2, and the maximum valid CPU share value that the Linux kernel allows is 262144. However, the CPU parameter isn't required, and you can use CPU values below 2 or above 262144 in your container definitions. For CPU values below 2 (including null) or above 262144, the behavior varies based on your Amazon ECS container agent version:

            • Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.

            • Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.

            • Agent versions greater than or equal to 1.84.0: CPU values greater than 256 vCPU are passed to Docker as 256, which is equivalent to 262144 CPU shares.

            On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0, which Windows interprets as 1% of one CPU.

          • memory — (Integer)

            The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in thethe docker conainer create command and the --memory option to docker run.

            If using the Fargate launch type, this parameter is optional.

            If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.

            The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.

            The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.

          • memoryReservation — (Integer)

            The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the the docker conainer create command and the --memory-reservation option to docker run.

            If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.

            For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.

            The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.

            The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.

          • links — (Array<String>)

            The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge. The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.. This parameter maps to Links in the docker conainer create command and the --link option to docker run.

            Note: This parameter is not supported for Windows containers.

            Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.

          • portMappings — (Array<map>)

            The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.

            For task definitions that use the awsvpc network mode, only specify the containerPort. The hostPort can be left blank or it must be the same value as the containerPort.

            Port mappings on Windows use the NetNAT gateway address rather than localhost. There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.

            This parameter maps to PortBindings in the the docker conainer create command and the --publish option to docker run. If the network mode of a task definition is set to none, then you can't specify port mappings. If the network mode of a task definition is set to host, then host ports must either be undefined or they must match the container port in the port mapping.

            Note: After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.
            • containerPort — (Integer)

              The port number on the container that's bound to the user-specified or automatically assigned host port.

              If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort.

              If you use containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort. Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.

            • hostPort — (Integer)

              The port number on the container instance to reserve for your container.

              If you specify a containerPortRange, leave this field empty and the value of the hostPort is set as follows:

              • For containers in a task with the awsvpc network mode, the hostPort is set to the same value as the containerPort. This is a static mapping strategy.

              • For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.

              If you use containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort.

              If you use containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.

              The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.

              The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.

            • protocol — (String)

              The protocol used for the port mapping. Valid values are tcp and udp. The default is tcp. protocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.

              Possible values include:
              • "tcp"
              • "udp"
            • name — (String)

              The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the serviceConnectConfiguration of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

              For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

            • appProtocol — (String)

              The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.

              If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.

              appProtocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.

              Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

              Possible values include:
              • "http"
              • "http2"
              • "grpc"
            • containerPortRange — (String)

              The port number range on the container that's bound to the dynamically mapped host port range.

              The following rules apply when you specify a containerPortRange:

              • You must use either the bridge network mode or the awsvpc network mode.

              • This parameter is available for both the EC2 and Fargate launch types.

              • This parameter is available for both the Linux and Windows operating systems.

              • The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package

              • You can specify a maximum of 100 port ranges per container.

              • You do not specify a hostPortRange. The value of the hostPortRange is set as follows:

                • For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange. This is a static mapping strategy.

                • For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.

              • The containerPortRange valid values are between 1 and 65535.

              • A port can only be included in one port mapping per container.

              • You cannot specify overlapping port ranges.

              • The first port in the range must be less than last port in the range.

              • Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.

                For more information, see Issue #11185 on the Github website.

                For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.

              You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.

          • essential — (Boolean)

            If the essential parameter of a container is marked as true, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.

            All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.

          • restartPolicy — (map)

            The restart policy for a container. When you set up a restart policy, Amazon ECS can restart the container without needing to replace the task. For more information, see Restart individual containers in Amazon ECS tasks with container restart policies in the Amazon Elastic Container Service Developer Guide.

            • enabledrequired — (Boolean)

              Specifies whether a restart policy is enabled for the container.

            • ignoredExitCodes — (Array<Integer>)

              A list of exit codes that Amazon ECS will ignore and not attempt a restart on. You can specify a maximum of 50 container exit codes. By default, Amazon ECS does not ignore any exit codes.

