URL: https://github.com/apache/cloudstack/issues/7517

   Hello,
   I created a Kubernetes cluster on Cloudstack and used this guide 
(https://docs.cloudstack.apache.org/en/latest/plugins/cloudstack-kubernetes-provider.html)
 to deploy Traefik as an ingress controller. 
   1. According to the guide:
   ```On successfully deploying the yaml file, a new Public IP Address in the 
same network as the cluster will be created. It will automatically have the 
firewall and port forwarding rules configured to distribute any traffic 
**amongst the cluster worker nodes**
   ```
   However, upon inspecting the LB rules, I noticed that the **control node** 
was also added as a backend server ?

   2. Furthermore, I created and deployed a file that defines a basic 
deployment, service, and ingress. However, when I curl http://k8s.lab.com.vn/, 
the response is "404 page not found". Is there a mistake in my YAML file? 
   Thanks for your help!
