To play with the service itself, find the external IP of the load balancer from the [Google Cloud Console][cloud-console] or the `gcloud` tool, and visit `http://<ip>:3000`.
To play with the service itself, find the external IP of the load balancer:

and then visit port 3000 of that IP address e.g. `http://104.154.87.59:3000`.
You may need to open the firewall for port 3000 using the [console][cloud-console] or the `gcloud` tool. The following command will allow traffic from any source to instances tagged `kubernetes-minion`:

### Step Seven: Cleanup
You should delete the service which will remove any associated resources that were created e.g. load balancers, forwarding rules and target pools. All the resources (pods, replication controllers and service) can be deleted with a single command:
```shell
$ cluster/kubectl.sh delete -f examples/guestbook-go
current-context: "kubernetes-satnam_kubernetes"
Running: cluster/../cluster/gce/../../_output/dockerized/bin/linux/amd64/kubectl delete -f examples/guestbook-go
