docker compose up -d 

This will pull everything that you need. Then you can just enter something like this 



Make sure that you change the JWT_SECRET to something more secure. Also the document server must be accessible from the outside. When you go to the URL you should see something appear. 

1. Running OnlyOffice Community Server, which includes Documents.
2. If not running OnlyOffice in Docker, you'll find your 'secret' in /etc/onlyoffice/documentserver/local.json. See this page for more info.
3. If OnlyOffice is running on a different domain than your SmarterMail, which it probably is, you'll need to  remove x-frame-src header in onlyoffice server nginx config. Replace it with Content-Security-Policy frame-ancestors so you can list the domains you wanted to allow access to show onlyoffice in a frame. SM is loading the OnlyOffice Document Editor in iframe.
   1. edit /etc/nginx/sites-enabled/onlyoffice
   2. comment out line with add_header X-Frame-Options $header_x_frame_options;
   3. add this after the line commented out, add_header Content-Security-Policy "frame-ancestors 'self' https://your-smartermail-server.tld;";
4. Need to use https://your-onlyoffice-server.tld/ds-vpath in the SM setting for the OpenOffice URL. If you're not using Community Server, you most likely don't need to do this.
