Overview
Constructs a service interface object. Each API operation is exposed as a function on service.
Service Description
Amazon Elastic Container Service (Amazon ECS) is a highly scalable, fast, container management service. It makes it easy to run, stop, and manage Docker containers. You can host your cluster on a serverless infrastructure that's managed by Amazon ECS by launching your services or tasks on Fargate. For more control, you can host your tasks on a cluster of Amazon Elastic Compute Cloud (Amazon EC2) or External (on-premises) instances that you manage.
Amazon ECS makes it easy to launch and stop container-based applications with simple API calls. This makes it easy to get the state of your cluster from a centralized service, and gives you access to many familiar Amazon EC2 features.
You can use Amazon ECS to schedule the placement of containers across your cluster based on your resource needs, isolation policies, and availability requirements. With Amazon ECS, you don't need to operate your own cluster management and configuration management systems. You also don't need to worry about scaling your management infrastructure.
Sending a Request Using ECS
var ecs = new AWS.ECS();
ecs.createCapacityProvider(params, function (err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});
Locking the API Version
In order to ensure that the ECS object uses this specific API, you can
construct the object by passing the apiVersion
option to the constructor:
var ecs = new AWS.ECS({apiVersion: '2014-11-13'});
You can also set the API version globally in AWS.config.apiVersions
using
the ecs service identifier:
AWS.config.apiVersions = {
ecs: '2014-11-13',
// other service API versions
};
var ecs = new AWS.ECS();

Property Details
Method Details
createCapacityProvider(params = {}, callback) ⇒ AWS.Request
Creates a new capacity provider. Capacity providers are associated with an Amazon ECS cluster and are used in capacity provider strategies to facilitate cluster auto scaling.
Only capacity providers that use an Auto Scaling group can be created. Amazon ECS tasks on Fargate use the
FARGATE
andFARGATE_SPOT
capacity providers. These providers are available to all accounts in the Amazon Web Services Regions that Fargate supports.Service Reference:
Examples:
Calling the createCapacityProvider operation
var params = { autoScalingGroupProvider: { /* required */ autoScalingGroupArn: 'STRING_VALUE', /* required */ managedDraining: ENABLED | DISABLED, managedScaling: { instanceWarmupPeriod: 'NUMBER_VALUE', maximumScalingStepSize: 'NUMBER_VALUE', minimumScalingStepSize: 'NUMBER_VALUE', status: ENABLED | DISABLED, targetCapacity: 'NUMBER_VALUE' }, managedTerminationProtection: ENABLED | DISABLED }, name: 'STRING_VALUE', /* required */ tags: [ { key: 'STRING_VALUE', value: 'STRING_VALUE' }, /* more items */ ] }; ecs.createCapacityProvider(params, function(err, data) { if (err) console.log(err, err.stack); // an error occurred else console.log(data); // successful response });
Parameters:
-
params
(Object)
(defaults to: {})
—
name
— (String
)The name of the capacity provider. Up to 255 characters are allowed. They include letters (both upper and lowercase letters), numbers, underscores (_), and hyphens (-). The name can't be prefixed with "
aws
", "ecs
", or "fargate
".autoScalingGroupProvider
— (map
)The details of the Auto Scaling group for the capacity provider.
autoScalingGroupArn
— required — (String
)The Amazon Resource Name (ARN) that identifies the Auto Scaling group, or the Auto Scaling group name.

)The managed scaling settings for the Auto Scaling group capacity provider.
status
— (String
)Determines whether to use managed scaling for the capacity provider.
Possible values include:"ENABLED"
"DISABLED"
targetCapacity
— (Integer
)The target capacity utilization as a percentage for the capacity provider. The specified value must be greater than
0
and less than or equal to100
. For example, if you want the capacity provider to maintain 10% spare capacity, then that means the utilization is 90%, so use atargetCapacity
of90
. The default value of100
percent results in the Amazon EC2 instances in your Auto Scaling group being completely used.minimumScalingStepSize
— (Integer
)The minimum number of Amazon EC2 instances that Amazon ECS will scale out at one time. The scale in process is not affected by this parameter If this parameter is omitted, the default value of
1
is used.When additional capacity is required, Amazon ECS will scale up the minimum scaling step size even if the actual demand is less than the minimum scaling step size.
If you use a capacity provider with an Auto Scaling group configured with more than one Amazon EC2 instance type or Availability Zone, Amazon ECS will scale up by the exact minimum scaling step size value and will ignore both the maximum scaling step size as well as the capacity demand.
maximumScalingStepSize
— (Integer
)The maximum number of Amazon EC2 instances that Amazon ECS will scale out at one time. The scale in process is not affected by this parameter. If this parameter is omitted, the default value of
10000
is used.instanceWarmupPeriod
— (Integer
)The period of time, in seconds, after a newly launched Amazon EC2 instance can contribute to CloudWatch metrics for Auto Scaling group. If this parameter is omitted, the default value of
300
seconds is used.

— (String
)The managed termination protection setting to use for the Auto Scaling group capacity provider. This determines whether the Auto Scaling group has managed termination protection. The default is off.
When using managed termination protection, managed scaling must also be used otherwise managed termination protection doesn't work.
When managed termination protection is on, Amazon ECS prevents the Amazon EC2 instances in an Auto Scaling group that contain tasks from being terminated during a scale-in action. The Auto Scaling group and each instance in the Auto Scaling group must have instance protection from scale-in actions on as well. For more information, see Instance Protection in the Auto Scaling User Guide.
When managed termination protection is off, your Amazon EC2 instances aren't protected from termination when the Auto Scaling group scales in.
Possible values include:"ENABLED"
"DISABLED"
managedDraining
— (String
)The managed draining option for the Auto Scaling group capacity provider. When you enable this, Amazon ECS manages and gracefully drains the EC2 container instances that are in the Auto Scaling group capacity provider.
Possible values include:"ENABLED"
"DISABLED"
tags

cluster when you launch your first container instance. However, you can create your own cluster with a unique name with theCreateCluster
action.Note: When you call the CreateCluster API operation, Amazon ECS attempts to create the Amazon ECS service-linked role for your account. This is so that it can manage required resources in other Amazon Web Services services on your behalf. However, if the user that makes the call doesn't have permissions to create the service-linked role, it isn't created. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.Service Reference:
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 = { capacityProviders: [ 'STRING_VALUE', /* more items */ ], clusterName: 'STRING_VALUE', configuration: { executeCommandConfiguration: { kmsKeyId: 'STRING_VALUE', logConfiguration: { cloudWatchEncryptionEnabled: true || false, cloudWatchLogGroupName: 'STRING_VALUE', s3BucketName: 'STRING_VALUE', s3EncryptionEnabled: true || false, s3KeyPrefix: 'STRING_VALUE' }, logging: NONE | DEFAULT | OVERRIDE }, managedStorageConfiguration: { fargateEphemeralStorageKmsKeyId: 'STRING_VALUE', kmsKeyId: 'STRING_VALUE' } }, defaultCapacityProviderStrategy: [ { capacityProvider: 'STRING_VALUE', /* required */ base: 'NUMBER_VALUE', weight: 'NUMBER_VALUE' }, /* more items */ ], serviceConnectDefaults: { namespace: 'STRING_VALUE' /* required */ }, settings: [ { name: containerInsights, value: 'STRING_VALUE' }, /* more items */ ], tags: [ { key: 'STRING_VALUE', value: 'STRING_VALUE' }, /* more items */ ] }; ecs.createCluster(params, function(err, data) { if (err) console.log(err, err.stack); // an error occurred else console.log(data); // successful response });
Parameters:

For each resource, each tag key must be unique, and each tag key can have only one value.
-
Maximum key length - 128 Unicode characters in UTF-8
-
Maximum value length - 256 Unicode characters in UTF-8
-
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
-
Tag keys and values are case-sensitive.
-
Do not use
aws:
,AWS:
, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
key
— (String
)One part of a key-value pair that make up a tag. A
key
is a general label that acts like a category for more specific tag values.value
— (String
)The optional part of a key-value pair that make up a tag. A
value
acts as a descriptor within a tag category (key).
-

containerInsights
value set with PutAccountSetting or PutAccountSettingDefault.name
— (String
)The name of the cluster setting. The value is
Possible values include:containerInsights
."containerInsights"
value
— (String
)The value to set for the cluster setting. The supported values are
enabled
anddisabled
.If you set
name
tocontainerInsights
andvalue
toenabled
, CloudWatch Container Insights will be on for the cluster, otherwise it will be off unless thecontainerInsights
account setting is turned on. If a cluster value is specified, it will override thecontainerInsights
value set with PutAccountSetting or PutAccountSettingDefault.
configuration
— (map
)The
execute
command configuration for the cluster.executeCommandConfiguration
— (map
)The details of the execute command configuration.
kmsKeyId
— (String
)Specify an Key Management Service key ID to encrypt the data between the local client and the container.
logging
— (String
)The log setting to use for redirecting logs for your execute command results. The following log settings are available.
-
NONE
: The execute command session is not logged. -
DEFAULT
: Theawslogs
configuration in the task definition is used. If no logging parameter is specified, it defaults to this value. If noawslogs
log driver is configured in the task definition, the output won't be logged. -
OVERRIDE
: Specify the logging details as a part oflogConfiguration
. If theOVERRIDE
logging option is specified, thelogConfiguration
is required.
"NONE"
"DEFAULT"
"OVERRIDE"
-
logConfiguration
— (map
)The log configuration for the results of the execute command actions. The logs can be sent to CloudWatch Logs or an Amazon S3 bucket. When
logging=OVERRIDE
is specified, alogConfiguration
must be provided.cloudWatchLogGroupName
— (String
)The name of the CloudWatch log group to send logs to.
Note: The CloudWatch log group must already be created.cloudWatchEncryptionEnabled
— (Boolean
)Determines whether to use encryption on the CloudWatch logs. If not specified, encryption will be off.

— (String
)The name of the S3 bucket to send logs to.
Note: The S3 bucket must already be created.s3EncryptionEnabled
— (Boolean
)Determines whether to use encryption on the S3 logs. If not specified, encryption is not used.
s3KeyPrefix
— (String
)An optional folder in the S3 bucket to place logs in.
managedStorageConfiguration
— (map
)The details of the managed storage configuration.
kmsKeyId
— (String
)Specify a Key Management Service key ID to encrypt the managed storage.
fargateEphemeralStorageKmsKeyId
— (String
)Specify the Key Management Service key ID for the Fargate ephemeral storage.
capacityProviders
— (Array<String>
)The short name of one or more capacity providers to associate with the cluster. A capacity provider must be associated with a cluster before it can be included as part of the default capacity provider strategy of the cluster or used in a capacity provider strategy when calling the CreateService or RunTask actions.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must be created but not associated with another cluster. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the
FARGATE
orFARGATE_SPOT
capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.The PutCapacityProvider API operation is used to update the list of available capacity providers for a cluster after the cluster is created.
defaultCapacityProviderStrategy
— (Array<map>
)The capacity provider strategy to set as the default for the cluster. After a default capacity provider strategy is set for a cluster, when you call the CreateService or RunTask APIs with no capacity provider strategy or launch type specified, the default capacity provider strategy for the cluster is used.
If a default capacity provider strategy isn't defined for a cluster when it was created, it can be defined later with the PutClusterCapacityProviders API operation.
capacityProvider
— required — (String
)The short name of the capacity provider.
weight
— (Integer
)The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The
weight
value is taken into consideration after thebase
value, if defined, is satisfied.If no
weight
value is specified, the default value of0
is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of0
can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService
actions using the capacity provider strategy will fail.An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of
1
, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base
— (Integer
)The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of
0
is used.
serviceConnectDefaults
— (map
)Use this parameter to set a default Service Connect namespace. After you set a default Service Connect namespace, any new services with Service Connect turned on that are created in the cluster are added as client services in the namespace. This setting only applies to new services that set the
enabled
parameter totrue
in theServiceConnectConfiguration
. You can set the namespace of each service individually in theServiceConnectConfiguration
to override this default parameter.Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
namespace
— required — (String
)The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace that's used when you create a service and don't specify a Service Connect configuration. The namespace name can include up to 1024 characters. The name is case-sensitive. The name can't include hyphens (-), tilde (~), greater than (>), less than (<), or slash (/).
If you enter an existing namespace name or ARN, then that namespace will be used. Any namespace type is supported. The namespace must be in this account and this Amazon Web Services Region.
If you enter a new name, a Cloud Map namespace will be created. Amazon ECS creates a Cloud Map namespace with the "API calls" method of instance discovery only. This instance discovery method is the "HTTP" namespace type in the Command Line Interface. Other types of instance discovery aren't used by Service Connect.
If you update the cluster with an empty string
""
for the namespace name, the cluster configuration for Service Connect is removed. Note that the namespace will remain in Cloud Map and must be deleted separately.For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide.
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.

Returns:
createService(params = {}, callback) ⇒ AWS.Request
Runs and maintains your desired number of tasks from a specified task definition. If the number of tasks running in a service drops below the
desiredCount
, Amazon ECS runs another copy of the task in the specified cluster. To update an existing service, see the UpdateService action.Note: On March 21, 2024, a change was made to resolve the task definition revision before authorization. When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.In addition to maintaining the desired count of tasks in your service, you can optionally run your service behind one or more load balancers. The load balancers distribute traffic across the tasks that are associated with the service. For more information, see Service load balancing in the Amazon Elastic Container Service Developer Guide.
You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when creating or updating a service.
volumeConfigurations
is only supported for REPLICA service and not DAEMON service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.Tasks for services that don't use a load balancer are considered healthy if they're in the
RUNNING
state. Tasks for services that use a load balancer are considered healthy if they're in theRUNNING
state and are reported as healthy by the load balancer.There are two service scheduler strategies available:
-
REPLICA
- The replica scheduling strategy places and maintains your desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. For more information, see Service scheduler concepts in the Amazon Elastic Container Service Developer Guide. -
DAEMON
- The daemon scheduling strategy deploys exactly one task on each active container instance that meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It also stops tasks that don't meet the placement constraints. When using this strategy, you don't need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies. For more information, see Service scheduler concepts in the Amazon Elastic Container Service Developer Guide.
You can optionally specify a deployment configuration for your service. The deployment is initiated by changing properties. For example, the deployment might be initiated by the task definition or by your desired count of a service. This is done with an UpdateService operation. The default value for a replica service for
minimumHealthyPercent
is 100%. The default value for a daemon service forminimumHealthyPercent
is 0%.If a service uses the
ECS
deployment controller, the minimum healthy percent represents a lower limit on the number of tasks in a service that must remain in theRUNNING
state during a deployment. Specifically, it represents it as a percentage of your desired number of tasks (rounded up to the nearest integer). This happens when any of your container instances are in theDRAINING
state if the service contains tasks using the EC2 launch type. Using this parameter, you can deploy without using additional cluster capacity. For example, if you set your service to have desired number of four tasks and a minimum healthy percent of 50%, the scheduler might stop two existing tasks to free up cluster capacity before starting two new tasks. If they're in theRUNNING
state, tasks for services that don't use a load balancer are considered healthy . If they're in theRUNNING
state and reported as healthy by the load balancer, tasks for services that do use a load balancer are considered healthy . The default value for minimum healthy percent is 100%.If a service uses the
ECS
deployment controller, the maximum percent parameter represents an upper limit on the number of tasks in a service that are allowed in theRUNNING
orPENDING
state during a deployment. Specifically, it represents it as a percentage of the desired number of tasks (rounded down to the nearest integer). This happens when any of your container instances are in theDRAINING
state if the service contains tasks using the EC2 launch type. Using this parameter, you can define the deployment batch size. For example, if your service has a desired number of four tasks and a maximum percent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default value for maximum percent is 200%.If a service uses either the
CODE_DEPLOY
orEXTERNAL
deployment controller types and tasks that use the EC2 launch type, the minimum healthy percent and maximum percent values are used only to define the lower and upper limit on the number of the tasks in the service that remain in theRUNNING
state. This is while the container instances are in theDRAINING
state. If the tasks in the service use the Fargate launch type, the minimum healthy percent and maximum percent values aren't used. This is the case even if they're currently visible when describing your service.When creating a service that uses the
EXTERNAL
deployment controller, you can specify only parameters that aren't controlled at the task set level. The only required parameter is the service name. You control your services using the CreateTaskSet operation. For more information, see Amazon ECS deployment types in the Amazon Elastic Container Service Developer Guide.When the service scheduler launches new tasks, it determines task placement. For information about task placement and task placement strategies, see Amazon ECS task placement in the Amazon Elastic Container Service Developer Guide
Starting April 15, 2023, Amazon Web Services will not onboard new customers to Amazon Elastic Inference (EI), and will help current customers migrate their workloads to options that offer better price and performance. After April 15, 2023, new customers will not be able to launch instances with Amazon EI accelerators in Amazon SageMaker, Amazon ECS, or Amazon EC2. However, customers who have used Amazon EI at least once during the past 30-day period are considered current customers and will be able to continue using the service.

