Why Use K3s

Perfect for Edge

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 <70MB 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 multiarch images
available for both. K3s works great on something as small as a
Raspberry Pi to an AWS a1.4xlarge 32GiB server.

How it Works

{{ .Site.Title }}

The above figure shows the difference between K3s server and K3s
agent nodes. For more information, see the architecture
documentation.

Get Started

1. Download K3s - latest release: x86_64, ARMv7, ARM64, and s390x are
supported
2. Run server

sudo k3s server &
# Kubeconfig is written to /etc/rancher/k3s/k3s.yaml
sudo k3s kubectl get node

# On a different node run the below command. 
# NODE_TOKEN comes from /var/lib/rancher/k3s/server/node-token on your server
sudo k3s agent --server https://myserver:6443 --token ${NODE_TOKEN}
