Minikube expose service nginx proxy manager

Question

I'm learning and trying to setup minikube in an ubuntu server to manage and deploy applications.

I'm using nginx proxy manager application to manage the proxy's in the server.

I've followed this tutorial to setup ingress with NGINX Ingress Controller, and everyhing works fine, when I run curl *minikube_ip*:service_port I get

Hello, world!
Version: 1.0.0
Hostname: web-746c8679d4-zhtll

Now, the problem is, I'm trying to expose this to the outside world by adding a proxy host in nginx proxy manager that proxies domain_name.com to the *minikube_ip*:service_port but it just keeps giving me 504 Gateway Time-out.

here's the 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
          - path: /v2
            pathType: Prefix
            backend:
              service:
                name: web2
                port:
                  number: 8080

When I run kubectl get svc

NAME         TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE
kubernetes   ClusterIP   10.96.0.1        <none>        443/TCP          2d12h
web          NodePort    10.104.186.135   <none>        8080:31806/TCP   2d12h

In my hosts file

*minikube_ip* hello-world.info

I suspect it might be related to the minikube docker container not being in the same network as the nginx proxy manager container, but I really don't know how to solve this, help pls

Answer 1

A NodePort type service can be accessed via the IP Address of the node(s) running in your cluster. Kubernetes will route the request to the proper pod based on the IP and port provided.

If you want to use a host name defined in an Ingress resource instead of the IP Address and port, change your service to type=ClusterIP.

Try running the following command to change your service to type ClusterIP:

kubectl patch svc web -p '{"spec": {"type": "ClusterIP"}}'

Wait for an EXTERNAL-IP to be assigned to the service, you can watch using kubectl get svc --watch

Update your hosts file with the EXTERNAL-IP value instead of the minikube_ip

Finally, try visiting hello-world.info in the browser
