I mean, I've built a Kubernetes-y thing for my own needs, mostly "scheduling" LXC and FreeBSD Jails, and it needs hella less than 256MB of RAM and it's around 20MBs. Maybe I should clean the code and publish it.

That's literally not Kubernetes, though. Does it support custom resource definitions? Services? Deployments? ConfigMaps? Multiple containers on a single host, i.e. Pods?

Your project does sound very cool but I don't think provides a fair basis of comparison re: size and RAM usage.

very good question! source definition -> no. services -> yes. deployments -> yes. configmaps -> no. multiple containers on single host -> yes. I should add the most common features I think. I also haven't integrated it with any reverse-proxy service yet, but will try that too.

The site has been updated to reflect that the nodes only need 512MB of RAM to run K3s _and Kubernetes workloads_. K3s itself doesn't consume 512MB of RAM.