            • restartAttemptPeriod — (Integer)

              A period of time (in seconds) that the container must run for before a restart can be attempted. A container can be restarted only once every restartAttemptPeriod seconds. If a container isn't able to run for this time period and exits early, it will not be restarted. You can set a minimum restartAttemptPeriod of 60 seconds and a maximum restartAttemptPeriod of 1800 seconds. By default, a container must run for 300 seconds before it can be restarted.

          • entryPoint — (Array<String>)

            Early versions of the Amazon ECS container agent don't properly handle entryPoint parameters. If you have problems using entryPoint, update your container agent or enter your commands and arguments as command array items instead.

            The entry point that's passed to the container. This parameter maps to Entrypoint in tthe docker conainer create command and the --entrypoint option to docker run.

          • command — (Array<String>)

            The command that's passed to the container. This parameter maps to Cmd in the docker conainer create command and the COMMAND parameter to docker run. If there are multiple arguments, each argument is a separated string in the array.

          • environment — (Array<map>)

            The environment variables to pass to a container. This parameter maps to Env in the docker conainer create command and the --env option to docker run.

            We don't recommend that you use plaintext environment variables for sensitive information, such as credential data.

            • name — (String)

              The name of the key-value pair. For environment variables, this is the name of the environment variable.

            • value — (String)

              The value of the key-value pair. For environment variables, this is the value of the environment variable.

          • environmentFiles — (Array<map>)

            A list of files containing the environment variables to pass to a container. This parameter maps to the --env-file option to docker run.

            You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file contains an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored.

            If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide.

            • valuerequired — (String)

              The Amazon Resource Name (ARN) of the Amazon S3 object containing the environment variable file.

            • typerequired — (String)

              The file type to use. Environment files are objects in Amazon S3. The only supported value is s3.

              Possible values include:
              • "s3"
          • mountPoints — (Array<map>)

            The mount points for data volumes in your container.

            This parameter maps to Volumes in the the docker conainer create command and the --volume option to docker run.

            Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives.

            • sourceVolume — (String)

              The name of the volume to mount. Must be a volume name referenced in the name parameter of task definition volume.

            • containerPath — (String)

              The path on the container to mount the host volume at.

            • readOnly — (Boolean)

              If this value is true, the container has read-only access to the volume. If this value is false, then the container can write to the volume. The default value is false.

          • volumesFrom — (Array<map>)

            Data volumes to mount from another container. This parameter maps to VolumesFrom in tthe docker conainer create command and the --volumes-from option to docker run.

            • sourceContainer — (String)

              The name of another container within the same task definition to mount volumes from.

            • readOnly — (Boolean)

              If this value is true, the container has read-only access to the volume. If this value is false, then the container can write to the volume. The default value is false.

          • linuxParameters — (map)

            Linux-specific modifications that are applied to the container, such as Linux kernel capabilities. For more information see KernelCapabilities.

            Note: This parameter is not supported for Windows containers.
            • capabilities — (map)

              The Linux capabilities for the container that are added to or dropped from the default configuration provided by Docker.

              Note: For tasks that use the Fargate launch type, capabilities is supported for all platform versions but the add parameter is only supported if using platform version 1.4.0 or later.
              • add — (Array<String>)

                The Linux capabilities for the container that have been added to the default configuration provided by Docker. This parameter maps to CapAdd in the docker conainer create command and the --cap-add option to docker run.

                Note: Tasks launched on Fargate only support adding the SYS_PTRACE kernel capability.

                Valid values: "ALL" | "AUDIT_CONTROL" | "AUDIT_WRITE" | "BLOCK_SUSPEND" | "CHOWN" | "DAC_OVERRIDE" | "DAC_READ_SEARCH" | "FOWNER" | "FSETID" | "IPC_LOCK" | "IPC_OWNER" | "KILL" | "LEASE" | "LINUX_IMMUTABLE" | "MAC_ADMIN" | "MAC_OVERRIDE" | "MKNOD" | "NET_ADMIN" | "NET_BIND_SERVICE" | "NET_BROADCAST" | "NET_RAW" | "SETFCAP" | "SETGID" | "SETPCAP" | "SETUID" | "SYS_ADMIN" | "SYS_BOOT" | "SYS_CHROOT" | "SYS_MODULE" | "SYS_NICE" | "SYS_PACCT" | "SYS_PTRACE" | "SYS_RAWIO" | "SYS_RESOURCE" | "SYS_TIME" | "SYS_TTY_CONFIG" | "SYSLOG" | "WAKE_ALARM"

              • drop — (Array<String>)

                The Linux capabilities for the container that have been removed from the default configuration provided by Docker. This parameter maps to CapDrop in the docker conainer create command and the --cap-drop option to docker run.

