Parameter options for the register-task-with-maintenance-windows command

The register-task-with-maintenance-window command provides several options for configuring a task according to your needs. Some are required, some are optional, and some apply to only a single maintenance window task type.

This topic provides information about some of these options to help you work with samples in this tutorial section. For information about all command options, see register-task-with-maintenance-window in the Amazon CLI Command Reference.

Command option: --task-arn

The option --task-arn is used to specify the resource that the task operates on. The value that you specify depends on the type of task you're registering, as described in the following table.

TaskArn formats for maintenance window tasks
Maintenance window task type TaskArn value

RUN_COMMAND and AUTOMATION

TaskArn is the SSM document name or Amazon Resource Name (ARN). For example:

AWS-RunBatchShellScript

-or-

arn:aws-cn:ssm:region:111122223333:document/My-Document.

LAMBDA

TaskArn is the function name or ARN. For example:

SSMMy-Lambda-Function

-or-

arn:aws-cn:lambda:region:111122223333:function:SSMMyLambdaFunction.

Important

The IAM policy for Maintenance Windows requires that you add the prefix SSM to Lambda function (or alias) names. Before you proceed to register this type of task, update its name in Amazon Lambda to include SSM. For example, if your Lambda function name is MyLambdaFunction, change it to SSMMyLambdaFunction.

STEP_FUNCTIONS

TaskArn is the state machine ARN. For example:

arn:aws:states:us-east-2:111122223333:stateMachine:SSMMyStateMachine.

Important

The IAM policy for maintenance windows requires that you prefix Step Functions state machine names with SSM. Before you register this type of task, you must update its name in Amazon Step Functions to include SSM. For example, if your state machine name is MyStateMachine, change it to SSMMyStateMachine.
Command option: --service-role-arn

The role for Amazon Systems Manager to assume when running the maintenance window task.

Command option: --task-invocation-parameters

The --task-invocation-parameters option is used to specify the parameters that are unique to each of the four task types. The supported parameters for each of the four task types are described in the following table.

Note

For information about using pseudo parameters in --task-invocation-parameters content, such as {{TARGET_ID}}, see Using pseudo parameters when registering maintenance window tasks.
