Error {"message":"failure to get a peer from the ring-balancer"} using kong ingress
There could be one of many things wrong here. But essentially your ingress cannot get to your backend.
If your backend up and running?
Check backend pods are "Running"
kubectl get podsCheck backend deployment has all replicas up
kubectl get deployConnect to the app pod and run a localhost:80 request
kubectl exec -it <pod-name> sh# curl http://localhostConnect to the ingress pod and see if you can reach the service from there
kubectl exec -it <ingress-pod-name> sh# dig voting-service (can you DNS resolve it)# telnet voting-sevice 80# curl http://voting-service
This issue might shed some insights as to why you can't reach the backend service. What http error code are you seeing?
The problem is resolved after deploying services and deployments in kong namespace instead of default namespace. Now I can access the application with Kong ingress public IP.
Looks like kong ingress is not able to resolve DNS with headless DNS. We need mention FQDN in ingress yaml
