Update Maintenance Window Task

ssm_update_maintenance_window_task R Documentation

Modifies a task assigned to a maintenance window

Description

Modifies a task assigned to a maintenance window. You can't change the task type, but you can change the following values:

  • TaskARN. For example, you can change a RUN_COMMAND task from AWS-RunPowerShellScript to AWS-RunShellScript.

  • ServiceRoleArn

  • TaskInvocationParameters

  • Priority

  • MaxConcurrency

  • MaxErrors

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.

If the value for a parameter in update_maintenance_window_task is null, then the corresponding field isn't modified. If you set Replace to true, then all fields required by the register_task_with_maintenance_window operation are required for this request. Optional fields that aren't specified are set to null.

When you update a maintenance window task that has options specified in TaskInvocationParameters, you must provide again all the TaskInvocationParameters values that you want to retain. The values you don't specify again are removed. For example, suppose that when you registered a Run Command task, you specified TaskInvocationParameters values for Comment, NotificationConfig, and OutputS3BucketName. If you update the maintenance window task and specify only a different OutputS3BucketName value, the values for Comment and NotificationConfig are removed.

Usage

ssm_update_maintenance_window_task(WindowId, WindowTaskId, Targets,
  TaskArn, ServiceRoleArn, TaskParameters, TaskInvocationParameters,
  Priority, MaxConcurrency, MaxErrors, LoggingInfo, Name, Description,
  Replace, CutoffBehavior, AlarmConfiguration)

Arguments

WindowId

[required] The maintenance window ID that contains the task to modify.

WindowTaskId

[required] The task ID to modify.

Targets

The targets (either managed nodes or tags) to modify. Managed nodes are specified using the format ⁠Key=instanceids,Values=instanceID_1,instanceID_2⁠. Tags are specified using the format ⁠ Key=tag_name,Values=tag_value⁠.

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.

TaskArn

The task ARN to modify.

ServiceRoleArn

The Amazon Resource Name (ARN) of the IAM service role for Amazon Web Services Systems Manager to assume when running a maintenance window task. If you do not specify a service role ARN, Systems Manager uses a service-linked role in your account. If no appropriate service-linked role for Systems Manager exists in your account, it is created when you run register_task_with_maintenance_window.

However, for an improved security posture, we strongly recommend creating a custom policy and custom service role for running your maintenance window tasks. The policy can be crafted to provide only the permissions needed for your particular maintenance window tasks. For more information, see Setting up maintenance windows in the in the Amazon Web Services Systems Manager User Guide.

TaskParameters

The parameters to modify.

TaskParameters has been deprecated. To specify parameters to pass to a task when it runs, instead use the Parameters option in the TaskInvocationParameters structure. For information about how Systems Manager handles these options for the supported maintenance window task types, see MaintenanceWindowTaskInvocationParameters.

The map has the following format:

Key: string, between 1 and 255 characters

Value: an array of strings, each string is between 1 and 255 characters

TaskInvocationParameters

The parameters that the task should use during execution. Populate only the fields that match the task type. All other fields should be empty.

When you update a maintenance window task that has options specified in TaskInvocationParameters, you must provide again all the TaskInvocationParameters values that you want to retain. The values you don't specify again are removed. For example, suppose that when you registered a Run Command task, you specified TaskInvocationParameters values for Comment, NotificationConfig, and OutputS3BucketName. If you update the maintenance window task and specify only a different OutputS3BucketName value, the values for Comment and NotificationConfig are removed.

Priority

The new task priority to specify. The lower the number, the higher the priority. Tasks that have the same priority are scheduled in parallel.

MaxConcurrency

The new MaxConcurrency value you want to specify. MaxConcurrency is the number of targets that are allowed to run this task, in parallel.

Although this element is listed as "Required: No", a value can be omitted only when you are registering or updating a targetless task You must provide a value in all other cases.

For maintenance window tasks without a target specified, you can't supply a value for this option. Instead, the system inserts a placeholder value of 1. This value doesn't affect the running of your task.

MaxErrors

The new MaxErrors value to specify. MaxErrors is the maximum number of errors that are allowed before the task stops being scheduled.

Although this element is listed as "Required: No", a value can be omitted only when you are registering or updating a targetless task You must provide a value in all other cases.

For maintenance window tasks without a target specified, you can't supply a value for this option. Instead, the system inserts a placeholder value of 1. This value doesn't affect the running of your task.

LoggingInfo

The new logging location in Amazon S3 to specify.

LoggingInfo has been deprecated. To specify an Amazon Simple Storage Service (Amazon S3) bucket to contain logs, instead use the OutputS3BucketName and OutputS3KeyPrefix options in the TaskInvocationParameters structure. For information about how Amazon Web Services Systems Manager handles these options for the supported maintenance window task types, see MaintenanceWindowTaskInvocationParameters.

Name

The new task name to specify.

Description

The new task description to specify.

Replace

If True, then all fields that are required by the register_task_with_maintenance_window operation are also required for this API request. Optional fields that aren't specified are set to null.

CutoffBehavior

Indicates whether tasks should continue to run after the cutoff time specified in the maintenance windows is reached.

  • CONTINUE_TASK: When the cutoff time is reached, any tasks that are running continue. The default value.

  • CANCEL_TASK:

    • For Automation, Lambda, Step Functions tasks: When the cutoff time is reached, any task invocations that are already running continue, but no new task invocations are started.

    • For Run Command tasks: When the cutoff time is reached, the system sends a cancel_command operation that attempts to cancel the command associated with the task. However, there is no guarantee that the command will be terminated and the underlying process stopped.

    The status for tasks that are not completed is TIMED_OUT.

AlarmConfiguration

The CloudWatch alarm you want to apply to your maintenance window task.
