<p>Does anyone know if Google’s HTTPS loadbalancer is working?
I was working on setting up a NGINX ingress service but I noticed the Google Loadbalancer was automatically being setup by Kubernetes. I was getting two external IPs instead of one. So instead of setting up the NGINX load balancer I decided to use the Google service. I deleted my container cluster, created a brand new one. I started my HTTP pod and HTTP service on port 80. I then created my ingress service and L7 controller pod. Now I'm getting the following error when I review the load balancer logs: </p>

<blockquote>

<p>Probably you have one or more hanging backend services. Run <code>gcloud compute backend-services list</code> to find them and then <code>gcloud compute backend-services delete [SERVICE-NAME]</code> for each service to remove it.</p>

<pre><code>$ gcloud compute backend-services list
NAME                            BACKENDS                                                             PROTOCOL
my-hanging-service              us-central1-a/instanceGroups/gke-XXXXXXX-default-pool-XXXXXXX-grp  HTTP

$ gcloud compute backend-services delete my-hanging-service
</code></pre>
