Kubernetes cluster on a bunch of Raspberry Pis, previously known as fruitsap.
This repository is inspired by onedr0p's cluster-template, but shaped for Raspberry Pis and Single-board computers.
| Name | Model | Storage | Role |
|---|---|---|---|
| pi0 | VM 4cpu - 8GB | 64GB | Master |
| pi1 | RPI4-MODBP-8GB | 64GB (USB) | Master |
| pi2 | RPI4-MODBP-8GB | 64GB (USB) | Master |
| pi3 | RPI4-MODBP-8GB | 64GB (USB) | Worker |
| pi4 | RPI4-MODBP-8GB | 64GB (USB) | Worker |
| turing-1 | CM4108032 | 32GB (eMMC) | Worker |
| turing-2 | CM4108032 | 32GB (eMMC) | Worker |
| turing-3 | Turing RK1 - 32GB | 1024GB (NVME) | Worker |
| turing-4 | Turing RK1 - 32GB | 1024GB (NVME) | Worker |
- This template is heavily invested in SBC hardware, so it might not work for all. The takeaways of this cluster are:
- Raspberry Pi 4
- Raspberry Pi CM4
- Turing Pi 2 cluster board
- Turing Pi RK1
-
Since Turing Pi RK1 only supports Ubuntu 22.04 LTS Server custom image, this cluster will use Ubuntu as the host OS.
-
Some useful features of this cluster template are:
- flux - GitOps platform
- cilium - Kubernetes CNI
- cert-manager - Certificates management
- cloudflared - Load balancer
- traefik - Ingress Controller
- ingress-nginx - Ingress Controller

k3s is also opinionated. I'm using Lens from Mirantis so this would help with metrics and monitoring.
