Regular Twitch streamer, Jeff Fritz (csharpfritz) has been trying to configure a Kubernetes cluster using K3s by Rancher Labs installation on six Raspberry Pis. They hit multiple roadblocks, such as trying to set up NFS-based Persistent Volumes in the cluster shared between the nodes, and accessing the dashboard.
