Dear Team
as i am new to this .. please excuse me if this is a basic query..
i am trying to understand how to create a instance group .. when we have a custom VM which has some Apps / libraries / software installed.. for now my understanding is instance groups can only use instance templates.. and when we configure instance templates its just the VM configuration with a startup script .. but what if we need a VM which has preinstalled setup / apps etc ... can i use a preconfigured VM to create Managed instance group .. i want instance group to create and manage my VMs and do not want to select Vms created as a separate step.
Please advise.
