Class: AWS.ECS

Inherits:
AWS.Service show all
Identifier:
ecs
API Version:
2014-11-13
Defined in:
(unknown)

Overview

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

Sending a Request Using ECS

var ecs = new AWS.ECS();
ecs.createCluster(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

Examples:

Constructing a ECS object

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

Options Hash (options):

  • params (map)

    An optional map of parameters to bind to every request sent by this service object. For more information on bound parameters, see "Working with Services" in the Getting Started Guide.

  • endpoint (String)

    The endpoint URI to send requests to. The default endpoint is built from the configured region. The endpoint should be a string like 'https://{service}.{region}.amazonaws.com'.

  • accessKeyId (String)

    your AWS access key ID.

  • secretAccessKey (String)

    your AWS secret access key.

  • sessionToken (AWS.Credentials)

    the optional AWS session token to sign requests with.

  • credentials (AWS.Credentials)

    the AWS credentials to sign requests with. You can either specify this object, or specify the accessKeyId and secretAccessKey options directly.

  • credentialProvider (AWS.CredentialProviderChain)

    the provider chain used to resolve credentials if no static credentials property is set.

  • region (String)

    the region to send service requests to. See AWS.ECS.region for more information.

  • maxRetries (Integer)

    the maximum amount of retries to attempt with a request. See AWS.ECS.maxRetries for more information.

  • maxRedirects (Integer)

    the maximum amount of redirects to follow with a request. See AWS.ECS.maxRedirects for more information.

  • sslEnabled (Boolean)

    whether to enable SSL for requests.

  • paramValidation (Boolean|map)

    whether input parameters should be validated against the operation description before sending the request. Defaults to true. Pass a map to enable any of the following specific validation features:

    • min [Boolean] — Validates that a value meets the min constraint. This is enabled by default when paramValidation is set to true.
    • max [Boolean] — Validates that a value meets the max constraint.
    • pattern [Boolean] — Validates that a string value matches a regular expression.
    • enum [Boolean] — Validates that a string value matches one of the allowable enum values.
  • computeChecksums (Boolean)

    whether to compute checksums for payload bodies when the service accepts it (currently supported in S3 only)

  • convertResponseTypes (Boolean)

    whether types are converted when parsing response data. Currently only supported for JSON based services. Turning this off may improve performance on large response payloads. Defaults to true.

  • correctClockSkew (Boolean)

    whether to apply a clock skew correction and retry requests that fail because of an skewed client clock. Defaults to false.

  • s3ForcePathStyle (Boolean)

    whether to force path style URLs for S3 objects.

  • s3BucketEndpoint (Boolean)

    whether the provided endpoint addresses an individual bucket (false if it addresses the root API endpoint). Note that setting this configuration option requires an endpoint to be provided explicitly to the service constructor.

  • s3DisableBodySigning (Boolean)

    whether S3 body signing should be disabled when using signature version v4. Body signing can only be disabled when using https. Defaults to true.

  • retryDelayOptions (map)

    A set of options to configure the retry delay on retryable errors. Currently supported options are:

    • base [Integer] — The base number of milliseconds to use in the exponential backoff for operation retries. Defaults to 100 ms for all services except DynamoDB, where it defaults to 50ms.
    • customBackoff [function] — A custom function that accepts a retry count and returns the amount of time to delay in milliseconds. The base option will be ignored if this option is supplied.

    A set of options to pass to the low-level HTTP request. Currently supported options are:

    • proxy [String] — the URL to proxy requests through
    • agent [http.Agent, https.Agent] — the Agent object to perform HTTP requests with. Used for connection pooling. Defaults to the global agent (http.globalAgent) for non-SSL connections. Note that for SSL connections, a special Agent object is used in order to enable peer certificate verification. This feature is only available in the Node.js environment.
    • connectTimeout [Integer] — Sets the socket to timeout after failing to establish a connection with the server after connectTimeout milliseconds. This timeout has no effect once a socket connection has been established.
    • timeout [Integer] — Sets the socket to timeout after timeout milliseconds of inactivity on the socket. Defaults to two minutes (120000).
    • xhrAsync [Boolean] — Whether the SDK will send asynchronous HTTP requests. Used in the browser environment only. Set to false to send requests synchronously. Defaults to true (async on).

    a map of service identifiers (the lowercase service class name) with the API version to use when instantiating a service. Specify 'latest' for each individual that can use the latest available version.

  • logger (#write, #log)

    an object that responds to .write() (like a stream) or .log() (like the console object) in order to log information about requests

  • systemClockOffset (Number)

    an offset value in milliseconds to apply to all signing times. Use this to compensate for clock skew when your system may be out of sync with the service time. Note that this configuration option can only be applied to the global AWS.config object and cannot be overridden in service-specific configuration. Defaults to 0 milliseconds.

Method Details

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 with the CreateCluster action.

Note: When you call the CreateCluster API operation, Amazon ECS attempts to create the service-linked role for your account so that required resources in other AWS services can be managed on your behalf. However, if the IAM user that makes the call does not have permissions to create the service-linked role, it is not created. For more information, see Using Service-Linked Roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

Examples:

To create a new cluster


/* This example creates a cluster in your default region. */

 var params = {
  clusterName: "my_cluster"
 };
 ecs.createCluster(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*
   data = {
    cluster: {
     activeServicesCount: 0, 
     clusterArn: "arn:aws:ecs:us-east-1:012345678910:cluster/my_cluster", 
     clusterName: "my_cluster", 
     pendingTasksCount: 0, 
     registeredContainerInstancesCount: 0, 
     runningTasksCount: 0, 
     status: "ACTIVE"
    }
   }
   */
 });

Calling the createCluster operation

var params = {
  clusterName: 'STRING_VALUE'
};
ecs.createCluster(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: {})
    • clusterName — (String)

      The name of your cluster. If you do not specify a name for your cluster, you create a cluster named default. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.

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:

      • cluster — (map)

        The full description of your new cluster.

        • clusterArn — (String)

          The Amazon Resource Name (ARN) that identifies the cluster. The ARN contains the arn:aws:ecs namespace, followed by the Region of the cluster, the AWS account ID of the cluster owner, the cluster namespace, and then the cluster name.

Returns:

  • (AWS.Request)

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

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

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

In addition to maintaining the desired count of tasks in your service, you can optionally run your service behind a load balancer. The load balancer distributes 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 optionally specify a deployment configuration for your service. During a deployment, the service scheduler uses the minimumHealthyPercent and maximumPercent parameters to determine the deployment strategy. The deployment is triggered by changing the task definition or the desired count of a service with an UpdateService operation.

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 scheduler can stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state. Tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and the container instance they are hosted on is reported as healthy by the load balancer. The default value for a replica service for minimumHealthyPercent is 50% in the console and 100% for the AWS CLI, the AWS SDKs, and the APIs. The default value for a daemon service for minimumHealthyPercent is 0% for the AWS CLI, the AWS SDKs, and the APIs and 50% for the console.

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 replica service has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler can 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 a replica service for maximumPercent is 200%. If you are using a daemon service type, the maximumPercent should remain at 100%, which is the default value.

When the service scheduler launches new tasks, it determines task placement in your cluster using the following logic:

  • Determine which of the container instances in your cluster can support your service's task definition (for example, they have the required CPU, memory, ports, and container instance attributes).

  • By default, the service scheduler attempts to balance tasks across Availability Zones in this manner (although you can choose a different placement strategy) with the placementStrategy parameter):

    • Sort the valid container instances, giving priority to instances that have the fewest number of running tasks for this service in their respective Availability Zone. For example, if zone A has one running service task and zones B and C each have zero, valid container instances in either zone B or C are considered optimal for placement.

    • Place the new service task on a valid container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the fewest number of running tasks for this service.

Parameters:

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

      The short name or full Amazon Resource Name (ARN) of the cluster on which to run your service. 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, hyphens, and underscores 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 is not specified, the latest ACTIVE revision is used.

    • loadBalancers — (Array<map>)

      A load balancer object representing the load balancer to use with your service. Currently, you are limited to one load balancer or target group per service. After you create a service, the load balancer name or target group ARN, container name, and container port specified in the service definition are immutable.

      For Classic Load Balancers, this object must contain the load balancer name, the container name (as it appears in a container definition), and the container port to access from the load balancer. When a task from this service is placed on a container instance, the container instance is registered with the load balancer specified here.

      For Application Load Balancers and Network Load Balancers, this object must contain the load balancer target group ARN, the container name (as it appears in a container definition), and the container port to access from the load balancer. 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 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 are not supported. Also, when you create any target groups for these services, you must choose ip as the target type, not instance, 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 associated with a service.

