get-maintenance-window-task¶

Description¶

Lists the tasks in a maintenance window.

Synopsis¶

  get-maintenance-window-task
--window-id <value>
--window-task-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--window-id (string)

The maintenance window ID that includes the task to retrieve.

--window-task-id (string)

The maintenance window task ID to retrieve.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Output¶

WindowId -> (string)

The retrieved maintenance window ID.

WindowTaskId -> (string)

The retrieved maintenance window task ID.

Targets -> (list)

The targets where the task should run.

(structure)

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* ``

(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* ``

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

(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.

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

Key -> (string)

User-defined criteria for sending commands that target instances that meet the criteria.

Values -> (list)

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 .

(string)

TaskArn -> (string)

The resource that the task used during execution. For RUN_COMMAND and AUTOMATION task types, the TaskArn is the Systems Manager Document name/ARN. For LAMBDA tasks, the value is the function name/ARN. For STEP_FUNCTIONS tasks, the value is the state machine ARN.
