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.

You can migrate VMs live between hosts (it's a bit more work if you pick libvirt, but the overhead/features or proxmox are sometimes overkill, libvirt is a bit more barebones, each has its uses), have a cluster-wide L2 network, use a machine as backup storage for others... use VM snapshots for rollback, etc. Regardless of containerization/orchestration below that, a full hypervisor is still nice to have.
I deploy my services directly to the VM or as podman containers in said VMs. I use ansible for all automation/provisioning (though there are still a few basic provisioning/management to bootstrap new VMs, if it works it works)