Parameters:
-
params
(Object)
(defaults to: {})
—
cluster
— (String
)The short name or full Amazon Resource Name (ARN) of the cluster that you run your service on. If you do not specify a cluster, the default cluster is assumed.
serviceName
— (String
)The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster, but you can have similarly named services in multiple clusters within a Region or across multiple Regions.
taskDefinition
— (String
)The
family
andrevision
(family:revision
) or full ARN of the task definition to run in your service. If arevision
isn't specified, the latestACTIVE
revision is used.A task definition must be specified if the service uses either the
ECS
orCODE_DEPLOY
deployment controllers.For more information about deployment types, see Amazon ECS deployment types.
loadBalancers
— (Array<map>
)A load balancer object representing the load balancers to use with your service. For more information, see Service load balancing in the Amazon Elastic Container Service Developer Guide.
If the service uses the rolling update (
ECS
) deployment controller and using either an Application Load Balancer or Network Load Balancer, you must specify one or more target group ARNs to attach to the service. The service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.If the service uses the
CODE_DEPLOY
deployment controller, the service is required to use either an Application Load Balancer or Network Load Balancer. When creating an CodeDeploy deployment group, you specify two target groups (referred to as atargetGroupPair
). During a deployment, CodeDeploy determines which task set in your service has the statusPRIMARY
, and it associates one target group with it. Then, it also associates the other target group with the replacement task set. The load balancer can also have up to two listeners: a required listener for production traffic and an optional listener that you can use to perform validation tests with Lambda functions before routing production traffic to it.If you use the
CODE_DEPLOY
deployment controller, these values can be changed when updating the service.For Application Load Balancers and Network Load Balancers, this object must contain the load balancer target group ARN, the container name, and the container port to access from the load balancer. The container name must be as it appears in a container definition. The load balancer name parameter must be omitted. When a task from this service is placed on a container instance, the container instance and port combination is registered as a target in the target group that's specified here.
For Classic Load Balancers, this object must contain the load balancer name, the container name , and the container port to access from the load balancer. The container name must be as it appears in a container definition. The target group ARN parameter must be omitted. When a task from this service is placed on a container instance, the container instance is registered with the load balancer that's specified here.
Services with tasks that use the
awsvpc
network mode (for example, those with the Fargate launch type) only support Application Load Balancers and Network Load Balancers. Classic Load Balancers aren't supported. Also, when you create any target groups for these services, you must chooseip
as the target type, notinstance
. This is because tasks that use theawsvpc
network mode are associated with an elastic network interface, not an Amazon EC2 instance.targetGroupArn
— (String
)The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.
For services using the
ECS
deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.For services using the
CODE_DEPLOY
deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.If your service's task definition uses the
awsvpc
network mode, you must chooseip
as the target type, notinstance
. Do this when creating your target groups because tasks that use theawsvpc
network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.loadBalancerName
— (String
)The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName
— (String
)The name of the container (as it appears in a container definition) to associate with the load balancer.
You need to specify the container name when configuring the target group for an Amazon ECS load balancer.
containerPort
— (Integer
)The port on the container to associate with the load balancer. This port must correspond to a
containerPort
in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on thehostPort
of the port mapping.
serviceRegistries
— (Array<map>
)The details of the service discovery registry to associate with this service. For more information, see Service discovery.
Note: Each service may be associated with one service registry. Multiple service registries for each service isn't supported.registryArn
— (String
)The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.
port
— (Integer
)The port value used if your service discovery service specified an SRV record. This field might be used if both the
awsvpc
network mode and SRV records are used.containerName
— (String
)The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the
bridge
orhost
network mode, you must specify acontainerName
andcontainerPort
combination from the task definition. If the task definition that your service task specifies uses theawsvpc
network mode and a type SRV DNS record is used, you must specify either acontainerName
andcontainerPort
combination or aport
value. However, you can't specify both.containerPort
— (Integer
)The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the
bridge
orhost
network mode, you must specify acontainerName
andcontainerPort
combination from the task definition. If the task definition your service task specifies uses theawsvpc
network mode and a type SRV DNS record is used, you must specify either acontainerName
andcontainerPort
combination or aport
value. However, you can't specify both.
desiredCount
— (Integer
)The number of instantiations of the specified task definition to place and keep running in your service.
This is required if
schedulingStrategy
isREPLICA
or isn't specified. IfschedulingStrategy
isDAEMON
then this isn't required.clientToken
— (String
)An identifier that you provide to ensure the idempotency of the request. It must be unique and is case sensitive. Up to 36 ASCII characters in the range of 33-126 (inclusive) are allowed.
launchType
— (String
)The infrastructure that you run your service on. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.
The
FARGATE
launch type runs your tasks on Fargate On-Demand infrastructure.Note: Fargate Spot infrastructure is available for use but a capacity provider strategy must be used. For more information, see Fargate capacity providers in the Amazon ECS Developer Guide.The
EC2
launch type runs your tasks on Amazon EC2 instances registered to your cluster.The
EXTERNAL
launch type runs your tasks on your on-premises server or virtual machine (VM) capacity registered to your cluster.A service can use either a launch type or a capacity provider strategy. If a
Possible values include:launchType
is specified, thecapacityProviderStrategy
parameter must be omitted."EC2"
"FARGATE"
"EXTERNAL"
capacityProviderStrategy
— (Array<map>
)The capacity provider strategy to use for the service.
If a
capacityProviderStrategy
is specified, thelaunchType
parameter must be omitted. If nocapacityProviderStrategy
orlaunchType
is specified, thedefaultCapacityProviderStrategy
for the cluster is used.A capacity provider strategy may contain a maximum of 6 capacity providers.
capacityProvider
— required — (String
)The short name of the capacity provider.
weight
— (Integer
)The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The
weight
value is taken into consideration after thebase
value, if defined, is satisfied.If no
weight
value is specified, the default value of0
is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of0
can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService
actions using the capacity provider strategy will fail.An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of
1
, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base
— (Integer
)The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of
0
is used.
platformVersion
— (String
)The platform version that your tasks in the service are running on. A platform version is specified only for tasks using the Fargate launch type. If one isn't specified, the
LATEST
platform version is used. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.role
— (String
)The name or full Amazon Resource Name (ARN) of the IAM role that allows Amazon ECS to make calls to your load balancer on your behalf. This parameter is only permitted if you are using a load balancer with your service and your task definition doesn't use the
awsvpc
network mode. If you specify therole
parameter, you must also specify a load balancer object with theloadBalancers
parameter.If your account has already created the Amazon ECS service-linked role, that role is used for your service unless you specify a role here. The service-linked role is required if your task definition uses the
awsvpc
network mode or if the service is configured to use service discovery, an external deployment controller, multiple target groups, or Elastic Inference accelerators in which case you don't specify a role here. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.If your specified role has a path other than
/
, then you must either specify the full role ARN (this is recommended) or prefix the role name with the path. For example, if a role with the namebar
has a path of/foo/
then you would specify/foo/bar
as the role name. For more information, see Friendly names and paths in the IAM User Guide.deploymentConfiguration
— (map
)Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker
— (map
)Note: The deployment circuit breaker can only be used for services using the rolling update (ECS
) deployment type.The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable
— required — (Boolean
)Determines whether to use the deployment circuit breaker logic for the service.
rollback
— required — (Boolean
)Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, themaximumPercent
parameter represents an upper limit on the number of your service's tasks that are allowed in theRUNNING
orPENDING
state during a deployment, as a percentage of thedesiredCount
(rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using theREPLICA
service scheduler and has adesiredCount
of four tasks and amaximumPercent
value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The defaultmaximumPercent
value for a service using theREPLICA
service scheduler is 200%.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.minimumHealthyPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, theminimumHealthyPercent
represents a lower limit on the number of your service's tasks that must remain in theRUNNING
state during a deployment, as a percentage of thedesiredCount
(rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has adesiredCount
of four tasks and aminimumHealthyPercent
of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.For services that do not use a load balancer, the following should be noted:
-
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
-
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a
RUNNING
state before the task is counted towards the minimum healthy percent total. -
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services that do use a load balancer, the following should be noted:
-
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
-
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
The default value for a replica service for
minimumHealthyPercent
is 100%. The defaultminimumHealthyPercent
value for a service using theDAEMON
service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.The minimum number of healthy tasks during a deployment is the
desiredCount
multiplied by theminimumHealthyPercent
/100, rounded up to the nearest integer value.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If a service is using either the blue/green (CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.-
alarms
— (map
)Information about the CloudWatch alarms.
alarmNames
— required — (Array<String>
)One or more CloudWatch alarm names. Use a "," to separate the alarms.
enable
— required — (Boolean
)Determines whether to use the CloudWatch alarm option in the service deployment process.
rollback
— required — (Boolean
)Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is used, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
placementConstraints
— (Array<map>
)An array of placement constraint objects to use for tasks in your service. You can specify a maximum of 10 constraints for each task. This limit includes constraints in the task definition and those specified at runtime.
type
— (String
)The type of constraint. Use
Possible values include:distinctInstance
to ensure that each task in a particular group is running on a different container instance. UsememberOf
to restrict the selection to a group of valid candidates."distinctInstance"
"memberOf"
expression
— (String
)A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is
distinctInstance
. For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide.
placementStrategy
— (Array<map>
)The placement strategy objects to use for tasks in your service. You can specify a maximum of 5 strategy rules for each service.
type
— (String
)The type of placement strategy. The
Possible values include:random
placement strategy randomly places tasks on available candidates. Thespread
placement strategy spreads placement across available candidates evenly based on thefield
parameter. Thebinpack
strategy places tasks on available candidates that have the least available amount of the resource that's specified with thefield
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."random"
"spread"
"binpack"
field
— (String
)The field to apply the placement strategy against. For the
spread
placement strategy, valid values areinstanceId
(orhost
, which has the same effect), or any platform or custom attribute that's applied to a container instance, such asattribute:ecs.availability-zone
. For thebinpack
placement strategy, valid values arecpu
andmemory
. For therandom
placement strategy, this field is not used.
networkConfiguration
— (map
)The network configuration for the service. This parameter is required for task definitions that use the
awsvpc
network mode to receive their own elastic network interface, and it isn't supported for other network modes. For more information, see Task networking in the Amazon Elastic Container Service Developer Guide.awsvpcConfiguration
— (map
)The VPC subnets and security groups that are associated with a task.
Note: All specified subnets and security groups must be from the same VPC.subnets
— required — (Array<String>
)The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per
AwsVpcConfiguration
.Note: All specified subnets must be from the same VPC.securityGroups
— (Array<String>
)The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per
AwsVpcConfiguration
.Note: All specified security groups must be from the same VPC.assignPublicIp
— (String
)Whether the task's elastic network interface receives a public IP address. The default value is
Possible values include:DISABLED
."ENABLED"
"DISABLED"
healthCheckGracePeriodSeconds
— (Integer
)The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started. This is only used when your service is configured to use a load balancer. If your service has a load balancer defined and you don't specify a health check grace period value, the default value of
0
is used.If you do not use an Elastic Load Balancing, we recommend that you use the
startPeriod
in the task definition health check parameters. For more information, see Health check.If your service's tasks take a while to start and respond to Elastic Load Balancing health checks, you can specify a health check grace period of up to 2,147,483,647 seconds (about 69 years). During that time, the Amazon ECS service scheduler ignores health check status. This grace period can prevent the service scheduler from marking tasks as unhealthy and stopping them before they have time to come up.
schedulingStrategy
— (String
)The scheduling strategy to use for the service. For more information, see Services.
There are two service scheduler strategies available:
-
REPLICA
-The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. This scheduler strategy is required if the service uses theCODE_DEPLOY
orEXTERNAL
deployment controller types. -
DAEMON
-The daemon scheduling strategy deploys exactly one task on each active container instance that meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks and will stop tasks that don't meet the placement constraints. When you're using this strategy, you don't need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies.Note: Tasks using the Fargate launch type or theCODE_DEPLOY
orEXTERNAL
deployment controller types don't support theDAEMON
scheduling strategy.
"REPLICA"
"DAEMON"
-
deploymentController
— (map
)The deployment controller to use for the service. If no deployment controller is specified, the default value of
ECS
is used.type
— required — (String
)The deployment controller type to use.
There are three deployment controller types available:
- ECS
-
The rolling update (
ECS
) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration. - CODE_DEPLOY
-
The blue/green (
CODE_DEPLOY
) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it. - EXTERNAL
-
The external (
EXTERNAL
) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.
"ECS"
"CODE_DEPLOY"
"EXTERNAL"
tags
— (Array<map>
)The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define. When a service is deleted, the tags are deleted as well.
The following basic restrictions apply to tags:
-
Maximum number of tags per resource - 50
-
For each resource, each tag key must be unique, and each tag key can have only one value.
-
Maximum key length - 128 Unicode characters in UTF-8
-
Maximum value length - 256 Unicode characters in UTF-8
-
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
-
Tag keys and values are case-sensitive.
-
Do not use
aws:
,AWS:
, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
key
— (String
)One part of a key-value pair that make up a tag. A
key
is a general label that acts like a category for more specific tag values.value
— (String
)The optional part of a key-value pair that make up a tag. A
value
acts as a descriptor within a tag category (key).
-
enableECSManagedTags
— (Boolean
)Specifies whether to turn on Amazon ECS managed tags for the tasks within the service. For more information, see Tagging your Amazon ECS resources in the Amazon Elastic Container Service Developer Guide.
When you use Amazon ECS managed tags, you need to set the
propagateTags
request parameter.propagateTags
— (String
)Specifies whether to propagate the tags from the task definition to the task. If no value is specified, the tags aren't propagated. Tags can only be propagated to the task during task creation. To add tags to a task after task creation, use the TagResource API action.
You must set this to a value other than
NONE
when you use Cost Explorer. For more information, see Amazon ECS usage reports in the Amazon Elastic Container Service Developer Guide.The default is
Possible values include:NONE
."TASK_DEFINITION"
"SERVICE"
"NONE"
enableExecuteCommand
— (Boolean
)Determines whether the execute command functionality is turned on for the service. If
true
, this enables execute command functionality on all containers in the service tasks.serviceConnectConfiguration
— (map
)The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
enabled
— required — (Boolean
)Specifies whether to use Service Connect with this service.
namespace
— (String
)The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace for use with Service Connect. The namespace must be in the same Amazon Web Services Region as the Amazon ECS service and cluster. The type of namespace doesn't affect Service Connect. For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide.
services

)The list of Service Connect service objects. These are names and aliases (also known as endpoints) that are used by other Amazon ECS services to connect to this service.
This field is not required for a "client" Amazon ECS service that's a member of a namespace only to connect to other services within the namespace. An example of this would be a frontend application that accepts incoming requests from either a load balancer that's attached to the service or by other means.
An object selects a port from the task definition, assigns a name for the Cloud Map service, and a list of aliases (endpoints) and ports for client applications to refer to this service.

.clientAliases
— (Array<map>
)The list of client aliases for this Service Connect service. You use these to assign names that can be used by client applications. The maximum number of client aliases that you can have in this list is 1.
Each alias ("endpoint") is a fully-qualified name and port number that other Amazon ECS tasks ("clients") can use to connect to this service.
Each name and port mapping must be unique within the namespace.
For each
ServiceConnectService
, you must provide at least oneclientAlias
with oneport
.port
— required — (Integer
)The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.
To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
dnsName
— (String
)The
dnsName
is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.If this parameter isn't specified, the default value of
discoveryName.namespace
is used. If thediscoveryName
isn't specified, the port mapping name from the task definition is used inportName.namespace
.To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are
database
,db
, or the lowercase name of a database, such asmysql
orredis
. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
ingressPortOverride
— (Integer
)The port number for the Service Connect proxy to listen on.
Use the value of this field to bypass the proxy for traffic on the port number specified in the named
portMapping
in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.In
awsvpc
mode and Fargate, the default value is the container port number. The container port number is in theportMapping
in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.timeout
— (map
)A reference to an object that represents the configured timeouts for Service Connect.
idleTimeoutSeconds
— (Integer
)The amount of time in seconds a connection will stay active while idle. A value of

Understand the following when specifying a log configuration for your containers.
-
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent.
For tasks on Fargate, the supported log drivers are
awslogs
,splunk
, andawsfirelens
.For tasks hosted on Amazon EC2 instances, the supported log drivers are
awslogs
,fluentd
,gelf
,json-file
,journald
,syslog
,splunk
, andawsfirelens
. -
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
-
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the
ECS_AVAILABLE_LOGGING_DRIVERS
environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide. -
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.
logDriver
— required — (String
)The log driver to use for the container.
For tasks on Fargate, the supported log drivers are
awslogs
,splunk
, andawsfirelens
.For tasks hosted on Amazon EC2 instances, the supported log drivers are
awslogs
,fluentd
,gelf
,json-file
,journald
,syslog
,splunk
, andawsfirelens
.For more information about using the
awslogs
log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.For more information about using the
awsfirelens
log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.Possible values include:"json-file"
"syslog"
"journald"
"gelf"
"fluentd"
"awslogs"
"splunk"
"awsfirelens"
options

— (String
)The Amazon Resource Name (ARN) identifier of the Amazon Web Services Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no Amazon Web Services Key Management Service key is specified, the default Amazon Web Services managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the
KmsKeyId
parameter of the CreateVolume API in the Amazon EC2 API Reference.Amazon Web Services authenticates the Amazon Web Services Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails.

deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.For services using the
CODE_DEPLOY
deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.If your service's task definition uses the
awsvpc
network mode, you must chooseip
as the target type, notinstance
. Do this when creating your target groups because tasks that use theawsvpc
network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.loadBalancerName
— (String
)The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName

)The name of the container (as it appears in a container definition) to associate with the load balancer.
You need to specify the container name when configuring the target group for an Amazon ECS load balancer.
containerPort
— (Integer
)The port on the container to associate with the load balancer. This port must correspond to a
containerPort
in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on thehostPort

)The details for the service discovery registries to assign to this service. For more information, see Service Discovery.
registryArn
— (String
)The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.

— (Integer
)The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the
bridge
orhost
network mode, you must specify acontainerName
andcontainerPort
combination from the task definition. If the task definition your service task specifies uses theawsvpc
network mode and a type SRV DNS record is used, you must specify either acontainerName
andcontainerPort

)The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
capacityProvider
— required — (String
)The short name of the capacity provider.
weight
— (Integer
)The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The
weight
value is taken into consideration after thebase
value, if defined, is satisfied.If no
weight
value is specified, the default value of0
is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of0
can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService
actions using the capacity provider strategy will fail.An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of
1
, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base
— (Integer
)The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of
0
is used.

)The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.
All tasks that run as part of this service must use the same
platformFamily
value as the service (for example,LINUX
).taskDefinition
— (String
)The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
deploymentConfiguration
— (map
)Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker
— (map
)Note: The deployment circuit breaker can only be used for services using the rolling update (ECS
) deployment type.The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable
— required — (Boolean
)Determines whether to use the deployment circuit breaker logic for the service.
rollback
— required — (Boolean
)Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, themaximumPercent
parameter represents an upper limit on the number of your service's tasks that are allowed in theRUNNING
orPENDING
state during a deployment, as a percentage of thedesiredCount
(rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using theREPLICA
service scheduler and has adesiredCount
of four tasks and amaximumPercent
value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The defaultmaximumPercent
value for a service using theREPLICA
service scheduler is 200%.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.minimumHealthyPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, theminimumHealthyPercent
represents a lower limit on the number of your service's tasks that must remain in theRUNNING
state during a deployment, as a percentage of thedesiredCount
(rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has adesiredCount
of four tasks and aminimumHealthyPercent
of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.For services that do not use a load balancer, the following should be noted:
-
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
-
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a
RUNNING
state before the task is counted towards the minimum healthy percent total. -
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services that do use a load balancer, the following should be noted:
-
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
-
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
The default value for a replica service for
minimumHealthyPercent
is 100%. The defaultminimumHealthyPercent
value for a service using theDAEMON
service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.The minimum number of healthy tasks during a deployment is the
desiredCount
multiplied by theminimumHealthyPercent
/100, rounded up to the nearest integer value.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If a service is using either the blue/green (CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.-

value is taken into consideration after thebase
value, if defined, is satisfied.If no
weight
value is specified, the default value of0

, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base

-
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the
ECS_AVAILABLE_LOGGING_DRIVERS
environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide. -
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

capacity providers are reserved and can't be deleted. You can disassociate them from a cluster using either the PutClusterCapacityProviders API or by deleting the cluster.Prior to a capacity provider being deleted, the capacity provider must be removed from the capacity provider strategy from all services. The UpdateService API can be used to remove a capacity provider from a service's capacity provider strategy. When updating a service, the
forceNewDeployment
option can be used to ensure that any tasks using the Amazon EC2 instance capacity provided by the capacity provider are transitioned to use the capacity from the remaining capacity providers. Only capacity providers that aren't associated with a cluster can be deleted. To remove a capacity provider from a cluster, you can either use PutClusterCapacityProviders or delete the cluster.Service Reference:
Examples:
Calling the deleteCapacityProvider operation

targetCapacity
— (Integer
)The target capacity utilization as a percentage for the capacity provider. The specified value must be greater than
0
and less than or equal to100
. For example, if you want the capacity provider to maintain 10% spare capacity, then that means the utilization is 90%, so use atargetCapacity
of90
. The default value of100
percent results in the Amazon EC2 instances in your Auto Scaling group being completely used.minimumScalingStepSize
— (Integer
)The minimum number of Amazon EC2 instances that Amazon ECS will scale out at one time. The scale in process is not affected by this parameter If this parameter is omitted, the default value of
1
is used.When additional capacity is required, Amazon ECS will scale up the minimum scaling step size even if the actual demand is less than the minimum scaling step size.
If you use a capacity provider with an Auto Scaling group configured with more than one Amazon EC2 instance type or Availability Zone, Amazon ECS will scale up by the exact minimum scaling step size value and will ignore both the maximum scaling step size as well as the capacity demand.
maximumScalingStepSize
— (Integer
)The maximum number of Amazon EC2 instances that Amazon ECS will scale out at one time. The scale in process is not affected by this parameter. If this parameter is omitted, the default value of
10000
is used.instanceWarmupPeriod

When using managed termination protection, managed scaling must also be used otherwise managed termination protection doesn't work.
When managed termination protection is on, Amazon ECS prevents the Amazon EC2 instances in an Auto Scaling group that contain tasks from being terminated during a scale-in action. The Auto Scaling group and each instance in the Auto Scaling group must have instance protection from scale-in actions on as well. For more information, see Instance Protection in the Auto Scaling User Guide.
When managed termination protection is off, your Amazon EC2 instances aren't protected from termination when the Auto Scaling group scales in.
Possible values include:"ENABLED"
"DISABLED"

Returns:
deleteService(params = {}, callback) ⇒ AWS.Request
Deletes a specified service within a cluster. You can delete a service if you have no running tasks in it and the desired task count is zero. If the service is actively maintaining tasks, you can't delete it, and you must update the service to a desired task count of zero. For more information, see UpdateService.
Note: When you delete a service, if there are still running tasks that require cleanup, the service status moves fromACTIVE
toDRAINING
, and the service is no longer visible in the console or in the ListServices API operation. After all tasks have transitioned to eitherSTOPPING
orSTOPPED
status, the service status moves fromDRAINING
toINACTIVE
. Services in theDRAINING
orINACTIVE
status can still be viewed with the DescribeServices API operation. However, in the future,INACTIVE
services may be cleaned up and purged from Amazon ECS record keeping, and DescribeServices calls on those services return aServiceNotFoundException
error.If you attempt to create a new service with the same name as an existing service in either
ACTIVE
orDRAINING
status, you receive an error.Service Reference:

in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on thehostPort
of the port mapping.
serviceRegistries
— (Array<map>
)The details for the service discovery registries to assign to this service. For more information, see Service Discovery.

