title: IP whitelisting in google container engine with ingress not working
body: <p>I am trying to whitelist IPs that can access my application. I created http-balancer by following this tutorial. <a href="https://cloud.google.com/kubernetes-engine/docs/tutorials/http-balancer" rel="nofollow noreferrer">https://cloud.google.com/kubernetes-engine/docs/tutorials/http-balancer</a></p>
  
  <p>After creating the service with <code>NodePort</code> I created an <code>ingress.yaml</code> file that looks like the one below. I have created a global static ip and setup a domain name.</p>
  
  <pre><code>apiVersion: extensions/v1beta1
  kind: Ingress
  metadata:
    name: nginx-ingress
    annotations:
      kubernetes.io/ingress.global-static-ip-name: &lt;global-static-ip&gt;
  spec:
    rules:
    - host: &lt;domain_name&gt;
    - http:
        paths:
        - path: /*
          backend:
              serviceName: nginx
              servicePort: 80
  </code></pre>
  
  <p>This above yaml file works fine and I am able to access the "Welcome to Nginx" page. </p>
  
  <p>But when I add the IPs to be whitelisted it does not seem to work and still allows other IPs that are not whitelisted.</p>
  
  <pre><code>apiVersion: extensions/v1beta1
  kind: Ingress
  metadata:
    name: nginx-ingress
    annotations:
      kubernetes.io/ingress.global-static-ip-name: &lt;global-static-ip&gt;
      ingress.kubernetes.io/whitelist-source-range: "xx.xx.xx.xxx/32"
  spec:
    rules:
    - host: &lt;domain_name&gt;
    - http:
        paths:
        - path: /*
          backend:
              serviceName: nginx
              servicePort: 80
  </code></pre>
