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 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