                Valid values: "ALL" | "AUDIT_CONTROL" | "AUDIT_WRITE" | "BLOCK_SUSPEND" | "CHOWN" | "DAC_OVERRIDE" | "DAC_READ_SEARCH" | "FOWNER" | "FSETID" | "IPC_LOCK" | "IPC_OWNER" | "KILL" | "LEASE" | "LINUX_IMMUTABLE" | "MAC_ADMIN" | "MAC_OVERRIDE" | "MKNOD" | "NET_ADMIN" | "NET_BIND_SERVICE" | "NET_BROADCAST" | "NET_RAW" | "SETFCAP" | "SETGID" | "SETPCAP" | "SETUID" | "SYS_ADMIN" | "SYS_BOOT" | "SYS_CHROOT" | "SYS_MODULE" | "SYS_NICE" | "SYS_PACCT" | "SYS_PTRACE" | "SYS_RAWIO" | "SYS_RESOURCE" | "SYS_TIME" | "SYS_TTY_CONFIG" | "SYSLOG" | "WAKE_ALARM"

            • devices — (Array<map>)

              Any host devices to expose to the container. This parameter maps to Devices in tthe docker conainer create command and the --device option to docker run.

              Note: If you're using tasks that use the Fargate launch type, the devices parameter isn't supported.
              • hostPathrequired — (String)

                The path for the device on the host container instance.

              • containerPath — (String)

                The path inside the container at which to expose the host device.

              • permissions — (Array<String>)

                The explicit permissions to provide to the container for the device. By default, the container has permissions for read, write, and mknod for the device.

            • initProcessEnabled — (Boolean)

              Run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

            • sharedMemorySize — (Integer)

              The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run.

              Note: If you are using tasks that use the Fargate launch type, the sharedMemorySize parameter is not supported.
            • tmpfs — (Array<map>)

              The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run.

              Note: If you're using tasks that use the Fargate launch type, the tmpfs parameter isn't supported.
              • containerPathrequired — (String)

                The absolute file path where the tmpfs volume is to be mounted.

              • sizerequired — (Integer)

                The maximum size (in MiB) of the tmpfs volume.

              • mountOptions — (Array<String>)

                The list of tmpfs volume mount options.

                Valid values: "defaults" | "ro" | "rw" | "suid" | "nosuid" | "dev" | "nodev" | "exec" | "noexec" | "sync" | "async" | "dirsync" | "remount" | "mand" | "nomand" | "atime" | "noatime" | "diratime" | "nodiratime" | "bind" | "rbind" | "unbindable" | "runbindable" | "private" | "rprivate" | "shared" | "rshared" | "slave" | "rslave" | "relatime" | "norelatime" | "strictatime" | "nostrictatime" | "mode" | "uid" | "gid" | "nr_inodes" | "nr_blocks" | "mpol"

            • maxSwap — (Integer)

              The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value.

              If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.

              Note: If you're using tasks that use the Fargate launch type, the maxSwap parameter isn't supported. If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.
            • swappiness — (Integer)

              This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100. If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run.

              Note: If you're using tasks that use the Fargate launch type, the swappiness parameter isn't supported. If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.
          • secrets — (Array<map>)

            The secrets to pass to the container. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide.

            • namerequired — (String)

              The name of the secret.

            • valueFromrequired — (String)

              The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.

              For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide.

              Note: If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
          • dependsOn — (Array<map>)

            The dependencies defined for container startup and shutdown. A container can contain multiple dependencies on other containers in a task definition. When a dependency is defined for container startup, for container shutdown it is reversed.

            For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

            For tasks using the Fargate launch type, the task or service requires the following platforms:

            • Linux platform version 1.3.0 or later.

            • Windows platform version 1.0.0 or later.

