Parameters:

  • InstanceIds (list) –

    The IDs of the managed nodes where the command should run. Specifying managed node IDs is most useful when you are targeting a limited number of managed nodes, though you can specify up to 50 IDs.

    To target a larger number of managed nodes, or if you prefer not to list individual node IDs, we recommend using the Targets option instead. Using Targets, which accepts tag key-value pairs to identify the managed nodes to send commands to, you can a send command to tens, hundreds, or thousands of nodes at once.

    For more information about how to use targets, see Run commands at scale in the Amazon Web Services Systems Manager User Guide.

    • (string) –

  • Targets (list) –

    An array of search criteria that targets managed nodes using a Key,Value combination that you specify. Specifying targets is most useful when you want to send a command to a large number of managed nodes at once. Using Targets, which accepts tag key-value pairs to identify managed nodes, you can send a command to tens, hundreds, or thousands of nodes at once.

    To send a command to a smaller number of managed nodes, you can use the InstanceIds option instead.

    For more information about how to use targets, see Run commands at scale in the Amazon Web Services Systems Manager User Guide.

    • (dict) –

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

      Note

      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.

      • Key (string) –

        User-defined criteria for sending commands that target managed nodes 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.

    [REQUIRED]

    The name of the Amazon Web Services Systems Manager document (SSM document) to run. This can be a public document or a custom document. To run a shared document belonging to another account, specify the document Amazon Resource Name (ARN). For more information about how to use shared documents, see Sharing SSM documents in the Amazon Web Services Systems Manager User Guide.

    Note

    If you specify a document name or ARN that hasn’t been shared with your account, you receive an InvalidDocument error.

  • DocumentVersion (string) –

    The SSM document version to use in the request. You can specify $DEFAULT, $LATEST, or a specific version number. If you run commands by using the Command Line Interface (Amazon Web Services CLI), then you must escape the first two options by using a backslash. If you specify a version number, then you don’t need to use the backslash. For example:

    –document-version “$DEFAULT”

    –document-version “$LATEST”

    –document-version “3”

  • DocumentHash (string) –

    The Sha256 or Sha1 hash created by the system when the document was created.

    The required and optional parameters specified in the document being run.

    • (string) –

      • (list) –

        • (string) –

  • OutputS3Region (string) – (Deprecated) You can no longer specify this parameter. The system ignores it. Instead, Systems Manager automatically determines the Amazon Web Services Region of the S3 bucket.

  • OutputS3KeyPrefix (string) – The directory structure within the S3 bucket where the responses should be stored.

  • MaxConcurrency (string) – (Optional) The maximum number of managed nodes that are allowed to run the command at the same time. You can specify a number such as 10 or a percentage such as 10%. The default value is 50. For more information about how to use MaxConcurrency, see Using concurrency controls in the Amazon Web Services Systems Manager User Guide.

  • MaxErrors (string) – The maximum number of errors allowed without the command failing. When the command fails one more time beyond the value of MaxErrors, the systems stops sending the command to additional targets. You can specify a number like 10 or a percentage like 10%. The default value is 0. For more information about how to use MaxErrors, see Using error controls in the Amazon Web Services Systems Manager User Guide.

  • ServiceRoleArn (string) –

      The type of notification.

      • Command: Receive notification when the status of a command changes.

      • Invocation: For commands sent to multiple managed nodes, receive notification on a per-node basis when the status of a command changes.

    • CloudWatchOutputEnabled (boolean) –

      Enables Systems Manager to send command output to CloudWatch Logs.
