I\'m running a Google Kubernetes Engine with the \"private-cluster\" option. I\'ve also defined \"authorized Master Network\" to be able to remotely access the environment -
It's currently not possible to add Cloud Build machines to a VPC. Similarly, Cloud Build does not announce IP ranges of the build machines. So you can't do this today without creating a "ssh bastion instance" or a "proxy instance" on GCE within that VPC.
I suspect this would change soon. GCB existed before GKE private clusters and private clusters are still a beta feature.
