CreateCapacityProvider

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 AWS Fargate use the FARGATE and FARGATE_SPOT capacity providers. These providers are available to all accounts in the AWS Regions that AWS Fargate supports.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

autoScalingGroupProvider

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

Type: AutoScalingGroupProvider object

Required: Yes

name

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".

Type: String

Required: Yes

tags

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

The following basic restrictions apply to tags:

Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for 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.

Type: Array of Tag objects

Array Members: Minimum number of 0 items. Maximum number of 50 items.

Required: No

Errors

For information about the errors that are common to all actions, see Common Errors.

ClientException

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

The following list includes additional causes for the error:

The RunTask could not be processed because you use managed scaling and there is a capacity error because the quota of tasks in the PROVISIONING per cluster has been reached. For information about the service quotas, see Amazon ECS service quotas.

HTTP Status Code: 400

InvalidParameterException

The specified parameter isn't valid. Review the available parameters for the API request.

HTTP Status Code: 400

LimitExceededException

The limit for the resource was exceeded.

HTTP Status Code: 400

ServerException

These errors are usually caused by a server issue.

HTTP Status Code: 500

UpdateInProgressException

There's already a current Amazon ECS container agent update in progress on the container instance that's specified. If the container agent becomes disconnected while it's in a transitional stage, such as PENDING or STAGING, the update process can get stuck in that state. However, when the agent reconnects, it resumes where it stopped previously.

HTTP Status Code: 400
