Minikube 仪表板入口

Question

Im trying to make an ingress for the minikube dashboard using the embedded dashboard internal service.

I enabled both ingress and dashboard minikube addons.

I also wrote this ingress YAML file:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: dashboard-ingress
  namespace: kubernetes-dashboard
spec:
  rules:
  - host: dashboard.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: kubernetes-dashboard
            port: 
              number: 80

My Ingress is being created well as u can see:

NAME                CLASS   HOSTS           ADDRESS     PORTS   AGE
dashboard-ingress   nginx   dashboard.com   localhost   80      15s

I edited my /etc/hosts to add this line: 127.0.0.1 dashboard.com .

Now im trying to access the dashboard trough dashboard.com . But it's not working.

kubectl describe ingress dashboard-ingress -n kubernetes-dashboard gives me this:

Name:             dashboard-ingress
Namespace:        kubernetes-dashboard
Address:          localhost
Default backend:  default-http-backend:80 (<error: endpoints "default-http-backend" not found>)
Rules:
  Host           Path  Backends
  ----           ----  --------
  dashboard.com  
                 /   kubernetes-dashboard:80 (172.17.0.4:9090)
Annotations:     <none>
Events:
  Type    Reason  Age                From                      Message
  ----    ------  ----               ----                      -------
  Normal  Sync    14m (x2 over 14m)  nginx-ingress-controller  Scheduled for sync

I don't really understand what <error: endpoints "default-http-backend" not found> means, but maybe my issue comes from this.

kubectl get pods -n ingress-nginx result:

NAME                                        READY   STATUS      RESTARTS   AGE

Anyone has a clue on how i can solve my problem?

(Im using minikube v1.24.0)

Regards,

Answer 1

I had similar issues with Minikube's Ingress, but I was using Windows.

After indepth search, I discovered that the problem came from Docker's driver.

I changed the driver to VirtualBox and Ingress started behaving as expected.

This entry provides further details.

Answer 2

I have also faced the same issue with minikube(v1.25.1) running in my local.

kubectl get ingress -n kubernetes-dashboard

NAME                CLASS   HOSTS           ADDRESS     PORTS   AGE
dashboard-ingress   nginx   dashboard.com   localhost   80      34m

After debug I have found this. "If you are running Minikube locally, use minikube ip to get the external IP. The IP address displayed within the ingress list will be the internal IP".

Run this command

minikube ip
XXX.XXX.64.2

add this ip in the host file,after that I am able to access dashboard.com