— (Integer
)The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the
bridge
orhost
network mode, you must specify acontainerName
andcontainerPort
combination from the task definition. If the task definition your service task specifies uses theawsvpc
network mode and a type SRV DNS record is used, you must specify either acontainerName
andcontainerPort

— (String
)The status of the service. The valid values are
ACTIVE
,DRAINING
, orINACTIVE

)The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
capacityProvider
— required — (String
)The short name of the capacity provider.
weight
— (Integer
)The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The
weight
value is taken into consideration after thebase
value, if defined, is satisfied.If no
weight
value is specified, the default value of0
is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of0
can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService
actions using the capacity provider strategy will fail.An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of
1
, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base
— (Integer
)The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of
0
is used.
platformVersion
— (String
)The platform version to run your service on. A platform version is only specified for tasks that are hosted on Fargate. If one isn't specified, the
LATEST
platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.platformFamily
— (String
)The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.
All tasks that run as part of this service must use the same
platformFamily
value as the service (for example,LINUX
).taskDefinition
— (String
)The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
deploymentConfiguration
— (map
)Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker
— (map
)Note: The deployment circuit breaker can only be used for services using the rolling update (ECS
) deployment type.The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable
— required — (Boolean
)Determines whether to use the deployment circuit breaker logic for the service.
rollback
— required — (Boolean
)Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, themaximumPercent
parameter represents an upper limit on the number of your service's tasks that are allowed in theRUNNING
orPENDING
state during a deployment, as a percentage of thedesiredCount
(rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using theREPLICA
service scheduler and has adesiredCount
of four tasks and amaximumPercent
value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The defaultmaximumPercent
value for a service using theREPLICA
service scheduler is 200%.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.minimumHealthyPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, theminimumHealthyPercent
represents a lower limit on the number of your service's tasks that must remain in theRUNNING
state during a deployment, as a percentage of thedesiredCount
(rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has adesiredCount
of four tasks and aminimumHealthyPercent
of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.For services that do not use a load balancer, the following should be noted:
-
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
-
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a
RUNNING
state before the task is counted towards the minimum healthy percent total. -
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services that do use a load balancer, the following should be noted:
-
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
-
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
The default value for a replica service for
minimumHealthyPercent
is 100%. The defaultminimumHealthyPercent
value for a service using theDAEMON
service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.The minimum number of healthy tasks during a deployment is the
desiredCount
multiplied by theminimumHealthyPercent
/100, rounded up to the nearest integer value.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If a service is using either the blue/green (CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.-

The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
enabled

This field is not required for a "client" Amazon ECS service that's a member of a namespace only to connect to other services within the namespace. An example of this would be a frontend application that accepts incoming requests from either a load balancer that's attached to the service or by other means.
An object selects a port from the task definition, assigns a name for the Cloud Map service, and a list of aliases (endpoints) and ports for client applications to refer to this service.

Understand the following when specifying a log configuration for your containers.
-
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent.
For tasks on Fargate, the supported log drivers are
awslogs

,splunk
, andawsfirelens
. -
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
-
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the
ECS_AVAILABLE_LOGGING_DRIVERS
environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide. -
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.
logDriver

awslogs
log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.For more information about using the
awsfirelens
log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.Possible values include:"json-file"

(AWS.Response)
—
Returns:
deleteTaskDefinitions(params = {}, callback) ⇒ AWS.Request
Deletes one or more task definitions.
You must deregister a task definition revision before you delete it. For more information, see DeregisterTaskDefinition.
When you delete a task definition revision, it is immediately transitions from the
INACTIVE
toDELETE_IN_PROGRESS
. Existing tasks and services that reference aDELETE_IN_PROGRESS
task definition revision continue to run without disruption. Existing services that reference aDELETE_IN_PROGRESS
task definition revision can still scale up or down by modifying the service's desired count.You can't use a
DELETE_IN_PROGRESS
task definition revision to run new tasks or create new services. You also can't update an existing service to reference aDELETE_IN_PROGRESS
task definition revision.A task definition revision will stay in
DELETE_IN_PROGRESS
status until all the associated tasks and services have been terminated.When you delete all
INACTIVE
task definition revisions, the task definition name is not displayed in the console and not returned in the API. If a task definition revisions are in theDELETE_IN_PROGRESS
state, the task definition name is displayed in the console and returned in the API. The task definition name is retained by Amazon ECS and the revision is incremented the next time you create a task definition with that name.Service Reference:
Examples:
Calling the deleteTaskDefinitions operation
var params = { taskDefinitions: [ /* required */ 'STRING_VALUE', /* more items */ ] }; ecs.deleteTaskDefinitions(params, function(err, data) { if (err) console.log(err, err.stack); // an error occurred else console.log(data); // successful response });
Parameters:

Parameters:
-
err
(Error)
—
the error object returned from the request. Set to
null
if the request is successful. -

containerDefinitions
— (Array<map>
)A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.
name
— (String
)The name of a container. If you're linking multiple containers together in a task definition, the
name
of one container can be entered in thelinks
of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps toname
in tthe docker create-container command and the--name
option to docker run.image
— (String
)The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either
repository-url/image:tag
orrepository-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 toImage
in the docker create-container command and theIMAGE
parameter of docker run.-
When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.
-
Images in Amazon ECR repositories can be specified by either using the full
registry/repository:tag
orregistry/repository@digest
. For example,012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest
or012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE
. -
Images in official repositories on Docker Hub use a single name (for example,
ubuntu
ormongo
). -
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.
credentialsParameter
— required — (String
)The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note: When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
cpu
— (Integer
)The number of
cpu
units reserved for the container. This parameter maps toCpuShares
in the docker create-container commandand the--cpu-shares
option to docker run.This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level
cpu
value.Note: You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. The minimum valid CPU share value that the Linux kernel allows is 2, and the maximum valid CPU share value that the Linux kernel allows is 262144. However, the CPU parameter isn't required, and you can use CPU values below 2 or above 262144 in your container definitions. For CPU values below 2 (including null) or above 262144, the behavior varies based on your Amazon ECS container agent version:
-
Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.
-
Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.
-
Agent versions greater than or equal to 1.84.0: CPU values greater than 256 vCPU are passed to Docker as 256, which is equivalent to 262144 CPU shares.
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as
0
, which Windows interprets as 1% of one CPU.-
memory
— (Integer
)The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task
memory
value, if one is specified. This parameter maps toMemory
in thethe docker create-container command and the--memory
option to docker run.If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level
memory
andmemoryReservation
value,memory
must be greater thanmemoryReservation
. If you specifymemoryReservation
, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value ofmemory
is used.The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
memoryReservation
— (Integer
)The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the
memory
parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps toMemoryReservation
in the the docker create-container command and the--memory-reservation
option to docker run.If a task-level memory value is not specified, you must specify a non-zero integer for one or both of
memory
ormemoryReservation
in a container definition. If you specify both,memory
must be greater thanmemoryReservation
. If you specifymemoryReservation
, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value ofmemory
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 amemory
hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
links
— (Array<String>
)The
links
parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition isbridge
. Thename:internalName
construct is analogous toname:alias
in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.. This parameter maps toLinks
in the docker create-container command and the--link
option to docker run.Note: This parameter is not supported for Windows containers.Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
portMappings
— (Array<map>
)The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the
awsvpc
network mode, only specify thecontainerPort
. ThehostPort
can be left blank or it must be the same value as thecontainerPort
.Port mappings on Windows use the
NetNAT
gateway address rather thanlocalhost
. There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.This parameter maps to
PortBindings
in the the docker create-container command and the--publish
option to docker run. If the network mode of a task definition is set tonone
, then you can't specify port mappings. If the network mode of a task definition is set tohost
, then host ports must either be undefined or they must match the container port in the port mapping.Note: After a task reaches theRUNNING
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 thenetworkBindings
section DescribeTasks responses.containerPort
— (Integer
)The port number on the container that's bound to the user-specified or automatically assigned host port.
If you use containers in a task with the
awsvpc
orhost
network mode, specify the exposed ports usingcontainerPort
.If you use containers in a task with the
bridge
network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, seehostPort
. Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.hostPort
— (Integer
)The port number on the container instance to reserve for your container.
If you specify a
containerPortRange
, leave this field empty and the value of thehostPort
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPort
is set to the same value as thecontainerPort
. This is a static mapping strategy. -
For containers in a task with the
bridge
network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.
If you use containers in a task with the
awsvpc
orhost
network mode, thehostPort
can either be left blank or set to the same value as thecontainerPort
.If you use containers in a task with the
bridge
network mode, you can specify a non-reserved host port for your container port mapping, or you can omit thehostPort
(or set it to0
) while specifying acontainerPort
and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under
/proc/sys/net/ipv4/ip_local_port_range
. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the
remainingResources
of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.-
protocol
— (String
)The protocol used for the port mapping. Valid values are
Possible values include:tcp
andudp
. The default istcp
.protocol
is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment."tcp"
"udp"
name
— (String
)The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the
serviceConnectConfiguration
of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
appProtocol
— (String
)The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.
If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.
appProtocol
is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
Possible values include:"http"
"http2"
"grpc"
containerPortRange
— (String
)The port number range on the container that's bound to the dynamically mapped host port range.
The following rules apply when you specify a
containerPortRange
:-
You must use either the
bridge
network mode or theawsvpc
network mode. -
This parameter is available for both the EC2 and Fargate launch types.
-
This parameter is available for both the Linux and Windows operating systems.
-
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the
ecs-init
package -
You can specify a maximum of 100 port ranges per container.
-
You do not specify a
hostPortRange
. The value of thehostPortRange
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPortRange
is set to the same value as thecontainerPortRange
. This is a static mapping strategy. -
For containers in a task with the
bridge
network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
-
-
The
containerPortRange
valid values are between 1 and 65535. -
A port can only be included in one port mapping per container.
-
You cannot specify overlapping port ranges.
-
The first port in the range must be less than last port in the range.
-
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.
For more information, see Issue #11185 on the Github website.
For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.
You can call
DescribeTasks
to view thehostPortRange
which are the host ports that are bound to the container ports.-
essential
— (Boolean
)If the
essential
parameter of a container is marked astrue
, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If theessential
parameter of a container is marked asfalse
, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.
restartPolicy
— (map
)The restart policy for a container. When you set up a restart policy, Amazon ECS can restart the container without needing to replace the task.

— (Integer
)A period of time (in seconds) that the container must run for before a restart can be attempted. A container can be restarted only once every
restartAttemptPeriod
seconds. If a container isn't able to run for this time period and exits early, it will not be restarted. You can set a minimumrestartAttemptPeriod
of 60 seconds and a maximumrestartAttemptPeriod
of 1800 seconds. By default, a container must run for 300 seconds before it can be restarted.
entryPoint
— (Array<String>
)Early versions of the Amazon ECS container agent don't properly handle

option to docker run.You can specify up to ten environment files. The file must have a
.env
file extension. Each line in an environment file contains an environment variable inVARIABLE=VALUE
format. Lines beginning with#
are treated as comments and are ignored.If there are environment variables specified using the
environment
parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide.value
— required — (String
)The Amazon Resource Name (ARN) of the Amazon S3 object containing the environment variable file.

--memory-swap
option to docker run where the value would be the sum of the container memory plus themaxSwap
value.If a
maxSwap
value of0
is specified, the container will not use swap. Accepted values are0
or any positive integer. If themaxSwap

Note: If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
dependsOn
— (Array<map>
)The dependencies defined for container startup and shutdown. A container can contain multiple dependencies on other containers in a task definition. When a dependency is defined for container startup, for container shutdown it is reversed.
For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the
ecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
containerName
— required — (String
)The name of a container.
condition
— required — (String
)The dependency condition of the container. The following are the available conditions and their behavior:
-
START
- This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start. -
COMPLETE
- This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container. -
SUCCESS
- This condition is the same asCOMPLETE
, but it also requires that the container exits with azero
status. This condition can't be set on an essential container. -
HEALTHY
- This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.
"START"
"COMPLETE"
"SUCCESS"
"HEALTHY"
-
-
startTimeout
— (Integer
)Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a
COMPLETE
,SUCCESS
, orHEALTHY
status. If astartTimeout
value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to aSTOPPED
state.Note: When theECS_CONTAINER_START_TIMEOUT
container agent configuration variable is used, it's enforced independently from this start timeout value.For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
For tasks using the EC2 launch type, your container instances require at least version
1.26.0
of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version1.26.0-1
of theecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.The valid values for Fargate are 2-120 seconds.
-
stopTimeout
— (Integer
)Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks that use the EC2 launch type, if the
stopTimeout
parameter isn't specified, the value set for the Amazon ECS container agent configuration variableECS_CONTAINER_STOP_TIMEOUT
is used. If neither thestopTimeout
parameter or theECS_CONTAINER_STOP_TIMEOUT
agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of theecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.The valid values are 2-120 seconds.

hostname
— (String
)The hostname to use for your container. This parameter maps to
Hostname
in thethe docker create-container command and the--hostname
option to docker run.Note: Thehostname
parameter is not supported if you're using theawsvpc
network mode.user
— (String
)The user to use inside the container. This parameter maps to
User
in the docker create-container command and the--user
option to docker run.When running tasks using the
host
network mode, don't run containers using the root user (UID 0). We recommend using a non-root user for better security.You can specify the
user
using the following formats. If specifying a UID or GID, you must specify it as a positive integer.-

in the docker create-container command and the--log-driver
option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options).Note: Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command:
sudo docker version --format '{{.Server.APIVersion}}'
Note: The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with theECS_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.logDriver
— required — (String
)The log driver to use for the container.
For tasks on Fargate, the supported log drivers are

. For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide.Note: Tasks hosted on Fargate only support thefile
configuration file type.
credentialSpecs
— (Array<String>
)A list of ARNs in SSM or Amazon S3 to a credential spec (
CredSpec
) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of thedockerSecurityOptions
. The maximum number of ARNs is 1.There are two formats for each ARN.
- credentialspecdomainless:MyARN
-
You use
credentialspecdomainless:MyARN
to provide aCredSpec
with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.Each task that runs on any container instance can join different domains.
You can use this format without joining the container instance to a domain.
- credentialspec:MyARN
-
You use
credentialspec:MyARN
to provide aCredSpec
for a single domain.You must join the container instance to the domain before you start any tasks that use this task definition.
In both formats, replace
MyARN
with the ARN in SSM or Amazon S3.If you provide a
credentialspecdomainless:MyARN
, thecredspec
must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.
family
— (String
)The name of a family that this task definition is registered to. Up to 255 characters are allowed. Letters (both uppercase and lowercase letters), numbers, hyphens (-), and underscores (_) are allowed.

taskRoleArn
— (String
)The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.
executionRoleArn
— (String
)The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.
networkMode
— (String
)The Docker networking mode to use for the containers in the task. The valid values are
none
,bridge
,awsvpc
, andhost
. If no network mode is specified, the default isbridge
.For Amazon ECS tasks on Fargate, the
awsvpc
network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances,<default>
orawsvpc
can be used. If the network mode is set tonone
, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. Thehost
andawsvpc
network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by thebridge
mode.With the
host
andawsvpc
network modes, exposed container ports are mapped directly to the corresponding host port (for thehost
network mode) or the attached elastic network interface port (for theawsvpc
network mode), so you cannot take advantage of dynamic host port mappings.When using the
host
network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.If the network mode is
awsvpc
, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.If the network mode is
Possible values include:host
, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used."bridge"

revision
— (Integer
)The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is
1
. Each time that you register a new revision of a task definition in the same family, the revision value always increases by one. This is even if you deregistered previous revisions in this family.volumes
— (Array<map>
)The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide.
Note: Thehost

orTaskVolumeConfiguration
parameter when creating your service or standalone task.For all other types of volumes, this name is referenced in the
sourceVolume
parameter of themountPoints
object in the container definition.When a volume is using the
efsVolumeConfiguration
, the name is required.host
— (map
)This parameter is specified when you use bind mount host volumes. The contents of the
host
parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If thehost
parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.Windows containers can mount whole directories on the same drive as
$env:ProgramData
. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mountC:\my\path:C:\my\path
andD::D:\
, but notD:\my\path:C:\my\path
orD::C:\my\path
.sourcePath
— (String
)When the
host
parameter is used, specify asourcePath
to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If thehost
parameter contains asourcePath
file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If thesourcePath
value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.If you're using the Fargate launch type, the
sourcePath
parameter is not supported.
dockerVolumeConfiguration
— (map
)This parameter is specified when you use Docker volumes.
Windows containers only support the use of the
local
driver. To use bind mounts, specify thehost
parameter instead.Note: Docker volumes aren't supported by tasks run on Fargate.scope

is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base

Returns:
deregisterContainerInstance(params = {}, callback) ⇒ AWS.Request
Deregisters an Amazon ECS container instance from the specified cluster. This instance is no longer available to run tasks.
If you intend to use the container instance for some other purpose after deregistration, we recommend that you stop all of the tasks running on the container instance before deregistration. That prevents any orphaned tasks from consuming resources.
Deregistering a container instance removes the instance from a cluster, but it doesn't terminate the EC2 instance. If you are finished using the instance, be sure to terminate it in the Amazon EC2 console to stop billing.
Note: If you terminate a running container instance, Amazon ECS automatically deregisters the instance from your cluster (stopped container instances or instances with disconnected agents aren't automatically deregistered when terminated).Service Reference:
Examples:
To deregister a container instance from a cluster
/* This example deregisters a container instance from the specified cluster in your default region. If there are still tasks running on the container instance, you must either stop those tasks before deregistering, or use the force option. */ var params = { cluster: "default", containerInstance: "container_instance_UUID", force: true }; ecs.deregisterContainerInstance(params, function(err, data) { if (err) console.log(err, err.stack); // an error occurred else console.log(data); // successful response /* data = { } */ });
Calling the deregisterContainerInstance operation
var params = { containerInstance: 'STRING_VALUE', /* required */ cluster: 'STRING_VALUE', force: true || false }; ecs.deregisterContainerInstance(params, function(err, data) { if (err) console.log(err, err.stack); // an error occurred else console.log(data); // successful response });

force
option, these tasks remain running until you terminate the instance or the tasks stop through some other means, but they're orphaned (no longer monitored or accounted for by Amazon ECS). If an orphaned task on your container instance is part of an Amazon ECS service, then the service scheduler starts another copy of that task, on a different container instance if possible.Any containers in orphaned service tasks that are registered with a Classic Load Balancer or an Application Load Balancer target group are deregistered. They begin connection draining according to the settings on the load balancer or target group.

