When you say K8s is lightweight, I presume you're purely talking about GKE deployments, and not on-prem or alternate cloud deployments? My experience of K8s so far is that GKE is happy path and most of the demonstrations/documentation is focused on that use case. When you step off that path, you can either go for something scripted which does a lot of things in the background, or what seems like quite an involved manual setup (etcd, controller node setup, Certificate setup, networking etc)
