# Self-Hosted Kubernetes
The self-hosted Kubernetes example provisions a 3 node "self-hosted" Kubernetes v1.4.0 cluster. On-host kubelets wait for an apiserver to become reachable, then yield to kubelet pods scheduled via daemonset. [bootkube](https://github.com/kubernetes-incubator/bootkube) is run on any controller to bootstrap a temporary apiserver which schedules control plane components as pods before exiting. An etcd cluster backs Kubernetes and coordinates CoreOS auto-updates (enabled for disk installs).
