gke-auto-sandbox's Issues

Update to use Spot VMs

GKE docs say...

Spot VMs are the latest version of preemptible VMs. GKE continues to support preemptible VMs, which now use the same pricing model as Spot VMs.

Use preemptible VMs to run fault-tolerant workloads

Spot VMs are the latest version of preemptible VMs. New and existing preemptible VMs continue to be supported, and preemptible VMs use the same pricing model as Spot VMs. However, Spot VMs provide new features that preemptible VMs do not support. For example, preemptible VMs can only run for up to 24 hours at a time, but Spot VMs do not have a maximum runtime unless you limit the runtime. Learn more about Spot VMs and how to create Spot VMs.

There is a predefined role now: roles/container.nodeServiceAccount

Prune region and zone input variables. Add location.

Add a new variable named location and infer the region and zone from it.

This will work for my use case.
