I do not have in-depth knowledge of traefik unfortunately. I tried it a while ago, but decided to switch to the setup mentioned above for the setup simplicity. For my use-case, the setup mentioned on github under "Basic usage example, using docker-compose" plus adding two lines to a docker-compose file has been enough for most of my use-cases, and never given me any trouble.

I think achieving a similar setup in traefik (e.g. https://github.com/tiangolo/blog-posts/blob/master/deploying...) would be more complicated, and I felt like I was not sure what all the labels did or how to adapt the setup.
