I tried k3s but wasn't happy with its resource utilisation. I settled on k0s with integrated etcd, and the crun container runtime. Additionally k0s deployments can managed with k0sctl and yaml.

I run a single intel n100 node running Fedora Core. Initially it was a lot of tinkering with IaC / yaml but once I had a working setup, I spend most of the time merging PRs from renovate from my phones GitHub app that keeps the software updated.

Some supporting benchmarks.