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

      • loadBalancerName — (String)

        The name of a load balancer.

      • containerName — (String)

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

      • containerPort — (Integer)

        The port on the container to associate with the load balancer. This port must correspond to a containerPort in the service's task definition. Your container instances 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 service. For more information, see Service Discovery.

      Note: Service discovery is supported for Fargate tasks if using platform version v1.1.0 or later. For more information, see AWS Fargate Platform Versions.
      • registryArn — (String)

        The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Amazon Route 53 Auto Naming. For more information, see Service.

      • port — (Integer)

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

      • containerName — (String)

        The container name value, already specified in the task definition, to be used for your service discovery service. 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, but not both.

      • containerPort — (Integer)

        The port value, already specified in the task definition, to be used for your service discovery service. 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, but not both.

      Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Up to 32 ASCII characters are allowed.

    • launchType — (String)

      The launch type on which to run your service.

      Possible values include:
      • "EC2"
      • "FARGATE"
    • platformVersion — (String)

      The platform version on which to run your service. If one is not specified, the latest version is used by default.

    • 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 does not 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 by default for your service unless you specify a role here. The service-linked role is required if your task definition uses the awsvpc network mode, in which case you should not 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.

        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. The value distinctInstance is not supported in task definitions.

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

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 is 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 is 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 is not supported for other network modes. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

    • healthCheckGracePeriodSeconds — (Integer)

      The period of time, in seconds, that the Amazon ECS service scheduler should ignore unhealthy Elastic Load Balancing target health checks after a task has first started. This is only valid if your service is configured to use a load balancer. 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 7,200 seconds during which the ECS service scheduler ignores health check status. This grace period can prevent the ECS 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.

      • 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. When using this strategy, there is no need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies.

        Note: Fargate tasks do not support the DAEMON scheduling strategy.
      Possible values include:
      • "REPLICA"
      • "DAEMON"

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, but not both.

          • containerPort — (Integer)

            The port value, already specified in the task definition, to be used for your service discovery service.

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 cannot 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 ListServices API operations. After the tasks have stopped, then the service status moves from DRAINING to INACTIVE. Services in the DRAINING or INACTIVE status can still be viewed with DescribeServices API operations. However, in the future, INACTIVE services may be cleaned up and purged from Amazon ECS record keeping, and DescribeServices API operations 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 will 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
};
ecs.deleteService(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 service to delete. If you do not specify a cluster, the default cluster is assumed.

    • service — (String)

      The name of the service to delete.

    • force — (Boolean)

      If true, allows you to delete a service even if it has not been scaled down to zero tasks. It is only necessary to use this if the service is using the REPLICA scheduling strategy.

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.

    • (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 the deleted service.

        • serviceArn — (String)

          The ARN that identifies the service. The ARN contains the arn:aws:ecs namespace, followed by the Region of the service, the AWS account ID of the service owner, the service namespace, and then the service name. For example, arn:aws:ecs:region:012345678910:service/my-service .

        • serviceName — (String)

          The name of your service. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores 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.

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

          • loadBalancerName — (String)

            The name of a load balancer.

          • containerName — (String)

        • serviceRegistries — (Array<map>)

          • registryArn — (String)

            The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Amazon Route 53 Auto Naming. For more information, see Service.

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

          • containerName — (String)

            The container name value, already specified in the task definition, to be used for your service discovery service. 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, but not both.

          • containerPort — (Integer)

            The port value, already specified in the task definition, to be used for your service discovery service. 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.

          • DAEMON-The daemon scheduling strategy deploys exactly one task on each container instance in your cluster. When using this strategy, do not specify a desired number of tasks or any task placement strategies.

            Note: Fargate tasks do not support the DAEMON scheduling strategy.
          Possible values include:
          • "REPLICA"
          • "DAEMON"

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, you should 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 does not 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 are not 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. The ARN contains the arn:aws:ecs namespace, followed by the Region of the container instance, the AWS account ID of the container instance owner, the container-instance namespace, and then the container instance ID. For example, arn:aws:ecs:region:aws_account_id:container-instance/container_instance_ID .

    • force — (Boolean)

      Forces the deregistration of the container instance. 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 are 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:

      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:

      • containerInstance — (map)

        The container instance that was deregistered.

        • containerInstanceArn — (String)

          The Amazon Resource Name (ARN) of the container instance. The ARN contains the arn:aws:ecs namespace, followed by the Region of the container instance, the AWS account ID of the container instance owner, the container-instance namespace, and then the container instance ID. For example, arn:aws:ecs:region:aws_account_id:container-instance/container_instance_ID .

          The EC2 instance ID of the container instance.

        • version — (Integer)

          The version counter for the container instance. Every time a container instance experiences a change that triggers a CloudWatch event, the version counter is incremented. If you are replicating your Amazon ECS container instance state with CloudWatch Events, you can compare the version of a container instance reported by the Amazon ECS APIs with the version reported in CloudWatch Events for the container instance (inside the detail object) to verify that the version in your event stream is current.

        • versionInfo — (map)

          The version information for the Amazon ECS container agent and Docker daemon running on the container instance.

          • agentVersion — (String)

        • registeredResources — (Array<map>)

          For CPU and memory resource types, this parameter describes the amount of each resource that was available on the container instance when the container agent registered it with Amazon ECS; this value represents the total amount of CPU and memory that can be allocated on this container instance to tasks. For port resource types, this parameter describes the ports that were reserved by the Amazon ECS container agent when it registered the container instance with Amazon ECS.

          • name — (String)

            The name of the resource, such as CPU, MEMORY, PORTS, PORTS_UDP, or a user-defined resource.

          • type — (String)

            When the stringSetValue type is set, the value of the resource must be a string type.

        • status — (String)

          The status of the container instance. The valid values are ACTIVE, INACTIVE, or DRAINING. ACTIVE indicates that the container instance can accept tasks. DRAINING indicates that new tasks are not 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.

        • agentConnected — (Boolean)

          This parameter returns true if the agent is connected to Amazon ECS. Registered instances with an agent that may be unhealthy or stopped return false. Only instances connected to an agent can accept placement requests.

        • runningTasksCount — (Integer)

          The number of tasks on the container instance that are in the RUNNING status.

        • pendingTasksCount — (Integer)

          The number of tasks on the container instance that are in the PENDING status.

        • agentUpdateStatus — (String)

          Possible values include:
          • "PENDING"
          • "STAGING"
          • "STAGED"
          • "UPDATING"

          • value — (String)

            The value of the attribute. Up to 128 letters (uppercase and lowercase), numbers, hyphens, underscores, periods, at signs (@), forward slashes, colons, and spaces are allowed.

          • targetType — (String)

            The type of the target with which to attach the attribute. This parameter is required if you use the short form ID for a resource instead of the full ARN.

            Possible values include:
            • "container-instance"
          • targetId — (String)

            The ID of the target. You can specify the short form ID for a resource or the full Amazon Resource Name (ARN).

            • value — (String)

              The value of the key value pair. For environment variables, this is the value of the environment variable.

Returns:

  • (AWS.Request)

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

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.

You cannot use an INACTIVE task definition to run new tasks or create new services, and you cannot update an existing service to reference an INACTIVE task definition (although 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, so you should not rely on INACTIVE task definitions persisting beyond the lifecycle of any associated tasks and services.

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 are 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, hyphens, and underscores are allowed. This parameter maps to name in the Create a container section of the Docker Remote API 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. Images in the Docker Hub registry are available by default. 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 Create a container section of the Docker Remote API 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 are not 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) or name of the secret containing the private repository credentials.

          • cpu — (Integer)

            The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and 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.

            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 is 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 would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.

            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 is 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 would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but 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. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2; however, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), 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 2 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.

            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 is described in the task definition.

          • memory — (Integer)

            The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

            If your containers are part of a task using the Fargate launch type, this field is optional and the only requirement is that the total amount of memory reserved for all containers within a task be lower than the task memory value.

            For containers that are part of a task using the EC2 launch type, you must specify a non-zero integer for one or both of memory or memoryReservation in container definitions. 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 on which the container is placed; otherwise, the value of memory is used.

            The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer 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 Create a container section of the Docker Remote API and the --memory-reservation option to docker run.

            You must specify a non-zero integer for one or both of memory or memoryReservation in container definitions. 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 on which 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 daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.

