I have a custom kubernetes cluster on a serve with public IP and DNS pointing to it (also wildcard). Gitlab was configured with the cluster following this guide: https://gitlab.touch4it.com/help/user/project/clusters/index#add-existing-kubernetes-cluster

However, after installing Ingress, the ingress endpoint is never detected:

I tried patching the object in k8s, like so

externalIPs: (was empty)
 - 1.2.3.4
externalTrafficPolicy: local (was cluster)

I suspect that the problem is empty ingress (scroll to the end) object then calling:

# kubectl get service ingress-nginx-ingress-controller -n gitlab-managed-apps -o yaml
apiVersion: v1
kind: Service
metadata:
  creationTimestamp: "2019-11-20T08:57:18Z"
  labels:
    app: nginx-ingress
    chart: nginx-ingress-1.22.1
    component: controller
    heritage: Tiller
    release: ingress
  name: ingress-nginx-ingress-controller
  namespace: gitlab-managed-apps
  resourceVersion: "3940"
  selfLink: /api/v1/namespaces/gitlab-managed-apps/services/ingress-nginx-ingress-controller

spec:
  clusterIP: 10.107.35.248
  externalIPs:
  - 1.2.3.4 # (public IP)
  externalTrafficPolicy: Local
  healthCheckNodePort: 30737
  ports:
  - name: http
    nodePort: 31972
    port: 80
    protocol: TCP
    targetPort: http
  - name: https
    nodePort: 31746
    port: 443
    protocol: TCP
    targetPort: https
  selector:
    app: nginx-ingress
    component: controller
    release: ingress
  sessionAffinity: None
  type: LoadBalancer
status:
  loadBalancer: {}

But Gitlab still cant find the ingress endpoint. I tried restarting cluster and Gitlab. The network inspection in Gitlab always shows this response:

...
name    ingress
status  installed
status_reason   null
version 1.22.1
external_ip null
external_hostname   null
update_available    false
can_uninstall   false
...

Any ideas how to have a working Ingress Endpoint?
