K3s and MicroK8s: Lightweight Kubernetes for Edge and IoT Applications
summary
Compares MicroK8s and K3s by concrete numbers and tradeoffs: MicroK8s installs via snap and promises 192 MB binary with automatic refresh and modular add-ons, K3s ships as a <100 MB binary and defaults to SQLite for a tiny control plane but needs etcd for HA; both run on 512 MB-class devices, support ARM/Raspberry Pi, offer quick single-command installs, and show real production use cases (smart cities, wind farms) rather than abstract benefits.