(AWS.Response)
—
Returns:
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 anINACTIVE
task definition continue to run without disruption. Existing services that reference anINACTIVE
task definition can still scale up or down by modifying the service's desired count. If you want to delete a task definition revision, you must first deregister the task definition revision.You can't use an
INACTIVE
task definition to run new tasks or create new services, and you can't update an existing service to reference anINACTIVE
task definition. However, there may be up to a 10-minute window following deregistration where these restrictions have not yet taken effect.Note: At this time,INACTIVE
task definitions remain discoverable in your account indefinitely. However, this behavior is subject to change in the future. We don't recommend that you rely onINACTIVE
task definitions persisting beyond the lifecycle of any associated tasks and services.You must deregister a task definition revision before you delete it. For more information, see DeleteTaskDefinitions.
Service Reference:
Examples:
Calling the deregisterTaskDefinition operation
var params = { taskDefinition: 'STRING_VALUE' /* required */ }; ecs.deregisterTaskDefinition(params, function(err, data) { if (err) console.log(err, err.stack); // an error occurred else console.log(data); // successful response });
Parameters:
-
params
(Object)
(defaults to: {})
—
taskDefinition
— (String
)The
family
andrevision
(family:revision
) or full Amazon Resource Name (ARN) of the task definition to deregister. You must specify arevision
.
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. Thedata
object has the following properties:taskDefinition
— (map
)The full description of the deregistered task.
taskDefinitionArn
— (String
)The full Amazon Resource Name (ARN) of the task definition.
containerDefinitions
— (Array<map>
)A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.
name
— (String
)The name of a container. If you're linking multiple containers together in a task definition, the
name
of one container can be entered in thelinks
of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps toname
in tthe docker create-container command and the--name
option to docker run.image
— (String
)The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either
repository-url/image:tag
orrepository-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 toImage
in the docker create-container command and theIMAGE
parameter of docker run.-
When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.
-
Images in Amazon ECR repositories can be specified by either using the full
registry/repository:tag
orregistry/repository@digest
. For example,012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest
or012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE
. -
Images in official repositories on Docker Hub use a single name (for example,
ubuntu
ormongo
). -
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.
credentialsParameter
— required — (String
)The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note: When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
cpu
— (Integer
)The number of
cpu
units reserved for the container. This parameter maps toCpuShares
in the docker create-container commandand the--cpu-shares
option to docker run.This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level
cpu
value.Note: You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. The minimum valid CPU share value that the Linux kernel allows is 2, and the maximum valid CPU share value that the Linux kernel allows is 262144. However, the CPU parameter isn't required, and you can use CPU values below 2 or above 262144 in your container definitions. For CPU values below 2 (including null) or above 262144, the behavior varies based on your Amazon ECS container agent version:
-
Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.
-
Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.
-
Agent versions greater than or equal to 1.84.0: CPU values greater than 256 vCPU are passed to Docker as 256, which is equivalent to 262144 CPU shares.
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as
0
, which Windows interprets as 1% of one CPU.-
memory
— (Integer
)The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task
memory
value, if one is specified. This parameter maps toMemory
in thethe docker create-container command and the--memory
option to docker run.If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level
memory
andmemoryReservation
value,memory
must be greater thanmemoryReservation
. If you specifymemoryReservation
, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value ofmemory
is used.The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
memoryReservation
— (Integer
)The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the
memory
parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps toMemoryReservation
in the the docker create-container command and the--memory-reservation
option to docker run.If a task-level memory value is not specified, you must specify a non-zero integer for one or both of
memory
ormemoryReservation
in a container definition. If you specify both,memory
must be greater thanmemoryReservation
. If you specifymemoryReservation
, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value ofmemory
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 amemory
hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
links
— (Array<String>
)The
links
parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition isbridge
. Thename:internalName
construct is analogous toname:alias
in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.. This parameter maps toLinks
in the docker create-container command and the--link
option to docker run.Note: This parameter is not supported for Windows containers.Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
portMappings
— (Array<map>
)The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the
awsvpc
network mode, only specify thecontainerPort
. ThehostPort
can be left blank or it must be the same value as thecontainerPort
.Port mappings on Windows use the
NetNAT
gateway address rather thanlocalhost
. There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.This parameter maps to
PortBindings
in the the docker create-container command and the--publish
option to docker run. If the network mode of a task definition is set tonone
, then you can't specify port mappings. If the network mode of a task definition is set tohost
, then host ports must either be undefined or they must match the container port in the port mapping.Note: After a task reaches theRUNNING
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 thenetworkBindings
section DescribeTasks responses.containerPort
— (Integer
)The port number on the container that's bound to the user-specified or automatically assigned host port.
If you use containers in a task with the
awsvpc
orhost
network mode, specify the exposed ports usingcontainerPort
.If you use containers in a task with the
bridge
network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, seehostPort
. Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.hostPort
— (Integer
)The port number on the container instance to reserve for your container.
If you specify a
containerPortRange
, leave this field empty and the value of thehostPort
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPort
is set to the same value as thecontainerPort
. This is a static mapping strategy. -
For containers in a task with the
bridge
network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.
If you use containers in a task with the
awsvpc
orhost
network mode, thehostPort
can either be left blank or set to the same value as thecontainerPort
.If you use containers in a task with the
bridge
network mode, you can specify a non-reserved host port for your container port mapping, or you can omit thehostPort
(or set it to0
) while specifying acontainerPort
and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under
/proc/sys/net/ipv4/ip_local_port_range
. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the
remainingResources
of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.-
protocol
— (String
)The protocol used for the port mapping. Valid values are
Possible values include:tcp
andudp
. The default istcp
.protocol
is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment."tcp"
"udp"
name
— (String
)The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the
serviceConnectConfiguration
of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
appProtocol
— (String
)The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.
If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.
appProtocol
is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
Possible values include:"http"
"http2"
"grpc"
containerPortRange
— (String
)The port number range on the container that's bound to the dynamically mapped host port range.
The following rules apply when you specify a
containerPortRange
:-
You must use either the
bridge
network mode or theawsvpc
network mode. -
This parameter is available for both the EC2 and Fargate launch types.
-
This parameter is available for both the Linux and Windows operating systems.
-
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the
ecs-init
package -
You can specify a maximum of 100 port ranges per container.
-
You do not specify a
hostPortRange
. The value of thehostPortRange
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPortRange
is set to the same value as thecontainerPortRange
. This is a static mapping strategy. -
For containers in a task with the
bridge
network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
-
-
The
containerPortRange
valid values are between 1 and 65535. -
A port can only be included in one port mapping per container.
-
You cannot specify overlapping port ranges.
-
The first port in the range must be less than last port in the range.
-
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.
For more information, see Issue #11185 on the Github website.
For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.
You can call
DescribeTasks
to view thehostPortRange
which are the host ports that are bound to the container ports.-
essential
— (Boolean
)If the
essential
parameter of a container is marked astrue
, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If theessential
parameter of a container is marked asfalse
, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.
restartPolicy
— (map
)The restart policy for a container. When you set up a restart policy, Amazon ECS can restart the container without needing to replace the task. For more information, see Restart individual containers in Amazon ECS tasks with container restart policies in the Amazon Elastic Container Service Developer Guide.

)Specifies whether a restart policy is enabled for the container.
ignoredExitCodes
— (Array<Integer>
)A list of exit codes that Amazon ECS will ignore and not attempt a restart on. You can specify a maximum of 50 container exit codes. By default, Amazon ECS does not ignore any exit codes.
restartAttemptPeriod
— (Integer
)A period of time (in seconds) that the container must run for before a restart can be attempted. A container can be restarted only once every
restartAttemptPeriod
seconds. If a container isn't able to run for this time period and exits early, it will not be restarted. You can set a minimumrestartAttemptPeriod
of 60 seconds and a maximumrestartAttemptPeriod
of 1800 seconds. By default, a container must run for 300 seconds before it can be restarted.
entryPoint
— (Array<String>
)Early versions of the Amazon ECS container agent don't properly handle
entryPoint
parameters. If you have problems usingentryPoint
, update your container agent or enter your commands and arguments ascommand

— (Array<map>
)A list of files containing the environment variables to pass to a container. This parameter maps to the
--env-file
option to docker run.You can specify up to ten environment files. The file must have a
.env
file extension. Each line in an environment file contains an environment variable inVARIABLE=VALUE
format. Lines beginning with#
are treated as comments and are ignored.If there are environment variables specified using the
environment
parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide.value
— required — (String
)The Amazon Resource Name (ARN) of the Amazon S3 object containing the environment variable file.

option to docker run.Note: If you are using tasks that use the Fargate launch type, thesharedMemorySize
parameter is not supported.tmpfs
— (Array<map>
)The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the
--tmpfs
option to docker run.Note: If you're using tasks that use the Fargate launch type, thetmpfs
parameter isn't supported.containerPath
— required — (String
)The absolute file path where the tmpfs volume is to be mounted.

--memory-swap
option to docker run where the value would be the sum of the container memory plus themaxSwap
value.If a
maxSwap
value of0
is specified, the container will not use swap. Accepted values are0
or any positive integer. If themaxSwap
parameter is omitted, the container will use the swap configuration for the container instance it is running on. AmaxSwap
value must be set for theswappiness
parameter to be used.Note: If you're using tasks that use the Fargate launch type, themaxSwap
parameter isn't supported. If you're using tasks on Amazon Linux 2023 theswappiness
parameter isn't supported.swappiness
— (Integer
)This allows you to tune a container's memory swappiness behavior. A

dependsOn
— (Array<map>
)The dependencies defined for container startup and shutdown. A container can contain multiple dependencies on other containers in a task definition. When a dependency is defined for container startup, for container shutdown it is reversed.
For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the
ecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
containerName
— required — (String
)The name of a container.
condition
— required — (String
)The dependency condition of the container. The following are the available conditions and their behavior:
-
START
- This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start. -
COMPLETE
- This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container. -
SUCCESS
- This condition is the same asCOMPLETE
, but it also requires that the container exits with azero
status. This condition can't be set on an essential container. -
HEALTHY
- This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.
"START"
"COMPLETE"
"SUCCESS"
"HEALTHY"
-
-
startTimeout
— (Integer
)Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a
COMPLETE
,SUCCESS
, orHEALTHY
status. If astartTimeout
value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to aSTOPPED
state.Note: When theECS_CONTAINER_START_TIMEOUT
container agent configuration variable is used, it's enforced independently from this start timeout value.For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
For tasks using the EC2 launch type, your container instances require at least version
1.26.0
of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version1.26.0-1
of theecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.The valid values for Fargate are 2-120 seconds.
-
stopTimeout
— (Integer
)Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks that use the EC2 launch type, if the
stopTimeout
parameter isn't specified, the value set for the Amazon ECS container agent configuration variableECS_CONTAINER_STOP_TIMEOUT
is used. If neither thestopTimeout
parameter or theECS_CONTAINER_STOP_TIMEOUT
agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of theecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.The valid values are 2-120 seconds.

— (map
)The log configuration specification for the container.
This parameter maps to
LogConfig
in the docker create-container command and the--log-driver
option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options).Note: Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command:
sudo docker version --format '{{.Server.APIVersion}}'
Note: The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with theECS_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.logDriver
— required — (String
)The log driver to use for the container.
For tasks on Fargate, the supported log drivers are

,gelf
,json-file
,journald
,syslog
,splunk
, andawsfirelens
.For more information about using the
awslogs
log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.For more information about using the
awsfirelens
log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.Possible values include:"json-file"
"syslog"

)The container health check command and associated configuration parameters for the container. This parameter maps to
HealthCheck
in the docker create-container command and theHEALTHCHECK
parameter of docker run.command
— required — (Array<String>
)A string array representing the command that the container runs to determine if it is healthy. The string array must start with
CMD
to run the command arguments directly, orCMD-SHELL

. For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide.Note: Tasks hosted on Fargate only support thefile
configuration file type.
credentialSpecs
— (Array<String>
)A list of ARNs in SSM or Amazon S3 to a credential spec (
CredSpec
) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of thedockerSecurityOptions
. The maximum number of ARNs is 1.There are two formats for each ARN.
- credentialspecdomainless:MyARN
-
You use
credentialspecdomainless:MyARN
to provide aCredSpec
with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.Each task that runs on any container instance can join different domains.
You can use this format without joining the container instance to a domain.
- credentialspec:MyARN
-
You use
credentialspec:MyARN
to provide aCredSpec
for a single domain.You must join the container instance to the domain before you start any tasks that use this task definition.
In both formats, replace
MyARN
with the ARN in SSM or Amazon S3.If you provide a
credentialspecdomainless:MyARN
, thecredspec
must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.
family
— (String
)The name of a family that this task definition is registered to. Up to 255 characters are allowed. Letters (both uppercase and lowercase letters), numbers, hyphens (-), and underscores (_) are allowed.
A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.
taskRoleArn
— (String
)The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.
executionRoleArn
— (String
)The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.
networkMode
— (String
)The Docker networking mode to use for the containers in the task. The valid values are
none
,bridge
,awsvpc
, andhost
. If no network mode is specified, the default isbridge
.For Amazon ECS tasks on Fargate, the
awsvpc
network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances,<default>
orawsvpc
can be used. If the network mode is set tonone
, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. Thehost
andawsvpc
network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by thebridge
mode.With the
host
andawsvpc
network modes, exposed container ports are mapped directly to the corresponding host port (for thehost
network mode) or the attached elastic network interface port (for theawsvpc
network mode), so you cannot take advantage of dynamic host port mappings.When using the
host
network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.If the network mode is
awsvpc
, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.If the network mode is
Possible values include:host
, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used."bridge"
"host"
"awsvpc"
"none"
revision
— (Integer
)The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is
1
. Each time that you register a new revision of a task definition in the same family, the revision value always increases by one. This is even if you deregistered previous revisions in this family.volumes
— (Array<map>
)The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide.
Note: Thehost
andsourcePath
parameters aren't supported for tasks run on Fargate.name
— (String
)The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.
When using a volume configured at launch, the
name
is required and must also be specified as the volume name in theServiceVolumeConfiguration
orTaskVolumeConfiguration
parameter when creating your service or standalone task.For all other types of volumes, this name is referenced in the
sourceVolume
parameter of themountPoints
object in the container definition.When a volume is using the
efsVolumeConfiguration
, the name is required.host
— (map
)This parameter is specified when you use bind mount host volumes. The contents of the
host
parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If thehost
parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.Windows containers can mount whole directories on the same drive as
$env:ProgramData
. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mountC:\my\path:C:\my\path
andD::D:\
, but notD:\my\path:C:\my\path
orD::C:\my\path
.sourcePath
— (String
)When the
host
parameter is used, specify asourcePath
to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If thehost
parameter contains asourcePath
file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If thesourcePath
value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.If you're using the Fargate launch type, the
sourcePath
parameter is not supported.
dockerVolumeConfiguration
— (map
)This parameter is specified when you use Docker volumes.
Windows containers only support the use of the
local
driver. To use bind mounts, specify thehost
parameter instead.Note: Docker volumes aren't supported by tasks run on Fargate.scope
— (String

-
Maximum key length - 128 Unicode characters in UTF-8
-
Maximum value length - 256 Unicode characters in UTF-8
-
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
-
Tag keys and values are case-sensitive.

enabled
anddisabled
.If you set
name
tocontainerInsights

)The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The
weight
value is taken into consideration after thebase
value, if defined, is satisfied.If no
weight
value is specified, the default value of0
is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of0
can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService
actions using the capacity provider strategy will fail.An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of
1
, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base

)The port value used if your service discovery service specified an SRV record. This field might be used if both the
awsvpc
network mode and SRV records are used.containerName
— (String
)The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the
bridge
orhost
network mode, you must specify acontainerName
andcontainerPort
combination from the task definition. If the task definition that your service task specifies uses theawsvpc
network mode and a type SRV DNS record is used, you must specify either acontainerName
andcontainerPort
combination or aport
value. However, you can't specify both.containerPort
— (Integer
)The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the
bridge
orhost
network mode, you must specify acontainerName
andcontainerPort
combination from the task definition. If the task definition your service task specifies uses theawsvpc
network mode and a type SRV DNS record is used, you must specify either acontainerName
andcontainerPort
combination or aport
value. However, you can't specify both.
status
— (String
)The status of the service. The valid values are
ACTIVE
,DRAINING
, orINACTIVE
.desiredCount
— (Integer
)The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.

— (Integer
)The number of tasks in the cluster that are in the
RUNNING
state.pendingCount
— (Integer
)The number of tasks in the cluster that are in the
PENDING
state.launchType
— (String

Possible values include:"EC2"
"FARGATE"
"EXTERNAL"
capacityProviderStrategy
— (Array<map>
)The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
capacityProvider
— required — (String
)The short name of the capacity provider.
weight
— (Integer
)The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The
weight
value is taken into consideration after thebase
value, if defined, is satisfied.If no
weight
value is specified, the default value of0
is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of0
can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService
actions using the capacity provider strategy will fail.An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of
1
, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base
— (Integer
)The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of
0
is used.
platformVersion
— (String
)The platform version to run your service on. A platform version is only specified for tasks that are hosted on Fargate. If one isn't specified, the
LATEST
platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.platformFamily
— (String
)The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.
All tasks that run as part of this service must use the same
platformFamily
value as the service (for example,LINUX
).taskDefinition
— (String
)The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
deploymentConfiguration
— (map
)Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker
— (map
)Note: The deployment circuit breaker can only be used for services using the rolling update (ECS
) deployment type.The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable
— required — (Boolean
)Determines whether to use the deployment circuit breaker logic for the service.
rollback
— required — (Boolean
)Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, themaximumPercent
parameter represents an upper limit on the number of your service's tasks that are allowed in theRUNNING
orPENDING
state during a deployment, as a percentage of thedesiredCount
(rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using theREPLICA
service scheduler and has adesiredCount
of four tasks and amaximumPercent
value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The defaultmaximumPercent
value for a service using theREPLICA
service scheduler is 200%.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.minimumHealthyPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, theminimumHealthyPercent
represents a lower limit on the number of your service's tasks that must remain in theRUNNING
state during a deployment, as a percentage of thedesiredCount
(rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has adesiredCount
of four tasks and aminimumHealthyPercent
of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.For services that do not use a load balancer, the following should be noted:
-
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
-
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a
RUNNING
state before the task is counted towards the minimum healthy percent total. -
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services that do use a load balancer, the following should be noted:
-
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
-
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
The default value for a replica service for
minimumHealthyPercent
is 100%. The defaultminimumHealthyPercent
value for a service using theDAEMON
service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.The minimum number of healthy tasks during a deployment is the
desiredCount
multiplied by theminimumHealthyPercent
/100, rounded up to the nearest integer value.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If a service is using either the blue/green (CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.-

LogConfig
in the docker create-container command and the--log-driver
option to docker run.By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition.
Understand the following when specifying a log configuration for your containers.
-
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent.
For tasks on Fargate, the supported log drivers are
awslogs
,splunk
, andawsfirelens
.For tasks hosted on Amazon EC2 instances, the supported log drivers are
awslogs
,fluentd
,gelf
,json-file
,journald
,syslog
,splunk
, andawsfirelens
. -
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
-
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the
ECS_AVAILABLE_LOGGING_DRIVERS
environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide. -
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.
logDriver
— required — (String
)The log driver to use for the container.
For tasks on Fargate, the supported log drivers are
awslogs
,splunk
, andawsfirelens
.For tasks hosted on Amazon EC2 instances, the supported log drivers are
awslogs
,fluentd
,gelf
,json-file
,journald
,syslog
,splunk
, andawsfirelens
.For more information about using the
awslogs
log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.For more information about using the
awsfirelens
log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.Possible values include:"json-file"
"syslog"
"journald"
"gelf"

