UpdateMaintenanceWindowTask

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

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, AWS Lambda, and AWS Step Functions). For more information about running tasks that don't specify targets, see Registering maintenance window tasks without targets in the AWS Systems Manager User Guide.

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

Important

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.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

AlarmConfiguration

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

Type: AlarmConfiguration object

Required: No

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, AWS Lambda, AWS 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 CancelCommand 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.

Type: String

Valid Values: CONTINUE_TASK | CANCEL_TASK

Required: No

Description

The new task description to specify.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Required: No

LoggingInfo

The new logging location in Amazon S3 to specify.

Note

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 AWS Systems Manager handles these options for the supported maintenance window task types, see MaintenanceWindowTaskInvocationParameters.

Type: LoggingInfo object

Required: No

MaxConcurrency

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

Note

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.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 7.

Pattern: ^([1-9][0-9]*|[1-9][0-9]%|[1-9]%|100%)$

Required: No

MaxErrors

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

Note

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.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 7.

Pattern: ^([1-9][0-9]*|[0]|[1-9][0-9]%|[0-9]%|100%)$

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

For more information, see the following topics in the in the AWS Systems Manager User Guide:

• Using service-linked roles for Systems Manager

• Should I use a service-linked role or a custom service role to run maintenance window tasks?

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, AWS Lambda, and AWS Step Functions). For more information about running tasks that don't specify targets, see Registering maintenance window tasks without targets in the AWS Systems Manager User Guide.

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.