            • containerNamerequired — (String)

              The name of a container.

            • conditionrequired — (String)

              The dependency condition of the container. The following are the available conditions and their behavior:

              • START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.

              • COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.

              • SUCCESS - This condition is the same as COMPLETE, but it also requires that the container exits with a zero status. This condition can't be set on an essential container.

              • HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.

              Possible values include:
              • "START"
              • "COMPLETE"
              • "SUCCESS"
              • "HEALTHY"
          • startTimeout — (Integer)

            Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE, SUCCESS, or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state.

            Note: When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it's enforced independently from this start timeout value.

            For tasks using the Fargate launch type, the task or service requires the following platforms:

            • Linux platform version 1.3.0 or later.

            • Windows platform version 1.0.0 or later.

            For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

            The valid values for Fargate are 2-120 seconds.

          • stopTimeout — (Integer)

            Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.

            For tasks using the Fargate launch type, the task or service requires the following platforms:

            • Linux platform version 1.3.0 or later.

            • Windows platform version 1.0.0 or later.

            The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.

            For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

            The valid values are 2-120 seconds.

          • hostname — (String)

            The hostname to use for your container. This parameter maps to Hostname in thethe docker conainer create command and the --hostname option to docker run.

          • user — (String)

            The user to use inside the container. This parameter maps to User in the docker conainer create command and the --user option to docker run.

            When running tasks using the host network mode, don't run containers using the root user (UID 0). We recommend using a non-root user for better security.

            You can specify the user using the following formats. If specifying a UID or GID, you must specify it as a positive integer.

            • user

            • user:group

            • uid

            • uid:gid

            • user:gid

            Note: This parameter is not supported for Windows containers.
          • workingDirectory — (String)

            The working directory to run commands inside the container in. This parameter maps to WorkingDir in the docker conainer create command and the --workdir option to docker run.

          • disableNetworking — (Boolean)

            When this parameter is true, networking is off within the container. This parameter maps to NetworkDisabled in the docker conainer create command.

            Note: This parameter is not supported for Windows containers.
          • privileged — (Boolean)

            When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root user). This parameter maps to Privileged in the the docker conainer create command and the --privileged option to docker run

            Note: This parameter is not supported for Windows containers or tasks run on Fargate.
          • readonlyRootFilesystem — (Boolean)

            When this parameter is true, the container is given read-only access to its root file system. This parameter maps to ReadonlyRootfs in the docker conainer create command and the --read-only option to docker run.

            Note: This parameter is not supported for Windows containers.
          • dnsServers — (Array<String>)

            A list of DNS servers that are presented to the container. This parameter maps to Dns in the the docker conainer create command and the --dns option to docker run.

          • extraHosts — (Array<map>)

            A list of hostnames and IP address mappings to append to the /etc/hosts file on the container. This parameter maps to ExtraHosts in the docker conainer create command and the --add-host option to docker run.

            Note: This parameter isn't supported for Windows containers or tasks that use the awsvpc network mode.
            • hostnamerequired — (String)

              The hostname to use in the /etc/hosts entry.

            • ipAddressrequired — (String)

              The IP address to use in the /etc/hosts entry.

          • dockerSecurityOptions — (Array<String>)

            A list of strings to provide custom configuration for multiple security systems. This field isn't valid for containers in tasks using the Fargate launch type.

            For Linux tasks on EC2, this parameter can be used to reference custom labels for SELinux and AppArmor multi-level security systems.

            For any tasks on EC2, this parameter can be used to reference a credential spec file that configures a container for Active Directory authentication. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers in the Amazon Elastic Container Service Developer Guide.

            This parameter maps to SecurityOpt in the docker conainer create command and the --security-opt option to docker run.

            Note: The Amazon ECS container agent running on a container instance must register with the ECS_SELINUX_CAPABLE=true or ECS_APPARMOR_CAPABLE=true environment variables before containers placed on that instance can use these security options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.

            Valid values: "no-new-privileges" | "apparmor:PROFILE" | "label:value" | "credentialspec:CredentialSpecFilePath"

          • interactive — (Boolean)

            When this parameter is true, you can deploy containerized applications that require stdin or a tty to be allocated. This parameter maps to OpenStdin in the docker conainer create command and the --interactive option to docker run.

