Reference documentation and code samples for the Compute Engine v1 API enum InstanceGroupManagersApplyUpdatesRequest.Types.MostDisruptiveAllowedAction.
The most disruptive action that you want to perform on each instance during the update: - REPLACE: Delete the instance and create it again. - RESTART: Stop the instance and start it again. - REFRESH: Do not stop the instance. - NONE: Do not disrupt the instance at all. By default, the most disruptive allowed action is REPLACE. If your update requires a more disruptive action than you set with this flag, the update request will fail.
Additional supported values which may be not listed in the enum directly due to technical reasons:
NONE
REFRESH
REPLACE
RESTART
