Ingress not working from official kubernetes tutorial – Nginx

I am following this official k8 ingress tutorial. However I am not able to curl the minikube IP address and access the "web" application.

minikube addons enable ingress
kubectl create deployment web --image=gcr.io/google-samples/hello-app:1.0
kubectl expose deployment web --type=NodePort --port=8080
kubectl apply -f https://k8s.io/examples/service/networking/example-ingress.yaml

I’m able to curl the result of minikube service web --url

    curl http://127.0.0.1:64671 
    Hello, world!
    Version: 1.0.0
    Hostname: web-79d88c97d6-8z8tc

But not though ingress, with kubectl apply -f https://k8s.io/examples/service/networking/example-ingress.yaml

(I don’t have an external IP – just "localhost". )

NGG282 kubernetes-ingress % kubectl get ingress
NAME              CLASS   HOSTS   ADDRESS     PORTS   AGE
example-ingress   nginx   *       localhost   80      66m

This seems to be normal with minikube. Trying to curl the minikube IP:

curl $(minikube ip)
curl: (7) Failed to connect to 192.168.49.2 port 80: Operation timed out

Any help?

kubectl get deploy -n ingress-nginx -o yaml

    OK so apparently this is a known issue with minikube, Ingress works properly on linux only.

    The ingress, and ingress-dns addons are currently only supported on Linux. See #7332

    you need to minikube tunnel on windows/macOS before being able to curl, but still there are differences:

    On Windows, both 127.0.0.1 and localhost redirect to the application. On macOS, 127.0.0.1 and localhost show an "nginX not found" message, but curl hello-world.info works only after changing etc/hosts.

    You need to setup your /etc/hosts, I guess the ingress controller wait for requests with an host defined to redirect them, but it’s pretty strange that it didn’t even respond to the http request with an error.

    Could you show what these commands returns ?

    kubectl get deploy -n ingress-nginx -o yaml  # only the ports section
kubectl get svc -n ingress-nginx -o yaml
