I have a google cloud kubernetes cluster, service definition:

apiVersion: v1
kind: Service
metadata:
  creationTimestamp: 2018-05-14T18:53:57Z
  labels:
    run: sv-security
  name: sv-security
  namespace: default
  resourceVersion: "554"
  selfLink: /api/v1/namespaces/default/services/sv-security
  uid: 27e476db-57a8-11e8-9053-42010a84014c
spec:
  clusterIP: 10.47.245.44
  externalTrafficPolicy: Cluster
  ports:
  - nodePort: 32290
    port: 80
    protocol: TCP
    targetPort: 8080
  selector:
    run: sv-security
  sessionAffinity: None
  type: LoadBalancer
status:
  loadBalancer:
    ingress:
    - ip: 35.205.38.34

and I would like to have HTTPS enabled. I followed some tutorials and got the following ingress config:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-sv-security
  annotations:
    kubernetes.io/ingress.allow-http: "false"
spec:
  backend:
    serviceName: sv-security
    servicePort: 80

(tried with serivce port 32290 as well). And created it with "kubectl apply -f ingress-sv-security.yaml"

When I go to the ip address, I get "default backend - 404".

When I run "kubectl describe ing", I get:

Name:             ingress-sv-security

  Warning  Service  0s (x8 over 18m)  loadbalancer-controller  failed to identify user specified default backend, couldn't find nodeport for default/sv-security, using system default

What am I doing wrong here?
