Disclosure: I work on Google Cloud (and Preemptible VMs). You’re kind of racing against the clock though. You could instead have a “load balancing” style layer in front, so that while there is no usable session, at least the person’s connection is just “hanging”. Feel free to send me some email, as we’re looking to make this experience better (both generally and in GKE, specifically).
