docsbox

docsbox is a standalone service that allows you to convert office documents, like .docx and .pptx, into more useful filetypes like PDF, for viewing it in browser with PDF.js, or HTML for organizing full-text search of document content.
docsbox uses LibreOffice (via LibreOfficeKit) for document converting.

Settings (env)

REDIS_URL - redis-server url (default: redis://redis:6379/0)
REDIS_JOB_TIMEOUT - job timeout (default: 10 minutes)
ORIGINAL_FILE_TTL - TTL for uploaded file in seconds (default: 10 minutes)

Scaling

Within a single physical server, docsbox can be scaled by docker-compose:

$ docker-compose up
$ docker-compose scale web=4 rqworker=8

For multi-host deployment you'll need to create global syncronized volume (e.g. with flocker), global redis-server and mount it at docker-compose.yml file.
