K3s is a fully conformant, production-ready lightweight Kubernetes distribution packaged as a single binary under 100MB. It bundles containerd, Flannel CNI, CoreDNS, Traefik ingress, and an embedded SQLite datastore (with etcd/MySQL/Postgres options) into an easy-to-install cluster for edge, IoT, CI, and ARM environments.

Use cases

• run a lightweight kubernetes cluster on a raspberry pi
• set up kubernetes for edge or IoT devices
• spin up a local k8s cluster for development or CI
• deploy kubernetes in air-gapped or resource-constrained environments
• embed kubernetes into an appliance or product
• create a homelab kubernetes cluster with a single command
• run a highly available kubernetes control plane without etcd complexity

When to choose

• you need a fast, simple Kubernetes install on ARM, edge, or low-resource hardware
• you want a batteries-included cluster with CNI, DNS, ingress, and storage out of the box
• you need a fully CNCF-conformant Kubernetes with minimal OS dependencies
• you want HA control plane options with sqlite, etcd, MySQL, or Postgres backends

When to avoid

• you need full upstream Kubernetes with every component individually configurable
• you run large multi-tenant clusters where a full distro like kubeadm or managed EKS/GKE fits better
• you require Windows nodes or non-Linux worker support
• you need deep customization of bundled components like Flannel or Traefik
