# OnlyOffice Document Server

Self-hosted document editing server. Integrates with Nextcloud and FileBrowser
to provide collaborative editing of ODT, DOCX, XLSX, and PPTX files.

## JWT Secret
The JWT secret is stored in \`.env\` (chmod 600). If you rotate it, update:
- Nextcloud: Settings > OnlyOffice > JWT Secret
- Any other integrations using this server

JWT Secret (at install time): see \`JWT_SECRET\` in .env

## Nextcloud Integration
If Nextcloud was running at install time, the OnlyOffice app was auto-configured.
To reconfigure or verify:
\`\`\`bash
docker exec --user www-data nextcloud php occ config:app:get onlyoffice DocumentServerUrl
docker exec --user www-data nextcloud php occ config:app:get onlyoffice jwt_secret
\`\`\`

## FileBrowser Integration
Set \`officeServer: "http://onlyoffice:80/"\` in FileBrowser's config.yaml, then
restart FileBrowser.

## Manage
\`\`\`bash
cd $DIR
docker compose up -d                          # start
docker compose down                           # stop
docker compose logs -f                        # logs
docker compose pull && docker compose up -d   # update
\`\`\`
