Association

Describes an association of a AWS Systems Manager document (SSM document) and a managed node.

AssociationId

The ID created by the system when you create an association. An association is a binding between a document and a set of targets with a schedule.

Type: String

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}

Required: No

AssociationName

The association name.

Type: String

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

Required: No

AssociationVersion

The association version.

Type: String

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

Required: No

DocumentVersion

The version of the document used in the association. If you change a document version for a State Manager association, Systems Manager immediately runs the association unless you previously specifed the apply-only-at-cron-interval parameter.

Important

State Manager doesn't support running associations that use a new version of a document if that document is shared from another account. State Manager always runs the default version of a document if shared from another account, even though the Systems Manager console shows that a new version was processed. If you want to run an association using a new version of a document shared form another account, you must set the document version to default.

Type: String

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

Required: No

Duration

The number of hours that an association can run on specified targets. After the resulting cutoff time passes, associations that are currently running are cancelled, and no pending executions are started on remaining targets.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 24.

Required: No

InstanceId

The managed node ID.

Type: String

Pattern: (^i-(\w{8}|\w{17})$)|(^mi-\w{17}$)

Required: No

LastExecutionDate

The date on which the association was last run.

Type: Timestamp

Required: No

Name

The name of the SSM document.

Type: String

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

Required: No

ScheduleOffset

Number of days to wait after the scheduled day to run an association.
