Hi, I'm kr0x7c0. My homelab started as "a couple of containers, just to try" and somehow ended up as a rack with a Proxmox cluster, a real firewall and fans added in a panic.
I write about it on my blog, mostly so I don't have to figure out the same things twice: self-hosting, Docker, Proxmox, networking, and what breaks along the way.
For weeks my Proxmox cluster had a fixed ritual: a node would vanish, I'd force it off, wait five minutes for it to cool down and turn it back on. Three or four times a week.
The problem was running Ceph on three NUCs. Here's how it ended:

Do you run Ceph in your homelab, or leave it to real servers?
