Updates an association. You can update the association name and version, the document version, schedule, parameters, and Amazon Simple Storage Service (Amazon S3) output. When you call UpdateAssociation, the system removes all optional parameters from the request and overwrites the association with null values for those parameters. This is by design. You must specify all optional parameters in the call, even if you are not changing the parameters. This includes the Name parameter. Before calling this API action, we recommend that you call the DescribeAssociation API operation and make a note of all optional parameters required for your UpdateAssociation call.

In order to call this API operation, a user, group, or role must be granted permission to call the DescribeAssociation API operation. If you don't have permission to call DescribeAssociation, then you receive the following error:

An error occurred (AccessDeniedException) when calling the UpdateAssociation operation: User: isn't authorized to perform: ssm:DescribeAssociation on resource:

When you update an association, the association immediately runs against the specified targets. You can add the ApplyOnlyAtCronInterval parameter to run the association during the next schedule run.
