title: Kubernetes: multiple domain setup and loadbalancer/ingress strategy
body: <p>How is it possible to use more than one domain in the same cluster?</p>
  <p>At the moment I've running ONE cluster with <strong>one domain</strong> pointing to a hardware <code>loadbalancer</code> and <code>traefik</code> as an <code>ingress-controller</code>.</p>
  <p>Now I wanna add a second domain pointing to different workloads/services.</p>
  <p>Do I need</p>
  <ol>
  <li>a second <code>ingress-controller</code> with a second <code>LoadBalancer</code> (and pointing the second domain to that second LB)?</li>
  <li>to point the second domain to the same first <code>LoadBalancer</code> to use only one ìngress-controller`?</li>
  </ol>
  <p>I am asking, because I have troubles when pointing the second domain to the second <code>Loadbalancer</code> and pointing that one to the existing <code>ingress-controller</code> (nothing happens)
  But when I point my <strong>second domain</strong>, to the first Loadbalancer, it seems working as expected.</p>
  <p><em>(My guess is: solution &quot;2&quot;)?</em></p>
  <p>(I wanna keep one Ingress-controller, thought I need two loadbalanacers)</p>
  <p>Does this have to do with the occupied ports 443 and 80?</p>
  <p>Thank you</p>
