title: In GCP, how to route Custom Domain for Cloud Run to Load Balancer?
body: <p>I setup a cloud run app, I have brought a custom domain, I would like to add load balancer to it.</p>
  <p>How do I change the custom domain DNS to point to the new load balancer IP?  I have tested the IP and it works.</p>
  <p>My working load balancer IP (example only):</p>
  <pre><code>1.2.3.4:80
  </code></pre>
  <p>My working external custom domain (example only):</p>
  <pre><code>dev.mywebsite.com
  </code></pre>
  <p>Here is what I have tried, I just pasted the IP into the CNAME record and it doesn't work.  It say the website could not be reached.</p>
