K3s Has a Free Lightweight Kubernetes That Runs on a Raspberry Pi

Kubernetes needs 4GB RAM minimum. K3s runs a full Kubernetes cluster in 512MB — certified by CNCF, production-ready, and packaged as a single 70MB binary. What K3s Removes K3s strips Kubernetes of components most people do not need: Legacy cloud provider plugins Non-default storage drivers Docker dependency (uses containerd) Heavy alpha/experimental features What remains is 100% Kubernetes API compatible — your kubectl commands, Helm charts, and manifests work unchanged.
