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.
This is a 52pi 10 inch rack 8U
I have 4 raspberry Pi4's 4gb running with POE
Some TP-link gigabit switch with 4/poe ports
3 Thinkcentre Tiny with a ryzen 5 2400GE 32 gigs ddr4 RAM, 512 Sabrent PCIE Gem 4 NVME boot/VM drive, 512 PNY Sata SSDs for databases
I have a bigger server for AI stuff and storage. This is just Tue "production" server for my websites and Git repos
I stole the set up idea from my man Jan Wildeboer
