Not really. Unless you haven't tried it recently, there are many great options. Kubeadm is painless for simple clusters, and kubespray is easy if you know ansible. Of course, both assume some level of sysadmin experience, since it's a tool to manage large clusters.

Yes, took about a week to figure that one out. Most of the tutorials are always out of date.
