I'm working for a spinnaker for create a new CD pipeline.

I've deployed halyard in a docker container on my computer, and also deployed spinnaker from it to the Google Kubernetes Engine.

After all of them, I've prepared a new ingress yaml file, shown as below.

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: jenkins-cloud
  namespace: spinnaker
spec:
  rules:
  - http:
      paths:
      - path: /*
        backend:
          serviceName: spin-deck
          servicePort: 9000

After accessing the spinnaker UI via a public IP, I got an error, shown as below.

Error fetching applications. Check that your gate endpoint is accessible.

After all of them, I've checked the docs about it and I've run some commands shown as below.

I've checked the service data on my K8S cluster.

spin-deck          NodePort    10.11.245.236   <none>        9000:32111/TCP   1h
spin-gate          NodePort    10.11.251.78    <none>        8084:31686/TCP   1h

For UI

hal config security ui edit --override-base-url "http://spin-deck.spinnaker:9000"

For API

hal config security api edit --override-base-url "http://spin-gate.spinnaker:8084"

After running these commands and redeploying spinnaker, the error repeated itself.

How can I solve the problem of accessing the spinnaker gate from the UI?
