Ingress not working from official kubernetes tutorial-CodePudding

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

Started up minikube
enabled the ingress add-on
created and exposed the deployment
I am able to curl after minikube service web --url:

    Hello, world!
    Version: 1.0.0
    Hostname: web-79d88c97d6-8z8tc

I created an 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. However, after creating the ingress with the below yaml, and 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? Below my Ingress yaml.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
  rules:
    - host: hello-world.info
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: web
                port:
                  number: 8080

CodePudding user response：

check your service port section with the port in your deployment, I'm sure you messed something there.

CodePudding user response：

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
