Updating The Raspberry Pi Cluster

Updating The Raspberry Pi Cluster

Hullo MicroK8s!

Awhile back the Raspberry Pi cluster was born. At the time, the best thing to run seemed to be Rancher Labs K3s. But soon after I installed K3s, Rancher released a new version and with this new version a lot of things changed, and what I had installed was deprecated. I could no longer update packages. Argh!

So …. I recently reinstalled the entire cluster using MicroK8s. I really like this version of K8s and I am having a lot of fun playing around with it. Currently trying to get an ELK stack to work, which has been challenging and frustrating. I am getting a huge kick out of the dashboard. How cool is this?

32 CPU’s, almost 600 GB of RAM from 8 nodes. Here are the nodes in the cluster and the portainer.io dashboard, which was really easy to install, it was a simple command to enable it as a plugin.

I’ll try and post an update when I get ELK configured. Stay tuned!
