Verification of the services deployment

Verify that the services are running properly by executing this command:

kubectl get pods -n application

The output should be similar to this, all pods should have STATUS as Running. If not then you need to look at the logs for the pods/service to determine what is wrong for example kubectl logs -n application svc/customer.
