title: GKE Kubernetes Ingress is not using annotated reserved static IP even tho it has been created
body: <p>I have created a new reserved static IP in my GCP.
  See the screenshot marker <strong>1.</strong>

  However my ingress resource is still using the generated ip (screenshot marker <strong>2.</strong>)</p>
  
  <p>In the Ingress' YAML file you can see I annotated the static-ip name.</p>

  <p>That's why I am confused why it is not assigning it to the Ingress resource as expected.</p>
