title: Traefik and multiple domains some with letsencrypt and some from SSL provider
body: <p>I'm configuring multiple domains in docker-compose and to route traffic I would like to use Traefik. He has very nice ability to create and manage letsencrypt certificate but some of my domains have enterprise SSL certificates from ssl provider (comodo).<br><br>
  My question is it possible to configure traefik such that it will be generate, manage letsencrypt certificates and at the same time he will be handle &quot;static&quot; certificates from another providers, e.g. comodo?</p>
