Kubernetes

Hi all. We're starting our move from D7 to D8, and are going to be using Docker and Kubernetes (with Jenkins) to manage and deploy our D8 environments.

Since with Docker and Kubernetes deploying as many identical nodes as you want / need is trivial, I'm looking for feedback re choosing the standard one-to-many design of Varnish and Drupal nodes (each Varnish node points at multiple Drupal backends), as opposed to a one-to-one design where each Varnish node points at a single Drupal backend.
