AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

A State Manager association defines the state that you want to maintain on your managed nodes. For example, an association can specify that anti-virus software must be installed and running on your managed nodes, or that certain ports must be closed. For static targets, the association specifies a schedule for when the configuration is reapplied. For dynamic targets, such as an Amazon Web Services resource group or an Amazon Web Services autoscaling group, State Manager, a capability of Amazon Web Services Systems Manager applies the configuration when new managed nodes are added to the group. The association also specifies actions to take when applying the configuration. For example, an association for anti-virus software might run once a day. If the software isn't installed, then State Manager installs it. If the software is installed, but the service isn't running, then the association might instruct State Manager to start the service.

Note:

For .NET Core this operation is only available in asynchronous form. Please refer to CreateAssociationAsync.

Syntax

C#
public abstract CreateAssociationResponse CreateAssociation(
         String instanceId,
         String name
)

Parameters

instanceId
Type: System.String

The managed node ID. InstanceId has been deprecated. To specify a managed node ID for an association, use the Targets parameter. Requests that include the parameter InstanceID with Systems Manager documents (SSM documents) that use schema version 2.0 or later will fail. In addition, if you use the parameter InstanceId, you can't use the parameters AssociationName, DocumentVersion, MaxErrors, MaxConcurrency, OutputLocation, or ScheduleExpression. To use these parameters, you must use the Targets parameter.

name
Type: System.String

The name of the SSM Command document or Automation runbook that contains the configuration information for the managed node. You can specify Amazon Web Services-predefined documents, documents you created, or a document that is shared with you from another Amazon Web Services account. For Systems Manager documents (SSM documents) that are shared with you from other Amazon Web Services accounts, you must specify the complete SSM document ARN, in the following format: arn:partition:ssm:region:account-id:document/document-name For example: arn:aws:ssm:us-east-2:12345678912:document/My-Shared-Document For Amazon Web Services-predefined documents and SSM documents you created in your account, you only need to specify the document name. For example, AWS-ApplyPatchBaseline or My-Document.

Return Value


The response from the CreateAssociation service method, as returned by SimpleSystemsManagement.
