Uncloud - Tool for deploying containerised apps across servers without k8s

Having spent most of my career in kubernetes (usually managed by cloud), I always wonder when I see things like this, what is the use case or benefit of not having a control plane?

To me, the control plane is the primary feature of kubernetes and one I would not want to go without.

I know this describes operational overhead as a reason, but how it relates to the control plane is not clear to me. even managing a few hundred nodes and maybe 10,000 containers, relatively small - I update once a year and the managed cluster updates machine images and versions automatically. Are people trying to self host kubernetes for production cases, and that’s where this pain comes from?

Sorry if it is a rude question.

Try it on bare metal where you're managing the distributed storage and the hardware and the network and the upgrades too :)
