K3s

K3s is a lightweight, fully compliant Kubernetes distribution optimized for resource-constrained environments. Delivered as a single <100MB binary, it's easy to install, secure by default, and ideal for edge computing, IoT, CI/CD, development, ARM devices, and air-gapped setups. With minimal dependencies and built-in components like containerd, Flannel, CoreDNS, and Traefik, K3s simplifies Kubernetes without sacrificing capability—perfect when a full-scale K8s cluster is overkill.
