-## Getting started locally with docker
-
-This method runs a local kubernetes cluster self hosted in Docker
-itself. The Kubelet is started in a container with access to the
-Docker API. It then launches a pod of containers that comprise the
-rest of a local-only kubernetes cluster.
-
-### Pre-requisites
-
-#### With boot2docker
-- Install [boot2docker](http://boot2docker.io/) 
-```
-boot2docker up
-$(boot2docker shellinit)
-export DOCKER_HOST_IP=$(boot2docker ip 2>/dev/null)
-export KUBERNETES_MASTER=http://$DOCKER_HOST_IP:8080
-```
-
-#### With local docker daemon
-```
-export DOCKER_HOST_IP=127.0.0.1
-export KUBERNETES_MASTER=http://$DOCKER_HOST_IP:8080
-```
-
-### Build the kubernetes docker images
-
-```
-./build/make-run-images.sh 
-```
-
-### Bootstrap the cluster
-
-```
-docker run -v /var/run/docker.sock:/var/run/docker.sock kubernetes-bootstrap
-```
-
-### Build kubernetes clean
-
-```
-./build/make-client.sh
-# set $host_os and $host_arch to your local host os and architecture.
-export PATH=$(readlink -f _output/build/$host_os/$host_arch):$PATH
-```
-
-### Manage your pods
-```
-kubecfg list /pods
-kubecfg -p 8181:80 run nginx 1 kube-nginx
-kubecfg list /pods
-curl $DOCKER_HOST_IP:8181
-```
