AWS::SSM::MaintenanceWindowTask Target - AWS CloudFormation

AWS::SSM::MaintenanceWindowTask Target

The Target property type specifies targets (either instances or window target IDs). You specify instances by using Key=InstanceIds,Values=<instanceid1>,<instanceid2>. You specify window target IDs using Key=WindowTargetIds,Values=<window-target-id-1>,<window-target-id-2> for a maintenance window task in AWS Systems Manager.

Target is a property of the AWS::SSM::MaintenanceWindowTask property type.

Note

To use resource-groups:Name as the key for a maintenance window target, specify the resource group as a AWS::SSM::MaintenanceWindowTarget type, and use the Ref function to specify the target for AWS::SSM::MaintenanceWindowTask. For an example, see Create a Run Command task that targets instances using a resource group name in AWS::SSM::MaintenanceWindowTask Examples.
