I actually have the same setup and it's working perfectly fine, even with my IPv4+6 specific address only config + lots of file-based configuration. I absolutely recommend using the TLS challenge with Let's Encrypt.

No problems with Docker (Compose) networks either, but I'm not using it with GitLab because I have enough IPs.

The biggest problem I see is the accumulation of certificates that will all be kept up-to-date, whether in use or not.

I also have a working system that I found very easy (for me) to setup.

Recently it all came crashing down when an old domain I had expired and I was no longer able to update the DNS in Digital Ocean. The one - unused - domain failing stopped Traefik renewing all my certificates. But I'm also on 1.7 still and really should update to 2.x

This type of configuration is _much_ more verbose on 2.x, especially if you want automatic HTTP→HTTPS redirects.

Also, Traefik 2.x still does not clean up the certificate store automatically.
