Re:Will Kubernetes Collapse Under the Weight of Its Complexity?

I'm late to this party, but I agree. We hired someone who was explicitly a "Kubernetes" expert, because we were investigating Kubernetes.
What we discovered is that this meant they understood kubectl pretty well, and could write the yaml files. He didn't understand anything under the hood, so we had to re-discover everything.
And, ultimately, if you want to get a feel for how complex k8s really is, try and use their documentation beyond the very basics. It's contradictory, incomplete, and behind by a version of two sometimes. It was fun building a set of automated interactions with kubectl and its cousins from the web documentation, only to find it doesn't work because the actual binaries expect different arguments.
Or the API libraries if you're feeling particularly brave: a set of these horribly complex, dynamically generated files. Oh, some of them will be alpha, others beta, others beta2, etc. The version depends on the function you're using. Have fun!
