RegisterScalableTargetInput

import "github.com/aws/aws-sdk-go/service/applicationautoscaling"

type RegisterScalableTargetInput struct { MaxCapacity *int64 `type:"integer"` MinCapacity *int64 `type:"integer"` ResourceId *string `min:"1" type:"string" required:"true"` RoleARN *string `min:"1" type:"string"` ScalableDimension *string `type:"string" required:"true" enum:"ScalableDimension"` ServiceNamespace *string `type:"string" required:"true" enum:"ServiceNamespace"` }

MaxCapacity

Type: *int64

The maximum value to scale to in response to a scale-out event. This parameter is required to register a scalable target.

MinCapacity

Type: *int64

The minimum value to scale to in response to a scale-in event. This parameter is required to register a scalable target.

ResourceId

Type: *string

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.

  • 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.

  • Amazon SageMaker endpoint variants - The resource type is variant and the unique identifier is the resource ID. Example: endpoint/my-end-point/variant/KMeansClustering.

  • Custom resources are not supported with a resource type. This parameter must specify the OutputValue from the CloudFormation template stack used to access the resources. The unique identifier is defined by the service provider. More information is available in our GitHub repository (https://github.com/aws/aws-auto-scaling-custom-resource).

ResourceId is a required field

RoleARN

Type: *string

Application Auto Scaling creates a service-linked role that grants it permissions to modify the scalable target on your behalf. For more information, see Service-Linked Roles for Application Auto Scaling (https://docs.aws.amazon.com/autoscaling/application/userguide/application-auto-scaling-service-linked-roles.html).

For resources that are not supported using a service-linked role, this parameter is required and must specify the ARN of an IAM role that allows Application Auto Scaling to modify the scalable target on your behalf.

ScalableDimension

Type: *string

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.

  • 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 and Aurora PostgreSQL-compatible edition.

  • sagemaker:variant:DesiredInstanceCount - The number of EC2 instances for an Amazon SageMaker model endpoint variant.

  • custom-resource:ResourceType:Property - The scalable dimension for a custom resource provided by your own application or service.

ScalableDimension is a required field

ServiceNamespace

Type: *string

The namespace of the AWS service that provides the resource or custom-resource for a resource provided by your own application or service. For more information, see AWS Service Namespaces (https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html#genref-aws-service-namespaces) in the Amazon Web Services General Reference.

ServiceNamespace is a required field
