Is it possible to connect to the Google Cloud Shell instance via the ssh? Maybe somehow with gcloud? So I can use it with my favorite terminal (iTerm in particular) and not with the Web-based shell.
Answer: yes it is now been possible: https://cloud.google.com/blog/products/gcp/introducing-the-ability-to-connect-to-cloud-shell-from-any-terminal
When you start Cloud Shell, it provisions an f1-micro Google Compute Engine virtual machine running a Debian-based Linux operating system. Cloud Shell instances are provisioned on a per-user, per-session basis. The instance persists while your Cloud Shell session is active and terminates after an hour of inactivity.
