Installing ONLYOFFICE Docs

To be able to edit documents in Confluence Cloud, you will need an instance of ONLYOFFICE Docs (Document Server). You can install free Community version or scalable Enterprise Edition.

To install free Community version, use Docker (recommended) or follow these instructions for Debian, Ubuntu, or derivatives.

To install Enterprise Edition, follow instructions here.

Community Edition vs Enterprise Edition comparison can be found here.

App configuration ⚙️

Administrators can configure ONLYOFFICE app via the Manage Apps section in Confluence Cloud (Apps -> Manage Apps -> ONLYOFFICE -> Configure). On the configuration page, set up:

  • Document Editing Service Address: The URL of the installed ONLYOFFICE Docs (Document Server).

  • Secret key: Enables JWT to protect your documents from unauthorized access (further information can be found here).

  • JWT Header: Name of the header to pass the JWT in, if you use a custom header in your server

App usage

In the Pages module, you can attach files to the created pages: open the right context menu, click on the Attachments item and upload a file from the device.

The uploaded file will appear in the Attachments list. To launch the editor, click Edit in ONLYOFFICE. The file opens in the same window. The changes made are saved in the same file.

Note: If a file is not supported by ONLYOFFICE, the app will show an error message.
