  • Send eBooks to Kindle devices with the click of a button
  • Support for reading eBooks directly in the browser (.txt, .epub, .pdf)
  • Upload new books in PDF, epub, fb2 format
  • Support for Calibre custom columns
  • Fine grained per-user permissions
  • Self update capability

If you want to know more you can head over to the Calibre Web project site:

And if you are interested in the original Calibre ebook management tool then look at the project site:


2017-11-04 - v1.1.10

  • added support for a configuration directory (as asked in ticket #13),
    where the configuration related files like app.db and gdrive.db will be stored;
    be aware that metadata.db will be still stored at the books directory which is required by the original Calibre application
  • new options -v <your Calibre Web config folder>:/calibre-web/config and -e USE_CONFIG_DIR=true to setup the configuration directory

For previous changes see at full changelog.


  • running Calibre Web under its own user (not root)
  • changing of the UID and GID for the Calibre Web user
  • no usage of NGINX inside the container, only the Calibre Web application is served as single application without any supervisor
  • Google Drive integration is included
  • creation of gdrive.db symlink at /books/gdrive.db for external access like backup possibility
  • creation of app.db symlink at /books/app.db for external access like backup possibility

Hints & Tips

  • if you need SSL support similiar to the original Docker Container janeczku/calibre-web then use an additional NGINX or Apache HTTP Server as Reverse-Proxy, e.g see jwilder/nginx-proxy
  • if you don't specify PGID and PUID values the default PGID and PUID of the image are used,
    and if they are used then the mapped host volume/directory which is alligned to /books must have read-write-execute permission for others , otherwise the configuration of Calibre-Web can't be finished :-|
  • for Synology Users - don't map a top-level volume directory from the NAS as /books volume, e.g. /volume1/books because it results into problems with directory permissons. Create instead a subdirectory calibre at /volume1/books and map then /volume1/books/calibre as volume for /books

Configuration at first launch

  1. Point your browser to http://hostname:<HTTP PORT> e.g. http://hostname:8083
  2. Set Location of your Calibre books folder to the path of the folder where you mounted your Calibre folder in the container, which is by default \books.
    So enter at the field Location of Calibre database the mapped volume \books.
  3. Hit Submit then Login.

Default admin login:

  • Username: admin
  • Password: admin123

After successful login change the default password and set the email adress.

To access the OPDS catalog feed, point your Ebook Reader to http://hostname:<HTTP PORT>/opds


Create the container:

docker create --name=calibre-web --restart=always \
-v <your Calibre books folder>:/books \
[-v <your Calibre Web config folder>:/calibre-web/config \]
[-e USE_CONFIG_DIR=true \]
[-e APP_REPO= \]
[-e APP_BRANCH=master \]
[-e CONTAINER_TIMEZONE=<container timezone value> \]
[-e PGID=<group ID (gid)> -e PUID=<user ID (uid)> \]
-p <HTTP PORT>:8083 \


docker create --name=calibre-web --restart=always \
-v /volume1/books/calibre:/books \
-v /etc/localtime:/etc/localtime:ro \
-e PGID=65539 -e PUID=1029 \
-p 8083:8083 \


docker create --name=calibre-web --restart=always \
-v /volume1/books/calibre:/books \
-v /volume1/docker/apps/calibre-web/config:/calibre-web/config \
-e USE_CONFIG_DIR=true \
-e PGID=65539 -e PUID=1029 \
-p 8083:8083 \

Start the container:

docker start calibre-web



The parameters are split into two parts which are separated via colon.
The left side describes the host and the right side the container.
For example a port definition looks like this -p external:internal and defines the port mapping from internal (the container) to external (the host).
So -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080.
Accessing http://'host':8080 (e.g. would then show you what's running INSIDE the container on port 80.


