[ aws . application-autoscaling ]

put-scheduled-action

Description

Creates or updates a scheduled action for an Application Auto Scaling scalable target.

Each scalable target is identified by a service namespace, resource ID, and scalable dimension. A scheduled action applies to the scalable target identified by those three attributes. You cannot create a scheduled action without first registering a scalable target using register-scalable-target .

To update an action, specify its name and the parameters that you want to change. If you don't specify start and end times, the old values are deleted. Any other parameters that you don't specify are not changed by this update request.

You can view the scheduled actions using describe-scheduled-actions . If you are no longer using a scheduled action, you can delete it using delete-scheduled-action .

Options

--service-namespace (string)

The namespace of the AWS service. For more information, see AWS Service Namespaces in the Amazon Web Services General Reference .

Possible values:

  • ecs
  • elasticmapreduce
  • ec2
  • appstream
  • dynamodb
  • rds

--schedule (string)

The schedule for this action. The following formats are supported:

  • At expressions - at(*yyyy* -*mm* -*dd* T*hh* :*mm* :*ss* )
  • Rate expressions - rate(*value*  *unit* )
  • Cron expressions - cron(*fields* )

At expressions are useful for one-time schedules. Specify the time, in UTC.

For rate expressions, value is a positive integer and unit is minute | minutes | hour | hours | day | days .

For more information about cron expressions, see Cron .

--scheduled-action-name (string)

The name of the scheduled action.

--resource-id (string)

The identifier of the resource associated with the scheduled action. This string consists of the resource type and unique identifier.

  • ECS service - The resource type is service and the unique identifier is the cluster name and service name. Example: service/default/sample-webapp .
  • Spot fleet request - The resource type is spot-fleet-request and the unique identifier is the Spot fleet request ID. Example: spot-fleet-request/sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE .
  • EMR cluster - The resource type is instancegroup and the unique identifier is the cluster ID and instance group ID. Example: instancegroup/j-2EEZNYKUA1NTV/ig-1791Y4E1L8YI0 .
  • AppStream 2.0 fleet - The resource type is fleet and the unique identifier is the fleet name. Example: fleet/sample-fleet .
  • DynamoDB table - The resource type is table and the unique identifier is the resource ID. Example: table/my-table .
  • DynamoDB global secondary index - The resource type is index and the unique identifier is the resource ID. Example: table/my-table/index/my-table-index .
  • Aurora DB cluster - The resource type is cluster and the unique identifier is the cluster name. Example: cluster:my-db-cluster .

--scalable-dimension (string)

The scalable dimension. This string consists of the service namespace, resource type, and scaling property.

  • ecs:service:DesiredCount - The desired task count of an ECS service.
  • ec2:spot-fleet-request:TargetCapacity - The target capacity of a Spot fleet request.
  • elasticmapreduce:instancegroup:InstanceCount - The instance count of an EMR Instance Group.
  • appstream:fleet:DesiredCapacity - The desired capacity of an AppStream 2.0 fleet.
  • dynamodb:table:ReadCapacityUnits - The provisioned read capacity for a DynamoDB table.
  • dynamodb:table:WriteCapacityUnits - The provisioned write capacity for a DynamoDB table.
  • dynamodb:index:ReadCapacityUnits - The provisioned read capacity for a DynamoDB global secondary index.
  • dynamodb:index:WriteCapacityUnits - The provisioned write capacity for a DynamoDB global secondary index.
  • rds:cluster:ReadReplicaCount - The count of Aurora Replicas in an Aurora DB cluster. Available for Aurora MySQL-compatible edition.

Possible values:

  • ecs:service:DesiredCount
  • ec2:spot-fleet-request:TargetCapacity
  • elasticmapreduce:instancegroup:InstanceCount
  • appstream:fleet:DesiredCapacity
  • dynamodb:table:ReadCapacityUnits
  • dynamodb:table:WriteCapacityUnits
  • dynamodb:index:ReadCapacityUnits
  • dynamodb:index:WriteCapacityUnits
  • rds:cluster:ReadReplicaCount

--start-time (timestamp)

The date and time for the scheduled action to start.

--end-time (timestamp)

The date and time for the scheduled action to end.

--scalable-target-action (structure)

The new minimum and maximum capacity. You can set both values or just one. During the scheduled time, if the current capacity is below the minimum capacity, Application Auto Scaling scales out to the minimum capacity. If the current capacity is above the maximum capacity, Application Auto Scaling scales in to the maximum capacity.

Shorthand Syntax:

MinCapacity=integer,MaxCapacity=integer

JSON Syntax:

{
  "MinCapacity": integer,
  "MaxCapacity": integer
}

--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.

--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.