          • links — (Array<String>)

            The link parameter allows containers to communicate with each other without the need for port mappings. Only supported if the network mode of a task definition is set to bridge. The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. For more information about linking Docker containers, go to https://docs.docker.com/engine/userguide/networking/default_network/dockerlinks/. This parameter maps to Links in the Create a container section of the Docker Remote API 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, you should 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 is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself.

            This parameter maps to PortBindings in the Create a container section of the Docker Remote API 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 is bound to the user-specified or automatically assigned host port.

              If using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort.

              If using 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 using 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 using 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 is used. You should 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.

              Note: The default ephemeral port range from 49153 through 65535 is always used for Docker versions before 1.6.0.

              The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678 and 51679. Any host port that was previously specified in a running task is also reserved while the task is running (after a task stops, the host port is released). The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output, and a container instance may have up to 100 reserved ports at a time, including the default reserved ports (automatically assigned ports do not count toward the 100 reserved ports limit).

            • protocol — (String)

              The protocol used for the port mapping. Valid values are tcp and udp. The default is tcp.

              Possible values include:
              • "tcp"
              • "udp"
          • 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, then its failure does not 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 is composed of multiple containers, you should 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.

          • entryPoint — (Array<String>)

            Early versions of the Amazon ECS container agent do not 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 is passed to the container. This parameter maps to Entrypoint in the Create a container section of the Docker Remote API and the --entrypoint option to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint.

          • command — (Array<String>)

            The command that is passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd.

          • environment — (Array<map>)

            The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run.

            We do not recommend using 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.

          • mountPoints — (Array<map>)

            The mount points for data volumes in your container.

            This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run.

            Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers cannot mount directories on a different drive, and mount point cannot 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 the Create a container section of the Docker Remote API 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 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: If you are using tasks that use the Fargate launch type, capabilities is supported but the add parameter is not supported.
              • 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 Create a container section of the Docker Remote API and the --cap-add option to docker run.

                Note: If you are using tasks that use the Fargate launch type, the add parameter is not supported.

                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"

            This parameter maps to SecurityOpt in the Create a container section of the Docker Remote API 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. This parameter is not supported for Windows containers.
          • interactive — (Boolean)

            When this parameter is true, this allows you to deploy containerized applications that require stdin or a tty to be allocated. This parameter maps to OpenStdin in the Create a container section of the Docker Remote API and the --interactive option to docker run.

          • pseudoTerminal — (Boolean)

          • dockerLabels — (map<String>)

            A key/value map of labels to add to the container. This parameter maps to Labels in the Create a container section of the Docker Remote API 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 | grep "Server API version"

          • ulimits — (Array<map>)

            A list of ulimits to set in the container. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type. 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 | grep "Server API version"

            Note: This parameter is not supported for Windows containers.

              • "rttime"
              • "sigpending"
              • "stack"
            • softLimitrequired — (Integer)

            • hardLimitrequired — (Integer)

              The hard limit for the ulimit type.

          • logConfiguration — (map)

            The log configuration specification for the container.

            If using the Fargate launch type, the only supported value is awslogs.

            This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses; however the container may 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). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

            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 | grep "Server API version"

            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. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default. If using the Fargate launch type, the only supported value is awslogs. For more information about using the awslogs driver, see Using the awslogs Log Driver in the Amazon Elastic Container Service Developer Guide.

              Note: If you have a custom driver that is not listed above that you would like to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that is 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, Amazon Web Services does not currently support running modified copies of this software.

              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 | grep "Server API version"

              Possible values include:
              • "json-file"
              • "syslog"
              • "journald"
              • "gelf"
              • "fluentd"
              • "awslogs"
              • "splunk"
            • 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 | grep "Server API version"

          • healthCheck — (map)

            The health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API 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 execute the command arguments directly, or CMD-SHELL to run the command with the container's default shell. For example:

              [ "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 the Create a container section of the Docker Remote API.

            • 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 within which to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You may specify between 0 and 300 seconds. The startPeriod is disabled by default.

              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 the Create a container section of the Docker Remote API and the --sysctl option to docker run.

            Note: It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. When you do, the container that is started last will determine which systemControls parameters take effect.
            • namespace — (String)

              The namespaced kernel parameter to set a value for.

            • value — (String)

              The value for the namespaced kernel parameter specifed in namespace.

        • family — (String)

          The family of your task definition, used as the definition name.

        • taskRoleArn — (String)

          The ARN of the IAM role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role.

          IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code in order to take advantage of the feature. For more information, see Windows IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.

        • executionRoleArn — (String)

          The Amazon Resource Name (ARN) of the task execution role that the Amazon ECS container agent and the Docker daemon can assume.

        • networkMode — (String)

          The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. The default Docker network mode is bridge. If using the Fargate launch type, the awsvpc network mode is required. If using the EC2 launch type, any network mode can be used. If the network mode is set to none, you can't specify port mappings in your container definitions, and the task's 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.

          If the network mode is awsvpc, the task is allocated an Elastic Network Interface, and you must specify a NetworkConfiguration 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.

          Note: Currently, only the Amazon ECS-optimized AMI, other Amazon Linux variants with the ecs-init package, or AWS Fargate infrastructure support the awsvpc network mode.

          If the network mode is host, you can't run multiple instantiations of the same task on a single container instance when port mappings are used.

          Docker for Windows uses different network modes than Docker for Linux. When you register a task definition with Windows containers, you must not specify a network mode. If you use the console to register a task definition with Windows containers, you must choose the <default> network mode object.

          For more information, see Network settings in the Docker run reference.

          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 you register a new revision of a task definition in the same family, the revision value always increases by one (even if you have deregistered previous revisions in this family).

        • volumes — (Array<map>)

          The list of volumes in a task.

          If you are using the Fargate launch type, the host and sourcePath parameters are not supported.

          For more information about volume definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.

          • name — (String)

            The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints.

          • host — (map)

            This parameter is specified when using bind mount host volumes. Bind mount host volumes are supported when using either the EC2 or Fargate launch types. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it is stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume, but the data is not guaranteed to persist after the containers associated with it stop running.

            Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers cannot mount directories on a different drive, and mount point cannot 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 is 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 does not 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 are using the Fargate launch type, the sourcePath parameter is not supported.

          • dockerVolumeConfiguration — (map)

            This parameter is specified when using Docker volumes. Docker volumes are only supported when using the EC2 launch type. Windows containers only support the use of the local driver. To use bind mounts, specify a host instead.

            • scope — (String)

              The scope for the Docker volume which determines it's 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 does not 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. For more information, see Docker plugin discovery. This parameter maps to Driver in the Create a volume section of the Docker Remote API 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 Create a volume section of the Docker Remote API 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 Create a volume section of the Docker Remote API and the xxlabel option to docker volume create .

        • status — (String)

          The status of the task definition.

          Possible values include:
          • "ACTIVE"
          • "INACTIVE"
        • requiresAttributes — (Array<map>)

          The container instance attributes required by your task. This field is not valid if using the Fargate launch type for your task.

          • namerequired — (String)

            The name of the attribute. Up to 128 letters (uppercase and lowercase), numbers, hyphens, underscores, and periods are allowed.

          • value — (String)

            The value of the attribute. Up to 128 letters (uppercase and lowercase), numbers, hyphens, underscores, periods, at signs (@), forward slashes, colons, and spaces are allowed.

          • targetType — (String)

            The type of the target with which to attach the attribute. This parameter is required if you use the short form ID for a resource instead of the full ARN.

            Possible values include:
            • "container-instance"
          • targetId — (String)

            The ID of the target. You can specify the short form ID for a resource or the full Amazon Resource Name (ARN).

        • placementConstraints — (Array<map>)

          An array of placement constraint objects to use for tasks. This field is not valid if using the Fargate launch type for your task.

          • type — (String)

            The type of constraint. The DistinctInstance constraint ensures that each task in a particular group is running on a different container instance. The MemberOf constraint restricts selection to be from a group of valid candidates.

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

            A cluster query language expression to apply to the constraint. For more information, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide.

        • compatibilities — (Array<String>)

          The launch type to use with your task. For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide.

        • requiresCompatibilities — (Array<String>)

          The launch type the task is using.

        • cpu — (String)

          The number of cpu units used by the task. If using the EC2 launch type, this field is optional and any value can be used. If using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of valid values for the memory parameter:

      • services — (Array<map>)

        The list of services described.

        • serviceArn — (String)

          The ARN that identifies the service. The ARN contains the arn:aws:ecs namespace, followed by the Region of the service, the AWS account ID of the service owner, the service namespace, and then the service name. For example, arn:aws:ecs:region:012345678910:service/my-service .

        • serviceName — (String)

          The name of your service. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores 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.

