title: Problems configuring Ingress with cookie affinity
body: <p>I was looking for how to use cookie affinity in GKE, using Ingress for that.</p>
  
  <p>I've found the following link to do it: <a href="https://cloud.google.com/kubernetes-engine/docs/how-to/configure-backend-service" rel="nofollow noreferrer">https://cloud.google.com/kubernetes-engine/docs/how-to/configure-backend-service</a></p>
  
  <p>I've created a yaml with the following:</p>
  
  <pre><code>---
  apiVersion: apps/v1
  kind: Deployment
  metadata:
    name: my-bsc-deployment
  spec:
    selector:
      matchLabels:
        purpose: bsc-config-demo
    replicas: 3
    template:
      metadata:
        labels:
          purpose: bsc-config-demo
      spec:
        containers:
        - name: hello-app-container
          image: gcr.io/google-samples/hello-app:1.0
  ---
  apiVersion: cloud.google.com/v1beta1
  kind: BackendConfig
  metadata:
    name: my-bsc-backendconfig
  spec:
    timeoutSec: 40
    connectionDraining:
      drainingTimeoutSec: 60
    sessionAffinity:
      affinityType: "GENERATED_COOKIE"
      affinityCookieTtlSec: 50

  apiVersion: v1
  kind: Service
  metadata:
    name: my-bsc-service
    labels:
      purpose: bsc-config-demo
    annotations:
      beta.cloud.google.com/backend-config: '{"ports": {"80":"my-bsc-backendconfig"}}'
  spec:
    type: NodePort
    selector:
      purpose: bsc-config-demo
    ports:
    - port: 80
      protocol: TCP
      targetPort: 8080
  ---
  apiVersion: extensions/v1beta1
  kind: Ingress
  metadata:
    name: my-bsc-ingress
  spec:
    rules:
    - http:
        paths:
        - path: /*
          backend:
            serviceName: my-bsc-service
            servicePort: 80
  ---
  </code></pre>
  
  <p>Everything seems to go well. When I inspect the created Ingress I see 2 backend services. One of them has the cookie configured, but the other doesn't.</p>
  
  <p>If I create the deployment, and from GCP's console, create the Service and Ingress, only one backend service appears.</p>
  
  <p>Somebody knows why using a yaml I get 2, but doing it from console I only get one?</p>
  
  <p>Thanks in advance </p>
