kubernetes is NOT easy to setup in a secure way. I am part of several k8s SIG and we have been discussing these issues for a while now. e. g. https://github.com/kubernetes/kubernetes/issues/27343

there are tons of these niggling issues that are cropping up.

the complexity of using k8s goes up exponentially every day. I have bo doubt it is a great piece of tech.. but at this point, it seems tailor made for consulting.
