linuxserver/calibre-web

Calibre-web is a web app providing a clean interface for browsing, reading and downloading eBooks using an existing Calibre database. It is also possible to integrate google drive and edit metadata and your calibre library through the app itself.

This software is a fork of library and licensed under the GPL v3 License.

Supported Architectures

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling lscr.io/linuxserver/calibre-web:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture	Available	Tag
x86-64	✅	amd64-<version tag>
arm64	✅	arm64v8-<version tag>
armhf	✅	arm32v7-<version tag>

Version Tags

This image provides various versions that are available via tags. Please read the descriptions carefully and exercise caution when using unstable or development tags.

Tag	Available	Description
latest	✅	Releases of Calibre-Web
nightly	✅	Commits to the master branch of Calibre-Web

Application Setup

Webui can be found at http://your-ip:8083

On the initial setup screen, enter /books as your calibre library location.

Default admin login: Username: admin Password: admin123

Unrar is included by default and needs to be set in the Calibre-Web admin page (Basic Configuration:External Binaries) with a path of /usr/bin/unrar

64bit only We have implemented the optional ability to pull in the dependencies to enable ebook conversion utilising Calibre, this means if you don't require this feature the container isn't uneccessarily bloated but should you require it, it is easily available. This optional layer will be rebuilt automatically on our CI pipeline upon new Calibre releases so you can stay up to date. To use this option add the optional environmental variable as shown in the docker-mods section to pull an addition docker layer to enable ebook conversion and then in the Calibre-Web admin page (Basic Configuration:External Binaries) set the Path to Calibre E-Book Converter to /usr/bin/ebook-convert

This image contains the kepubify ebook conversion tool (MIT License) to convert epub to kepub. In the Calibre-Web admin page (Basic Configuration:External Binaries) set the Path to Kepubify E-Book Converter to /usr/bin/kepubify

Usage

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Ports (-p)

Parameter	Function
8083	WebUI

Environment Variables (-e)

Env	Function
PUID=1000	for UserID - see below for explanation
PGID=1000	for GroupID - see below for explanation
TZ=Etc/UTC	specify a timezone to use, see this list.
DOCKER_MODS=linuxserver/mods:universal-calibre	#optional & x86-64 only Adds the ability to perform ebook conversion
OAUTHLIB_RELAX_TOKEN_SCOPE=1	Optionally set this to allow Google OAUTH to work

Volume Mappings (-v)

Volume	Function
/config	Where calibre-web stores the internal database and config.
/books	Where your preexisting calibre database is located.

Miscellaneous Options

Parameter	Function

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using 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 any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Docker Mods

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info

• Shell access whilst the container is running:
  • docker exec -it calibre-web /bin/bash
• To monitor the logs of the container in realtime:
  • docker logs -f calibre-web
• Container version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' calibre-web
• Image version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/calibre-web:latest
