GKE

In my previous post, I present the easist and most secure way to get kubectl working for one project. But what about mutiple projects? Juggle mutiple projects on Google Container Engine (GKE) can be hard, especially when its configurations are admittedly quirky. This post describes the best practice, in my opinion, to keep configurations sane and easy to switch.

Problem

Suppose you have an awesome app that runs on GKE. You probably want to have two different environments staging and production, and the environments should be completely isolated. So you create two projects on GKE, awesome-app-staging and awesome-app-production, and provisioned resources for each. Now the question is how to effectively switch between the two projects on command line without repeating these commands over and over again.
