Kubernetes 101

It's simpler than I thought

A few weeks ago, my task as work was an interesting one: To deploy a Kubernetes cluster and write the associated tooling so that developers can deploy the code in the branches they’re working on to it, so they can test their changes.

Until that point, I’ve been wanting to learn Kubernetes because it sounded interesting (even though the name is rather problematic when you’re Greek), but I never had an opportunity because I don’t have anything that needs to be on a cluster. So, I jumped at the chance, and started reading up on it, but all the materials (including the official tutorial) seemed too verbose and poorly-structured, so I was a bit dejected.
