I recently built a lightweight Kubernetes cluster at home using Raspberry Pi 4 devices, and I documented the entire setup process step by step.

This guide covers: Flashing Raspberry Pi OS and preparing the nodes Installing K3s for a lightweight Kubernetes deployment Setting up MetalLB for load balancing on a home network Using Tailscale to securely access the cluster remotely Bonus tips for monitoring and troubleshooting

It’s designed for DevOps engineers, homelab enthusiasts, or anyone curious about running production-like infrastructure on minimal hardware.

Would love feedback or ideas on how to improve it! Anyone else running Kubernetes at home?

What does one actually run on a home kubernetes setup like this? I have trouble imagining something that I'd need to scale horizontally at home.
