create-cluster

Description

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

Note

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

See 'aws help' for descriptions of global parameters.

Synopsis

  create-cluster
[--cluster-name <value>]
[--tags <value>]
[--settings <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--cluster-name (string)

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

--tags (list)

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

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 AWS 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.

Shorthand Syntax:

key=string,value=string ...

JSON Syntax:

[
  {
    "key": "string",
    "value": "string"
  }
  ...
]

--settings (list)

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

Shorthand Syntax:

name=string,value=string ...

JSON Syntax:

[
  {
    "name": "containerInsights",
    "value": "string"
  }
  ...
]

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. 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 create a new cluster

The following create-cluster example creates a cluster.

aws ecs create-cluster --cluster-name MyCluster

Output:

{
    "cluster": {
        "clusterArn": "arn:aws:ecs:us-west-2:123456789012:cluster/MyCluster",
        "clusterName": "MyCluster",
        "status": "ACTIVE",
        "registeredContainerInstancesCount": 0,
        "pendingTasksCount": 0,
        "runningTasksCount": 0,
        "activeServicesCount": 0,
        "statistics": [],
        "tags": []
    }
}

Example 2: To create a new cluster with multiple tags

The following create-cluster example creates a cluster with multiple tags. For more information about adding tags using shorthand syntax, see Using Shorthand Syntax with the AWS Command Line Interface in the AWS CLI User Guide.

aws ecs create-cluster \
    --cluster-name MyCluster \
    --tags key=key1,value=value1 key=key2,value=value2 key=key3,value=value3

Output:

{
    "cluster": {
        "clusterArn": "arn:aws:ecs:us-west-2:123456789012:cluster/MyCluster",
        "clusterName": "MyCluster",
        "status": "ACTIVE",
        "registeredContainerInstancesCount": 0,
        "pendingTasksCount": 0,
        "runningTasksCount": 0,
        "activeServicesCount": 0,
        "statistics": [],
        "tags": [
            {
                "key": "key1",
                "value": "value1"
            },
            {
                "key": "key2",
                "value": "value2"
            },
            {
                "key": "key3",
                "value": "value3"
            }
        ]
    }
}

Output

cluster -> (structure)

The full description of your new cluster.

clusterArn -> (string)

The Amazon Resource Name (ARN) that identifies the cluster. The ARN contains the arn:aws:ecs namespace, followed by the Region of the cluster, the AWS account ID of the cluster owner, the cluster namespace, and then the cluster name. For example, arn:aws:ecs:region:012345678910:cluster/test .
