Reference documentation and code samples for the Compute Engine v1 API enum InstanceGroupManagerUpdatePolicy.Types.MostDisruptiveAllowedAction.
Most disruptive action that is allowed to be taken on an instance. You can specify either NONE to forbid any actions, REFRESH to avoid restarting the VM and to limit disruption as much as possible. RESTART to allow actions that can be applied without instance replacing or REPLACE to allow all possible actions. If the Updater determines that the minimal update action needed is more disruptive than most disruptive allowed action you specify it will not perform the update at all.
Additional supported values which may be not listed in the enum directly due to technical reasons:
NONE
REFRESH
REPLACE
RESTART
