Ok, now that your networking is set up, you can startup Kubernetes, this is the same as the single-node case, we will use the "main" instance of the Docker daemon for the Kubernetes components.
```sh
sudo docker run --net=host -d -v /var/run/docker.sock:/var/run/docker.sock gcr.io/google_containers/hyperkube:v0.17.0 /hyperkube kubelet --api_servers=http://localhost:8080 --v=2 --address=0.0.0.0 --enable_server --hostname_override=127.0.0.1 --config=/etc/kubernetes/manifests-multi
sudo docker run --net=host -d -v /var/run/docker.sock:/var/run/docker.sock gcr.io/google_containers/hyperkube:v0.18.2 /hyperkube kubelet --api_servers=http://localhost:8080 --v=2 --address=0.0.0.0 --enable_server --hostname_override=127.0.0.1 --config=/etc/kubernetes/manifests-multi
```
### Also run the service proxy
```sh
sudo docker run -d --net=host --privileged gcr.io/google_containers/hyperkube:v0.17.0 /hyperkube proxy --master=http://127.0.0.1:8080 --v=2
sudo docker run -d --net=host --privileged gcr.io/google_containers/hyperkube:v0.18.2 /hyperkube proxy --master=http://127.0.0.1:8080 --v=2
```
### Test it out
At this point, you should have a functioning 1-node cluster. Let's test it out!

Again this is similar to the above, but the ```--api_servers``` now points to the master we set up in the beginning.

sudo docker run --net=host -d -v /var/run/docker.sock:/var/run/docker.sock gcr.io/google_containers/hyperkube:v0.17.0 /hyperkube kubelet --api_servers=http://${MASTER_IP}:8080 --v=2 --address=0.0.0.0 --enable_server --hostname_override=$(hostname -i)

#### Run the service proxy
The service proxy provides load-balancing between groups of containers defined by Kubernetes ```Services```
```sh
sudo docker run -d --net=host --privileged gcr.io/google_containers/hyperkube:v0.17.0 /hyperkube proxy --master=http://${MASTER_IP}:8080 --v=2

This actually runs the kubelet, which in turn runs a [pod](http://docs.k8s.io/pods.md) that contains the other master components.

### Step Three: Run the service proxy
*Note, this could be combined with master above, but it requires --privileged for iptables manipulation*
```sh
docker run -d --net=host --privileged gcr.io/google_containers/hyperkube:v0.17.0 /hyperkube proxy --master=http://127.0.0.1:8080 --v=2

### Test it out
At this point you should have a running kubernetes cluster. You can test this by downloading the kubectl
