I had a similar experience myself with Kubernetes. The first time I tried to learn it, it was a bewildering morass of jargon—all those namespaces and containers and Pods and Deployments and Services and Ingresses just to get a simple HTTP server running! Then I read a networking textbook and everything made much more sense. The (arguably) most complicated parts of Kubernetes exist to solve networking-related problems—allowing hundreds of containers to talk to each other independently while hosted on a much smaller set of computers—so the networking textbook gave me a schema onto which I could hang all my Kubernetes factoids. Once I knew how Linux’s IP routing, iptables, and network namespaces worked, it was much easier for me to understand what exactly something like “kube-proxy” was doing. – In defense of blub studies