"ECS"
"CODE_DEPLOY"
"EXTERNAL"
tags
— (Array<map>
)The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value. You define bot the key and value.
The following basic restrictions apply to tags:

to find information about a specific task definition, or you can simply specify the family to find the latestACTIVE
revision in that family.Note: You can only describeINACTIVE
task definitions while an active task or service references them.Service Reference:
Examples:
To describe a task definition
/* This example provides a description of the specified task definition. */ var params = { taskDefinition: "hello_world:8" }; ecs.describeTaskDefinition(params, function(err, data) { if (err) console.log(err, err.stack); // an error occurred else console.log(data); // successful response /* data = { taskDefinition: { containerDefinitions: [ { name: "wordpress", cpu: 10, environment: [ ], essential: true, image: "wordpress", links: [ "mysql" ], memory: 500, mountPoints: [ ], portMappings: [ { containerPort: 80, hostPort: 80 } ], volumesFrom: [ ] }, { name: "mysql", cpu: 10, environment: [ { name: "MYSQL_ROOT_PASSWORD", value: "password" } ], essential: true, image: "mysql", memory: 500, mountPoints: [ ], portMappings: [ ], volumesFrom: [ ] } ], family: "hello_world", revision: 8, taskDefinitionArn: "arn:aws:ecs:us-east-1:<aws_account_id>:task-definition/hello_world:8", volumes: [ ] } } */ });

)Determines whether to see the resource tags for the task definition. If
TAGS
is specified, the tags are included in the response. If this field is omitted, tags aren't included in the response.
Callback (callback):
-
function(err, data) { ... }
Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.
Context (this):
-
(AWS.Response)
—
the response object containing error, data properties, and the original request object.
Parameters:
-
err
(Error)
—
the error object returned from the request. Set to
null
if the request is successful. -
data
(Object)
—
the de-serialized data returned from the request. Set to
null
if a request error occurs. Thedata
object has the following properties:taskDefinition
— (map

taskDefinitionArn
— (String
)The full Amazon Resource Name (ARN) of the task definition.
containerDefinitions
— (Array<map>
)A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.
name
— (String
)The name of a container. If you're linking multiple containers together in a task definition, the
name
of one container can be entered in thelinks
of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps toname
in tthe docker create-container command and the--name
option to docker run.image
— (String
)The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either
repository-url/image:tag
orrepository-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 toImage
in the docker create-container command and theIMAGE
parameter of docker run.-
When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.
-
Images in Amazon ECR repositories can be specified by either using the full
registry/repository:tag
orregistry/repository@digest
. For example,012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest
or012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE
. -
Images in official repositories on Docker Hub use a single name (for example,
ubuntu
ormongo
). -
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.
credentialsParameter
— required — (String
)The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note: When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
cpu
— (Integer
)The number of
cpu
units reserved for the container. This parameter maps toCpuShares
in the docker create-container commandand the--cpu-shares
option to docker run.This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level
cpu
value.Note: You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. The minimum valid CPU share value that the Linux kernel allows is 2, and the maximum valid CPU share value that the Linux kernel allows is 262144. However, the CPU parameter isn't required, and you can use CPU values below 2 or above 262144 in your container definitions. For CPU values below 2 (including null) or above 262144, the behavior varies based on your Amazon ECS container agent version:
-
Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.
-
Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.
-
Agent versions greater than or equal to 1.84.0: CPU values greater than 256 vCPU are passed to Docker as 256, which is equivalent to 262144 CPU shares.
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as
0
, which Windows interprets as 1% of one CPU.-
memory
— (Integer
)The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task
memory
value, if one is specified. This parameter maps toMemory
in thethe docker create-container command and the--memory
option to docker run.If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level
memory
andmemoryReservation
value,memory
must be greater thanmemoryReservation
. If you specifymemoryReservation
, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value ofmemory
is used.The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
memoryReservation
— (Integer
)The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the
memory
parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps toMemoryReservation
in the the docker create-container command and the--memory-reservation
option to docker run.If a task-level memory value is not specified, you must specify a non-zero integer for one or both of
memory
ormemoryReservation
in a container definition. If you specify both,memory
must be greater thanmemoryReservation
. If you specifymemoryReservation
, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value ofmemory
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 amemory
hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
links
— (Array<String>
)The
links
parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition isbridge
. Thename:internalName
construct is analogous toname:alias
in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.. This parameter maps toLinks
in the docker create-container command and the--link
option to docker run.Note: This parameter is not supported for Windows containers.Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
portMappings
— (Array<map>
)The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the
awsvpc
network mode, only specify thecontainerPort
. ThehostPort
can be left blank or it must be the same value as thecontainerPort
.Port mappings on Windows use the
NetNAT
gateway address rather thanlocalhost
. There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.This parameter maps to
PortBindings
in the the docker create-container command and the--publish
option to docker run. If the network mode of a task definition is set tonone
, then you can't specify port mappings. If the network mode of a task definition is set tohost
, then host ports must either be undefined or they must match the container port in the port mapping.Note: After a task reaches theRUNNING
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 thenetworkBindings
section DescribeTasks responses.containerPort
— (Integer
)The port number on the container that's bound to the user-specified or automatically assigned host port.
If you use containers in a task with the
awsvpc
orhost
network mode, specify the exposed ports usingcontainerPort
.If you use containers in a task with the
bridge
network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, seehostPort
. Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.hostPort
— (Integer
)The port number on the container instance to reserve for your container.
If you specify a
containerPortRange
, leave this field empty and the value of thehostPort
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPort
is set to the same value as thecontainerPort
. This is a static mapping strategy. -
For containers in a task with the
bridge
network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.
If you use containers in a task with the
awsvpc
orhost
network mode, thehostPort
can either be left blank or set to the same value as thecontainerPort
.If you use containers in a task with the
bridge
network mode, you can specify a non-reserved host port for your container port mapping, or you can omit thehostPort
(or set it to0
) while specifying acontainerPort
and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under
/proc/sys/net/ipv4/ip_local_port_range
. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the
remainingResources
of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.-
protocol
— (String
)The protocol used for the port mapping. Valid values are
Possible values include:tcp
andudp
. The default istcp
.protocol
is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment."tcp"
"udp"
name
— (String
)The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the
serviceConnectConfiguration
of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
appProtocol
— (String
)The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.
If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.
appProtocol
is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
Possible values include:"http"
"http2"
"grpc"
containerPortRange
— (String
)The port number range on the container that's bound to the dynamically mapped host port range.

network mode. -
This parameter is available for both the EC2 and Fargate launch types.
-
This parameter is available for both the Linux and Windows operating systems.
-
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the
ecs-init
package -
You can specify a maximum of 100 port ranges per container.
-
You do not specify a
hostPortRange
. The value of thehostPortRange
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPortRange
is set to the same value as thecontainerPortRange
. This is a static mapping strategy. -
For containers in a task with the
bridge
network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
-
-
The
containerPortRange
valid values are between 1 and 65535. -
A port can only be included in one port mapping per container.
-
You cannot specify overlapping port ranges.
-
The first port in the range must be less than last port in the range.
-
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.
For more information, see Issue #11185 on the Github website.
For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.
You can call
DescribeTasks
to view thehostPortRange
which are the host ports that are bound to the container ports.-
essential
— (Boolean
)If the
essential
parameter of a container is marked astrue
, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If theessential
parameter of a container is marked asfalse
, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.
restartPolicy

)A period of time (in seconds) that the container must run for before a restart can be attempted. A container can be restarted only once every
restartAttemptPeriod
seconds. If a container isn't able to run for this time period and exits early, it will not be restarted. You can set a minimumrestartAttemptPeriod
of 60 seconds and a maximumrestartAttemptPeriod
of 1800 seconds. By default, a container must run for 300 seconds before it can be restarted.

format. Lines beginning with#
are treated as comments and are ignored.If there are environment variables specified using the
environment
parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide.value

For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the
ecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
containerName

)The name of a container.
condition
— required — (String
)The dependency condition of the container. The following are the available conditions and their behavior:
-
START
- This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start. -
COMPLETE
- This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container. -
SUCCESS
- This condition is the same asCOMPLETE
, but it also requires that the container exits with azero
status. This condition can't be set on an essential container. -
HEALTHY
- This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.
"START"
"COMPLETE"
"SUCCESS"
"HEALTHY"
-
-
startTimeout
— (Integer
)Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a
COMPLETE
,SUCCESS
, orHEALTHY
status. If astartTimeout
value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to aSTOPPED
state.Note: When theECS_CONTAINER_START_TIMEOUT
container agent configuration variable is used, it's enforced independently from this start timeout value.For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
For tasks using the EC2 launch type, your container instances require at least version
1.26.0
of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version1.26.0-1
of theecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.The valid values for Fargate are 2-120 seconds.
-
stopTimeout
— (Integer
)Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks that use the EC2 launch type, if the
stopTimeout
parameter isn't specified, the value set for the Amazon ECS container agent configuration variableECS_CONTAINER_STOP_TIMEOUT
is used. If neither thestopTimeout
parameter or theECS_CONTAINER_STOP_TIMEOUT
agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of theecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.The valid values are 2-120 seconds.

logConfiguration
— (map
)The log configuration specification for the container.
This parameter maps to
LogConfig
in the docker create-container command and the--log-driver
option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options).Note: Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command:
sudo docker version --format '{{.Server.APIVersion}}'
Note: The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with theECS_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.logDriver
— required — (String
)The log driver to use for the container.
For tasks on Fargate, the supported log drivers are
awslogs
,splunk

.For tasks hosted on Amazon EC2 instances, the supported log drivers are
awslogs
,fluentd
,gelf
,json-file
,journald
,syslog
,splunk
, andawsfirelens
.For more information about using the
awslogs
log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.For more information about using the
awsfirelens
log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.Possible values include:"json-file"

, then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
systemControls
— (Array<map>
)A list of namespaced kernel parameters to set in the container. This parameter maps to
Sysctls
in tthe docker create-container command and the--sysctl

"options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"}
. For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide.Note: Tasks hosted on Fargate only support thefile
configuration file type.
credentialSpecs
— (Array<String>
)A list of ARNs in SSM or Amazon S3 to a credential spec (
CredSpec
) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of thedockerSecurityOptions
. The maximum number of ARNs is 1.There are two formats for each ARN.
- credentialspecdomainless:MyARN
-
You use
credentialspecdomainless:MyARN
to provide aCredSpec
with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.Each task that runs on any container instance can join different domains.
You can use this format without joining the container instance to a domain.
- credentialspec:MyARN
-
You use
credentialspec:MyARN
to provide aCredSpec
for a single domain.You must join the container instance to the domain before you start any tasks that use this task definition.
In both formats, replace
MyARN
with the ARN in SSM or Amazon S3.If you provide a
credentialspecdomainless:MyARN
, thecredspec
must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.
family
— (String
)The name of a family that this task definition is registered to. Up to 255 characters are allowed. Letters (both uppercase and lowercase letters), numbers, hyphens (-), and underscores (_) are allowed.
A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.
taskRoleArn
— (String
)The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.
executionRoleArn
— (String
)The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.
networkMode
— (String
)The Docker networking mode to use for the containers in the task. The valid values are
none
,bridge
,awsvpc
, andhost
. If no network mode is specified, the default isbridge
.For Amazon ECS tasks on Fargate, the
awsvpc
network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances,<default>
orawsvpc
can be used. If the network mode is set tonone
, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. Thehost
andawsvpc
network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by thebridge
mode.With the
host
andawsvpc
network modes, exposed container ports are mapped directly to the corresponding host port (for thehost
network mode) or the attached elastic network interface port (for theawsvpc
network mode), so you cannot take advantage of dynamic host port mappings.When using the
host
network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.If the network mode is
awsvpc
, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.If the network mode is
Possible values include:host
, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used."bridge"
"host"
"awsvpc"

revision
— (Integer
)The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is
1
. Each time that you register a new revision of a task definition in the same family, the revision value always increases by one. This is even if you deregistered previous revisions in this family.volumes
— (Array<map>
)The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide.
Note: Thehost

orTaskVolumeConfiguration
parameter when creating your service or standalone task.For all other types of volumes, this name is referenced in the
sourceVolume
parameter of themountPoints
object in the container definition.When a volume is using the
efsVolumeConfiguration
, the name is required.host
— (map
)This parameter is specified when you use bind mount host volumes. The contents of the
host
parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If thehost
parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.Windows containers can mount whole directories on the same drive as
$env:ProgramData
. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mountC:\my\path:C:\my\path
andD::D:\
, but notD:\my\path:C:\my\path
orD::C:\my\path
.sourcePath
— (String
)When the
host
parameter is used, specify asourcePath
to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If thehost
parameter contains asourcePath
file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If thesourcePath
value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.If you're using the Fargate launch type, the
sourcePath
parameter is not supported.
dockerVolumeConfiguration
— (map
)This parameter is specified when you use Docker volumes.
Windows containers only support the use of the
local

network mode, thehostPortRange
is set to the same value as thecontainerPortRange
. This is a static mapping strategy. -
For containers in a task with the

weight
— (Integer
)The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The
weight
value is taken into consideration after thebase
value, if defined, is satisfied.If no
weight
value is specified, the default value of0
is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of0
can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService
actions using the capacity provider strategy will fail.An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of
1
, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base

Returns:
listAttributes(params = {}, callback) ⇒ AWS.Request
Lists the attributes for Amazon ECS resources within a specified target type and cluster. When you specify a target type and cluster,
ListAttributes
returns a list of attribute objects, one for each attribute on each resource. You can filter the list of results to a single attribute name to only return results that have that name. You can also filter the results by attribute name and value. You can do this, for example, to see which container instances in a cluster are running a Linux AMI (ecs.os-type=linux
).Service Reference:
Examples:
Calling the listAttributes operation
var params = { targetType: container-instance, /* required */ attributeName: 'STRING_VALUE', attributeValue: 'STRING_VALUE', cluster: 'STRING_VALUE', maxResults: 'NUMBER_VALUE', nextToken: 'STRING_VALUE' }; ecs.listAttributes(params, function(err, data) { if (err) console.log(err, err.stack); // an error occurred else console.log(data); // successful response });

To list the tasks on a particular container instance
/* This example lists the tasks of a specified container instance. Specifying a ``containerInstance`` value limits the results to tasks that belong to that container instance. */ var params = { cluster: "default", containerInstance: "f6bbb147-5370-4ace-8c73-c7181ded911f" }; ecs.listTasks(params, function(err, data) { if (err) console.log(err, err.stack); // an error occurred else console.log(data); // successful response /* data = { taskArns: [ "arn:aws:ecs:us-east-1:012345678910:task/default/0cc43cdb-3bee-4407-9c26-c0e6ea5bee84" ] } */ });
Calling the listTasks operation

ListTasks
results. 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 use when filtering the
ListTasks
results. Specifying acontainerInstance
limits the results to tasks that belong to that container instance.family
— (String
)The name of the task definition family to use when filtering the
ListTasks
results. Specifying afamily
limits the results to tasks that belong to that family.nextToken
— (String
)The
nextToken
value returned from aListTasks
request indicating that more results are available to fulfill the request and further calls will be needed. IfmaxResults
was provided, it's possible the number of results to be fewer thanmaxResults
.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 that
ListTasks
returned in paginated output. When this parameter is used,ListTasks
only returnsmaxResults
results in a single page along with anextToken
response element. The remaining results of the initial request can be seen by sending anotherListTasks
request with the returnednextToken
value. This value can be between 1 and 100. If this parameter isn't used, thenListTasks
returns up to 100 results and anextToken
value if applicable.startedBy
— (String
)The
startedBy
value to filter the task results with. Specifying astartedBy
value limits the results to tasks that were started with that value.When you specify
startedBy
as the filter, it must be the only filter that you use.serviceName
— (String
)The name of the service to use when filtering the
ListTasks
results. Specifying aserviceName

, which shows tasks that Amazon ECS has set the desired status toRUNNING
.Note: Although you can filter results based on a desired status ofPossible values include:PENDING
, this doesn't return any results. Amazon ECS never sets the desired status of a task to that value (only a task'slastStatus
may have a value ofPENDING
)."RUNNING"

name
— (String
)The Amazon ECS account setting name to modify.
The following are the valid values for the account setting name.
-
serviceLongArnFormat
- When modified, the Amazon Resource Name (ARN) and resource ID format of the resource type for a specified user, role, or the root user for an account is affected. The opt-in and opt-out account setting must be set for each Amazon ECS resource separately. The ARN and resource ID format of a resource is defined by the opt-in status of the user or role that created the resource. You must turn on this setting to use Amazon ECS features such as resource tagging. -
taskLongArnFormat
- When modified, the Amazon Resource Name (ARN) and resource ID format of the resource type for a specified user, role, or the root user for an account is affected. The opt-in and opt-out account setting must be set for each Amazon ECS resource separately. The ARN and resource ID format of a resource is defined by the opt-in status of the user or role that created the resource. You must turn on this setting to use Amazon ECS features such as resource tagging. -
containerInstanceLongArnFormat
- When modified, the Amazon Resource Name (ARN) and resource ID format of the resource type for a specified user, role, or the root user for an account is affected. The opt-in and opt-out account setting must be set for each Amazon ECS resource separately. The ARN and resource ID format of a resource is defined by the opt-in status of the user or role that created the resource. You must turn on this setting to use Amazon ECS features such as resource tagging. -
awsvpcTrunking
- When modified, the elastic network interface (ENI) limit for any new container instances that support the feature is changed. IfawsvpcTrunking
is turned on, any new container instances that support the feature are launched have the increased ENI limits available to them. For more information, see Elastic Network Interface Trunking in the Amazon Elastic Container Service Developer Guide. -
containerInsights
- When modified, the default setting indicating whether Amazon Web Services CloudWatch Container Insights is turned on for your clusters is changed. IfcontainerInsights
is turned on, any new clusters that are created will have Container Insights turned on unless you disable it during cluster creation. For more information, see CloudWatch Container Insights in the Amazon Elastic Container Service Developer Guide. -
dualStackIPv6
- When turned on, when using a VPC in dual stack mode, your tasks using theawsvpc
network mode can have an IPv6 address assigned. For more information on using IPv6 with tasks launched on Amazon EC2 instances, see Using a VPC in dual-stack mode. For more information on using IPv6 with tasks launched on Fargate, see Using a VPC in dual-stack mode. -
fargateFIPSMode
- If you specifyfargateFIPSMode
, Fargate FIPS 140 compliance is affected. -
fargateTaskRetirementWaitPeriod
- When Amazon Web Services determines that a security or infrastructure update is needed for an Amazon ECS task hosted on Fargate, the tasks need to be stopped and new tasks launched to replace them. UsefargateTaskRetirementWaitPeriod
to configure the wait time to retire a Fargate task. For information about the Fargate tasks maintenance, see Amazon Web Services Fargate task maintenance in the Amazon ECS Developer Guide. -
tagResourceAuthorization
- Amazon ECS is introducing tagging authorization for resource creation. Users must have permissions for actions that create the resource, such asecsCreateCluster
. If tags are specified when you create a resource, Amazon Web Services performs additional authorization to verify if users or roles have permissions to create tags. Therefore, you must grant explicit permissions to use theecs:TagResource
action. For more information, see Grant permission to tag resources on creation in the Amazon ECS Developer Guide. -
guardDutyActivate
- TheguardDutyActivate
parameter is read-only in Amazon ECS and indicates whether Amazon ECS Runtime Monitoring is enabled or disabled by your security administrator in your Amazon ECS account. Amazon GuardDuty controls this account setting on your behalf. For more information, see Protecting Amazon ECS workloads with Amazon ECS Runtime Monitoring.

