Do you have any estimates how resource hungry k0s is? Ran few resource constrained k3s clusters, where 25% of cpu was always spent on running k3s itself.
Very similar. I guess it's really k8s (the control plane) itself that is so resource intensive. Looking with top right now kube-apiserver, kubelet, kube-controller, kine and k0s use 13.5, 12.5, 5.6, and 3.0 % CPU respectively. Obviously it fluctuates quite a bit, but seems to be around 25-30% of 1 CPU core too. Also uses about 500-600mb of memory.
So yes, it definitely takes quite a bit of resources. I'm running this on 4 CPU cores and 6 GB memory, so 25% of 1 core and some 600mb of memory still leaves plenty of resources for the services. On a more philosophical note (as was mentioned below in this thread), it is a bit wasteful perhaps.
