Chapter 8. Checking service access from the frontend

Procedure

  1. Get the URL details:

    $ kubectl get service hello-world-frontend -o jsonpath='{.status.loadBalancer.ingress[0].ip}'

    Use the output IP address to construct the <frontend-url>:

    <cluster-ip-address>:8080/
  2. Navigate to the <frontend-url> value in your browser and click Say hello. You see a message similar to the following:

    Hi, <name>. I am Mathematical Machine (backend-77f8f45fc8-mnrdp).

    If you click Say hello again, a different backend process responds showing how Application Interconnect balances the requests.

This shows how the frontend calls the backend over the service network from an OpenShift cluster.
