Parameters:

    [REQUIRED]

    The name of the Automation runbook to run. The result of the execution preview indicates what the impact would be of running this runbook.

  • DocumentVersion (string) – The version of the Automation runbook to run. The default value is $DEFAULT.

  • ExecutionInputs (dict) –

    Information about the inputs that can be specified for the preview operation.

    Note

    This is a Tagged Union structure. Only one of the following top level keys can be set: Automation.

    • Automation (dict) –

      Information about the optional inputs that can be specified for an automation execution preview.

      • Parameters (dict) –

        Information about parameters that can be specified for the preview operation.

          • (list) –

            • (string) –

        The name of the parameter used as the target resource for the rate-controlled execution. Required if you specify targets.

      • Targets (list) –

          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.