        • 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, containing the load balancer name, the container name (as it appears in a container definition), and the container port to access from the load balancer.

          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 are not supported. Also, when you create any target groups for these services, you must choose ip as the target type, not instance, 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 associated with a service.

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

          • loadBalancerName — (String)

            The name of a load balancer.

          • containerName — (String)

            The port on the container to associate with the load balancer. This port must correspond to a containerPort in the service's task definition. Your container instances must allow ingress traffic on the hostPort of the port mapping.

        • serviceRegistries — (Array<map>)

          • registryArn — (String)

            The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Amazon Route 53 Auto Naming. For more information, see Service.

          • port — (Integer)

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

          • containerName — (String)

            The container name value, already specified in the task definition, to be used for your service discovery service. 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, but not both.

          • containerPort — (Integer)

            The port value, already specified in the task definition, to be used for your service discovery service. 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, but not both.

          The Unix time stamp for 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. The value distinctInstance is not supported in task definitions.

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

            A cluster query language expression to apply to the constraint. You cannot 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 is 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 is 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 associated with a task.

            • securityGroups — (Array<String>)

              The security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is a limit of 5 security groups able to 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 container instance in your cluster. When using this strategy, do not specify a desired number of tasks or any task placement strategies.

            Note: Fargate tasks do not support the DAEMON scheduling strategy.
          Possible values include:
          • "REPLICA"
          • "DAEMON"
      • 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.

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 */
};
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.

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 are 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, hyphens, and underscores are allowed. This parameter maps to name in the Create a container section of the Docker Remote API 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. Images in the Docker Hub registry are available by default. 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 Create a container section of the Docker Remote API 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 are not 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) or name of the secret containing the private repository credentials.

          • cpu — (Integer)

            The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and 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.

            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 is 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 would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.

            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 is 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 would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but 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. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2; however, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), 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 2 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.

            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 is described in the task definition.

          • memory — (Integer)

            The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

            If your containers are part of a task using the Fargate launch type, this field is optional and the only requirement is that the total amount of memory reserved for all containers within a task be lower than the task memory value.

            For containers that are part of a task using the EC2 launch type, you must specify a non-zero integer for one or both of memory or memoryReservation in container definitions. 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 on which the container is placed; otherwise, the value of memory is used.

            The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer 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 Create a container section of the Docker Remote API and the --memory-reservation option to docker run.

            You must specify a non-zero integer for one or both of memory or memoryReservation in container definitions. 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 on which 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 daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.

          • links — (Array<String>)

            The link parameter allows containers to communicate with each other without the need for port mappings. Only supported if the network mode of a task definition is set to bridge. The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. For more information about linking Docker containers, go to https://docs.docker.com/engine/userguide/networking/default_network/dockerlinks/. This parameter maps to Links in the Create a container section of the Docker Remote API 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, you should 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 is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself.

            This parameter maps to PortBindings in the Create a container section of the Docker Remote API 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 is bound to the user-specified or automatically assigned host port.

              If using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort.

              If using 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 using 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 using 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 is used. You should 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.

              Note: The default ephemeral port range from 49153 through 65535 is always used for Docker versions before 1.6.0.

              The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678 and 51679. Any host port that was previously specified in a running task is also reserved while the task is running (after a task stops, the host port is released). The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output, and a container instance may have up to 100 reserved ports at a time, including the default reserved ports (automatically assigned ports do not count toward the 100 reserved ports limit).

            • protocol — (String)

              The protocol used for the port mapping. Valid values are tcp and udp. The default is tcp.

              Possible values include:
              • "tcp"
              • "udp"
          • 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, then its failure does not 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 is composed of multiple containers, you should 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.

          • entryPoint — (Array<String>)

            Early versions of the Amazon ECS container agent do not 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.

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 | grep "Server API version"

          • ulimits — (Array<map>)

            A list of ulimits to set in the container. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type. 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 | grep "Server API version"

          • logConfiguration — (map)

            The log configuration specification for the container.

            If using the Fargate launch type, the only supported value is awslogs.

            This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses; however the container may 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). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

            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 | grep "Server API version"

            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. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default. If using the Fargate launch type, the only supported value is awslogs. For more information about using the awslogs driver, see Using the awslogs Log Driver in the Amazon Elastic Container Service Developer Guide.

              Note: If you have a custom driver that is not listed above that you would like to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that is 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, Amazon Web Services does not currently support running modified copies of this software.

              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 | grep "Server API version"

              Possible values include:
              • "json-file"
              • "syslog"
              • "journald"
              • "gelf"
              • "fluentd"
              • "awslogs"
              • "splunk"
            • 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 | grep "Server API version"

          • healthCheck — (map)

            The health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API 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 execute the command arguments directly, or CMD-SHELL to run the command with the container's default shell. For example:

              [ "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 the Create a container section of the Docker Remote API.

            • 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 within which to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You may specify between 0 and 300 seconds. The startPeriod is disabled by default.

              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 the Create a container section of the Docker Remote API and the --sysctl option to docker run.

            Note: It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. When you do, the container that is started last will determine which systemControls parameters take effect.
            • namespace — (String)

              The namespaced kernel parameter to set a value for.

            • value — (String)

              The value for the namespaced kernel parameter specifed in namespace.

        • family — (String)

          The family of your task definition, used as the definition name.

        • taskRoleArn — (String)

          The ARN of the IAM role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role.

          IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code in order to take advantage of the feature. For more information, see Windows IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.

        • executionRoleArn — (String)

          The Amazon Resource Name (ARN) of the task execution role that the Amazon ECS container agent and the Docker daemon can assume.

        • networkMode — (String)

          The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. The default Docker network mode is bridge. If using the Fargate launch type, the awsvpc network mode is required. If using the EC2 launch type, any network mode can be used. If the network mode is set to none, you can't specify port mappings in your container definitions, and the task's 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.

          If the network mode is awsvpc, the task is allocated an Elastic Network Interface, and you must specify a NetworkConfiguration 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.

          Note: Currently, only the Amazon ECS-optimized AMI, other Amazon Linux variants with the ecs-init package, or AWS Fargate infrastructure support the awsvpc network mode.

          If the network mode is host, you can't run multiple instantiations of the same task on a single container instance when port mappings are used.

          Docker for Windows uses different network modes than Docker for Linux. When you register a task definition with Windows containers, you must not specify a network mode. If you use the console to register a task definition with Windows containers, you must choose the <default> network mode object.

          For more information, see Network settings in the Docker run reference.

          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 you register a new revision of a task definition in the same family, the revision value always increases by one (even if you have deregistered previous revisions in this family).

        • volumes — (Array<map>)

          The list of volumes in a task.

          If you are using the Fargate launch type, the host and sourcePath parameters are not supported.

          For more information about volume definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.

          • name — (String)

            The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints.

          • host — (map)

            This parameter is specified when using bind mount host volumes. Bind mount host volumes are supported when using either the EC2 or Fargate launch types. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it is stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume, but the data is not guaranteed to persist after the containers associated with it stop running.

            Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers cannot mount directories on a different drive, and mount point cannot 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 is 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 does not 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 are using the Fargate launch type, the sourcePath parameter is not supported.

          • dockerVolumeConfiguration — (map)

            This parameter is specified when using Docker volumes. Docker volumes are only supported when using the EC2 launch type. Windows containers only support the use of the local driver. To use bind mounts, specify a host instead.

            • scope — (String)

              The scope for the Docker volume which determines it's 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 does not 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. For more information, see Docker plugin discovery. This parameter maps to Driver in the Create a volume section of the Docker Remote API 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 Create a volume section of the Docker Remote API 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 Create a volume section of the Docker Remote API and the xxlabel option to docker volume create .

        • status — (String)

          The status of the task definition.

          Possible values include:
          • "ACTIVE"
          • "INACTIVE"
        • requiresAttributes — (Array<map>)

          The container instance attributes required by your task. This field is not valid if using the Fargate launch type for your task.

          • namerequired — (String)

            The name of the attribute. Up to 128 letters (uppercase and lowercase), numbers, hyphens, underscores, and periods are allowed.

          • value — (String)

            The value of the attribute. Up to 128 letters (uppercase and lowercase), numbers, hyphens, underscores, periods, at signs (@), forward slashes, colons, and spaces are allowed.

          • targetType — (String)

            The type of the target with which to attach the attribute. This parameter is required if you use the short form ID for a resource instead of the full ARN.

            Possible values include:
            • "container-instance"
          • targetId — (String)

            The ID of the target. You can specify the short form ID for a resource or the full Amazon Resource Name (ARN).

