Libreoffice Collabora with Traefik / Docker compose (only part with Libreoffice, with `network1` as external network)

docker-compose_libreoffice.yml

  libreoffice:
    image: libreoffice/online:master
    environment:
      - "domain=nextcloud\\.example\\.com"
      - "SLEEPFORDEBUGGER=0"
      - "username=user"
      - "password=actualgoodpassword"
      - "extra_params=--o:ssl.enable=false --o:ssl.termination=true"
    networks:
      network1:
    cap_add:
      - MKNOD
    ports:
      - "9980:9980"
    restart:
      unless-stopped
    labels:
      - "traefik.enable=true"
      - "traefik.port=9980"
      - "traefik.http.routers.libreoffice.rule=Host(`libreoffice.example.com`)"
      - "traefik.http.routers.libreoffice.entrypoints=websecure"
      - "traefik.http.routers.libreoffice.tls.certresolver=myhttpchallenge"
      - "traefik.docker.network=network1"

ssl is disabled for Libreoffice, as Traefik is taking care of the certificate