          • pseudoTerminal — (Boolean)

            When this parameter is true, a TTY is allocated. This parameter maps to Tty in tthe docker conainer create command and the --tty option to docker run.

          • dockerLabels — (map<String>)

            A key/value map of labels to add to the container. This parameter maps to Labels in the docker conainer create command and the --label option to docker run. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

          • ulimits — (Array<map>)

            A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it overrides the default values set by Docker. This parameter maps to Ulimits in tthe docker conainer create command and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type.

            Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 65535 and the default hard limit is 65535.

            This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

            Note: This parameter is not supported for Windows containers.
            • namerequired — (String)

              The type of the ulimit.

              Possible values include:
              • "core"
              • "cpu"
              • "data"
              • "fsize"
              • "locks"
              • "memlock"
              • "msgqueue"

              • "rss"
              • "rtprio"
              • "rttime"
              • "sigpending"
              • "stack"
            • softLimitrequired — (Integer)

              The soft limit for the ulimit type.

            • hardLimitrequired — (Integer)

              The hard limit for the ulimit type.

          • logConfiguration — (map)

            The log configuration specification for the container.

            This parameter maps to LogConfig in the docker conainer create command and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options).

            Note: Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.

            This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

            Note: The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.
            • logDriverrequired — (String)

              The log driver to use for the container.

              For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

              For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, syslog, splunk, and awsfirelens.

              For more information about using the awslogs log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.

              For more information about using the awsfirelens log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.

              Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
              Possible values include:
              • "json-file"
              • "syslog"
              • "journald"
              • "gelf"
              • "fluentd"
              • "awslogs"
              • "splunk"
              • "awsfirelens"
            • options — (map<String>)

              The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

            • secretOptions — (Array<map>)

              The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide.

              • namerequired — (String)

                The name of the secret.

              • valueFromrequired — (String)

                The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.

                For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide.

                Note: If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
          • healthCheck — (map)

            The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the docker conainer create command and the HEALTHCHECK parameter of docker run.

            • commandrequired — (Array<String>)

              A string array representing the command that the container runs to determine if it is healthy. The string array must start with CMD to run the command arguments directly, or CMD-SHELL to run the command with the container's default shell.

              When you use the Amazon Web Services Management Console JSON panel, the Command Line Interface, or the APIs, enclose the list of commands in double quotes and brackets.

              [ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]

              You don't include the double quotes and brackets when you use the Amazon Web Services Management Console.

              CMD-SHELL, curl -f http://localhost/ || exit 1

              An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in tthe docker conainer create command

            • interval — (Integer)

              The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.

            • timeout — (Integer)

              The time period in seconds to wait for a health check to succeed before it is considered a failure. You may specify between 2 and 60 seconds. The default value is 5.

            • retries — (Integer)

              The number of times to retry a failed health check before the container is considered unhealthy. You may specify between 1 and 10 retries. The default value is 3.

            • startPeriod — (Integer)

              The optional grace period to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You can specify between 0 and 300 seconds. By default, the startPeriod is off.

              Note: If a health check succeeds within the startPeriod, then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
          • systemControls — (Array<map>)

            A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in tthe docker conainer create command and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.

            • namespace — (String)

              The namespaced kernel parameter to set a value for.

            • value — (String)

              The namespaced kernel parameter to set a value for.

              Valid IPC namespace values: "kernel.msgmax" | "kernel.msgmnb" | "kernel.msgmni" | "kernel.sem" | "kernel.shmall" | "kernel.shmmax" | "kernel.shmmni" | "kernel.shm_rmid_forced", and Sysctls that start with "fs.mqueue.*"

              Valid network namespace values: Sysctls that start with "net.*"

              All of these values are supported by Fargate.

          • resourceRequirements — (Array<map>)

            The type and amount of a resource to assign to a container. The only supported resource is a GPU.

            • valuerequired — (String)

              The value for the specified resource type.

              When the type is GPU, the value is the number of physical GPUs the Amazon ECS container agent reserves for the container. The number of GPUs that's reserved for all containers in a task can't exceed the number of available GPUs on the container instance that the task is launched on.

