it seems like small clusters are not economical with vanilla kube. (I say this having frequently tried and failed to do this, but not having done napkin math on system pod budgets to prove it to myself generally). and this gets worse once you try to install any kind of plugins or monitoring tools.
I really wonder if there's a hole in the market for 'manage 5-10 containers with ingress on one or two smallish nodes'. Or if there's a hard core of users of alternatives like swarm mode. this guy https://mrkaran.dev/posts/home-server-nomad/ evolved his home lab from kube to nomad to terraformed pure docker over 3 years.
