Target

An array of search criteria that targets managed nodes using a key-value pair that you specify.

One or more targets must be specified for maintenance window Run Command-type tasks. Depending on the task, targets are optional for other maintenance window task types (Automation, Lambda, and Step Functions). For more information about running tasks that don't specify targets, see Registering maintenance window tasks without targets in the Amazon Web Services Systems Manager User Guide.

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=ProductionResourceGroupThis 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::VPCThis example demonstrates how to target only Amazon Elastic Compute Cloud (Amazon 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 Amazon Web Services Region where the association was created.

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