Today, I'll show you how to integrate OnlyOffice into your Seafile instance. The advantages are enormous! With this add-on, you can easily edit Office formats directly on the server and collaborate on files at the same time.

Prepare the Environment

you need to create a new docker compose with the following content:

services:
  onlyoffice:
    image: ${ONLYOFFICE_IMAGE:-onlyoffice/documentserver:8.1.0.1}
    restart: unless-stopped
    container_name: seafile-onlyoffice
    environment:
      #- DB_TYPE=${DB_TYPE:-mariadb}
      #- DB_HOST=${SEAFILE_MYSQL_DB_HOST:-db}
      #- DB_USER=${SEAFILE_MYSQL_DB_USER:-seafile}
      #- DB_PWD=${SEAFILE_MYSQL_DB_PASSWORD:?Variable is not set or empty}
      - JWT_ENABLED=true
      - JWT_SECRET=${ONLYOFFICE_JWT_SECRET:?Variable is not set or empty}
    volumes:
      - ${ONLYOFFICE_VOLUME:-/opt/onlyoffice}/logs:/var/log/onlyoffice
      - ${ONLYOFFICE_VOLUME:-/opt/onlyoffice}/data:/var/www/onlyoffice/Data
      - ${ONLYOFFICE_VOLUME:-/opt/onlyoffice}/lib:/var/lib/onlyoffice
    labels:
     - "traefik.enable=true"
     - "traefik.http.routers.ooffice.tls.certresolver=LEwillifixnet"
     - "traefik.http.routers.ooffice.tls=true"
     - "traefik.http.routers.ooffice.rule=Host(`${SEAFILE_SERVER_HOSTNAME}`) && PathPrefix(`/onlyofficeds`)"
     - "traefik.http.routers.ooffice.entrypoints=websecure"
     - "traefik.http.routers.ooffice.service=ooffice"
     - "traefik.http.services.ooffice.loadbalancer.server.port=80"
     - "traefik.http.middlewares.oo-strippath.stripprefix.prefixes=/onlyofficeds"
     - "traefik.http.middlewares.ooffice-headers.headers.customrequestheaders.X-Forwarded-Proto=https"
     - "traefik.http.middlewares.ooffice-headers.headers.customrequestheaders.X-Forwarded-Host=${SEAFILE_SERVER_HOSTNAME}/onlyofficeds"
     - "traefik.http.middlewares.ooffice-rewrite.replacepathregex.regex=^/onlyofficeds/(.*)"
     - "traefik.http.middlewares.ooffice-rewrite.replacepathregex.replacement=/$$1"
     - "traefik.http.routers.ooffice.middlewares=oo-strippath,ooffice-headers,ooffice-rewrite"
    networks:
      - seafile-net
      - public

networks:
  seafile-net:
    name: seafile-net
  public:
    external: true
    name: public

in the existing seafile .env add onlyoffice.yml to the COMPOSE-FILE Variable

COMPOSE-FILE='seafile-server.yml,seadoc.yml,onlyoffice.yml'

add also the following Variables to the .env:

ONLYOFFICE_IMAGE=onlyoffice/documentserver:8.1.0.1
ONLYOFFICE_VOLUME=/opt/onlyoffice
ONLYOFFICE_PORT=6233
ONLYOFFICE_JWT_SECRET=<my secret jwt>

last you must configure your seahub_settings.py (seafile-data/seafile/conf)

add the following

ENABLE_ONLYOFFICE = True
VERIFY_ONLYOFFICE_CERTIFICATE = True
ONLYOFFICE_APIJS_URL = 'https://seafile.willifix.net/onlyofficeds/web-apps/apps/api/documents/api.js'
ONLYOFFICE_FILE_EXTENSION = ('doc','docx','ppt','pptx','xls','xlsx','odt','fodt','odp','fodp','ods','fods')
ONLYOFFICE_EDIT_FILE_EXTENSION = ('docx','pptx','xlsx')
ONLYOFFICE_JWT_SECRET = '<my secret jwt>'

now restart your seafile instance and see how nice a seafile with OnlyOffice is
