Dario Ernst 633919e97c Add docker to dump traefiks certificates to pem 
This is required since traefik sitting on HTTP is able to grab
LetsEncrypt certificates which then need to be injected into the front
container.

Single-domain traefik-certdumper for mailu

This is based on the work by Sven Dowideit on https://github.com/SvenDowideit/traefik-certdumper

Fork?

This is a slight modification that is less flexible, but is adapted to the usecase in mailu. If you wish to deploy mailu behind a traefik, you face many problems. One of these is that you need to get the certificates into mailu in a very defined manner. This will copy the certificate for the Main:-domain given in the DOMAIN-environment onto output.

If your output happens to be mailu-front-/certs, the certificate-watcher in the front-container will catch it and reload nginx. This works for mailu TLS_FLAVOR=[mail, cert]

  certdumper:
    restart: always
    image: Mailu/traefik-certdumper:$VERSION
    environment:
      - DOMAIN=$DOMAIN
    volumes:
      # your traefik data-volume is probably declared outside of the mailu composefile
      - /data/traefik:/traefik
      - $ROOT/certs/:/output/
