agentVersion

The default AWS OpsWorks Stacks agent version. You have the following options:

• Auto-update - Set this parameter to LATEST. AWS OpsWorks Stacks automatically installs new agent versions on the stack's instances as soon as they are available.

• Fixed version - Set this parameter to your preferred agent version. To update the agent version, you must edit the stack configuration and specify a new version. AWS OpsWorks Stacks then automatically installs that version on the stack's instances.

The default setting is LATEST. To specify an agent version, you must use the complete version number, not the abbreviated number shown on the console. For a list of available agent version numbers, call DescribeAgentVersions. AgentVersion cannot be set to Chef 12.2.

You can also specify an agent version when you create or update an instance, which overrides the stack's default setting.