putClusterCapacityProviders(params = {}, callback) ⇒ AWS.Request
Modifies the available capacity providers and the default capacity provider strategy for a cluster.
You must specify both the available capacity providers and a default capacity provider strategy for the cluster. If the specified cluster has existing capacity providers associated with it, you must specify all existing capacity providers in addition to any new ones you want to add. Any existing capacity providers that are associated with a cluster that are omitted from a PutClusterCapacityProviders API call will be disassociated with the cluster. You can only disassociate an existing capacity provider from a cluster if it's not being used by any existing tasks.
When creating a service or running a task on a cluster, if no capacity provider or launch type is specified, then the cluster's default capacity provider strategy is used. We recommend that you define a default capacity provider strategy for your cluster. However, you must specify an empty array (
[]
) to bypass defining a default strategy.Service Reference:
Examples:
Calling the putClusterCapacityProviders operation
var params = { capacityProviders: [ /* required */ 'STRING_VALUE', /* more items */ ], cluster: 'STRING_VALUE', /* required */ defaultCapacityProviderStrategy: [ /* required */ { capacityProvider: 'STRING_VALUE', /* required */ base: 'NUMBER_VALUE', weight: 'NUMBER_VALUE' }, /* more items */ ] }; ecs.putClusterCapacityProviders(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 to modify the capacity provider settings for. If you don't specify a cluster, the default cluster is assumed.
capacityProviders
— (Array<String>
)The name of one or more capacity providers to associate with the cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the
FARGATE
orFARGATE_SPOT
capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.defaultCapacityProviderStrategy
— (Array<map>
)The capacity provider strategy to use by default for the cluster.
When creating a service or running a task on a cluster, if no capacity provider or launch type is specified then the default capacity provider strategy for the cluster is used.
A capacity provider strategy consists of one or more capacity providers along with the
base
andweight
to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster. Only capacity providers with anACTIVE
orUPDATING
status can be used.If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the
FARGATE
orFARGATE_SPOT
capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.capacityProvider
— required — (String
)The short name of the capacity provider.
weight
— (Integer
)The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The
weight
value is taken into consideration after thebase
value, if defined, is satisfied.If no
weight
value is specified, the default value of0
is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of0
can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService

Parameters:
-
params
(Object)
(defaults to: {})
—
family
— (String
)You must specify a
family
for a task definition. You can use it track multiple versions of the same task definition. Thefamily
is used as a name for your task definition. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens 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 grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.
networkMode
— (String
)The Docker networking mode to use for the containers in the task. The valid values are
none
,bridge
,awsvpc
, andhost
. If no network mode is specified, the default isbridge
.For Amazon ECS tasks on Fargate, the
awsvpc
network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances,<default>
orawsvpc
can be used. If the network mode is set tonone
, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. Thehost
andawsvpc
network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by thebridge
mode.With the
host
andawsvpc
network modes, exposed container ports are mapped directly to the corresponding host port (for thehost
network mode) or the attached elastic network interface port (for theawsvpc
network mode), so you cannot take advantage of dynamic host port mappings.When using the
host
network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.If the network mode is
awsvpc
, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.If the network mode is
Possible values include:host
, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used."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're linking multiple containers together in a task definition, the
name
of one container can be entered in thelinks
of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps toname
in tthe docker create-container command and the--name
option to docker run.image
— (String
)The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either
repository-url/image:tag
orrepository-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 toImage
in the docker create-container command and theIMAGE
parameter of docker run.-
When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.
-
Images in Amazon ECR repositories can be specified by either using the full
registry/repository:tag
orregistry/repository@digest
. For example,012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest
or012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE
. -
Images in official repositories on Docker Hub use a single name (for example,
ubuntu
ormongo
). -
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.
credentialsParameter
— required — (String
)The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note: When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
cpu
— (Integer
)The number of
cpu
units reserved for the container. This parameter maps toCpuShares
in the docker create-container commandand the--cpu-shares
option to docker run.This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level
cpu
value.Note: You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. The minimum valid CPU share value that the Linux kernel allows is 2, and the maximum valid CPU share value that the Linux kernel allows is 262144. However, the CPU parameter isn't required, and you can use CPU values below 2 or above 262144 in your container definitions. For CPU values below 2 (including null) or above 262144, the behavior varies based on your Amazon ECS container agent version:
-
Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.
-
Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.
-
Agent versions greater than or equal to 1.84.0: CPU values greater than 256 vCPU are passed to Docker as 256, which is equivalent to 262144 CPU shares.
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as
0
, which Windows interprets as 1% of one CPU.-
memory
— (Integer
)The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task
memory
value, if one is specified. This parameter maps toMemory
in thethe docker create-container command and the--memory
option to docker run.If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level
memory
andmemoryReservation
value,memory
must be greater thanmemoryReservation
. If you specifymemoryReservation
, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value ofmemory
is used.The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
memoryReservation
— (Integer
)The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the
memory
parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps toMemoryReservation
in the the docker create-container command and the--memory-reservation
option to docker run.If a task-level memory value is not specified, you must specify a non-zero integer for one or both of
memory
ormemoryReservation
in a container definition. If you specify both,memory
must be greater thanmemoryReservation
. If you specifymemoryReservation
, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value ofmemory
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 amemory
hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
links
— (Array<String>
)The
links
parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition isbridge
. Thename:internalName
construct is analogous toname:alias
in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.. This parameter maps toLinks
in the docker create-container command and the--link
option to docker run.Note: This parameter is not supported for Windows containers.Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
portMappings
— (Array<map>
)The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the
awsvpc
network mode, only specify thecontainerPort
. ThehostPort
can be left blank or it must be the same value as thecontainerPort
.Port mappings on Windows use the
NetNAT
gateway address rather thanlocalhost
. There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.This parameter maps to
PortBindings
in the the docker create-container command and the--publish
option to docker run. If the network mode of a task definition is set tonone
, then you can't specify port mappings. If the network mode of a task definition is set tohost
, then host ports must either be undefined or they must match the container port in the port mapping.Note: After a task reaches theRUNNING
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 thenetworkBindings
section DescribeTasks responses.containerPort
— (Integer
)The port number on the container that's bound to the user-specified or automatically assigned host port.
If you use containers in a task with the
awsvpc
orhost
network mode, specify the exposed ports usingcontainerPort
.If you use containers in a task with the
bridge
network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, seehostPort
. Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.hostPort
— (Integer
)The port number on the container instance to reserve for your container.
If you specify a
containerPortRange
, leave this field empty and the value of thehostPort
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPort
is set to the same value as thecontainerPort
. This is a static mapping strategy. -
For containers in a task with the
bridge
network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.
If you use containers in a task with the
awsvpc
orhost
network mode, thehostPort
can either be left blank or set to the same value as thecontainerPort
.If you use containers in a task with the
bridge
network mode, you can specify a non-reserved host port for your container port mapping, or you can omit thehostPort
(or set it to0
) while specifying acontainerPort
and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under
/proc/sys/net/ipv4/ip_local_port_range
. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the
remainingResources
of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.-
protocol
— (String
)The protocol used for the port mapping. Valid values are
Possible values include:tcp
andudp
. The default istcp
.protocol
is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment."tcp"
"udp"
name
— (String
)The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the
serviceConnectConfiguration
of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
appProtocol
— (String
)The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.
If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.
appProtocol
is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
Possible values include:"http"
"http2"
"grpc"
containerPortRange
— (String
)The port number range on the container that's bound to the dynamically mapped host port range.
The following rules apply when you specify a
containerPortRange
:-
You must use either the
bridge
network mode or theawsvpc
network mode. -
This parameter is available for both the EC2 and Fargate launch types.
-
This parameter is available for both the Linux and Windows operating systems.
-
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the
ecs-init
package -
You can specify a maximum of 100 port ranges per container.
-
You do not specify a
hostPortRange
. The value of thehostPortRange
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPortRange
is set to the same value as thecontainerPortRange
. This is a static mapping strategy. -
For containers in a task with the
bridge
network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
-
-
The
containerPortRange
valid values are between 1 and 65535. -
A port can only be included in one port mapping per container.
-
You cannot specify overlapping port ranges.
-
The first port in the range must be less than last port in the range.
-
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.
For more information, see Issue #11185 on the Github website.
For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.
You can call
DescribeTasks
to view thehostPortRange
which are the host ports that are bound to the container ports.-
essential
— (Boolean
)If the
essential
parameter of a container is marked astrue
, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If theessential
parameter of a container is marked asfalse
, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.
restartPolicy
— (map
)The restart policy for a container. When you set up a restart policy, Amazon ECS can restart the container without needing to replace the task. For more information, see Restart individual containers in Amazon ECS tasks with container restart policies in the Amazon Elastic Container Service Developer Guide.
enabled
— required — (Boolean
)Specifies whether a restart policy is enabled for the container.
ignoredExitCodes
— (Array<Integer>
)A list of exit codes that Amazon ECS will ignore and not attempt a restart on. You can specify a maximum of 50 container exit codes. By default, Amazon ECS does not ignore any exit codes.
restartAttemptPeriod
— (Integer
)A period of time (in seconds) that the container must run for before a restart can be attempted. A container can be restarted only once every
restartAttemptPeriod
seconds. If a container isn't able to run for this time period and exits early, it will not be restarted. You can set a minimumrestartAttemptPeriod
of 60 seconds and a maximumrestartAttemptPeriod
of 1800 seconds. By default, a container must run for 300 seconds before it can be restarted.
entryPoint
— (Array<String>
)Early versions of the Amazon ECS container agent don't properly handle
entryPoint
parameters. If you have problems usingentryPoint
, update your container agent or enter your commands and arguments ascommand
array items instead.The entry point that's passed to the container. This parameter maps to
Entrypoint
in tthe docker create-container command and the--entrypoint
option to docker run.command
— (Array<String>
)The command that's passed to the container. This parameter maps to
Cmd
in the docker create-container command and theCOMMAND
parameter to docker run. If there are multiple arguments, each argument is a separated string in the array.environment
— (Array<map>
)The environment variables to pass to a container. This parameter maps to
Env
in the docker create-container command and the--env
option to docker run.We don't recommend that you use plaintext environment variables for sensitive information, such as credential data.
name
— (String
)The name of the key-value pair. For environment variables, this is the name of the environment variable.
value
— (String
)The value of the key-value pair. For environment variables, this is the value of the environment variable.
environmentFiles
— (Array<map>
)A list of files containing the environment variables to pass to a container. This parameter maps to the
--env-file
option to docker run.You can specify up to ten environment files. The file must have a
.env
file extension. Each line in an environment file contains an environment variable inVARIABLE=VALUE
format. Lines beginning with#
are treated as comments and are ignored.If there are environment variables specified using the
environment
parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide.value
— required — (String
)The Amazon Resource Name (ARN) of the Amazon S3 object containing the environment variable file.
type
— required — (String
)The file type to use. Environment files are objects in Amazon S3. The only supported value is
Possible values include:s3
."s3"
mountPoints
— (Array<map>
)The mount points for data volumes in your container.
This parameter maps to
Volumes

)Data volumes to mount from another container. This parameter maps to
VolumesFrom
in tthe docker create-container command and the--volumes-from
option to docker run.sourceContainer
— (String
)The name of another container within the same task definition to mount volumes from.
readOnly
— (Boolean

dependsOn
— (Array<map>
)The dependencies defined for container startup and shutdown. A container can contain multiple dependencies on other containers in a task definition. When a dependency is defined for container startup, for container shutdown it is reversed.
For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the
ecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
containerName

)The name of a container.
condition
— required — (String
)The dependency condition of the container. The following are the available conditions and their behavior:
-
START
- This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start. -
COMPLETE
- This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container. -
SUCCESS
- This condition is the same asCOMPLETE
, but it also requires that the container exits with azero
status. This condition can't be set on an essential container. -
HEALTHY
- This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.
"START"
"COMPLETE"
"SUCCESS"
"HEALTHY"
-
-
startTimeout
— (Integer
)Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a
COMPLETE
,SUCCESS
, orHEALTHY
status. If astartTimeout
value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to aSTOPPED
state.Note: When theECS_CONTAINER_START_TIMEOUT
container agent configuration variable is used, it's enforced independently from this start timeout value.For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
For tasks using the EC2 launch type, your container instances require at least version
1.26.0
of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version1.26.0-1
of theecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.The valid values for Fargate are 2-120 seconds.
-
stopTimeout
— (Integer
)Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks that use the EC2 launch type, if the
stopTimeout
parameter isn't specified, the value set for the Amazon ECS container agent configuration variableECS_CONTAINER_STOP_TIMEOUT
is used. If neither thestopTimeout
parameter or theECS_CONTAINER_STOP_TIMEOUT
agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of theecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.The valid values are 2-120 seconds.

This parameter maps to
LogConfig
in the docker create-container command and the--log-driver
option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options).Note: Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command:
sudo docker version --format '{{.Server.APIVersion}}'
Note: The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with theECS_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.logDriver
— required — (String

. For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide.Note: Tasks hosted on Fargate only support thefile
configuration file type.
credentialSpecs
— (Array<String>
)A list of ARNs in SSM or Amazon S3 to a credential spec (
CredSpec
) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of thedockerSecurityOptions
. The maximum number of ARNs is 1.There are two formats for each ARN.
- credentialspecdomainless:MyARN
-
You use
credentialspecdomainless:MyARN
to provide aCredSpec
with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.Each task that runs on any container instance can join different domains.
You can use this format without joining the container instance to a domain.
- credentialspec:MyARN
-
You use
credentialspec:MyARN
to provide aCredSpec
for a single domain.You must join the container instance to the domain before you start any tasks that use this task definition.
In both formats, replace
MyARN
with the ARN in SSM or Amazon S3.If you provide a
credentialspecdomainless:MyARN
, thecredspec
must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.
volumes
— (Array<map>
)A list of volume definitions in JSON format that containers in your task might use.
name
— (String
)The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.
When using a volume configured at launch, the
name
is required and must also be specified as the volume name in theServiceVolumeConfiguration
orTaskVolumeConfiguration
parameter when creating your service or standalone task.For all other types of volumes, this name is referenced in the
sourceVolume
parameter of themountPoints
object in the container definition.When a volume is using the
efsVolumeConfiguration
, the name is required.host
— (map
)This parameter is specified when you use bind mount host volumes. The contents of the
host
parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If thehost
parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.Windows containers can mount whole directories on the same drive as
$env:ProgramData
. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mountC:\my\path:C:\my\path
andD::D:\
, but notD:\my\path:C:\my\path
orD::C:\my\path
.sourcePath
— (String
)When the
host
parameter is used, specify asourcePath
to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If thehost
parameter contains asourcePath
file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If thesourcePath
value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.If you're using the Fargate launch type, the
sourcePath
parameter is not supported.
dockerVolumeConfiguration
— (map
)This parameter is specified when you use Docker volumes.
Windows containers only support the use of the
local

-
Maximum key length - 128 Unicode characters in UTF-8
-
Maximum value length - 256 Unicode characters in UTF-8
-
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
-
Tag keys and values are case-sensitive.
-
Do not use
aws:
,AWS:
, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
key

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

host
is specified, all containers within the tasks that specified thehost
PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance.If
task
is specified, all containers within the specified task share the same process namespace.If no value is specified, the default is a private namespace for each container.
If the
host
PID mode is used, there's a heightened risk of undesired process namespace exposure.Note: This parameter is not supported for Windows containers.Note: This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform versionPossible values include:1.4.0
or later (Linux). This isn't supported for Windows containers on Fargate."host"
"task"
ipcMode
— (String
)The IPC resource namespace to use for the containers in the task. The valid values are
host
,task
, ornone
. Ifhost
is specified, then all containers within the tasks that specified thehost
IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. Iftask
is specified, all containers within the specified task share the same IPC resources. Ifnone
is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance.If the
host
IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose.If you are setting namespaced kernel parameters using
systemControls
for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide.-
For tasks that use the
host
IPC mode, IPC namespace relatedsystemControls
are not supported. -
For tasks that use the
task

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)

containerDefinitions
— (Array<map>
)A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.
name
— (String
)The name of a container. If you're linking multiple containers together in a task definition, the
name
of one container can be entered in thelinks
of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps toname
in tthe docker create-container command and the--name
option to docker run.image
— (String
)The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either
repository-url/image:tag
orrepository-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 toImage
in the docker create-container command and theIMAGE
parameter of docker run.-
When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.
-
Images in Amazon ECR repositories can be specified by either using the full
registry/repository:tag
orregistry/repository@digest
. For example,012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest
or012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE
. -
Images in official repositories on Docker Hub use a single name (for example,
ubuntu
ormongo
). -
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.
credentialsParameter
— required — (String
)The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note: When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
cpu
— (Integer
)The number of
cpu
units reserved for the container. This parameter maps toCpuShares
in the docker create-container commandand the--cpu-shares
option to docker run.This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level
cpu
value.Note: You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. The minimum valid CPU share value that the Linux kernel allows is 2, and the maximum valid CPU share value that the Linux kernel allows is 262144. However, the CPU parameter isn't required, and you can use CPU values below 2 or above 262144 in your container definitions. For CPU values below 2 (including null) or above 262144, the behavior varies based on your Amazon ECS container agent version:
-
Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.
-
Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.
-
Agent versions greater than or equal to 1.84.0: CPU values greater than 256 vCPU are passed to Docker as 256, which is equivalent to 262144 CPU shares.
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as
0
, which Windows interprets as 1% of one CPU.-
memory
— (Integer
)The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task
memory
value, if one is specified. This parameter maps toMemory
in thethe docker create-container command and the--memory
option to docker run.If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level
memory
andmemoryReservation
value,memory
must be greater thanmemoryReservation
. If you specifymemoryReservation
, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value ofmemory
is used.The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
memoryReservation
— (Integer
)The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the
memory
parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps toMemoryReservation
in the the docker create-container command and the--memory-reservation
option to docker run.If a task-level memory value is not specified, you must specify a non-zero integer for one or both of
memory
ormemoryReservation
in a container definition. If you specify both,memory
must be greater thanmemoryReservation
. If you specifymemoryReservation
, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value ofmemory
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 amemory
hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
links
— (Array<String>
)The
links
parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition isbridge
. Thename:internalName
construct is analogous toname:alias
in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.. This parameter maps toLinks
in the docker create-container command and the--link
option to docker run.Note: This parameter is not supported for Windows containers.Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
portMappings
— (Array<map>
)The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the
awsvpc
network mode, only specify thecontainerPort
. ThehostPort
can be left blank or it must be the same value as thecontainerPort
.Port mappings on Windows use the
NetNAT
gateway address rather thanlocalhost
. There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.This parameter maps to
PortBindings
in the the docker create-container command and the--publish
option to docker run. If the network mode of a task definition is set tonone
, then you can't specify port mappings. If the network mode of a task definition is set tohost
, then host ports must either be undefined or they must match the container port in the port mapping.Note: After a task reaches theRUNNING
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 thenetworkBindings
section DescribeTasks responses.containerPort
— (Integer
)The port number on the container that's bound to the user-specified or automatically assigned host port.
If you use containers in a task with the
awsvpc
orhost
network mode, specify the exposed ports usingcontainerPort
.If you use containers in a task with the
bridge
network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, seehostPort
. Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.hostPort
— (Integer
)The port number on the container instance to reserve for your container.
If you specify a
containerPortRange
, leave this field empty and the value of thehostPort
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPort
is set to the same value as thecontainerPort
. This is a static mapping strategy. -
For containers in a task with the
bridge
network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.
If you use containers in a task with the
awsvpc
orhost
network mode, thehostPort
can either be left blank or set to the same value as thecontainerPort
.If you use containers in a task with the
bridge
network mode, you can specify a non-reserved host port for your container port mapping, or you can omit thehostPort
(or set it to0
) while specifying acontainerPort
and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under
/proc/sys/net/ipv4/ip_local_port_range
. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the
remainingResources
of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.-
protocol
— (String
)The protocol used for the port mapping. Valid values are
Possible values include:tcp
andudp
. The default istcp
.protocol
is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment."tcp"
"udp"
name
— (String
)The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the
serviceConnectConfiguration
of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
appProtocol
— (String
)The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.
If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.
appProtocol
is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
Possible values include:"http"
"http2"
"grpc"
containerPortRange

network mode. -
This parameter is available for both the EC2 and Fargate launch types.
-
This parameter is available for both the Linux and Windows operating systems.
-
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the
ecs-init
package -
You can specify a maximum of 100 port ranges per container.
-
You do not specify a
hostPortRange
. The value of thehostPortRange
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPortRange
is set to the same value as thecontainerPortRange
. This is a static mapping strategy. -
For containers in a task with the
bridge
network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
-
-
The
containerPortRange
valid values are between 1 and 65535. -
A port can only be included in one port mapping per container.
-
You cannot specify overlapping port ranges.
-
The first port in the range must be less than last port in the range.
-
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.
For more information, see Issue #11185 on the Github website.
For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.
You can call
DescribeTasks
to view thehostPortRange
which are the host ports that are bound to the container ports.-
essential

dependsOn
— (Array<map>
)The dependencies defined for container startup and shutdown. A container can contain multiple dependencies on other containers in a task definition. When a dependency is defined for container startup, for container shutdown it is reversed.
For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the
ecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.