        • placementConstraints — (Array<map>)

          An array of placement constraint objects to use for tasks. This field is not valid if using the Fargate launch type for your task.

          • type — (String)

            The type of constraint. The DistinctInstance constraint ensures that each task in a particular group is running on a different container instance. The MemberOf constraint restricts selection to be from a group of valid candidates.

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

        • cpu — (String)

          The number of cpu units used by the task. If using the EC2 launch type, this field is optional and any value can be used. If using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of valid values for the memory parameter:

          • 256 (.25 vCPU) - Available memory values: 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB)

Calling the listTaskDefinitions operation

var params = {
  familyPrefix: 'STRING_VALUE',
  maxResults: 0,
  nextToken: 'STRING_VALUE',
  sort: ASC | DESC,
  status: ACTIVE | INACTIVE
};
ecs.listTaskDefinitions(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: {})
    • familyPrefix — (String)

      The full family name with which to filter the ListTaskDefinitions results. Specifying a familyPrefix limits the listed task definitions to task definition revisions that belong to that family.

    • status — (String)

      The task definition status with which to filter the ListTaskDefinitions results. By default, only ACTIVE task definitions are listed. By setting this parameter to INACTIVE, you can view task definitions that are INACTIVE as long as an active task or service still references them. If you paginate the resulting output, be sure to keep the status value constant in each subsequent request.

      Possible values include:
      • "ACTIVE"
      • "INACTIVE"
    • sort — (String)

      The order in which to sort the results. Valid values are ASC and DESC. By default (ASC), task definitions are listed lexicographically by family name and in ascending numerical order by revision so that the newest task definitions in a family are listed last. Setting this parameter to DESC reverses the sort order on family name and revision so that the newest task definitions in a family are listed first.

      Possible values include:
      • "ASC"
      • "DESC"
    • nextToken — (String)

      The nextToken value returned from a previous paginated ListTaskDefinitions 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.
    • maxResults — (Integer)

      The maximum number of task definition results returned by ListTaskDefinitions in paginated output. When this parameter is used, ListTaskDefinitions 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 ListTaskDefinitions request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListTaskDefinitions returns up to 100 results and a nextToken value if applicable.

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:

      • taskDefinitionArns — (Array<String>)

        The list of task definition Amazon Resource Name (ARN) entries for the ListTaskDefinitions request.

      • nextToken — (String)

        The nextToken value to include in a future ListTaskDefinitions request. When the results of a ListTaskDefinitions request exceed maxResults, this value can be used to retrieve the next page of results. This value is null when there are no more results to return.

Returns:

  • (AWS.Request)

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

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

Returns a list of tasks for a specified cluster. You can filter the results by family name, by a particular container instance, or by the desired status of the task with the family, containerInstance, and desiredStatus parameters.

Recently stopped tasks might appear in the returned results. Currently, stopped tasks appear in the returned results for at least one hour.

Examples:

To list the tasks in a cluster


/* This example lists all of the tasks in a cluster. */

 var params = {
  cluster: "default"
 };
 ecs.listTasks(params, function(err, data) {

 var params = {
  cluster: "default", 
  containerInstance: "f6bbb147-5370-4ace-8c73-c7181ded911f"
 };
 ecs.listTasks(params, function(err, data) {

Calling the listTasks operation

var params = {
  cluster: 'STRING_VALUE',
  containerInstance: 'STRING_VALUE',
  desiredStatus: RUNNING | PENDING | STOPPED,
  family: 'STRING_VALUE',
  launchType: EC2 | FARGATE,
  maxResults: 0,
  nextToken: 'STRING_VALUE',
  serviceName: 'STRING_VALUE',
  startedBy: 'STRING_VALUE'
};
ecs.listTasks(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 tasks to list. 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 with which to filter the ListTasks results. Specifying a containerInstance limits the results to tasks that belong to that container instance.

    • family — (String)

      The name of the family with which to filter the ListTasks results. Specifying a family limits the results to tasks that belong to that family.

    • nextToken — (String)

      The nextToken value returned from a previous paginated ListTasks 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.
    • maxResults — (Integer)

      The maximum number of task results returned by ListTasks in paginated output. When this parameter is used, ListTasks 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 ListTasks request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListTasks returns up to 100 results and a nextToken value if applicable.

    • startedBy — (String)

      The startedBy value with which to filter the task results. Specifying a startedBy value limits the results to tasks that were started with that value.

    • serviceName — (String)

      The name of the service with which to filter the ListTasks results. Specifying a serviceName limits the results to tasks that belong to that service.

    • desiredStatus — (String)

      The task desired status with which to filter the ListTasks results. Specifying a desiredStatus of STOPPED limits the results to tasks that Amazon ECS has set the desired status to STOPPED, which can be useful for debugging tasks that are not starting properly or have died or finished. The default status filter is RUNNING, which shows tasks that Amazon ECS has set the desired status to RUNNING.

      Note: Although you can filter results based on a desired status of PENDING, this does not return any results because Amazon ECS never sets the desired status of a task to that value (only a task's lastStatus may have a value of PENDING).
      Possible values include:
      • "RUNNING"
      • "PENDING"
      • "STOPPED"
    • launchType — (String)

      The launch type for services to list.

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

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.

        The list of task ARN entries for the ListTasks request.

      • nextToken — (String)

        The nextToken value to include in a future ListTasks request. When the results of a ListTasks request exceed maxResults, this value can be used to retrieve the next page of results. This value is null when there are no more results to return.

Returns:

  • (AWS.Request)

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

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

Registers a new task definition from the supplied family and containerDefinitions. Optionally, you can add data volumes to your containers with the volumes parameter. For more information about task definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.

You can specify an IAM role for your task with the taskRoleArn parameter. When you specify an IAM role for a task, its containers can then use the latest versions of the AWS CLI or SDKs to make API requests to the AWS services that are specified in the IAM policy associated with the role. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.

You can specify a Docker networking mode for the containers in your task definition with the networkMode parameter. The available network modes correspond to those described in Network settings in the Docker run reference. If you specify the awsvpc network mode, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration 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.

});

Parameters:

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

      You must specify a family for a task definition, which allows you to track multiple versions of the same task definition. The family is used as a name for your task definition. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.

    • taskRoleArn — (String)

      The short name or full Amazon Resource Name (ARN) of the IAM role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.

    • executionRoleArn — (String)

      The Amazon Resource Name (ARN) of the task execution role that the Amazon ECS container agent and the Docker daemon can assume.

    • networkMode — (String)

      The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. The default Docker network mode is bridge. If using the Fargate launch type, the awsvpc network mode is required. If using the EC2 launch type, any network mode can be used. If the network mode is set to none, you can't specify port mappings in your container definitions, and the task's 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.

      If the network mode is awsvpc, the task is allocated an Elastic Network Interface, and you must specify a NetworkConfiguration 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 can't run multiple instantiations of the same task on a single container instance when port mappings are used.

      Docker for Windows uses different network modes than Docker for Linux. When you register a task definition with Windows containers, you must not specify a network mode.

      For more information, see Network settings in the Docker run reference.

      Possible values include:
      • "bridge"
      • "host"
      • "awsvpc"
      • "none"
    • containerDefinitions — (Array<map>)

      A list of container definitions in JSON format that describe the different containers that make up your task.

      • name — (String)

        The name of a container. If you are 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, hyphens, and underscores are allowed. This parameter maps to name in the Create a container section of the Docker Remote API 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. Images in the Docker Hub registry are available by default. 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 Create a container section of the Docker Remote API 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 are not 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) or name of the secret containing the private repository credentials.

      • cpu — (Integer)

        The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and 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.

        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 is 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 would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.

        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 is 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 would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but 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. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2; however, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), 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 2 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.

        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 is described in the task definition.

      • memory — (Integer)

        The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

        If your containers are part of a task using the Fargate launch type, this field is optional and the only requirement is that the total amount of memory reserved for all containers within a task be lower than the task memory value.

        For containers that are part of a task using the EC2 launch type, you must specify a non-zero integer for one or both of memory or memoryReservation in container definitions. 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 on which the container is placed; otherwise, the value of memory is used.

        The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer 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 Create a container section of the Docker Remote API and the --memory-reservation option to docker run.

        You must specify a non-zero integer for one or both of memory or memoryReservation in container definitions. 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 on which 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 daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.

      • links — (Array<String>)

        The link parameter allows containers to communicate with each other without the need for port mappings. Only supported if the network mode of a task definition is set to bridge. The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. For more information about linking Docker containers, go to https://docs.docker.com/engine/userguide/networking/default_network/dockerlinks/. This parameter maps to Links in the Create a container section of the Docker Remote API 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, you should 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 is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself.

