I have created two virtual machines and want to use load balancer having these two virtual machines.
But I could see GCP is insisting to creating template first and then instance group. But I am looking for something without the creation of template, since I already have two virtual machine to be used by the load balancer.
You don't need to create a template if you use an "Unmanaged instance group", but yo do need to create an unmanaged instance group to use a load balancer.