              When the type is InferenceAccelerator, the value matches the deviceName for an InferenceAccelerator specified in a task definition.

            • typerequired — (String)

              The type of resource to assign to a container.

              Possible values include:
              • "GPU"
              • "InferenceAccelerator"
          • firelensConfiguration — (map)

            The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide.

            • typerequired — (String)

              The log router to use. The valid values are fluentd or fluentbit.

              Possible values include:
              • "fluentd"
              • "fluentbit"
            • options — (map<String>)

              The options to use when configuring the log router. This field is optional and can be used to specify a custom configuration file or to add additional metadata, such as the task, task definition, cluster, and container instance details to the log event. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"}. For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide.

              Note: Tasks hosted on Fargate only support the file configuration file type.
          • credentialSpecs — (Array<String>)

            A list of ARNs in SSM or Amazon S3 to a credential spec (CredSpec) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of the dockerSecurityOptions. The maximum number of ARNs is 1.

            There are two formats for each ARN.

            credentialspecdomainless:MyARN

            You use credentialspecdomainless:MyARN to provide a CredSpec with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.

            Each task that runs on any container instance can join different domains.

            You can use this format without joining the container instance to a domain.

            credentialspec:MyARN

            You use credentialspec:MyARN to provide a CredSpec for a single domain.

            You must join the container instance to the domain before you start any tasks that use this task definition.

            In both formats, replace MyARN with the ARN in SSM or Amazon S3.

            If you provide a credentialspecdomainless:MyARN, the credspec must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.

        • family — (String)

          The name of a family that this task definition is registered to. Up to 255 characters are allowed. Letters (both uppercase and lowercase letters), numbers, hyphens (-), and underscores (_) are allowed.

          A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.

        • taskRoleArn — (String)

          The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

        • executionRoleArn — (String)

          The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

        • networkMode — (String)

          The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. If no network mode is specified, the default is bridge.

          For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.

          With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.

          When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.

          If the network mode is awsvpc, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

          If the network mode is host, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.

          Possible values include:
          • "bridge"
          • "host"
          • "awsvpc"
          • "none"
        • revision — (Integer)

          The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is 1. Each time that you register a new revision of a task definition in the same family, the revision value always increases by one. This is even if you deregistered previous revisions in this family.

        • volumes — (Array<map>)

          The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide.

          Note: The host and sourcePath parameters aren't supported for tasks run on Fargate.
          • name — (String)

            The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.

            When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task.

            For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition.

            When a volume is using the efsVolumeConfiguration, the name is required.

          • host — (map)

            This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.

            Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D::D:\, but not D:\my\path:C:\my\path or D::C:\my\path.

            • sourcePath — (String)

              When the host parameter is used, specify a sourcePath to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.

              If you're using the Fargate launch type, the sourcePath parameter is not supported.

          • dockerVolumeConfiguration — (map)

            This parameter is specified when you use Docker volumes.

            Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.

            The Elastic Inference accelerator type to use.

        • pidMode — (String)

          The process namespace to use for the containers in the task. The valid values are host or task. On Fargate for Linux containers, the only valid value is task. For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.

          If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance.

          If task is specified, all containers within the specified task share the same process namespace.

          If no value is specified, the default is a private namespace for each container.

          If the host PID mode is used, there's a heightened risk of undesired process namespace exposure.

          Note: This parameter is not supported for Windows containers.
          Note: This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.

          • "host"
          • "task"
        • ipcMode — (String)

          The IPC resource namespace to use for the containers in the task. The valid values are host, task, or none. If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance.

          If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose.

          If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide.

          • For tasks that use the host IPC mode, IPC namespace related systemControls are not supported.

          • For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task.

          Note: This parameter is not supported for Windows containers or tasks run on Fargate.

                • For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange. This is a static mapping strategy.

                • For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.

              • The containerPortRange valid values are between 1 and 65535.

              • A port can only be included in one port mapping per container.

              • You cannot specify overlapping port ranges.

              • The first port in the range must be less than last port in the range.

              • Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.

                For more information, see Issue #11185 on the Github website.

                For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.

              You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.

          • For each resource, each tag key must be unique, and each tag key can have only one value.

