+   Observations:
+
+   -  If you are not using floating IPs in your Kubernetes deployment and directly attaching
+      a public IP address (i.e. by using your public provider network) to your K8S Node
+      VMs' network interface, then the output of 'kubectl -n onap get services | grep "portal-app"'
+      will show your public IP instead of the private network's IP. Therefore,
+      you can grab this public IP directly (as compared to trying to find the floating
+      IP first) and map this IP in /etc/hosts.
