Summary

Service object is not updated from KongIngress configuration. Worked before in 0.3.0.

Kong Ingress controller version 0.4.0 (dbless)

Kubernetes version

Client Version: version.Info{Major:"1", Minor:"14", GitVersion:"v1.14.0", GitCommit:"641856db18352033a0d96dbc99153fa3b27298e5", GitTreeState:"clean", BuildDate:"2019-03-25T15:53:57Z", GoVersion:"go1.12.1", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"14", GitVersion:"v1.14.0", GitCommit:"641856db18352033a0d96dbc99153fa3b27298e5", GitTreeState:"clean", BuildDate:"2019-03-25T15:45:25Z", GoVersion:"go1.12.1", Compiler:"gc", Platform:"linux/amd64"}

What happened

The following KongIngress configuration no longer updates the related service object configuration (write_timeout, read_timeout):

apiVersion: configuration.konghq.com/v1
kind: KongIngress
metadata:
  name: itop
proxy:
  write_timeout: 240000
  read_timeout: 240000
route:
  strip_path: false
---

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: itop
spec:
  tls:
  - hosts:
    - itop.aranya.localhost
    secretName: itop-tls
  rules:
  - host: itop.aranya.localhost
    http:
      paths:
      - path: /
        backend:
          serviceName: itop
          servicePort: 80

The route object is configured correctly however (strip_path).

service route

Nothing suspicious going on in the default logs either.

Expected behavior

Service object updated with configured write_timeout and read_timeout.

This works as expected.

What you need to do is apply the configuration.konghq.com annotation on the Service resource in k8s which references the KongIngress custom resource. This is noted in the changelog.
