Well I made Kubernetes cluster using Raspberry PIs, I largely followed the guide RasperryPI 4 Cluster
It has the following features
- 5 Raspberry Pi 4s, 4Gb RAM
- 1 DualCore x64, 16Gb RAM
- 1 DualCore x64, 4Gb RAM
- 4Tb storage distributed over the whole cluster
- ClusterCTRL, this is so power goes through the backplane rather than having 5 seperate power sources
Things that are using the cluster, well this site for one
