As I lay the foundation for my Pi powered K3s cluster, I’ve decided that I want all four nodes to be identical. Thus, I have ordered two Raspberry Pi CM4s, each with 8GB ram and 32GB eMMC flash storage. These match the specs of two of my other CM4s already in the Turing Pi. Once installed, I plan to bring up the cluster within the next few days. I’m looking forward to configuring and learning about MetalLB, a Kubernetes-based load balancer that assigns IP addresses to services, facilitating network requests to those IPs.
