So I am working on upgrading my homelab setup and I have a fairly specific idea of what I'd LIKE it to do, but I'm not sure if there is an system that actually can do it.

Basically I would like to run a cluster similar to how kubernetes allows you to add and remove resources from a pool, but with the ability to run multiple docker containers, but also have an ubuntu VM, and various other flexible container like things.

I have a NAS with some arr docker containers, but as I grow the amount of containers I am more and more pushing my NAS's little arm processor.

I want to start with a NUC or two and then be able to add more resources over time as I need but keep a persistent ubuntu VM that can scale and make use of the added resources. Same thing with the docker containers (arr applications and the like).

Does anyone know of a project that can do this? I'm an electrical/computer hardware engineer so I am computer literate but my networking skills are all self taught and only so-so, so anything helps. Thanks.
