Special notes for your reviewer:
We consider that the better way to achieve this is through a configuration file, but currently this solution meets our needs so it's useful. We use this post-install hook in combination with Cluster Autoscaler and Vertical Pod Autoscaler, so this components are responsible for not schedule the pods in other zones after killing them for some reason (e.g. after VPA assigns new requests and limits values).
