But what about mutiple projects? Juggle mutiple projects on Google Container Engine (GKE) can be hard, especially when its configurations are admittedly <a href="https://github.com/kubernetes/kubernetes/issues/20605">quirky</a>. This post describes the best practice, in my opinion, to keep configurations sane and easy to switch.</p> <h2 id="problem">Problem</h2> <p>Suppose you have an awesome app that runs on GKE. You probably want to have two different environments <code>staging</code> and <code>production</code>, and the environments should be completely isolated. So you create two projects on GKE, <code>awesome-app-staging</code> and <code>awesome-app-production</code>, and provisioned resources for each. Now the question is how to effectively switch between the two projects on command line without repeating <a href="https://github.com/kubernetes/kubernetes/issues/20605#issuecomment-218322105">these commands</a> over and over again.</p>
