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

ClientToken

User-provided idempotency token.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

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, Amazon Lambda, Amazon 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

An optional description for the task.

Type: String

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

Required: No

LoggingInfo

A structure containing information about an Amazon Simple Storage Service (Amazon S3) bucket to write managed node-level logs to.

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

Type: LoggingInfo object

Required: No

MaxConcurrency

The maximum number of targets this task can be run for, 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 maximum number of errors allowed before this 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.

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%)$

Required: No

Name

An optional name for the task.

Type: String

Length Constraints: Minimum length of 3. Maximum length of 128.

Pattern: ^[a-zA-Z0-9_\-.]{3,128}$

Required: No

Priority

The priority of the task in the maintenance window, the lower the number the higher the priority. Tasks in a maintenance window are scheduled in priority order with tasks that have the same priority scheduled in parallel.

Type: Integer

Valid Range: Minimum value of 0.

Required: No

ServiceRoleArn

The Amazon Resource Name (ARN) of the IAM service role for Amazon 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 RegisterTaskWithMaintenanceWindow.

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 Systems Manager User Guide.

Type: String

Required: No

Targets

The targets (either managed nodes or maintenance window targets).

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

Specify managed nodes using the following format:

Key=InstanceIds,Values=<instance-id-1>,<instance-id-2>

Specify maintenance window targets using the following format:

Key=WindowTargetIds,Values=<window-target-id-1>,<window-target-id-2>

Type: Array of Target objects

Array Members: Minimum number of 0 items. Maximum number of 5 items.

Required: No

TaskArn

The ARN of the task to run.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1600.

Required: Yes

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.

Type: MaintenanceWindowTaskInvocationParameters object

Required: No

TaskParameters

The parameters that should be passed to the task when it is run.

Note

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.

Type: String to MaintenanceWindowTaskParameterValueExpression object map

Key Length Constraints: Minimum length of 1. Maximum length of 255.

Required: No

TaskType

The type of task being registered.

Type: String

Valid Values: RUN_COMMAND | AUTOMATION | STEP_FUNCTIONS | LAMBDA

Required: Yes

WindowId

The ID of the maintenance window the task should be added to.

Type: String

Length Constraints: Fixed length of 20.

Pattern: ^mw-[0-9a-f]{17}$

Required: Yes

Response Syntax


{
   "WindowTaskId": "string"
}

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

WindowTaskId

The ID of the task in the maintenance window.

Type: String

Length Constraints: Fixed length of 36.

Pattern: ^[0-9a-fA-F]{8}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{12}$

Errors

For information about the errors that are common to all actions, see Common Errors.

DoesNotExistException

Error returned when the ID specified for a resource, such as a maintenance window or patch baseline, doesn't exist.

For information about resource quotas in Amazon Systems Manager, see Systems Manager service quotas in the Amazon Web Services General Reference.
