Traefik v2 docker-compose with multiple domains

I am trying to move away nginx and onto traefik. Can someone help with a simple config that allows for multiple domains like so (www.mydomain.com, blog.otherdomain.com)
as I have a vps and want to hose multiple domains with wordrpress on it correctly. I see lots of blogs on the internet but they all seem to focus on only subdomains with the same parent (www.mydomain.com, blog.mydomain.com)
If it helps I'll be using cloudflare as my dns and letsencrypt

Thanks

Sure, check simple Traefik example.

Domain doesn’t matter, Traefik will use Host() to create LetsEncrypt TLS certs.
