I deployed two services in a cluster in google cloud.

When I run: kubectl get services I get->

NAME           TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)          AGE

hello-java-1   NodePort    10.7.254.204   <none>        8080:31848/TCP   21m

hello-java-2   NodePort    10.7.246.52    <none>        8080:30624/TCP   19m

kubernetes     ClusterIP   10.7.240.1     <none>        443/TCP          23m

Now, I followed as per google cloud docs: Ingress and configured the fanout-ingress as:

apiVersion: extensions/v1beta1

kind: Ingress

metadata:

  name: fanout-ingress

spec:

  rules:

  - http:

      paths:

      - path: /product/*

        backend:

          serviceName: hello-java-1

          servicePort: 8080

      - path: /list/*

        backend:

          serviceName: hello-java-2

          servicePort: 8080

Now:

$kubectl get ingress fanout-ingress

NAME             HOSTS     ADDRESS         PORTS     AGE

fanout-ingress   *         35.190.55.204   80        17m

I get these results.

I checked the command: kubectl describe ingress fanout-ingress

The output is:

  *

        /product/*   hello-java-1:8080 (<none>)

        /list/*      hello-java-2:8080 (<none>)

  Normal  ADD      18m               loadbalancer-controller  default/fanout-ingress

  Normal  CREATE   17m               loadbalancer-controller  ip: 35.190.55.204

  Normal  Service  8m (x4 over 17m)  loadbalancer-controller  no user specified default backend, using system default

Now when I access http://35.190.55.204/product/home I get spring whitelabel error.. but home is defined in the application! Why this happens?

I got the issue! For the path to be /product/*, all the URL mappings of our first service Requestpath in spring application should start with /product/

ex: /product/list, /product/add, /product/delete etc

Also for Ingress path rule /list/*, all the URL mappings in our second service Requestpath in spring application should start with /list/

ex: /list/sort, /list/add, /list/delete etc
