Ingress doesn't work on Google Kubernetes Engine (GKE)

Below given the config, I am trying to deploy on Google Kubernetes Engine. But after deployment, I can't access the service on the ingress external IP.

I can access the service if I do:

$ kubectl exec POD_NAME
# curl GET localhost:6078/todos

But I can't access it through ingress. GKE UI show errors like:

OR

Even though the backend pod is up and running.

I believe there is something wrong with the service.

Hard to tell without knowing what 'todo' does, but there's a few things:

  1. There's an indentation error on the Ingress definition. I'm not sure if it's typo or it didn't get applied:

    Instead, it should be something:

    apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: todo-ingress
spec:
  rules:
  - http:
      paths:
      - path: /*
        backend:
          serviceName: todo
          servicePort: 6078

  2. If you really want /* with no host then the default backend is overriding you, since it's the last rule in the nginx.conf, so you might as well configure:

    apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: todo-ingress
spec:
  backend:
    serviceName: todo
    servicePort: 6078

  3. Is your service binding to 0.0.0.0 and not 127.0.0.1. Listening to on 127.0.0.1 will cause it to serve locally in the pod but not to any service outside.
