Kube is trivial to run. You hit a few switches on GKE/EKS and then a few simple configs. It doesn't take very many engineer hours to run. Infrastructure these days is trivial to operate. As an example, I run a datacenter cluster myself for a micro-SaaS in the process of SOC2 Type 2 compliance. The infra itself is pretty reliable. I had to run some power-kill sims before I traveled and it came back A+. With GKE/EKS this is even easier.

Over the years of running these I think the key is to keep the cluster config manual and then you just deploy your YAMLs from a repo with hydration of secrets or whatever.
