So I have rebuilt my Production rack with very little in terms of an actual software plan.
I host mostly docker contained services (Forgejo, Ghost Blog, OpenWebUI, Outline) and I was previously hosting each one in their own Ubuntu Server VM on Proxmox thus defeating the purpose.
So I was going to run a VM on each of these Thinkcentres that worked as a Kubernetes Cluster and then ran everything on that. But that also feels silly since these PCs are already Clustered through Proxmox 9.
I was thinking about using LXC but part of the point of the Kubernetes cluster was to learn a new skill that might be useful in my career and I don't know how this will work with Cloudflared Tunnels which is my preferred means of exposing services to the internet.
I'm willing to take a class or follow a whole bunch of "how-to" videos, but I'm a little frazzled on my options. Any suggestions are welcome.
OP, If you dont have a proxmox vm template ready to go, here is a great starting place using cloudinit:

You can use this with the proxmox gui cloudinit config as well to add your ssh key to each vm/etc.
