I built a Pi‑powered Kubernetes cluster — was it worth it?

A Raspberry Pi 5 nestled in a shoebox rack, spinning its wheels with "real" Kubernetes. It sips a dainty 10W but stumbles over hiccups like ARM64 chart voids and single-lane PCIe NVMe antics. Though NVMe drives rocket from 90MB/s to 350MB/s, reeling in those image pulls, thermal throttling and x86-exclusive charts throw a wrench in the works. If silent efficiency, modularity, and a chance to roll up your sleeves matter more than sheer speed, it's a tinkerer's paradise.
