I also ran a single instance k3s node on my personal $8/mo 3gb vps, and it took up around 400MB. Ran some workloads, a postgres operator. Ingreds via traefik on the node. I think my overhead was like $1.20/mo. Did I have fancy HA? No. But it was an easy way to manage workloads & learn skills. Works fine.
