Which k8s distribution are you running? I've considered running k3s/typhoon in the past, but never had a requirement for more than one host. Plus managing stateful infra on k8s feels like a full-time job.
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.