        This parameter maps to PortBindings in the Create a container section of the Docker Remote API 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 is bound to the user-specified or automatically assigned host port.

          If using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort.

          If using 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 using 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 using 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 is used. You should 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.

          Note: The default ephemeral port range from 49153 through 65535 is always used for Docker versions before 1.6.0.

          The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678 and 51679. Any host port that was previously specified in a running task is also reserved while the task is running (after a task stops, the host port is released). The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output, and a container instance may have up to 100 reserved ports at a time, including the default reserved ports (automatically assigned ports do not count toward the 100 reserved ports limit).

        • protocol — (String)

          The protocol used for the port mapping. Valid values are tcp and udp. The default is tcp.

          Possible values include:
          • "tcp"
          • "udp"
      • 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, then its failure does not 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 is composed of multiple containers, you should 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.

        This parameter maps to SecurityOpt in the Create a container section of the Docker Remote API 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. This parameter is not supported for Windows containers.
      • interactive — (Boolean)

        When this parameter is true, this allows you to deploy containerized applications that require stdin or a tty to be allocated. This parameter maps to OpenStdin in the Create a container section of the Docker Remote API and the --interactive option to docker run.

      • pseudoTerminal — (Boolean)

        When this parameter is true, a TTY is allocated. This parameter maps to Tty in the Create a container section of the Docker Remote API and the --tty option to docker run.

      • logConfiguration — (map)

        The log configuration specification for the container.

        If using the Fargate launch type, the only supported value is awslogs.

        This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses; however the container may 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). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

        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 | grep "Server API version"

        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. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default. If using the Fargate launch type, the only supported value is awslogs. For more information about using the awslogs driver, see Using the awslogs Log Driver in the Amazon Elastic Container Service Developer Guide.

          Note: If you have a custom driver that is not listed above that you would like to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that is 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, Amazon Web Services does not currently support running modified copies of this software.

          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 | grep "Server API version"

          Possible values include:
          • "json-file"
          • "syslog"
          • "journald"
          • "gelf"

          • "splunk"
        • 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 | grep "Server API version"

      • healthCheck — (map)

        The health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API 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 execute the command arguments directly, or CMD-SHELL to run the command with the container's default shell. For example:

          [ "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 the Create a container section of the Docker Remote API.

        • 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 within which to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You may specify between 0 and 300 seconds. The startPeriod is disabled by default.

          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 the Create a container section of the Docker Remote API and the --sysctl option to docker run.

        Note: It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. When you do, the container that is started last will determine which systemControls parameters take effect.
        • namespace — (String)

          The namespaced kernel parameter to set a value for.

        • value — (String)

          The value for the namespaced kernel parameter specifed in namespace.

    • volumes — (Array<map>)

      A list of volume definitions in JSON format that containers in your task may use.

      • name — (String)

        The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints.

      • host — (map)

        This parameter is specified when using bind mount host volumes. Bind mount host volumes are supported when using either the EC2 or Fargate launch types. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it is stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume, but the data is not guaranteed to persist after the containers associated with it stop running.

        Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers cannot mount directories on a different drive, and mount point cannot 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 is 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 does not 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 are using the Fargate launch type, the sourcePath parameter is not supported.

      • dockerVolumeConfiguration — (map)

        This parameter is specified when using Docker volumes. Docker volumes are only supported when using the EC2 launch type. Windows containers only support the use of the local driver. To use bind mounts, specify a host instead.

        • scope — (String)

          The scope for the Docker volume which determines it's 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 does not 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. For more information, see Docker plugin discovery. This parameter maps to Driver in the Create a volume section of the Docker Remote API 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 Create a volume section of the Docker Remote API 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 Create a volume section of the Docker Remote API and the xxlabel option to docker volume create .

    • placementConstraints — (Array<map>)

      An array of placement constraint objects to use for the task. You can specify a maximum of 10 constraints per task (this limit includes constraints in the task definition and those specified at run time).

      • type — (String)

        The type of constraint. The DistinctInstance constraint ensures that each task in a particular group is running on a different container instance. The MemberOf constraint restricts selection to be from a group of valid candidates.

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

        A cluster query language expression to apply to the constraint. For more information, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide.

    • requiresCompatibilities — (Array<String>)

      The launch type required by the task. If no value is specified, it defaults to EC2.

    • cpu — (String)

      The number of CPU units used by the task. It can be expressed as an integer using CPU units, for example 1024, or as a string using vCPUs, for example 1 vCPU or 1 vcpu, in a task definition. String values are converted to an integer indicating the CPU units when the task definition is registered.

      Note: Task-level CPU and memory parameters are ignored for Windows containers. We recommend specifying container-level resources for Windows containers.

      If using the EC2 launch type, this field is optional. Supported values are between 128 CPU units (0.125 vCPUs) and 10240 CPU units (10 vCPUs).

      If using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of supported values for the memory parameter:

    • memory — (String)

      The amount of memory (in MiB) used by the task. It can be expressed as an integer using MiB, for example 1024, or as a string using GB, for example 1GB or 1 GB, in a task definition. String values are converted to an integer indicating the MiB when the task definition is registered.

      Note: Task-level CPU and memory parameters are ignored for Windows containers. We recommend specifying container-level resources for Windows containers.

      If using the EC2 launch type, this field is optional.

      If using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of supported 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)

      • 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) - Available cpu values: 1024 (1 vCPU)

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 registered task definition.

        • 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 are 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, hyphens, and underscores are allowed. This parameter maps to name in the Create a container section of the Docker Remote API 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. Images in the Docker Hub registry are available by default. 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 Create a container section of the Docker Remote API 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 are not 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) or name of the secret containing the private repository credentials.

          • cpu — (Integer)

            The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and 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.

            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 is 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 would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.

            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 is 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 would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but 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. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2; however, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), 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 2 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.

            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 is described in the task definition.

          • memory — (Integer)

            The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

            If your containers are part of a task using the Fargate launch type, this field is optional and the only requirement is that the total amount of memory reserved for all containers within a task be lower than the task memory value.

            For containers that are part of a task using the EC2 launch type, you must specify a non-zero integer for one or both of memory or memoryReservation in container definitions. 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 on which the container is placed; otherwise, the value of memory is used.

            The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer 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 Create a container section of the Docker Remote API and the --memory-reservation option to docker run.

            You must specify a non-zero integer for one or both of memory or memoryReservation in container definitions. 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 on which 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 daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.

          • links — (Array<String>)

            The link parameter allows containers to communicate with each other without the need for port mappings. Only supported if the network mode of a task definition is set to bridge. The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. For more information about linking Docker containers, go to https://docs.docker.com/engine/userguide/networking/default_network/dockerlinks/. This parameter maps to Links in the Create a container section of the Docker Remote API 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, you should 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 is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself.

            This parameter maps to PortBindings in the Create a container section of the Docker Remote API 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 is bound to the user-specified or automatically assigned host port.

              If using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort.

              If using 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 using 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 using 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 is used. You should 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.

              Note: The default ephemeral port range from 49153 through 65535 is always used for Docker versions before 1.6.0.

              The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678 and 51679. Any host port that was previously specified in a running task is also reserved while the task is running (after a task stops, the host port is released). The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output, and a container instance may have up to 100 reserved ports at a time, including the default reserved ports (automatically assigned ports do not count toward the 100 reserved ports limit).

            • protocol — (String)

              The protocol used for the port mapping. Valid values are tcp and udp. The default is tcp.

              Possible values include:
              • "tcp"
              • "udp"
          • 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, then its failure does not 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 is composed of multiple containers, you should 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.

          • entryPoint — (Array<String>)

            Early versions of the Amazon ECS container agent do not 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 is passed to the container. This parameter maps to Entrypoint in the Create a container section of the Docker Remote API and the --entrypoint option to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint.

          • command — (Array<String>)

            The command that is passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd.

          • environment — (Array<map>)

            The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run.

            We do not recommend using 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)

          • mountPoints — (Array<map>)

            The mount points for data volumes in your container.

            This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run.

            Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers cannot mount directories on a different drive, and mount point cannot 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 the Create a container section of the Docker Remote API 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)

            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: If you are using tasks that use the Fargate launch type, capabilities is supported but the add parameter is not supported.
              • 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 Create a container section of the Docker Remote API and the --cap-add option to docker run.

                Note: If you are using tasks that use the Fargate launch type, the add parameter is not supported.

