Need Help: Collabora Online Integration with Seafile Pro 12 (Docker, Traefik)

Seafile Server
1

I’m trying to integrate Collabora Online with my Seafile Pro (v12) server, both running as Docker containers on the same host, behind Traefik. I followed the official documentation but I can’t get online editing to work. When I click on a .docx file, I get “Online view is not applicable to this file format”.

Here is my Collabora service in docker-compose:

  collabora:
    image: ${COLLABORA_IMAGE:-collabora/code:24.04.5.1.1}
    container_name: ${APP_NAME}-collabora
    environment:
      - domain=${SEAFILE_SERVER_HOSTNAME:?Variable is not set or empty}
      - username=${COLLABORA_USERNAME:?Variable is not set or empty}
      - password=${COLLABORA_PASSWORD:?Variable is not set or empty}
      - DONT_GEN_SSL_CERT=true
      - extra_params=--o:admin_console.enable=${COLLABORA_ENABLE_ADMIN_CONSOLE:-true}
        --o:ssl.enable=false
        --o:ssl.termination=true
        --o:remote_font_config.url=${COLLABORA_REMOTE_FONT:-}
        --o:logging.file[@enable]=${COLLABORA_ENABLE_FILE_LOGGING:-false}
        --o:logging.file.property[0]=/opt/cool/logs/coolwsd.log
    volumes:
      - "${COLLABORA_PATH:-/opt/collabora}/logs:/opt/cool/logs/" # chmod 777 needed
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.${SUBDOMAIN_NAME}-collabora.rule=Host(`${SEAFILE_SERVER_HOSTNAME}`) && PathPrefix(`/hosting/discovery`, `/lool`, `/loleaflet`, `/browser`, `/cool`)"
      - "traefik.http.routers.${SUBDOMAIN_NAME}-collabora.entrypoints=websecure"
      - "traefik.http.routers.${SUBDOMAIN_NAME}-collabora.tls=true"
      - "traefik.http.services.${SUBDOMAIN_NAME}-collabora.loadbalancer.server.port=9980"
      - "traefik.http.middlewares.${SUBDOMAIN_NAME}-collabora-stripprefix.stripprefix.prefixes=/hosting/discovery,/lool,/loleaflet,/browser"
    networks:
      - seafile-net
      - traefik-net
    cap_add:
      - MKNOD
    depends_on:
      - seafile

And here is my seahub_settings.py:

OFFICE_SERVER_TYPE = 'CollaboraOffice'
ENABLE_OFFICE_WEB_APP = True
OFFICE_WEB_APP_BASE_URL = 'https://seafile.company.com/hosting/discovery'
WOPI_ACCESS_TOKEN_EXPIRATION = 1800
OFFICE_WEB_APP_FILE_EXTENSION = ('odp', 'ods', 'odt', 'xls', 'xlsb', 'xlsm', 'xlsx', 'ppsx', 'ppt', 'pptm', 'pptx', 'doc', 'docm', 'docx')
ENABLE_OFFICE_WEB_APP_EDIT = True
OFFICE_WEB_APP_EDIT_FILE_EXTENSION = ('odp', 'ods', 'odt', 'xls', 'xlsb', 'xlsm', 'xlsx', 'ppsx', 'ppt', 'pptm', 'pptx', 'doc', 'docm', 'docx')
  • I can access https://seafile.exemple.com/hosting/discovery but the page is : Sorry, but the requested page could not be found.
  • Seafile and Collabora are on the same Docker host, and both are on the seafile-net and traefik-net networks.
  • Traefik handles HTTPS termination.
  • HTTPS is enable in my .env
  • http://collabora:9980/hosting/discovery or *http://container_name:9980/hosting/discovery don’t work : collabora ’s server IP address could not be found. I can ping container_name from the Seafile container.
  • https://seafile.company.com/hosting/discovery don’t work : Online view is not applicable to this file format

What am I missing?

  • Are my docker-compose and seahub_settings.py correct?
  • Is there something else I should check in Traefik or Collabora configuration?
  • Any advice on troubleshooting this integration?

The problem has been resolved. The issue was in the router rules declaration

  • “traefik. http.routers.${SUBDOMAIN_NAME}-collabora.rule=Host(${SEAFILE_SERVER_HOSTNAME}) && (PathPrefix(/hosting/discovery) || PathPrefix(/lool) || PathPrefix(/loleaflet) || PathPrefix(/browser) || PathPrefix(/cool))”

And not :

  • “traefik.http.routers.${SUBDOMAIN_NAME}-collabora.rule=Host(${SEAFILE_SERVER_HOSTNAME}) && PathPrefix(/hosting/discovery, /lool, /loleaflet, /browser, /cool)”
