get-maintenance-window-task¶

Description¶

Lists the tasks in a maintenance window.

Note

For maintenance window tasks without a specified target, you cannot supply values for --max-errors and --max-concurrency . Instead, the system inserts a placeholder value of 1 , which may be reported in the response to this command. These values do not affect the running of your task and can be ignored.

Synopsis¶

  get-maintenance-window-task
--window-id <value>
--window-task-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--window-id (string)

The maintenance window ID that includes the task to retrieve.

--window-task-id (string)

The maintenance window task ID to retrieve.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

The retrieved maintenance window task ID.

Targets -> (list)

The targets where the task should run.

(structure)

An array of search criteria that targets instances using a Key,Value combination 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, AWS Lambda, and AWS Step Functions). For more information about running tasks that do not specify targets, see Registering maintenance window tasks without targets in the AWS Systems Manager User Guide .

Supported formats include the following.

``Key=InstanceIds,Values=*instance-id-1* ,*instance-id-2* ,*instance-id-3* ``

``Key=tag:my-tag-key ,Values=*my-tag-value-1* ,*my-tag-value-2* ``

``Key=tag-key,Values=*my-tag-key-1* ,*my-tag-key-2* ``

Run Command and Maintenance window targets only : ``Key=resource-groups:Name,Values=*resource-group-name* ``

Maintenance window targets only : ``Key=resource-groups:ResourceTypeFilters,Values=*resource-type-1* ,*resource-type-2* ``

Automation targets only : ``Key=ResourceGroup;Values=*resource-group-name* ``

For example:

Key=InstanceIds,Values=i-02573cafcfEXAMPLE,i-0471e04240EXAMPLE,i-07782c72faEXAMPLE

Key=tag:CostCenter,Values=CostCenter1,CostCenter2,CostCenter3

Key=tag-key,Values=Name,Instance-Type,CostCenter

Run Command and Maintenance window targets only : Key=resource-groups:Name,Values=ProductionResourceGroup This example demonstrates how to target all resources in the resource group ProductionResourceGroup in your maintenance window.

Maintenance window targets only : ``Key=resource-groups:ResourceTypeFilters,Values=*AWS::EC2::INSTANCE* ,*AWS::EC2::VPC* `` This example demonstrates how to target only EC2 instances and VPCs in your maintenance window.

Automation targets only : Key=ResourceGroup,Values=MyResourceGroup

State Manager association targets only : Key=InstanceIds,Values=* This example demonstrates how to target all managed instances in the AWS Region where the association was created.

For more information about how to send commands that target instances using Key,Value parameters, see Targeting multiple instances in the AWS Systems Manager User Guide .

–document-version “$LATEST”

—document-version “3”

The different events for which you can receive notifications. These events include the following: All (events), InProgress, Success, TimedOut, Cancelled, Failed. To learn more about these events, see Monitoring Systems Manager status changes using Amazon SNS notifications in the AWS Systems Manager User Guide .

Note

For maintenance window tasks without a target specified, you cannot supply a value for this option. Instead, the system inserts a placeholder value of 1 , which may be reported in the response to this command. This value does not affect the running of your task and can be ignored.