          • Maximum key length - 128 Unicode characters in UTF-8

          • Maximum value length - 256 Unicode characters in UTF-8

          • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

          • Tag keys and values are case-sensitive.

          • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

          • key — (String)

            One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

        • startedBy — (String)

          The tag specified when a task set is started. If an CodeDeploy deployment created the task set, the startedBy parameter is CODE_DEPLOY. If an external deployment created the task set, the startedBy field isn't used.

        • externalId — (String)

          The external ID associated with the task set.

          If an CodeDeploy deployment created a task set, the externalId parameter contains the CodeDeploy deployment ID.

          If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute.

        • status — (String)

          The status of the task set. The following describes each state.

          PRIMARY

          The task set is serving production traffic.

          ACTIVE

          The task set isn't serving production traffic.

          DRAINING

          The tasks in the task set are being stopped, and their corresponding targets are being deregistered from their target group.

        • taskDefinition — (String)

          The task definition that the task set is using.

        • computedDesiredCount — (Integer)

          The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.

        • pendingCount — (Integer)

          The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it's restarted after being in the STOPPED state.

        • runningCount — (Integer)

          The number of tasks in the task set that are in the RUNNING status during a deployment. A task in the RUNNING state is running and ready for use.

        • createdAt — (Date)

          The Unix timestamp for the time when the task set was created.

        • updatedAt — (Date)

          The Unix timestamp for the time when the task set was last updated.

        • launchType — (String)

          The launch type the tasks in the task set are using. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

          Possible values include:
          • "EC2"
          • "FARGATE"
          • "EXTERNAL"
        • capacityProviderStrategy — (Array<map>)

          • weight — (Integer)

            The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

            If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

            An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

          • base — (Integer)

            The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

        • platformVersion — (String)

          The Fargate platform version where the tasks in the task set are running. A platform version is only specified for tasks run on Fargate. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

        • platformFamily — (String)

          The operating system that your tasks in the set are running on. A platform family is specified only for tasks that use the Fargate launch type.

          All tasks in the set must have the same value.

        • networkConfiguration — (map)

          The network configuration for the task set.

          • awsvpcConfiguration — (map)

            The VPC subnets and security groups that are associated with a task.

            Note: All specified subnets and security groups must be from the same VPC.
            • subnetsrequired — (Array<String>)

              The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per awsvpcConfiguration.

              Note: All specified subnets must be from the same VPC.
            • securityGroups — (Array<String>)

              The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration.

              Note: All specified security groups must be from the same VPC.
            • assignPublicIp — (String)

              Whether the task's elastic network interface receives a public IP address. The default value is DISABLED.

              Possible values include:
              • "ENABLED"
              • "DISABLED"
        • loadBalancers — (Array<map>)

          Details on a load balancer that are used with a task set.

          • targetGroupArn — (String)

            The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

            A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

            For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

            For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.

            If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance. Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

          • loadBalancerName — (String)

            The name of the load balancer to associate with the Amazon ECS service or task set.

            If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

            The name of the container (as it appears in a container definition) to associate with the load balancer.

            You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

          • containerPort — (Integer)

            The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

        • serviceRegistries — (Array<map>)

          The details for the service discovery registries to assign to this task set. For more information, see Service discovery.

          • registryArn — (String)

            The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.

          • port — (Integer)

          • containerName — (String)

            The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

          • containerPort — (Integer)

            The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

        • scale — (map)

          A floating-point percentage of your desired number of tasks to place and keep running in the task set.

          • value — (Float)

          • unit — (String)

            The unit of measure for the scale value.

            Possible values include:
            • "PERCENT"
        • stabilityStatus — (String)

          The stability status. This indicates whether the task set has reached a steady state. If the following conditions are met, the task set are in STEADY_STATE:

          • The pendingCount is 0.

          • There are no tasks that are running on container instances in the DRAINING status.

          • All tasks are reporting a healthy status from the load balancers, service discovery, and container health checks.

          If any of those conditions aren't met, the stability status returns STABILIZING.

Calling the getTaskProtection operation

var params = {
  cluster: 'STRING_VALUE', /* required */
  tasks: [
    'STRING_VALUE',
    /* more items */
  ]
};
ecs.getTaskProtection(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
