K3s: Kubernetes at the Edge

K3s is a CNCF sandbox project that delivers a lightweight yet powerful certified Kubernetes distribution. When used with Rancher, K3s is ideal for running production workloads across resource-restrained, remote locations or on IoT devices.


Perfect for Edge

With Rancher, K3s users can manage 1000's of edge-based clusters using our GitOps-driven Continuous Delivery capability.

A CNCF Sandbox Project

K3s was originally a Rancher Labs project. In June 2020, K3s was donated to the CNCF as a testament to the company’s commitment to the open source community. SUSE is now a major contributor to the project.

Simplified and Secure

K3s is packaged as a single < 40MB binary that reduces the dependencies and steps needed to install, run and auto-update a production Kubernetes cluster.

Optimized for ARM

Both ARM64 and ARMv7 are supported with binaries and multi arch images available for both. K3s works great from something as small as Raspberry Pi to an AWS a1.4x large 32gb server.