"SUCCESS"
"HEALTHY"
-
-
startTimeout
— (Integer
)Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a
COMPLETE
,SUCCESS
, orHEALTHY
status. If astartTimeout
value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to aSTOPPED
state.Note: When theECS_CONTAINER_START_TIMEOUT
container agent configuration variable is used, it's enforced independently from this start timeout value.For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
For tasks using the EC2 launch type, your container instances require at least version
1.26.0
of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version1.26.0-1
of theecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.The valid values for Fargate are 2-120 seconds.
-
stopTimeout
— (Integer
)Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires the following platforms:
-
Linux platform version
1.3.0
or later. -
Windows platform version
1.0.0
or later.
The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks that use the EC2 launch type, if the
stopTimeout
parameter isn't specified, the value set for the Amazon ECS container agent configuration variableECS_CONTAINER_STOP_TIMEOUT
is used. If neither thestopTimeout
parameter or theECS_CONTAINER_STOP_TIMEOUT
agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of theecs-init
package. If your container instances are launched from version20190301
or later, then they contain the required versions of the container agent andecs-init
. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.The valid values are 2-120 seconds.

option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options).Note: Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command:
sudo docker version --format '{{.Server.APIVersion}}'
Note: The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with theECS_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.logDriver
— required — (String
)The log driver to use for the container.
For tasks on Fargate, the supported log drivers are

. For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide.Note: Tasks hosted on Fargate only support thefile
configuration file type.
credentialSpecs
— (Array<String>
)A list of ARNs in SSM or Amazon S3 to a credential spec (
CredSpec
) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of thedockerSecurityOptions
. The maximum number of ARNs is 1.There are two formats for each ARN.
- credentialspecdomainless:MyARN
-
You use
credentialspecdomainless:MyARN
to provide aCredSpec
with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.Each task that runs on any container instance can join different domains.
You can use this format without joining the container instance to a domain.
- credentialspec:MyARN
-
You use
credentialspec:MyARN
to provide aCredSpec
for a single domain.You must join the container instance to the domain before you start any tasks that use this task definition.
In both formats, replace
MyARN
with the ARN in SSM or Amazon S3.If you provide a
credentialspecdomainless:MyARN
, thecredspec
must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.
family
— (String
)The name of a family that this task definition is registered to. Up to 255 characters are allowed. Letters (both uppercase and lowercase letters), numbers, hyphens (-), and underscores (_) are allowed.
A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.
taskRoleArn
— (String
)The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.
executionRoleArn
— (String
)The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.
networkMode
— (String
)The Docker networking mode to use for the containers in the task. The valid values are
none
,bridge
,awsvpc
, andhost
. If no network mode is specified, the default isbridge
.For Amazon ECS tasks on Fargate, the
awsvpc
network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances,<default>
orawsvpc
can be used. If the network mode is set tonone
, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. Thehost
andawsvpc
network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by thebridge
mode.With the
host
andawsvpc
network modes, exposed container ports are mapped directly to the corresponding host port (for thehost
network mode) or the attached elastic network interface port (for theawsvpc
network mode), so you cannot take advantage of dynamic host port mappings.When using the
host
network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.If the network mode is
awsvpc
, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.If the network mode is
Possible values include:host
, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used."bridge"

. Each time that you register a new revision of a task definition in the same family, the revision value always increases by one. This is even if you deregistered previous revisions in this family.volumes
— (Array<map>
)The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide.
Note: Thehost

parameter when creating your service or standalone task.For all other types of volumes, this name is referenced in the
sourceVolume
parameter of themountPoints
object in the container definition.When a volume is using the
efsVolumeConfiguration
, the name is required.host
— (map
)This parameter is specified when you use bind mount host volumes. The contents of the
host
parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If thehost
parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.Windows containers can mount whole directories on the same drive as
$env:ProgramData
. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mountC:\my\path:C:\my\path
andD::D:\
, but notD:\my\path:C:\my\path
orD::C:\my\path
.sourcePath
— (String
)When the
host
parameter is used, specify asourcePath
to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If thehost
parameter contains asourcePath
file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If thesourcePath
value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.If you're using the Fargate launch type, the
sourcePath
parameter is not supported.
dockerVolumeConfiguration
— (map

runTask(params = {}, callback) ⇒ AWS.Request
Starts a new task using the specified task definition.
Note: On March 21, 2024, a change was made to resolve the task definition revision before authorization. When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.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.
Starting April 15, 2023, Amazon Web Services will not onboard new customers to Amazon Elastic Inference (EI), and will help current customers migrate their workloads to options that offer better price and performance. After April 15, 2023, new customers will not be able to launch instances with Amazon EI accelerators in Amazon SageMaker, Amazon ECS, or Amazon EC2. However, customers who have used Amazon EI at least once during the past 30-day period are considered current customers and will be able to continue using the service.
You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.
The Amazon ECS API follows an eventual consistency model. This is because of 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. 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.

This parameter is available for both the EC2 and Fargate launch types.
-
This parameter is available for both the Linux and Windows operating systems.
-
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the

You can specify a maximum of 100 port ranges per container.
-
You do not specify a
hostPortRange
. The value of thehostPortRange
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPortRange
is set to the same value as thecontainerPortRange
. This is a static mapping strategy. -
For containers in a task with the
bridge
network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
-
-
The
containerPortRange
valid values are between 1 and 65535. -
A port can only be included in one port mapping per container.
-
You cannot specify overlapping port ranges.
-
The first port in the range must be less than last port in the range.
-
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.
For more information, see Issue #11185 on the Github website.
For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.

When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.Starting April 15, 2023, Amazon Web Services will not onboard new customers to Amazon Elastic Inference (EI), and will help current customers migrate their workloads to options that offer better price and performance. After April 15, 2023, new customers will not be able to launch instances with Amazon EI accelerators in Amazon SageMaker, Amazon ECS, or Amazon EC2. However, customers who have used Amazon EI at least once during the past 30-day period are considered current customers and will be able to continue using the service.
Alternatively, you can use RunTask to place tasks for you. For more information, see Scheduling Tasks in the Amazon Elastic Container Service Developer Guide.
You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.

Returns:
stopTask(params = {}, callback) ⇒ AWS.Request
Stops a running task. Any tags associated with the task will be deleted.
When StopTask is called on a task, the equivalent of
docker stop
is issued to the containers running in the task. This results in aSIGTERM
value and a default 30-second timeout, after which theSIGKILL
value is sent and the containers are forcibly stopped. If the container handles theSIGTERM
value gracefully and exits within 30 seconds from receiving it, noSIGKILL
value is sent.For Windows containers, POSIX signals do not work and runtime stops the container by sending a
CTRL_SHUTDOWN_EVENT
. For more information, see Unable to react to graceful shutdown of (Windows) container #25982 on GitHub.Note: The default 30-second timeout can be configured on the Amazon ECS container agent with theECS_CONTAINER_STOP_TIMEOUT
variable. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.Service Reference:

. The value of thehostPortRange
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPortRange
is set to the same value as thecontainerPortRange
. This is a static mapping strategy. -
For containers in a task with the

network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
-
-
The
containerPortRange
valid values are between 1 and 65535. -
A port can only be included in one port mapping per container.
-
You cannot specify overlapping port ranges.
-
The first port in the range must be less than last port in the range.
-
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.
For more information, see Issue #11185 on the Github website.
For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.

0
and less than or equal to100
. For example, if you want the capacity provider to maintain 10% spare capacity, then that means the utilization is 90%, so use atargetCapacity
of90
. The default value of100
percent results in the Amazon EC2 instances in your Auto Scaling group being completely used.minimumScalingStepSize
— (Integer
)The minimum number of Amazon EC2 instances that Amazon ECS will scale out at one time. The scale in process is not affected by this parameter If this parameter is omitted, the default value of
1
is used.When additional capacity is required, Amazon ECS will scale up the minimum scaling step size even if the actual demand is less than the minimum scaling step size.
If you use a capacity provider with an Auto Scaling group configured with more than one Amazon EC2 instance type or Availability Zone, Amazon ECS will scale up by the exact minimum scaling step size value and will ignore both the maximum scaling step size as well as the capacity demand.

parameter totrue
in theServiceConnectConfiguration
. You can set the namespace of each service individually in theServiceConnectConfiguration
to override this default parameter.Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
namespace
— required — (String
)The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace that's used when you create a service and don't specify a Service Connect configuration.

If you enter an existing namespace name or ARN, then that namespace will be used. Any namespace type is supported. The namespace must be in this account and this Amazon Web Services Region.
If you enter a new name, a Cloud Map namespace will be created. Amazon ECS creates a Cloud Map namespace with the "API calls" method of instance discovery only. This instance discovery method is the "HTTP" namespace type in the Command Line Interface. Other types of instance discovery aren't used by Service Connect.
If you update the cluster with an empty string
""
for the namespace name, the cluster configuration for Service Connect is removed. Note that the namespace will remain in Cloud Map and must be deleted separately.For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide.

can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService
actions using the capacity provider strategy will fail.An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of
1
, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base

Returns:
updateContainerAgent(params = {}, callback) ⇒ AWS.Request
Updates the Amazon ECS container agent on a specified container instance. Updating the Amazon ECS container agent doesn't interrupt running tasks or services on the container instance. The process for updating the agent differs depending on whether your container instance was launched with the Amazon ECS-optimized AMI or another operating system.
Note: TheUpdateContainerAgent
API isn't supported for container instances using the Amazon ECS-optimized Amazon Linux 2 (arm64) AMI. To update the container agent, you can update theecs-init
package. This updates the agent. For more information, see Updating the Amazon ECS container agent in the Amazon Elastic Container Service Developer Guide.Note: Agent updates with theUpdateContainerAgent
API operation do not apply to Windows container instances. We recommend that you launch new container instances to update the agent version in your Windows clusters.The
UpdateContainerAgent
API requires an Amazon ECS-optimized AMI or Amazon Linux AMI with theecs-init
service installed and running. For help updating the Amazon ECS container agent on other operating systems, see Manually updating the Amazon ECS container agent in the Amazon Elastic Container Service Developer Guide.Service Reference:
Examples:
Calling the updateContainerAgent operation

Returns:
updateContainerInstancesState(params = {}, callback) ⇒ AWS.Request
Modifies the status of an Amazon ECS container instance.
Once a container instance has reached an
ACTIVE
state, you can change the status of a container instance toDRAINING
to manually remove an instance from a cluster, for example to perform system updates, update the Docker daemon, or scale down the cluster size.A container instance can't be changed to
DRAINING
until it has reached anACTIVE
status. If the instance is in any other status, an error will be received.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 thePENDING
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
andmaximumPercent
. You can change the deployment configuration of your service using UpdateService.-
If
minimumHealthyPercent
is below 100%, the scheduler can ignoredesiredCount
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're in theRUNNING
state. Tasks for services that use a load balancer are considered healthy if they're in theRUNNING
state and are reported as healthy by the load balancer. -
The
maximumPercent
parameter represents an upper limit on the number of running tasks during task replacement. You can use this to define the replacement batch size. For example, ifdesiredCount
is 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
orRUNNING
tasks that do not belong to a service aren't 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 a container instance has been drained, you can set a container instance to
ACTIVE
status and once it has reached that status the Amazon ECS scheduler can begin scheduling tasks on the instance again.Service Reference:

Returns:
updateService(params = {}, callback) ⇒ AWS.Request
Modifies the parameters of a service.
Note: On March 21, 2024, a change was made to resolve the task definition revision before authorization. When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.For services using the rolling update (
ECS
) you can update the desired count, deployment configuration, network configuration, load balancers, service registries, enable ECS managed tags option, propagate tags option, task placement constraints and strategies, and task definition. When you update any of these parameters, Amazon ECS starts new tasks with the new configuration.You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when starting or running a task, or when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide. You can update your volume configurations and trigger a new deployment.
volumeConfigurations
is only supported for REPLICA service and not DAEMON service. If you leavevolumeConfigurations
null
, it doesn't trigger a new deployment. For more infomation on volumes, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.For services using the blue/green (
CODE_DEPLOY
) deployment controller, only the desired count, deployment configuration, health check grace period, task placement constraints and strategies, enable ECS managed tags option, and propagate tags can be updated using this API. If the network configuration, platform version, task definition, or load balancer need to be updated, create a new CodeDeploy deployment. For more information, see CreateDeployment in the CodeDeploy API Reference.For services using an external deployment controller, you can update only the desired count, task placement constraints and strategies, health check grace period, enable ECS managed tags option, and propagate tags option, using this API. If the launch type, load balancer, network configuration, platform version, or task definition need to be updated, create a new task set For more information, see CreateTaskSet.
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.You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when starting or running a task, or when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.
If you have updated the container 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 don't need to create a new revision of your task definition. You can update the service using theforceNewDeployment
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
andmaximumPercent
, to determine the deployment strategy.-
If
minimumHealthyPercent
is below 100%, the scheduler can ignoredesiredCount
temporarily during a deployment. For example, ifdesiredCount
is four tasks, a minimum of 50% allows the scheduler to stop two existing tasks before starting two new tasks. Tasks for services that don't use a load balancer are considered healthy if they're in theRUNNING
state. Tasks for services that use a load balancer are considered healthy if they're in theRUNNING
state and are reported as healthy by the load balancer. -
The
maximumPercent
parameter represents an upper limit on the number of running tasks during a deployment. You can use it to define the deployment batch size. For example, ifdesiredCount
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 aSIGTERM
and a 30-second timeout. After this,SIGKILL
is sent and the containers are forcibly stopped. If the container handles theSIGTERM
gracefully and exits within 30 seconds from receiving it, noSIGKILL
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 even though 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.
Note: You must have a service-linked role when you update any of the following service properties:-
loadBalancers

