Reference documentation and code samples for the Compute Engine v1 API enum InstanceGroupManagerUpdatePolicy.Types.MinimalAction.
Minimal action to be taken on an instance. Use this option to minimize disruption as much as possible or to apply a more disruptive action than is necessary. - To limit disruption as much as possible, set the minimal action to REFRESH. If your update requires a more disruptive action, Compute Engine performs the necessary action to execute the update. - To apply a more disruptive action than is strictly necessary, set the minimal action to RESTART or REPLACE. For example, Compute Engine does not need to restart a VM to change its metadata. But if your application reads instance metadata only when a VM is restarted, you can set the minimal action to RESTART in order to pick up metadata changes.
Additional supported values which may be not listed in the enum directly due to technical reasons:
NONE
REFRESH
REPLACE
RESTART
