It is better now with kubeadm. There are still lots of things to learn and lots of breaks which can happen but after months of learning I now have my hown cluster and it works perfectly. It mounts NFS store, also use local storage and I plan to play with OpenEBS. Nginx ingress + certbot (let's encrypt auto-renowal) works fine. Logging can be done with Fluentd and Graylog. Prometheus for performance measures. MetalLB as load-balancing replacement on L2. Calico for networking and networkPolicies. Cloud providers definitely have some added benefits, less friction. But 'do-it-yourself' is well possible as wrll and it helps you to understand more individual pieces K8S is made of and how to debug those.