  • -p 8083 - http port for the web user interface
  • -v /books - local path which contains the Calibre books and the necessary metadata.db which holds all collected meta-information of the books
  • -v /etc/localhost - for timesync - optional
  • -v /calibre-web/config - local path for Calibre Web config files, like app.db and gdrive.db; IMPORTANT: the environment variable USE_CONFIG_DIR must be set to true - optional
  • -e USE_CONFIG_DIR=true - activate the usage of a dedicated configuration directory, otherwise the books directory will be used (default) - optional
  • -e APP_REPO - set it to the Calibre Web GitHub repository; by default it uses - optional
  • -e APP_BRANCH - set which Calibre Web GitHub repository branch you want to use, master (default branch) - optional
  • -e SET_CONTAINER_TIMEZONE - set it to true if the specified CONTAINER_TIMEZONE should be used - optional
  • -e CONTAINER_TIMEZONE - container timezone as found under the directory /usr/share/zoneinfo/ - optional
  • -e PGID for GroupID - see below for explanation - optional
  • -e PUID for UserID - see below for explanation - optional

Container Timezone

In the case of the Synology NAS it is not possible to map /etc/localtime for timesync, and for this and similar case
set SET_CONTAINER_TIMEZONE to true and specify with CONTAINER_TIMEZONE which timezone should be used.
The possible container timezones can be found under the directory /usr/share/zoneinfo/.


  • UTC - this is the default value if no value is set
  • Europe/Berlin
  • Europe/Vienna
  • America/New_York
  • ...

Once the container is running you can get all possible timezones as tree via the command docker exec -it <CONTAINER> tree /usr/share/zoneinfo

See also at possible timezone values.

Don't use the value localtime because it results into: failed to access '/etc/localtime': Too many levels of symbolic links

User / Group Identifiers

Sometimes when using data volumes (-v flags) permissions issues can arise between the host OS and the container. We avoid this issue by allowing you to specify the user PUID and group PGID. Ensure the data volume directory on the host is owned by the same user you specify and it will "just work" ™.

In this instance PUID=1001 and PGID=1001. To find yours use id user as below:

  $ id <dockeruser>
    uid=1001(dockeruser) gid=1001(dockergroup) groups=1001(dockergroup)


Shell access whilst the container is running: docker exec -it calibre-web /bin/bash

Upgrade to the latest version of Calibre Web: docker restart calibre-web

To monitor the logs of the container in realtime: docker logs -f calibre-web

To monitor the logs of Calibre Web: docker exec -it calibre-web tail -f /calibre-web/app/calibre-web.log

Show used base image version number of Calibre Web: docker inspect -f '{{ index .Config.Labels "image.base.version" }}' calibre-web

Show used image version number of Calibre Web: docker inspect -f '{{ index .Config.Labels "image.version" }}' calibre-web

For Synology NAS users

Login into the DSM Web Management

  • Open the Control Panel
  • Control Panel > Privilege > Group and create a new one with the name 'docker'
  • add the permissions for the directories 'downloads', 'video' and so on
  • disallow the permissons to use the applications
  • Control Panel > Privilege > User and create a new on with name 'docker' and assign this user to the group 'docker'

Connect with SSH to your NAS

  • after sucessful connection change to the root account via

    sudo -i


    sudo su -

    for the password use the same one which was used for the SSH authentication.

  • create a 'docker' directory on your volume (if such doesn't exist)

    mkdir -p /volume1/docker/
    chown root:root /volume1/docker/
  • get your Docker User ID and Group ID of your previously created user and group

    id docker
    uid=1029(docker) gid=100(users) groups=100(users),65539(docker)
  • get the Docker image

    docker pull technosoft2000/calibre-web
  • create a Docker container (take care regarding the user ID and group ID, change timezone and port as needed)

    docker create --name=calibre-web --restart=always \
    -v /volume1/books/calibre:/books \
    -e CONTAINER_TIMEZONE=Europe/Vienna \
    -e PGID=65539 -e PUID=1029 \
    -p 8083:8083 \
  • check if the Docker container was created successfully

    docker ps -a
    CONTAINER ID        IMAGE                           COMMAND                CREATED             STATUS              PORTS               NAMES
