Hi, the original docker-compose file did not work by default.
You get federation port working but no client port.

My proposal is to let federation port work as it is by default (8448) and let traefik handle client http/https traffic.

If you're installing as a system package, the system package should have set up
the systemd config, so it's more useful to give an example of running in a
virtualenv here.

... and fix a typo

Link to docker/README.md

This addresses #3224

It's much easier to build the image via docker-compose instead of an
error-prone low-level docker call.
