Take Kubernetes to the Edge

Optimized for edge and IoT applications, k3s is a highly available, certified Kubernetes application geared for use in unattended, remote, resource-constrained environments. K3s bundles all k8s components into combined processes and presents it all in a simple server-and-agent model that’s easy to use and fast to deploy. It’s so lightweight you could run it on a Raspberry Pi.

Why K3s and Rancher?
