  MicroK8s is a small, fast, secure, single node Kubernetes that installs on
  just about any Linux box. Use it for offline development, prototyping,
  testing, or use it on a VM as a small, cheap, reliable k8s for CI/CD. It's
  also a great k8s for appliances - develop your IoT apps for k8s and deploy
  them to MicroK8s on your boxes.
