This page describes how to run Kubernetes on top of Clear Containers 2.1

Kubernetes

Kubernetes is a Google project and the dominant container orchestration engine.

Kubernetes clusters run containers pods. Inside a pod, all containers share the pod resources (networking, storage, etc...) and all pods within a cluster have their own IP address.

By default Kubernetes runs the full Docker stack to start pods and containers within a pod. Rkt is an alternative container runtime for Kubernetes.
