I don't follow you. You are talking about GCP compute machines - right? I went with the default install-config.yaml and there were 3 worker nodes and 3 master node. See the snippet, below from the config file:
- hyperthreading: Enabled
I did observe them being up and running. And without any such machines being available, I don't think my install would have reached 99%, so you probably meant something else when you said "....you have no compute machines associated with your cluster". If I'm looking in the wrong direction, please point me in the right direction.
