I got my 5 node Pi cluster finished last night. Each Pi is a 8Gb Raspberry Pi 5 with a PoE hat so it is powered over Ethernet with a M.2 hat booting off a NVMe SSD drive. I have it running docker swarm and running a dotnet application I wrote years ago that is a web UI front end to a mongo database of all the billboard top 100 hits from 1946-2024. Just for giggles I did a docker service scale replicas=200 and it handled it just fine!  Next I plan to install Pi-Hole, Paperless-ngx, homebridge, and ???
