put-cluster-capacity-providers¶

Description¶

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.

Synopsis¶

  put-cluster-capacity-providers
--cluster <value>
--capacity-providers <value>
--default-capacity-provider-strategy <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--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.

--capacity-providers (list)

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 or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.

(string)

Syntax:

"string" "string" ...

--default-capacity-provider-strategy (list)

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

If 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 or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.

(structure)

The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.

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

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

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

capacityProvider -> (string)

The short name of the capacity provider.

weight -> (integer)

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

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

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

base -> (integer)

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

Shorthand Syntax:

capacityProvider=string,weight=integer,base=integer ...

JSON Syntax:

[
  {
    "capacityProvider": "string",
    "weight": integer,
    "base": integer
  }
  ...
]

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Example 1: To add an existing capacity provider to a cluster

The following put-cluster-capacity-providers example adds an existing capacity provider to a cluster. The create-capacity-provider command is used to create a capacity provider. The describe-clusters command is used to describe the current capacity providers and the default capacity provider strategy associated with a cluster. When adding a new capacity provider to a cluster, you must specify all existing capacity providers in addition to the new capacity provider you want to associate with the cluster. You must also specify the default capacity provider strategy to associate with the cluster. In this example, the MyCluster cluster has the MyCapacityProvider1 capacity provider associated with it and you want to add the MyCapacityProvider2 capacity provider and include it in the default capacity provider strategy so tasks are spread evenly across both capacity providers.

aws ecs put-cluster-capacity-providers \
    --cluster MyCluster \
    --capacity-providers MyCapacityProvider1 MyCapacityProvider2 \
    --default-capacity-provider-strategy capacityProvider=MyCapacityProvider1,weight=1 capacityProvider=MyCapacityProvider2,weight=1

Example 2: To remove a capacity provider from a cluster

The following put-cluster-capacity-providers example removes a capacity provider from a cluster. The describe-clusters command is used to describe the current capacity providers associated with a cluster. When removing a capacity provider from a cluster, you must specify the capacity providers you want to remain associated with the cluster as well as the default capacity provider strategy to associate with the cluster. In this example, the cluster has the MyCapacityProvider1 and MyCapacityProvider2 capacity providers associated with it and you want to remove the MyCapacityProvider2 capacity provider, so you specify only MyCapacityProvider1 in the command along with the updated default capacity provider strategy.

aws ecs put-cluster-capacity-providers \
    --cluster MyCluster \
    --capacity-providers MyCapacityProvider1 \
    --default-capacity-provider-strategy capacityProvider=MyCapacityProvider1,weight=1,base=0

The settings for the cluster. This parameter indicates whether CloudWatch Container Insights is enabled or disabled for a cluster.

(structure)

The settings to use when creating a cluster. This parameter is used to enable CloudWatch Container Insights for a cluster.

name -> (string)

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

value -> (string)

The value to set for the cluster setting. The supported values are enabled and disabled . If enabled is specified, CloudWatch Container Insights will be enabled for the cluster, otherwise it will be disabled unless the containerInsights account setting is enabled. If a cluster value is specified, it will override the containerInsights value set with PutAccountSetting or PutAccountSettingDefault .

capacityProviders -> (list)

The capacity providers associated with the cluster.

(string)

defaultCapacityProviderStrategy -> (list)

The default capacity provider strategy for the cluster. When services or tasks are run in the cluster with no launch type or capacity provider strategy specified, the default capacity provider strategy is used.

(structure)

The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.

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

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

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

capacityProvider -> (string)

The short name of the capacity provider.

weight -> (integer)

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

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

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

base -> (integer)

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

attachments -> (list)

The resources attached to a cluster. When using a capacity provider with a cluster, the Auto Scaling plan that’s created is returned as a cluster attachment.

(structure)

An object representing a container instance or task attachment.

id -> (string)

The unique identifier for the attachment.

type -> (string)

The type of the attachment, such as ElasticNetworkInterface .

status -> (string)

The status of the attachment. Valid values are PRECREATED , CREATED , ATTACHING , ATTACHED , DETACHING , DETACHED , DELETED , and FAILED .

details -> (list)

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

(structure)

A key-value pair object.

name -> (string)

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

value -> (string)

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

attachmentsStatus -> (string)

The status of the capacity providers associated with the cluster. The following are the states that are returned.

UPDATE_IN_PROGRESS

The available capacity providers for the cluster are updating. This occurs when the Auto Scaling plan is provisioning or deprovisioning.

UPDATE_COMPLETE

The capacity providers have successfully updated.

UPDATE_FAILED

The capacity provider updates failed.
