Type 2 hypervisors and Kubernetes? (alien.top)

Hey all!

I bought an e2695 v4 xeon system with the intention of learning kubernetes since my college professor who thought it was subbed at the last minute and didn't really teach it and we kind of just glazed over it. I never got around to it and my partner wanted a better PC to play Valheim so I stuck an RX580 in it and installed Ubuntu. They're not computer savvy and the 5 min boot time might be confusing to them already so I didn't want to throw grub into the mix. Can I still effectively run kubernetes through a type 2 hypervisor like virtualbox effectively for really basic spring framework services? One down side is I only have 16gb of ram in this unit since it was mostly a budget build with junk I had lying around.

I’ve run Kubernetes training sessions where all of the trainees had Windows laptops with VMware Workstation. I used K3S on K3OS as the guest OS at the time, and built a cluster of 3 Kubernetes servers with 2 CPUs and 2GB of RAM each, that ran a few basic workloads. I don’t see why you couldn’t do something similar on Ubuntu with VirtualBox as the vm host.

A simpler alternative might be to use microk8s or minikube on Ubuntu.
