Error starting gcloud preview app setup-managed-vms

This command has been removed due to the fact that baseline images in real time are now publicly available in the Google Container registry.

They are available under: gcr.io/google_appengine/python-compat gcr.io/google_appengine/java-compat gcr.io/google_appengine/go-compat

They can be pulled out with the standard "docker bait"

If you replace google / appengine- * with these image names in the FROM line of your Dockerfile, docker will automatically pull them in during build and deploy.