Parameters:
-
params
(Object)
(defaults to: {})
—
cluster
— (String
)The short name or full Amazon Resource Name (ARN) of the cluster that your service runs 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
andrevision
(family:revision
) or full ARN of the task definition to run in your service. If arevision
is not specified, the latestACTIVE
revision is used. If you modify the task definition withUpdateService
, 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.capacityProviderStrategy
— (Array<map>
)The capacity provider strategy to update the service to use.
if the service uses the default capacity provider strategy for the cluster, the service can be updated to use one or more capacity providers as opposed to the default capacity provider strategy. However, when a service is using a capacity provider strategy that's not the default capacity provider strategy, the service can't be updated to use the cluster's default capacity provider strategy.
A capacity provider strategy consists of one or more capacity providers along with the
base
andweight
to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster. Only capacity providers with anACTIVE
orUPDATING
status can be used.If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the
FARGATE
orFARGATE_SPOT
capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.The PutClusterCapacityProviders API operation is used to update the list of available capacity providers for a cluster after the cluster is created.
capacityProvider
— required — (String
)The short name of the capacity provider.
weight
— (Integer
)The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The
weight
value is taken into consideration after thebase
value, if defined, is satisfied.If no
weight
value is specified, the default value of0
is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of0
can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService
actions using the capacity provider strategy will fail.An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of
1
, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base
— (Integer
)The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of
0
is used.
deploymentConfiguration
— (map
)Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker
— (map
)Note: The deployment circuit breaker can only be used for services using the rolling update (ECS
) deployment type.The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable
— required — (Boolean
)Determines whether to use the deployment circuit breaker logic for the service.
rollback
— required — (Boolean
)Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, themaximumPercent
parameter represents an upper limit on the number of your service's tasks that are allowed in theRUNNING
orPENDING
state during a deployment, as a percentage of thedesiredCount
(rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using theREPLICA
service scheduler and has adesiredCount
of four tasks and amaximumPercent
value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The defaultmaximumPercent
value for a service using theREPLICA
service scheduler is 200%.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.minimumHealthyPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, theminimumHealthyPercent
represents a lower limit on the number of your service's tasks that must remain in theRUNNING
state during a deployment, as a percentage of thedesiredCount
(rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has adesiredCount
of four tasks and aminimumHealthyPercent
of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.For services that do not use a load balancer, the following should be noted:
-
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
-
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a
RUNNING
state before the task is counted towards the minimum healthy percent total. -
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services that do use a load balancer, the following should be noted:
-
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
-
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
The default value for a replica service for
minimumHealthyPercent
is 100%. The defaultminimumHealthyPercent
value for a service using theDAEMON
service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.The minimum number of healthy tasks during a deployment is the
desiredCount
multiplied by theminimumHealthyPercent
/100, rounded up to the nearest integer value.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If a service is using either the blue/green (CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.-
alarms
— (map
)Information about the CloudWatch alarms.
alarmNames
— required — (Array<String>
)One or more CloudWatch alarm names. Use a "," to separate the alarms.
enable
— required — (Boolean
)Determines whether to use the CloudWatch alarm option in the service deployment process.
rollback
— required — (Boolean
)Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is used, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
networkConfiguration
— (map
)An object representing the network configuration for the service.
awsvpcConfiguration
— (map
)The VPC subnets and security groups that are associated with a task.
Note: All specified subnets and security groups must be from the same VPC.subnets
— required — (Array<String>
)The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per
AwsVpcConfiguration
.Note: All specified subnets must be from the same VPC.securityGroups
— (Array<String>
)The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per
AwsVpcConfiguration
.Note: All specified security groups must be from the same VPC.assignPublicIp
— (String
)Whether the task's elastic network interface receives a public IP address. The default value is
Possible values include:DISABLED
."ENABLED"
"DISABLED"
placementConstraints
— (Array<map>
)An array of task placement constraint objects to update the service to use. If no value is specified, the existing placement constraints for the service will remain unchanged. If this value is specified, it will override any existing placement constraints defined for the service. To remove all existing placement constraints, specify an empty array.
You can specify a maximum of 10 constraints for each task. This limit includes constraints in the task definition and those specified at runtime.
type
— (String
)The type of constraint. Use
Possible values include:distinctInstance
to ensure that each task in a particular group is running on a different container instance. UsememberOf
to restrict the selection to a group of valid candidates."distinctInstance"
"memberOf"
expression
— (String
)A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is
distinctInstance
. For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide.
placementStrategy
— (Array<map>
)The task placement strategy objects to update the service to use. If no value is specified, the existing placement strategy for the service will remain unchanged. If this value is specified, it will override the existing placement strategy defined for the service. To remove an existing placement strategy, specify an empty object.
You can specify a maximum of five strategy rules for each service.
type
— (String
)The type of placement strategy. The
Possible values include:random
placement strategy randomly places tasks on available candidates. Thespread
placement strategy spreads placement across available candidates evenly based on thefield
parameter. Thebinpack
strategy places tasks on available candidates that have the least available amount of the resource that's specified with thefield
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."random"
"spread"
"binpack"
field
— (String
)The field to apply the placement strategy against. For the
spread
placement strategy, valid values areinstanceId
(orhost
, which has the same effect), or any platform or custom attribute that's applied to a container instance, such asattribute:ecs.availability-zone
. For thebinpack
placement strategy, valid values arecpu
andmemory
. For therandom
placement strategy, this field is not used.
platformVersion
— (String
)The platform version that your tasks in the service run on. A platform version is only specified for tasks using the Fargate launch type. If a platform version is not specified, the
LATEST
platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.forceNewDeployment
— (Boolean
)Determines whether to force a new deployment of the service. By default, deployments aren't forced. You can use this option to start 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 ignores 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 2,147,483,647 seconds. During that time, the Amazon 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.
enableExecuteCommand
— (Boolean
)If
true
, this enables execute command functionality on all task containers.If you do not want to override the value that was set when the service was created, you can set this to
null
when performing this action.enableECSManagedTags
— (Boolean
)Determines whether to turn on Amazon ECS managed tags for the tasks in the service. For more information, see Tagging Your Amazon ECS Resources in the Amazon Elastic Container Service Developer Guide.
Only tasks launched after the update will reflect the update. To update the tags on all tasks, set
forceNewDeployment
totrue
, so that Amazon ECS starts new tasks with the updated tags.loadBalancers
— (Array<map>
)A list of Elastic Load Balancing load balancer objects. It contains the load balancer name, the container name, and the container port to access from the load balancer. The container name is as it appears in a container definition.
When you add, update, or remove a load balancer configuration, Amazon ECS starts new tasks with the updated Elastic Load Balancing configuration, and then stops the old tasks when the new tasks are running.
For services that use rolling updates, you can add, update, or remove Elastic Load Balancing target groups. You can update from a single target group to multiple target groups and from multiple target groups to a single target group.
For services that use blue/green deployments, you can update Elastic Load Balancing target groups by using
CreateDeployment
through CodeDeploy. Note that multiple target groups are not supported for blue/green deployments. For more information see Register multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.For services that use the external deployment controller, you can add, update, or remove load balancers by using CreateTaskSet. Note that multiple target groups are not supported for external deployments. For more information see Register multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.
You can remove existing
loadBalancers
by passing an empty list.targetGroupArn
— (String
)The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.
For services using the
ECS
deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.For services using the
CODE_DEPLOY
deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.If your service's task definition uses the
awsvpc
network mode, you must chooseip
as the target type, notinstance
. Do this when creating your target groups because tasks that use theawsvpc
network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.loadBalancerName
— (String
)The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName
— (String
)The name of the container (as it appears in a container definition) to associate with the load balancer.
You need to specify the container name when configuring the target group for an Amazon ECS load balancer.
containerPort
— (Integer
)The port on the container to associate with the load balancer. This port must correspond to a
containerPort
in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on thehostPort
of the port mapping.
propagateTags
— (String
)Determines whether to propagate the tags from the task definition or the service to the task. If no value is specified, the tags aren't propagated.
Only tasks launched after the update will reflect the update. To update the tags on all tasks, set
Possible values include:forceNewDeployment
totrue
, so that Amazon ECS starts new tasks with the updated tags."TASK_DEFINITION"
"SERVICE"
"NONE"
serviceRegistries
— (Array<map>
)The details for the service discovery registries to assign to this service. For more information, see Service Discovery.
When you add, update, or remove the service registries configuration, Amazon ECS starts new tasks with the updated service registries configuration, and then stops the old tasks when the new tasks are running.
You can remove existing
serviceRegistries
by passing an empty list.registryArn
— (String
)The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.
port
— (Integer
)The port value used if your service discovery service specified an SRV record. This field might be used if both the
awsvpc
network mode and SRV records are used.containerName
— (String
)The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the
bridge
orhost
network mode, you must specify acontainerName
andcontainerPort
combination from the task definition. If the task definition that your service task specifies uses theawsvpc
network mode and a type SRV DNS record is used, you must specify either acontainerName
andcontainerPort
combination or aport
value. However, you can't specify both.containerPort
— (Integer
)The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the
bridge
orhost
network mode, you must specify acontainerName
andcontainerPort
combination from the task definition. If the task definition your service task specifies uses theawsvpc
network mode and a type SRV DNS record is used, you must specify either acontainerName
andcontainerPort
combination or aport
value. However, you can't specify both.
serviceConnectConfiguration
— (map
)The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
enabled
— required — (Boolean
)Specifies whether to use Service Connect with this service.
namespace
— (String
)The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace for use with Service Connect. The namespace must be in the same Amazon Web Services Region as the Amazon ECS service and cluster. The type of namespace doesn't affect Service Connect. For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide.
services
— (Array<map>
)The list of Service Connect service objects. These are names and aliases (also known as endpoints) that are used by other Amazon ECS services to connect to this service.
This field is not required for a "client" Amazon ECS service that's a member of a namespace only to connect to other services within the namespace. An example of this would be a frontend application that accepts incoming requests from either a load balancer that's attached to the service or by other means.
An object selects a port from the task definition, assigns a name for the Cloud Map service, and a list of aliases (endpoints) and ports for client applications to refer to this service.
portName
— required — (String
)The
portName
must match the name of one of theportMappings
from all the containers in the task definition of this Amazon ECS service.discoveryName
— (String
)The
discoveryName
is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.If the
discoveryName
isn't specified, the port mapping name from the task definition is used inportName.namespace
.clientAliases
— (Array<map>
)The list of client aliases for this Service Connect service. You use these to assign names that can be used by client applications. The maximum number of client aliases that you can have in this list is 1.
Each alias ("endpoint") is a fully-qualified name and port number that other Amazon ECS tasks ("clients") can use to connect to this service.
Each name and port mapping must be unique within the namespace.
For each
ServiceConnectService
, you must provide at least oneclientAlias
with oneport
.port
— required — (Integer
)The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.
To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
dnsName
— (String
)The
dnsName
is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.If this parameter isn't specified, the default value of
discoveryName.namespace
is used. If thediscoveryName
isn't specified, the port mapping name from the task definition is used inportName.namespace
.To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are
database
,db
, or the lowercase name of a database, such asmysql
orredis
. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
ingressPortOverride
— (Integer
)The port number for the Service Connect proxy to listen on.
Use the value of this field to bypass the proxy for traffic on the port number specified in the named
portMapping
in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.In
awsvpc
mode and Fargate, the default value is the container port number. The container port number is in theportMapping
in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.timeout
— (map
)A reference to an object that represents the configured timeouts for Service Connect.
idleTimeoutSeconds
— (Integer
)The amount of time in seconds a connection will stay active while idle. A value of
0
can be set to disableidleTimeout
.The
idleTimeout
default forHTTP
/HTTP2
/GRPC
is 5 minutes.The
idleTimeout
default forTCP
is 1 hour.perRequestTimeoutSeconds
— (Integer
)The amount of time waiting for the upstream to respond with a complete response per request. A value of
0
can be set to disableperRequestTimeout
.perRequestTimeout
can only be set if Service ConnectappProtocol
isn'tTCP
. OnlyidleTimeout
is allowed forTCP
appProtocol
.
tls
— (map
)A reference to an object that represents a Transport Layer Security (TLS) configuration.
issuerCertificateAuthority
— required — (map
)The signer certificate authority.
awsPcaAuthorityArn

)The ARN of the Amazon Web Services Private Certificate Authority certificate.
kmsKey
— (String
)The Amazon Web Services Key Management Service key.
roleArn
— (String
)The Amazon Resource Name (ARN) of the IAM role that's associated with the Service Connect TLS.
logConfiguration
— (map
)The log configuration for the container. This parameter maps to
LogConfig
in the docker create-container command and the--log-driver
option to docker run.By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition.
Understand the following when specifying a log configuration for your containers.
-
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent.
For tasks on Fargate, the supported log drivers are
awslogs
,splunk
, andawsfirelens
.For tasks hosted on Amazon EC2 instances, the supported log drivers are
awslogs
,fluentd
,gelf
,json-file
,journald
,syslog
,splunk
, andawsfirelens
. -
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
-
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the
ECS_AVAILABLE_LOGGING_DRIVERS
environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide. -
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.
logDriver
— required — (String
)The log driver to use for the container.
For tasks on Fargate, the supported log drivers are
awslogs
,splunk
, andawsfirelens
.For tasks hosted on Amazon EC2 instances, the supported log drivers are
awslogs
,fluentd
,gelf
,json-file
,journald
,syslog
,splunk
, andawsfirelens
.For more information about using the
awslogs
log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.For more information about using the
awsfirelens
log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.Possible values include:"json-file"
"syslog"
"journald"
"gelf"
"fluentd"
"awslogs"
"splunk"
"awsfirelens"
options
— (map<String>
)The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command:
sudo docker version --format '{{.Server.APIVersion}}'
secretOptions
— (Array<map>
)The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide.

awsvpc
network mode, you must chooseip
as the target type, notinstance
. Do this when creating your target groups because tasks that use theawsvpc
network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.loadBalancerName
— (String
)The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName

)The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
capacityProvider
— required — (String
)The short name of the capacity provider.
weight
— (Integer
)The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The
weight
value is taken into consideration after thebase
value, if defined, is satisfied.If no
weight
value is specified, the default value of0
is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of0
can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService
actions using the capacity provider strategy will fail.An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of
1
, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base
— (Integer
)The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of
0
is used.
platformVersion

LATEST
platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.platformFamily
— (String
)The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.
All tasks that run as part of this service must use the same
platformFamily
value as the service (for example,LINUX
).taskDefinition
— (String
)The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
deploymentConfiguration
— (map
)Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker
— (map
)Note: The deployment circuit breaker can only be used for services using the rolling update (ECS
) deployment type.The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable
— required — (Boolean
)Determines whether to use the deployment circuit breaker logic for the service.
rollback
— required — (Boolean
)Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, themaximumPercent
parameter represents an upper limit on the number of your service's tasks that are allowed in theRUNNING
orPENDING
state during a deployment, as a percentage of thedesiredCount
(rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using theREPLICA
service scheduler and has adesiredCount
of four tasks and amaximumPercent
value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The defaultmaximumPercent
value for a service using theREPLICA
service scheduler is 200%.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.minimumHealthyPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, theminimumHealthyPercent
represents a lower limit on the number of your service's tasks that must remain in theRUNNING
state during a deployment, as a percentage of thedesiredCount
(rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has adesiredCount
of four tasks and aminimumHealthyPercent
of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.For services that do not use a load balancer, the following should be noted:
-
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
-
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a
RUNNING
state before the task is counted towards the minimum healthy percent total. -
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services that do use a load balancer, the following should be noted:
-
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
-
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
The default value for a replica service for
minimumHealthyPercent
is 100%. The defaultminimumHealthyPercent
value for a service using theDAEMON
service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.The minimum number of healthy tasks during a deployment is the
desiredCount
multiplied by theminimumHealthyPercent
/100, rounded up to the nearest integer value.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If a service is using either the blue/green (CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.-

-
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the
ECS_AVAILABLE_LOGGING_DRIVERS
environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide. -
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

updateTaskProtection(params = {}, callback) ⇒ AWS.Request
Updates the protection status of a task. You can set
protectionEnabled
totrue
to protect your task from termination during scale-in events from Service Autoscaling or deployments.Task-protection, by default, expires after 2 hours at which point Amazon ECS clears the
protectionEnabled
property making the task eligible for termination by a subsequent scale-in event.You can specify a custom expiration period for task protection from 1 minute to up to 2,880 minutes (48 hours). To specify the custom expiration period, set the
expiresInMinutes
property. TheexpiresInMinutes
property is always reset when you invoke this operation for a task that already hasprotectionEnabled
set totrue
. You can keep extending the protection expiration period of a task by invoking this operation repeatedly.To learn more about Amazon ECS task protection, see Task scale-in protection in the Amazon Elastic Container Service Developer Guide .
Note: This operation is only supported for tasks belonging to an Amazon ECS service. Invoking this operation for a standalone task will result in anTASK_NOT_VALID
failure. For more information, see API failure reasons.If you prefer to set task protection from within the container, we recommend using the Task scale-in protection endpoint.

network mode, thehostPortRange
is set to the same value as thecontainerPortRange
. This is a static mapping strategy. -
For containers in a task with the

-
-
The
containerPortRange
valid values are between 1 and 65535. -
A port can only be included in one port mapping per container.
-
You cannot specify overlapping port ranges.
-

This parameter is available for both the EC2 and Fargate launch types.
-
This parameter is available for both the Linux and Windows operating systems.
-
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the

package -
You can specify a maximum of 100 port ranges per container.
-
You do not specify a
hostPortRange
. The value of thehostPortRange
is set as follows:-
For containers in a task with the
awsvpc
network mode, thehostPortRange
is set to the same value as thecontainerPortRange
. This is a static mapping strategy. -
For containers in a task with the
bridge
network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
-
-
The
containerPortRange
valid values are between 1 and 65535. -
A port can only be included in one port mapping per container.
-
You cannot specify overlapping port ranges.
-
The first port in the range must be less than last port in the range.
-
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.
For more information, see Issue #11185 on the Github website.
For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.

can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService
actions using the capacity provider strategy will fail.An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of
1
, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base
— (Integer
)The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of
0
is used.
platformVersion
— (String
)The platform version to run your service on. A platform version is only specified for tasks that are hosted on Fargate. If one isn't specified, the
LATEST
platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.platformFamily
— (String
)The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.
All tasks that run as part of this service must use the same
platformFamily
value as the service (for example,LINUX
).taskDefinition
— (String
)The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
deploymentConfiguration
— (map
)Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker
— (map
)Note: The deployment circuit breaker can only be used for services using the rolling update (ECS
) deployment type.The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable
— required — (Boolean
)Determines whether to use the deployment circuit breaker logic for the service.
rollback
— required — (Boolean
)Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, themaximumPercent
parameter represents an upper limit on the number of your service's tasks that are allowed in theRUNNING
orPENDING
state during a deployment, as a percentage of thedesiredCount
(rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using theREPLICA
service scheduler and has adesiredCount
of four tasks and amaximumPercent
value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The defaultmaximumPercent
value for a service using theREPLICA
service scheduler is 200%.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.minimumHealthyPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, theminimumHealthyPercent
represents a lower limit on the number of your service's tasks that must remain in theRUNNING
state during a deployment, as a percentage of thedesiredCount
(rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has adesiredCount
of four tasks and aminimumHealthyPercent
of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.For services that do not use a load balancer, the following should be noted:
-
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
-
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a
RUNNING
state before the task is counted towards the minimum healthy percent total. -
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services that do use a load balancer, the following should be noted:
-
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
-
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
The default value for a replica service for
minimumHealthyPercent
is 100%. The defaultminimumHealthyPercent
value for a service using theDAEMON
service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.The minimum number of healthy tasks during a deployment is the
desiredCount
multiplied by theminimumHealthyPercent
/100, rounded up to the nearest integer value.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If a service is using either the blue/green (CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.-

LogConfig
in the docker create-container command and the--log-driver
option to docker run.By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition.
Understand the following when specifying a log configuration for your containers.
-
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent.
For tasks on Fargate, the supported log drivers are
awslogs
,splunk
, andawsfirelens
.For tasks hosted on Amazon EC2 instances, the supported log drivers are
awslogs
,fluentd
,gelf
,json-file
,journald
,syslog
,splunk
, andawsfirelens
. -
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
-
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the
ECS_AVAILABLE_LOGGING_DRIVERS
environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide. -
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

"ECS"
"CODE_DEPLOY"
"EXTERNAL"
tags

deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.If your service's task definition uses the
awsvpc
network mode, you must chooseip
as the target type, notinstance
. Do this when creating your target groups because tasks that use theawsvpc
network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.loadBalancerName
— (String
)The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName
— (String
)The name of the container (as it appears in a container definition) to associate with the load balancer.
You need to specify the container name when configuring the target group for an Amazon ECS load balancer.
containerPort
— (Integer
)The port on the container to associate with the load balancer. This port must correspond to a
containerPort
in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on thehostPort
of the port mapping.
serviceRegistries
— (Array<map>
)The details for the service discovery registries to assign to this service. For more information, see Service Discovery.
registryArn
— (String
)The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.

network mode and a type SRV DNS record is used, you must specify either acontainerName
andcontainerPort
combination or aport
value. However, you can't specify both.containerPort
— (Integer
)The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the
bridge
orhost
network mode, you must specify acontainerName
andcontainerPort
combination from the task definition. If the task definition your service task specifies uses theawsvpc
network mode and a type SRV DNS record is used, you must specify either acontainerName
andcontainerPort
combination or aport
value. However, you can't specify both.
status
— (String

RUNNING
state.pendingCount
— (Integer
)The number of tasks in the cluster that are in the
PENDING
state.launchType

Possible values include:"EC2"
"FARGATE"
"EXTERNAL"
capacityProviderStrategy
— (Array<map>
)The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
capacityProvider
— required — (String
)The short name of the capacity provider.
weight
— (Integer
)The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The
weight
value is taken into consideration after thebase
value, if defined, is satisfied.If no
weight
value is specified, the default value of0
is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of0
can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of0
, anyRunTask
orCreateService
actions using the capacity provider strategy will fail.An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of
1
, then when thebase
is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of1
for capacityProviderA and a weight of4
for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.base
— (Integer
)The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of
0
is used.

LATEST
platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.platformFamily
— (String
)The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.
All tasks that run as part of this service must use the same
platformFamily
value as the service (for example,LINUX
).taskDefinition
— (String
)The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
deploymentConfiguration
— (map
)Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker
— (map
)Note: The deployment circuit breaker can only be used for services using the rolling update (ECS
) deployment type.The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable
— required — (Boolean
)Determines whether to use the deployment circuit breaker logic for the service.
rollback
— required — (Boolean
)Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, themaximumPercent
parameter represents an upper limit on the number of your service's tasks that are allowed in theRUNNING
orPENDING
state during a deployment, as a percentage of thedesiredCount
(rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using theREPLICA
service scheduler and has adesiredCount
of four tasks and amaximumPercent
value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The defaultmaximumPercent
value for a service using theREPLICA
service scheduler is 200%.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING
state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.minimumHealthyPercent
— (Integer
)If a service is using the rolling update (
ECS
) deployment type, theminimumHealthyPercent
represents a lower limit on the number of your service's tasks that must remain in theRUNNING
state during a deployment, as a percentage of thedesiredCount
(rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has adesiredCount
of four tasks and aminimumHealthyPercent
of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.For services that do not use a load balancer, the following should be noted:
-
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
-
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a
RUNNING
state before the task is counted towards the minimum healthy percent total. -
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services that do use a load balancer, the following should be noted:
-
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
-
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
The default value for a replica service for
minimumHealthyPercent
is 100%. The defaultminimumHealthyPercent
value for a service using theDAEMON
service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.The minimum number of healthy tasks during a deployment is the
desiredCount
multiplied by theminimumHealthyPercent
/100, rounded up to the nearest integer value.If a service is using either the blue/green (
CODE_DEPLOY
) orEXTERNAL
deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in theRUNNING
state while the container instances are in theDRAINING

Understand the following when specifying a log configuration for your containers.
-
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent.
For tasks on Fargate, the supported log drivers are
awslogs

, andawsfirelens
. -
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
-
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the
ECS_AVAILABLE_LOGGING_DRIVERS
environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide. -
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

awslogs
log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide.For more information about using the
awsfirelens
log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner.Note: If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.Possible values include:"json-file"

There are two service scheduler strategies available.
-
REPLICA
-The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. -
DAEMON
-The daemon scheduling strategy deploys exactly one task on each active container instance. This task meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It stop tasks that don't meet the placement constraints.Note: Fargate tasks don't support theDAEMON
scheduling strategy.

deploymentController
— (map
)The deployment controller type the service is using.
type
— required — (String
)The deployment controller type to use.
There are three deployment controller types available:
- ECS
-
The rolling update (
ECS
) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration. - CODE_DEPLOY
-
The blue/green (
CODE_DEPLOY
) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it. - EXTERNAL
-
The external (
EXTERNAL
) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.
"ECS"
"CODE_DEPLOY"
"EXTERNAL"
tags
— (Array<map>
)The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value. You define bot the key and value.
The following basic restrictions apply to tags:
-
Maximum number of tags per resource - 50
-
For each resource, each tag key must be unique, and each tag key can have only one value.
-
Maximum key length - 128 Unicode characters in UTF-8
-
Maximum value length - 256 Unicode characters in UTF-8
-
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
-
Tag keys and values are case-sensitive.
-
Do not use
aws:
,AWS:
, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
