I've created a Cookieplone project from scratch
When asked for the Project URL (without protocol):
I put {mysite}.com
Everything deploys to {mysite}.com but, out of the box, the traefik rules don't seem to account for www.{mysite}.com
For now, I've solved it with Cloudflare by using a redirect that redirects www.* to the domain root.
However, there will be scenarios where I will want to do all of this with traefik.
