The Past, Present, and Future of Kubernetes on Raspberry Pi

on YouTube ↗34m

" summary

History and roadmap for running Kubernetes on Raspberry Pi with concrete recipes: a demo cluster runs k3s on Raspberry Pi 3/4 with three masters, etcd/sql (or SQLite) HA, ~500 MB control-plane footprint, and worker pods using ~50 MB each; apps deploy via OpenFaaS with GitHub Actions building multi‑arch images and Hugo, pushed over an inlets operator tunnel to an EC2 relay for a public TLS site; hardware notes cover net‑booted BitScope blade with NVMe, CM4/compute modules, power supply and fan requirements, and storage/volume options.
