Summary
In this detailed guide, I show how to convert a compact mini PC, into a Kubernetes cluster. I use Proxmox to manage the entire cluster. I add a virtual machine to be a Kubernetes worker node using Ubuntu Server as the base operating system. By installing K3S, a lightweight version of Kubernetes, I add third node in my existing K8S cluster. Possibilities after building this system are endless, from hosting websites to running databases. The 3 mini PCs from my cluster have a total of 24 threads and 48 gb of RAM as well as NVME storage while having under 50W power consumption.