                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 the Create a container section of the Docker Remote API and the --device option to docker run.

              Note: If you are using tasks that use the Fargate launch type, the devices parameter is not 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 | grep "Server API version"

            • 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.

          • disableNetworking — (Boolean)

            When this parameter is true, networking is disabled within the container. This parameter maps to NetworkDisabled in the Create a container section of the Docker Remote API.

            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 Create a container section of the Docker Remote API and the --privileged option to docker run.

            Note: This parameter is not supported for Windows containers or tasks using the Fargate launch type.
          • 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 Create a container section of the Docker Remote API 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 Create a container section of the Docker Remote API and the --dns option to docker run.

            Note: This parameter is not supported for Windows containers.
          • dnsSearchDomains — (Array<String>)

            A list of DNS search domains that are presented to the container. This parameter maps to DnsSearch in the Create a container section of the Docker Remote API and the --dns-search option to docker run.

            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. If using the Fargate launch type, this may be used to list non-Fargate hosts to which the container can talk. This parameter maps to ExtraHosts in the Create a container section of the Docker Remote API and the --add-host option to docker run.

            Note: This parameter is not supported for Windows containers.
            • 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 labels for SELinux and AppArmor multi-level security systems. This field is not valid for containers in tasks using the Fargate launch type.

            This parameter maps to SecurityOpt in the Create a container section of the Docker Remote API 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. This parameter is not supported for Windows containers.
          • interactive — (Boolean)

            When this parameter is true, this allows you to deploy containerized applications that require stdin or a tty to be allocated. This parameter maps to OpenStdin in the Create a container section of the Docker Remote API and the --interactive option to docker run.

          • pseudoTerminal — (Boolean)

            When this parameter is true, a TTY is allocated. This parameter maps to Tty in the Create a container section of the Docker Remote API 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 Create a container section of the Docker Remote API 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 | grep "Server API version"

          • ulimits — (Array<map>)

            A list of ulimits to set in the container. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type. 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 | grep "Server API version"

            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"
              • "nice"
              • "nofile"
              • "nproc"
              • "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.

            If using the Fargate launch type, the only supported value is awslogs.

            This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses; however the container may 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). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

            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 | grep "Server API version"

            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. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default. If using the Fargate launch type, the only supported value is awslogs. For more information about using the awslogs driver, see Using the awslogs Log Driver in the Amazon Elastic Container Service Developer Guide.

              Note: If you have a custom driver that is not listed above that you would like to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that is 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, Amazon Web Services does not currently support running modified copies of this software.

              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 | grep "Server API version"

              Possible values include:
              • "json-file"
              • "syslog"
              • "journald"
              • "gelf"
              • "fluentd"
              • "awslogs"
              • "splunk"
            • 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 | grep "Server API version"

          • healthCheck — (map)

            The health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API 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 execute the command arguments directly, or CMD-SHELL to run the command with the container's default shell. For example:

              [ "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 the Create a container section of the Docker Remote API.

            • 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 within which to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You may specify between 0 and 300 seconds. The startPeriod is disabled by default.

              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 the Create a container section of the Docker Remote API and the --sysctl option to docker run.

            Note: It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. When you do, the container that is started last will determine which systemControls parameters take effect.
            • namespace — (String)

              The namespaced kernel parameter to set a value for.

            • value — (String)

              The value for the namespaced kernel parameter specifed in namespace.

        • family — (String)

          The family of your task definition, used as the definition name.

        • taskRoleArn — (String)

          The ARN of the IAM role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role.

          IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code in order to take advantage of the feature. For more information, see Windows IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.

        • executionRoleArn — (String)

          The Amazon Resource Name (ARN) of the task execution role that the Amazon ECS container agent and the Docker daemon can assume.

        • networkMode — (String)

          The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. The default Docker network mode is bridge. If using the Fargate launch type, the awsvpc network mode is required. If using the EC2 launch type, any network mode can be used. If the network mode is set to none, you can't specify port mappings in your container definitions, and the task's 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.

          If the network mode is awsvpc, the task is allocated an Elastic Network Interface, and you must specify a NetworkConfiguration 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.

          Note: Currently, only the Amazon ECS-optimized AMI, other Amazon Linux variants with the ecs-init package, or AWS Fargate infrastructure support the awsvpc network mode.

          If the network mode is host, you can't run multiple instantiations of the same task on a single container instance when port mappings are used.

          Docker for Windows uses different network modes than Docker for Linux. When you register a task definition with Windows containers, you must not specify a network mode. If you use the console to register a task definition with Windows containers, you must choose the <default> network mode object.

          For more information, see Network settings in the Docker run reference.

          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 you register a new revision of a task definition in the same family, the revision value always increases by one (even if you have deregistered previous revisions in this family).

        • volumes — (Array<map>)

          The list of volumes in a task.

          If you are using the Fargate launch type, the host and sourcePath parameters are not supported.

          For more information about volume definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.

          • name — (String)

            The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints.

          • host — (map)

            This parameter is specified when using bind mount host volumes. Bind mount host volumes are supported when using either the EC2 or Fargate launch types. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it is stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume, but the data is not guaranteed to persist after the containers associated with it stop running.

            Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers cannot mount directories on a different drive, and mount point cannot 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 is 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 does not 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 are using the Fargate launch type, the sourcePath parameter is not supported.

          • dockerVolumeConfiguration — (map)

            This parameter is specified when using Docker volumes. Docker volumes are only supported when using the EC2 launch type. Windows containers only support the use of the local driver. To use bind mounts, specify a host instead.

            • scope — (String)

              The scope for the Docker volume which determines it's 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 does not 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. For more information, see Docker plugin discovery. This parameter maps to Driver in the Create a volume section of the Docker Remote API 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 Create a volume section of the Docker Remote API 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 Create a volume section of the Docker Remote API and the xxlabel option to docker volume create .

        • status — (String)

          The status of the task definition.

          Possible values include:
          • "ACTIVE"
          • "INACTIVE"
        • requiresAttributes — (Array<map>)

          The container instance attributes required by your task. This field is not valid if using the Fargate launch type for your task.

          • namerequired — (String)

            The name of the attribute. Up to 128 letters (uppercase and lowercase), numbers, hyphens, underscores, and periods are allowed.

          • value — (String)

            The value of the attribute. Up to 128 letters (uppercase and lowercase), numbers, hyphens, underscores, periods, at signs (@), forward slashes, colons, and spaces are allowed.

          • targetType — (String)

            The type of the target with which to attach the attribute. This parameter is required if you use the short form ID for a resource instead of the full ARN.

            Possible values include:
            • "container-instance"
          • targetId — (String)

            The ID of the target. You can specify the short form ID for a resource or the full Amazon Resource Name (ARN).

        • placementConstraints — (Array<map>)

          An array of placement constraint objects to use for tasks. This field is not valid if using the Fargate launch type for your task.

          • type — (String)

            The type of constraint. The DistinctInstance constraint ensures that each task in a particular group is running on a different container instance. The MemberOf constraint restricts selection to be from a group of valid candidates.

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

            A cluster query language expression to apply to the constraint. For more information, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide.

        • compatibilities — (Array<String>)

          The launch type to use with your task. For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide.

        • requiresCompatibilities — (Array<String>)

          The launch type the task is using.

        • cpu — (String)

          The number of cpu units used by the task. If using the EC2 launch type, this field is optional and any value can be used. If using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of valid values for the memory parameter:

          • 256 (.25 vCPU) - Available memory values: 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB)

          • 512 (.5 vCPU) - Available memory values: 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB)

          • 2048 (2 vCPU) - Available memory values: Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB)

          • 4096 (4 vCPU) - Available memory values: Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB)

        • memory — (String)

          The amount (in MiB) of memory used by the task. If using the EC2 launch type, this field is optional and any value can be used. If using the Fargate launch type, this field is required and you must use one of the following values, which 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)

          • 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) - Available cpu values: 1024 (1 vCPU)

          • Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) - Available cpu values: 2048 (2 vCPU)

          • Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) - Available cpu values: 4096 (4 vCPU)

Returns:

  • (AWS.Request)

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

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

Starts a new task using the specified task definition.

You can allow Amazon ECS to place tasks for you, or you can customize how Amazon ECS places tasks using placement constraints and placement strategies. For more information, see Scheduling Tasks in the Amazon Elastic Container Service Developer Guide.

Alternatively, you can use StartTask to use your own scheduler or place tasks manually on specific container instances.

