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 automation.

Type: AlarmConfiguration object

Required: No

ClientToken

User-provided idempotency token. The token must be unique, is case insensitive, enforces the UUID format, and can't be reused.

Type: String

Length Constraints: Fixed length of 36.

Pattern: [a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{12}

Required: No

DocumentName

The name of the 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 ARN. For more information about how to use shared documents, see Sharing SSM documents in the AWS Systems Manager User Guide.

Type: String

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

Required: Yes

DocumentVersion

The version of the Automation runbook to use for this execution.

Type: String

Pattern: ([$]LATEST|[$]DEFAULT|^[1-9][0-9]*$)

Required: No

MaxConcurrency

The maximum number of targets allowed to run this task in parallel. You can specify a number, such as 10, or a percentage, such as 10%. The default value is 10.

If both this parameter and the TargetLocation:TargetsMaxConcurrency are supplied, TargetLocation:TargetsMaxConcurrency takes precedence.

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 number of errors that are allowed before the system stops running the automation on additional targets. You can specify either an absolute number of errors, for example 10, or a percentage of the target set, for example 10%. If you specify 3, for example, the system stops running the automation when the fourth error is received. If you specify 0, then the system stops running the automation on additional targets after the first error result is returned. If you run an automation on 50 resources and set max-errors to 10%, then the system stops running the automation on additional targets when the sixth error is received.

Executions that are already running an automation when max-errors is reached are allowed to complete, but some of these executions may fail as well. If you need to ensure that there won't be more than max-errors failed executions, set max-concurrency to 1 so the executions proceed one at a time.

If this parameter and the TargetLocation:TargetsMaxErrors parameter are both supplied, TargetLocation:TargetsMaxErrors takes precedence.

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

Mode

The execution mode of the automation. Valid modes include the following: Auto and Interactive. The default mode is Auto.

Type: String

Valid Values: Auto | Interactive

Required: No

Parameters

A key-value map of execution parameters, which match the declared parameters in the Automation runbook.

Type: String to array of strings map

Map Entries: Maximum number of 200 items.

Key Length Constraints: Minimum length of 1. Maximum length of 50.

Array Members: Minimum number of 0 items. Maximum number of 50 items.

Length Constraints: Minimum length of 1. Maximum length of 512.

Required: No

Tags

Optional metadata that you assign to a resource. You can specify a maximum of five tags for an automation. Tags enable you to categorize a resource in different ways, such as by purpose, owner, or environment. For example, you might want to tag an automation to identify an environment or operating system. In this case, you could specify the following key-value pairs:

Key=environment,Value=test
Key=OS,Value=Windows

Note

To add tags to an existing automation, use the AddTagsToResource operation.

Type: Array of Tag objects

Array Members: Maximum number of 1000 items.

Required: No

TargetLocations

A location is a combination of AWS Regions and/or AWS accounts where you want to run the automation. Use this operation to start an automation in multiple AWS Regions and multiple AWS accounts. For more information, see Running automations in multiple AWS Regions and accounts in the AWS Systems Manager User Guide.

Type: Array of TargetLocation objects

Array Members: Minimum number of 1 item. Maximum number of 100 items.

Required: No

TargetLocationsURL

Specify a publicly accessible URL for a file that contains the TargetLocations body. Currently, only files in presigned Amazon S3 buckets are supported.

Type: String

Pattern: ^https:\/\/[-a-zA-Z0-9@:%._\+~#=]{1,253}\.s3(\.[a-z\d-]{9,16})?\.amazonaws\.com\/.{1,2000}

Required: No

TargetMaps

A key-value mapping of document parameters to target resources. Both Targets and TargetMaps can't be specified together.

Type: Array of string to array of strings maps

Array Members: Minimum number of 0 items. Maximum number of 300 items.

Map Entries: Maximum number of 20 items.

Key Length Constraints: Minimum length of 1. Maximum length of 50.

Array Members: Minimum number of 0 items. Maximum number of 25 items.

Length Constraints: Minimum length of 1. Maximum length of 50.

Required: No

TargetParameterName

The name of the parameter used as the target resource for the rate-controlled execution. Required if you specify targets.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 50.

Required: No

Targets

A key-value mapping to target resources. Required if you specify TargetParameterName.

If both this parameter and the TargetLocation:Targets parameter are supplied, TargetLocation:Targets takes precedence.

Type: Array of Target objects

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

Required: No
