To validate that your node(s) have been added, run:
```shell
kubectl get nodes
```
That should show something like:
```shell

10.240.99.26 kubernetes.io/hostname=10.240.99.26 Ready
127.0.0.1 kubernetes.io/hostname=127.0.0.1 Ready
```
If the status of any node is `Unknown` or `NotReady` your cluster is broken, double check that all containers are running properly, and if all else fails, contact us on [Slack](../../troubleshooting.html#slack).
### Run an application
```shell
kubectl -s http://localhost:8080 run nginx --image=nginx --port=80
```
now run `docker ps` you should see nginx running. You may need to wait a few minutes for the image to get pulled.
### Expose it as a service
```shell
kubectl expose rc nginx --port=80
```
Run the following command to obtain the IP of this service we just created. There are two IPs, the first one is internal (CLUSTER_IP), and the second one is the external load-balanced IP.
```shell
kubectl get svc nginx
```
Alternatively, you can obtain only the first IP (CLUSTER_IP) by running:
```shell
kubectl get svc nginx --template={{.spec.clusterIP}}
```
Hit the webserver with the first IP (CLUSTER_IP):
```shell
curl <insert-cluster-ip-here>
```
Note that you will need run this curl command on your boot2docker VM if you are running on OS X.

Now try to scale up the nginx you created before:
```shell
kubectl scale rc nginx --replicas=3
```
And list the pods
```shell
kubectl get pods
```
You should see pods landing on the newly added machine.
