Target class

An array of search criteria that targets instances using a Key,Value combination that you specify. Supported formats include the following.

  • Key=InstanceIds,Values=instance-id-1,instance-id-2,instance-id-3
  • Key=tag:my-tag-key,Values=my-tag-value-1,my-tag-value-2
  • Key=tag-key,Values=my-tag-key-1,my-tag-key-2
  • Run Command and Maintenance window targets only: Key=resource-groups:Name,Values=resource-group-name
  • Maintenance window targets only: Key=resource-groups:ResourceTypeFilters,Values=resource-type-1,resource-type-2
  • Automation targets only: Key=ResourceGroup;Values=resource-group-name
For example:
  • Key=InstanceIds,Values=i-02573cafcfEXAMPLE,i-0471e04240EXAMPLE,i-07782c72faEXAMPLE
  • Key=tag:CostCenter,Values=CostCenter1,CostCenter2,CostCenter3
  • Key=tag-key,Values=Name,Instance-Type,CostCenter
  • Run Command and Maintenance window targets only: Key=resource-groups:Name,Values=ProductionResourceGroup

    This example demonstrates how to target all resources in the resource group ProductionResourceGroup in your maintenance window.

  • Maintenance window targets only: Key=resource-groups:ResourceTypeFilters,Values=AWS::EC2::INSTANCE,AWS::EC2::VPC

    This example demonstrates how to target only EC2 instances and VPCs in your maintenance window.

  • Automation targets only: Key=ResourceGroup,Values=MyResourceGroup
  • State Manager association targets only: Key=InstanceIds,Values=*

    This example demonstrates how to target all managed instances in the AWS Region where the association was created.

For more information about how to send commands that target instances using Key,Value parameters, see Targeting multiple instances in the AWS Systems Manager User Guide.

Properties

hashCode → int
The hash code for this object.
no setterinherited
key → String?
User-defined criteria for sending commands that target instances that meet the criteria.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
values → List<String>?
User-defined criteria that maps to Key. For example, if you specified tag:ServerRole, you could specify value:WebServer to run a command on instances that include EC2 tags of ServerRole,WebServer.
