At first when creating a compute engine managed instance group, the form allow to select the instance group type Managed or unmanaged.
Under managed compute engine instance group, we have option to select stateful or stateless, but after creating the instance group. I do not see the group information stateful or stateless.
Tried with command, no luck:
gcloud compute instance-groups list | describe
Please suggest, thanks.
In console, in Instance groups, Group type will be set as "Stateful" or "Managed".
Using commands, however, is a bit tricky. The best I could find is to list instances in group and check disk autodelete setting:
Statefull instances will have this set to false, stateless will be true.
You can suggest adding this information to cloud compute instance-groups describe in public issue tracker.
