One thing is certain, you can’t have many raspberry pith. And if for some reason you have too many Pis, there’s no reason not to cram them all into one cool project. Today, we’re showing you some great work from Alexander Rau, a manufacturer who seems to have done just that. Rau uses his eight Raspberry Pi CM4 modules for custom power Kubernetes cluster.
Lau documented the process in a very detailed blog post, detailing the journey from concept to finished product. He knew that he wanted to use K3s, a Kubernetes distribution, and that he wanted to build a custom PCB for the project, but turning the idea into a reality proved to be a difficult but rewarding undertaking. got it.
There were some major hurdles in developing the project. First, developing a custom carrier PCB for the CM4 module was a big undertaking. We needed to provide some key functionality and the existing carrier board contained more components than the project required. I also had to build a cluster tray to house the PCB from scratch. On the software side, we had to learn how to manage the hardware. rancher (opens in new tab) Configure your system to automate using Ansible.

After months of planning and prototyping, he settled on what he calls Less-is-More Career Boards, or LiMs for short. This his PCB supports the Raspberry Pi CM4 and has Ethernet support, a microSD slot, his M.2 M key socket for SSD and much more. The cluster tray is 3D printed and supports a total of 8 cluster nodes.
As mentioned above, Rau chose to use Rancher to manage his cluster. Each Raspberry Pi CM4 module is running the latest version of her Raspberry Pi OS. This is required for cluster automation using Ansible. Rau has kindly shared many details about the software set up in the original project post.
