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.
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
.
