A CNCF Sandbox 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.

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.
