ScalableTarget

Represents a scalable target.

Contents

CreationTime

The Unix timestamp for when the scalable target was created.

Type: Timestamp

Required: Yes

MaxCapacity

The maximum value to scale to in response to a scale out event.

Type: Integer

Required: Yes

MinCapacity

The minimum value to scale to in response to a scale in event.

Type: Integer

Required: Yes

ResourceId

The identifier of the resource associated with the scalable target. 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.

Type: String

Required: Yes

RoleARN

The ARN of an IAM role that allows Application Auto Scaling to modify the scalable target on your behalf.

Type: String

ScalableDimension

The scalable dimension associated with the scalable target. 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.

Type: String

Valid Values: ecs:service:DesiredCount | ec2:spot-fleet-request:TargetCapacity | elasticmapreduce:instancegroup:InstanceCount | appstream:fleet:DesiredCapacity

Required: Yes

ServiceNamespace

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