We need to create a Blog App ingress gateway to associate our application with the Istio ingress gateway. It is necessary for configuring our application to route traffic through the Istio ingress gateway as we want to leverage Istio’s traffic management and security features.

Istio deploys the Istio ingress gateway as a part of the installation process, and it’s exposed on a load balancer by default. To determine the load balancer’s IP address and ports, you can run the following commands:

$ kubectl get svc istio-ingress -n istio-ingress
NAME           EXTERNAL-IP    PORT(S)       
istio-ingress  34.30.247.164  80:30950/TCP,443:32100/TCP

As we can see, Istio exposes various ports on your load balancer, and as our application needs to run on port 80, we can access it using http://<IngressLoadBalancerExternalIP...
