If you only limit yourself to a subset of kubernetes's features, it's actually really great for small operations. I run a small cluster for my side projects consisting of 3 nodes. 1 node is dedicated to run database containers and control plane node (it's also a worker node but strictly for database statefulsets only), and the other 2 as worker nodes, but one of them also run an NFS server that mounted as persistent volumes so every worker nodes can have access to it. Self-healing? Internet-scale? I have on interest for them on my small cluster. I just want my apps to not go down while I'm updating them without writing complicated blue-green deployment scripts, ability to move around pods to other nodes when one got overloaded, and ability to add or remove nodes when needed without starting again from scratch. I basically treat it like docker-compose on steroid. So far it works really well.
