# Kubernetes
The Kubernetes example provisions a 3 node Kubernetes v1.8.1 cluster. [bootkube](https://github.com/kubernetes-incubator/bootkube) is run once on a controller node to bootstrap Kubernetes control plane components as pods before exiting. An etcd3 cluster across controllers is used to back Kubernetes.

# Kubernetes
The Kubernetes example shows how to use Matchbox to network boot and provision a 3 node Kubernetes v1.8.1 cluster. This example uses [Terraform](https://www.terraform.io/intro/index.html) and a module provided by [Typhoon](https://github.com/poseidon/typhoon) to describe cluster resources. [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube) is run once to bootstrap the Kubernetes control plane.
