问题
I am trying to host my first dotnet core application locally on Kubernetes.
Everything is working fine but when I am trying to create service using z_service.yml file it doesn't expose port 8099 for accessing it externally in browser.
$> kubectl apply -f .\z_service.yml
service/amazing-app-service created
However if I run $> kubectl port-forward amazing-app 8099:80 command then it works and I can access the web application in browser with http://localhost:8099/
this is how services dashboard looks like
and the services status
Am I missing any configuration here?

As I see it's NodePort for your service amazing-app-service. When you want to expose the service to the Internet. You should use the LoadBalancer type for the service. Just like:
type: LoadBalancer

In Kubernetes, a service is an abstract layer that binds pods via the local network. If you need external access to your application one of the best ways is to use an ingress object.

Why do you have 9999 when your container is listening on 80. Make correction to your service.yaml and then try this in your browser http://localhost:30446
