k3s section​

k3s logo

All k3s configuration files and components.

k3s a lightweight Kubernetes by Rancher.
Easy to install, half the memory, all in a binary of less than 100 MB.

Simple but powerful “batteries-included” features have been added, such as: a local storage provider, a service load balancer, a Helm controller, and the Traefik ingress controller.

External dependencies have been minimized (just a modern kernel and cgroup mounts needed).

k3s packages the required dependencies, including:

  • containerd by default (instead of Docker container runtime)
  • Flannel
  • CoreDNS
  • CNI
  • Host utilities (iptables, socat, etc)
  • Ingress controller (traefik)
  • Embedded service loadbalancer
  • Embedded network policy controller

Ansible section​
