Last thing I need is Kubernetes at home
I am quite happy even without Docker, but I can see the appeal in some cases.
All my "smart home" stuff needs is mosquitto on a OpenWrt router and bunch of cgi-bin scripts that can run anywhere. I already went through a phase of setting up tons of services which ended up being turned off when something changed in my life (moving, replacing equipment etc.) never to be resurrected as I couldn't be bothered to redo it without the novelty effect, so I learned from that.
Since I've migrated our company to Kubernetes, I almost stopped to worry about anything. It just works. Had much more troubles running it with spaghetti of docker containers and host-installed software on multiple servers, that setup definitely breaks like every week or every month. With Kubernetes I just press "update cluster" in some saturday evening once or twice a year and that's about it, pretty smooth sailing.