The Amazon ECS API follows an eventual consistency model, due to the distributed nature of the system supporting the API. This means that the result of an API command you run that affects your Amazon ECS resources might not be immediately visible to all subsequent commands you run. You should keep this in mind when you carry out an API command that immediately follows a previous API command.

To manage eventual consistency, you can do the following:

  • Confirm the state of the resource before you run a command to modify it. Run the DescribeTasks command using an exponential backoff algorithm to ensure that you allow enough time for the previous command to propagate through the system. To do this, run the DescribeTasks command repeatedly, starting with a couple of seconds of wait time and increasing gradually up to five minutes of wait time.

  • Add wait time between subsequent commands, even if the DescribeTasks command returns an accurate response. Apply an exponential backoff algorithm starting with a couple of seconds of wait time, and increase gradually up to about five minutes of wait time.

        • "spread"
        • "binpack"
      • field — (String)

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

Stops a running task.

When StopTask is called on a task, the equivalent of docker stop is issued to the containers running in the task. This results in a SIGTERM and a default 30-second timeout, after which SIGKILL is sent and the containers are forcibly stopped. If the container handles the SIGTERM gracefully and exits within 30 seconds from receiving it, no SIGKILL is sent.

Note: The default 30-second timeout can be configured on the Amazon ECS container agent with the ECS_CONTAINER_STOP_TIMEOUT variable. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.

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

Modifies the status of an Amazon ECS container instance.

You can change the status of a container instance to DRAINING to manually remove an instance from a cluster, for example to perform system updates, update the Docker daemon, or scale down the cluster size.

When you set a container instance to DRAINING, Amazon ECS prevents new tasks from being scheduled for placement on the container instance and replacement service tasks are started on other container instances in the cluster if the resources are available. Service tasks on the container instance that are in the PENDING state are stopped immediately.

Service tasks on the container instance that are in the RUNNING state are stopped and replaced according to the service's deployment configuration parameters, minimumHealthyPercent and maximumPercent. You can change the deployment configuration of your service using UpdateService.

  • If minimumHealthyPercent is below 100%, the scheduler can ignore desiredCount temporarily during task replacement. For example, desiredCount is four tasks, a minimum of 50% allows the scheduler to stop two existing tasks before starting two new tasks. If the minimum is 100%, the service scheduler can't remove existing tasks until the replacement tasks are considered healthy. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state. Tasks for services that use a load balancer are considered healthy if they are in the RUNNING state and the container instance they are hosted on is reported as healthy by the load balancer.

  • The maximumPercent parameter represents an upper limit on the number of running tasks during task replacement, which enables you to define the replacement batch size. For example, if desiredCount of four tasks, a maximum of 200% starts four new tasks before stopping the four tasks to be drained (provided that the cluster resources required to do this are available). If the maximum is 100%, then replacement tasks can't start until the draining tasks have stopped.

Any PENDING or RUNNING tasks that do not belong to a service are not affected; you must wait for them to finish or stop them manually.

A container instance has completed draining when it has no more RUNNING tasks. You can verify this using ListTasks.

When you set a container instance to ACTIVE, the Amazon ECS scheduler can begin scheduling tasks on the instance again.

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

Modifies the desired count, deployment configuration, network configuration, or task definition used in a service.

You can add to or subtract from the number of instantiations of a task definition in a service by specifying the cluster that the service is running in and a new desiredCount parameter.

If you have updated the Docker image of your application, you can create a new task definition with that image and deploy it to your service. The service scheduler uses the minimum healthy percent and maximum percent parameters (in the service's deployment configuration) to determine the deployment strategy.

Note: If your updated Docker image uses the same tag as what is in the existing task definition for your service (for example, my_image:latest), you do not need to create a new revision of your task definition. You can update the service using the forceNewDeployment option. The new tasks launched by the deployment pull the current image/tag combination from your repository when they start.

You can also update the deployment configuration of a service. When a deployment is triggered by updating the task definition of a service, the service scheduler uses the deployment configuration parameters, minimumHealthyPercent and maximumPercent, to determine the deployment strategy.

  • If minimumHealthyPercent is below 100%, the scheduler can ignore desiredCount temporarily during a deployment. For example, if desiredCount is four tasks, a minimum of 50% allows the scheduler to stop two existing tasks before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state. Tasks for services that use a load balancer are considered healthy if they are in the RUNNING state and the container instance they are hosted on is reported as healthy by the load balancer.

  • The maximumPercent parameter represents an upper limit on the number of running tasks during a deployment, which enables you to define the deployment batch size. For example, if desiredCount is four tasks, a maximum of 200% starts four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available).

When UpdateService stops a task during a deployment, the equivalent of docker stop is issued to the containers running in the task. This results in a SIGTERM and a 30-second timeout, after which SIGKILL is sent and the containers are forcibly stopped. If the container handles the SIGTERM gracefully and exits within 30 seconds from receiving it, no SIGKILL is sent.

When the service scheduler launches new tasks, it determines task placement in your cluster with the following logic:

  • Determine which of the container instances in your cluster can support your service's task definition (for example, they have the required CPU, memory, ports, and container instance attributes).

  • By default, the service scheduler attempts to balance tasks across Availability Zones in this manner (although you can choose a different placement strategy):

    • Sort the valid container instances by the fewest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have zero, valid container instances in either zone B or C are considered optimal for placement.

    • Place the new service task on a valid container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the fewest number of running tasks for this service.

When the service scheduler stops running tasks, it attempts to maintain balance across the Availability Zones in your cluster using the following logic:

  • Sort the container instances by the largest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have two, container instances in either zone B or C are considered optimal for termination.

  • Stop the task on a container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the largest number of running tasks for this service.

});

Parameters:

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

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

    • service — (String)

      The name of the service to update.

    • desiredCount — (Integer)

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

    • taskDefinition — (String)

      The family and revision (family:revision) or full ARN of the task definition to run in your service. If a revision is not specified, the latest ACTIVE revision is used. If you modify the task definition with UpdateService, Amazon ECS spawns a task with the new version of the task definition and then stops an old task after the new version is running.

    • deploymentConfiguration — (map)

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

      • maximumPercent — (Integer)

        The upper limit (as a percentage of the service's desiredCount) of the number of tasks that are allowed in the RUNNING or PENDING state in a service during a deployment. The maximum number of tasks during a deployment is the desiredCount multiplied by maximumPercent/100, rounded down to the nearest integer value.

      • minimumHealthyPercent — (Integer)

        The lower limit (as a percentage of the service's desiredCount) of the number of running tasks that must remain in the RUNNING state in a service during a deployment. The minimum number of healthy tasks during a deployment is the desiredCount multiplied by minimumHealthyPercent/100, rounded up to the nearest integer value.

    • 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 is not supported for other network modes. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

      Note: Updating a service to add a subnet to a list of existing subnets does not trigger a service deployment. For example, if your network configuration change is to keep the existing subnets and simply add another subnet to the network configuration, this does not trigger a new service deployment.
      • awsvpcConfiguration — (map)

        The VPC subnets and security groups associated with a task.

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

          The subnets associated with the task or service. There is a limit of 16 subnets able to be specified per AwsVpcConfiguration.

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

          The security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is a limit of 5 security groups able to 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"
    • platformVersion — (String)

      The platform version that your service should run.

    • forceNewDeployment — (Boolean)

      Whether to force a new deployment of the service. Deployments are not forced by default. You can use this option to trigger a new deployment with no service definition changes. For example, you can update a service's tasks to use a newer Docker image with the same image/tag combination (my_image:latest) or to roll Fargate tasks onto a newer platform version.

    • healthCheckGracePeriodSeconds — (Integer)

      The period of time, in seconds, that the Amazon ECS service scheduler should ignore unhealthy Elastic Load Balancing target health checks after a task has first started. This is only valid if your service is configured to use a load balancer. 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 1,800 seconds during which the ECS service scheduler ignores the Elastic Load Balancing health check status. This grace period can prevent the ECS service scheduler from marking tasks as unhealthy and stopping them before they have time to come up.

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 update call.

        • serviceArn — (String)

          The ARN that identifies the service. The ARN contains the arn:aws:ecs namespace, followed by the Region of the service, the AWS account ID of the service owner, the service namespace, and then the service name. For example, arn:aws:ecs:region:012345678910:service/my-service .

        • serviceName — (String)

          The name of your service. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores 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.

        • 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, containing the load balancer name, the container name (as it appears in a container definition), and the container port to access from the load balancer.

          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 are not supported. Also, when you create any target groups for these services, you must choose ip as the target type, not instance, 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 associated with a service.

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

          • loadBalancerName — (String)

            The name of a load balancer.
