Synopsis

Invokes the RegisterScalableTarget operation against Application Auto Scaling.

Syntax

Add-AASScalableTarget
-ServiceNamespace <ServiceNamespace>
-MaxCapacity <Int32>
-MinCapacity <Int32>
-ResourceId <String>
-RoleARN <String>
-ScalableDimension <ScalableDimension>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

Registers or updates a scalable target. A scalable target is a resource that Application Auto Scaling can scale out or scale in. After you have registered a scalable target, you can use this operation to update the minimum and maximum values for your scalable dimension. After you register a scalable target, you can create and apply scaling policies using PutScalingPolicy. You can view the scaling policies for a service namespace using DescribeScalableTargets. If you are no longer using a scalable target, you can deregister it using DeregisterScalableTarget.

Parameters

-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?False
-MaxCapacity <Int32>
The maximum value to scale to in response to a scale out event. This parameter is required if you are registering a scalable target and optional if you are updating one.
Required?False
Position?Named
Accept pipeline input?False
-MinCapacity <Int32>
The minimum value to scale to in response to a scale in event. This parameter is required if you are registering a scalable target and optional if you are updating one.
Required?False
Position?Named
Accept pipeline input?False
-PassThru <SwitchParameter>
Returns the value passed to the ServiceNamespace parameter. By default, this cmdlet does not generate any output.
Required?False
Position?Named
Accept pipeline input?False
-ResourceId <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.
Required?False
Position?Named
Accept pipeline input?False
-RoleARN <String>
The ARN of an IAM role that allows Application Auto Scaling to modify the scalable target on your behalf. This parameter is required when you register a scalable target and optional when you update one.
Required?False
Position?Named
Accept pipeline input?False
-ScalableDimension <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.
  • 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.
Required?False
Position?Named
Accept pipeline input?False
-ServiceNamespace <ServiceNamespace>
The namespace of the AWS service. For more information, see AWS Service Namespaces in the Amazon Web Services General Reference.
Required?False
Position?1
Accept pipeline input?True (ByValue, )

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? False
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? False
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? False

Inputs

You can pipe a ServiceNamespace object to this cmdlet for the ServiceNamespace parameter.

Outputs

None or Amazon.ApplicationAutoScaling.ServiceNamespace
When you use the PassThru parameter, this cmdlet outputs the value supplied to the ServiceNamespace parameter. Otherwise, this cmdlet does not return any output. The service response (type Amazon.ApplicationAutoScaling.Model.RegisterScalableTargetResponse) can be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
