I'm sure this has benefit to someone but it doesn't really answer my core "K8S is simple" question in my mind:
Single node proxmox VM/LXC mix homeserver. Is learning K8S worthwhile?
I can see it helping me on cloud tech (inherently multi node) yet seems like a net negative at home.
It's one of those "it's popular & I could learn that, but what is the personal payoff for me here?"
Maybe, although if you're fully happy with your current setup then probably not unless you just want to explore and learn new things.
I use kubernetes "at home" (ok, well it's an OVH server, but I use it for personal/home stuff), and I like it. I happen to run a wide variety of apps for myself and friends, already used docker, and I was somewhat reaching the limits of docker compose.
I really like the consistent ecosystem, and that k8s cleanly deals with problems like TLS termination with LE[1] and automatically updating my DNS[2]. I like that I can just write down what I want in a YAML file and don't have to mess around with docker commands or package managers or what else.
It's not for everyone, but I wouldn't say there's no value in it, especially if you're already using containers or a similar tool.
