Raspberry Pi Cluster

Post by GrueMaster »

So, I have a RPI Kubernetes cluster now. Built as a learning tool for work. 4 systems, using Raspberry PI 4B 2G systems, Power Over Ethernet (POE) Hats for each, and a 5 port 1G POE switch. All cases and the rack they're going in were 3D printed over a few days on my CR-10S.

I'm still working out a cooling solution. I currently have a USB desk fan blowing over them, which keeps them at 33C, but with only passive heatsinks, they will run between 75C-79C. I need to design a housing for a 20mm fan, then come up with a power solution for the fans. I have a few ideas, though.

Once they are properly cooled, I will take them to work and start using them to develop and deploy our apps as microservices.

The red box is the cluster master, the green boxes are the slaves (or whatever is PC these days), and the black box is the 5 port POE switch. The fan is a USB powered desk fan and it keeps the entire rack cool enough.
