Calibre Web App


Calibre Web is a web app for browsing, reading and downloading eBooks stored in a Calibre database.

Importing existing calibre database

To import an existing Calibre database, do the following:

  • Stop the app
  • Copy the database into /app/data/library using the File Manager
  • Start the app


By default, the library is located at /app/data/library. This can be moved to another location by copying over the existing library to the new cloudron. Note that the library files must have the owner cloudron.

To start with a fresh library is tricky since calibredb offers no straightforward command to create an empty library. As a workaround, run the following commands using the Web Terminal:

# cd /path/to/library
# chown cloudron:cloudron /path/to/library
# gosu cloudron:cloudron calibredb restore_database --really-do-it --with-library /path/to/library
