## Services on Nodes
In this section, you will see which nodes are running which services.
For each worker, `worker-0`, `worker-1`, and `worker-2`, find out which service
it is using. It will list `busy-box`, `nginx`, or `kube-dns` or a combination
of those under `Non-terminated Pod` list:
```
kubectl describe nodes worker-0
```
> output
```
