Etcd

Last weekend I moved apartments. Five Kubernetes nodes, a NAS, and a switch came with me. By the time I was done unpacking boxes, the cluster was already back online — and I barely had to touch the network configuration to make it happen. That wasn’t luck. Months ago, when I first built this cluster, I already knew a move was on the table at some point — nothing concrete, just the normal background awareness that apartments don’t last forever. So I made a deliberate call: route the whole cluster over Tailscale IPs instead of local network addresses. I figured if the day ever came, I didn’t want to be reconfiguring DHCP reservations and static routes while also carrying boxes down three flights of stairs. ...

I wasn’t doing anything dramatic. No major deployment. No risky configuration change. I was trying to add a NAS to my homelab. New hardware means more devices, more devices means more outlets, more outlets means buying a power strip. What nobody tells you when you start this journey is that cable management becomes its own project the moment hardware starts multiplying. I ran out of space on my existing surge protector so I needed to plug the new one in somewhere close to the router, close to the switch, close to everything. ...
