You can actually use Traefik to do something similar using its Docker service discovery. Instead of being a SOCKS proxy, Traefik is a reverse proxy, and you can combine with `lvh.me` which resolves all subdomains to localhost. I don't use this technique any more, but a functional example command can be seen here: https://github.com/CGamesPlay/dotfiles/blob/c49e2b4ddd0fe591...
