Access the web frontend in a browser using the frontend's EXTERNAL_IP.

kubectl get service frontend-external | awk '{print $4}'

Example output - do not copy

EXTERNAL-IP
<your-ip>

Note- you may see <pending> while your cloud provider provisions the load balancer. If this happens, wait a few minutes and re-run the command.
