Go to any Kubernetes page and it's all heavyweight "nodes" and "containers" and "tasks" and "resources" (some of which seem to have very special meanings). It's not easy to get into.

I don't think this is some oversight on behalf of the technical writers. They don't lack the ability to explain it in simple terms, they're putting up a warning sign. If you want to join Kubernetes, it's going to mean your entire way of doing things will now be the Kubernetes way, it's not just going to be a few lines of code you add to a Make file.

A lot of people are wary of these heavyweight systems, because it's going to end up a fairly hard dependency.
