Deploy ONLYOFFICE Documentserver

3.0 Enterprise Edition

OnlyOffice offers real-time collaboration with office documents in your browser. As soon as you open a file from SeaTable, OnlyOffice opens in a new browser tab and allows real time collaboration. As soon as the last user exits the document by closing his browser window, the document is saved back to the SeaTable base. Access takes place via the public URL via HTTPS. So that OnlyOffice cannot be used by other systems, a shared secret in the form of a JWT key is used.

You have to decide: Collabora OR OnlyOffice

Collabora and OnlyOffice are both office editors. You have to decide which one you would like to use. You can not use both in parallel.

Use a separate host, if you expect many users

OnlyOffice can be installed on the same host as SeaTable Enterprise Edition. If OnlyOffice is used regularly and by many users, the host should be fitted with sufficient cores and RAM.

This manual assumes that SeaTable Enterprise Edition is installed and is running.


1. Change the .env file

Add onlyoffice.yml to the COMPOSE_FILE variable.

nano /opt/seatable-compose/.env

Your COMPOSE_FILE variable should look something like this:


2. Generate inital secret

Generate inital secrets and write them into your .env file.

echo -e "\n# OnlyOffice" >> /opt/seatable-compose/.env
echo "ONLYOFFICE_JWT_SECRET=$(pwgen -s 40 1)" >> /opt/seatable-compose/.env

3. Modify

Open /opt/seatable-server/seatable/conf/ with your favorite editor and add the following code block at the end of the file.

source /opt/seatable-compose/.env
echo -e "\n# onlyoffice" >> /opt/seatable-server/seatable/conf/
echo "ENABLE_ONLYOFFICE = True" >> /opt/seatable-server/seatable/conf/
echo "ONLYOFFICE_APIJS_URL = 'https://${SEATABLE_SERVER_HOSTNAME}:6233/web-apps/apps/api/documents/api.js'" >> /opt/seatable-server/seatable/conf/
echo "ONLYOFFICE_FILE_EXTENSION = ('doc', 'docx', 'ppt', 'pptx', 'xls', 'xlsx', 'odt', 'fodt', 'odp', 'fodp', 'ods', 'fods', 'csv', 'ppsx', 'pps')" >> /opt/seatable-server/seatable/conf/
echo "ONLYOFFICE_JWT_SECRET = '${ONLYOFFICE_JWT_SECRET}'" >> /opt/seatable-server/seatable/conf/

Change SEATABLE_SERVER_HOSTNAME to reflect the hostname of your SeaTable server. Additionally, copy the generated value for ONLYOFFICE_JWT_SECRET from your .env file and paste it in the

4. Download onlyoffice and restart

OnlyOffice is now configured and office documents can be directly edited from within SeaTable after a restart of the SeaTable service.

cd /opt/seatable-compose
docker compose down
docker compose up -d

OnlyOffice takes some some minutes for the initial start. If you get an error message when clicking an office file in SeaTable, be patient. With docker compose logs onlyoffice -f, you can monitor the startup progress.

Try to open https://SEATABLE_SERVER_HOSTNAME:6233/welcome. You should see a welcome page like this.

OnlyOffice Welcome page

Try to open an docx-file from a SeaTable base.

Onlyoffice is ready, if a new browser window opens with your office document. Any user with access to this base can now open this document with OnlyOffice.

Advanced: Custom settings

This is only for onlyoffice experts. You can create and mount a custom configuration file called local-production-linux.json to force some settings.

Create a configuration file in the newly created directory:

cd /opt/onlyoffice
nano local-production-linux.json

Copy the following code block in this file:

  "services": {
    "CoAuthoring": {
      "autoAssembly": {
        "enable": true,
        "interval": "5m"
  "FileConverter": {
    "converter": {
      "downloadAttemptMaxCount": 3

Mount this config file into your onlyoffice block in your docker-compose.yml.

      - /opt/onlyoffice/logs:/var/log/onlyoffice
      - /opt/onlyoffice/data:/var/www/onlyoffice/Data
      - /opt/onlyoffice/lib:/var/lib/onlyoffice
      - /opt/oods/DocumentServer/local-production-linux.json:/etc/onlyoffice/documentserver/local-production-linux.json

Restart OnlyOffice to load the new configuration.

docker compose up -d
