My Raspberry Pi Incus Cluster

4 RasPi's in a metal case

RasPi Cluster

This is my 4x Raspberry Pi 4 (8GB) Incus cluster I wrote about in my "selfhosted" page. I built it for tinkering in a nice metal case.

The cluster consists of 4x Raspberry Pi 4 with 8GB RAM and has a 500GB SSD attached to each of them. Inside the case at the bottom is a 5-port 1GBit switch which connects the Pis to the network.

Incus Container/VM Manager

The cluster runs the Incus Container/VM Manager in a cluster setup running on Raspberry Pi OS (Trixie). Incus uses the arm64 apt repository for Debian "Trixie", so I always have the most recent version of Incus running.

I update the whole cluster with Ansible. I mainly use it to learn and tinker with an Incus cluster, but the updates can be a little unstable, so I use my Proxmox Cluster for services which need to be more reliable on two x86_64 (amd64) nodes.

Best wishes,
