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?

OK so apparently this is a known issue with minikube, Ingress works properly on linux only.
you need to
minikube tunnel
on windows/macOS before being able tocurl
, but still there are differences:On Windows, both
127.0.0.1
andlocalhost
redirect to the application. On macOS,127.0.0.1
andlocalhost
show an "nginX not found" message, butcurl hello-world.info
works only after changingetc/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 ?
