K3S is a highly available, certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances.

Simplified & Secure

K3S is packaged as a single <50MB 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 work great from something as small as a Raspberry Pi to an AWS a1.4xlarge 32GiB server.
