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

Our images support multiple architectures such as x86-64, arm64 and armhf. 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 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	Tag
x86-64	amd64-latest
arm64	arm64v8-latest
armhf	arm32v7-latest

Version Tags

This image provides various versions that are available via tags. latest tag usually provides the latest stable version. Others are considered under development and caution must be exercised when using them.

Tag	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

x86-64 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 detailed above 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

To reverse proxy with our Letsencrypt docker container we include a preconfigured reverse proxy config, for other instances of Nginx use the following location block:

        location /calibre-web {
                proxy_pass              http://<your-ip>:8083;
                proxy_set_header        Host            $http_host;
                proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header        X-Scheme        $scheme;
                proxy_set_header        X-Script-Name   /calibre-web;
        }

Usage

Here are some example snippets to help you get started creating a container.

docker-compose (recommended, click here for more info)

---
version: "2.1"
services:
  calibre-web:
    image: lscr.io/linuxserver/calibre-web
    container_name: calibre-web
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - DOCKER_MODS=linuxserver/calibre-web:calibre #optional
      - OAUTHLIB_RELAX_TOKEN_SCOPE=1 #optional
    volumes:
      - /path/to/data:/config
      - /path/to/calibre/library:/books
    ports:
      - 8083:8083
    restart: unless-stopped

docker cli (click here for more info)

docker run -d \
  --name=calibre-web \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -e DOCKER_MODS=linuxserver/calibre-web:calibre `#optional` \
  -e OAUTHLIB_RELAX_TOKEN_SCOPE=1 `#optional` \
  -p 8083:8083 \
  -v /path/to/data:/config \
  -v /path/to/calibre/library:/books \
  --restart unless-stopped \
  lscr.io/linuxserver/calibre-web

Parameters

Container 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.

Parameter	Function
-p 8083	WebUI
-e PUID=1000	for UserID - see below for explanation
-e PGID=1000	for GroupID - see below for explanation
-e TZ=Europe/London	Specify a timezone to use EG Europe/London.
-e DOCKER_MODS=linuxserver/calibre-web:calibre	#optional & x86-64 only Adds the ability to perform ebook conversion
-e OAUTHLIB_RELAX_TOKEN_SCOPE=1	Optionally set this to allow Google OAUTH to work
-v /config	Where calibre-web stores the internal database and config.
-v /books	Where your preexisting calibre database is located.

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

Updating Info

Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (ie. nextcloud, plex), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.

Below are the instructions for updating containers:

Via Docker Compose

• Update all images: docker-compose pull
  • or update a single image: docker-compose pull calibre-web
• Let compose update all containers as necessary: docker-compose up -d
  • or update a single container: docker-compose up -d calibre-web
• You can also remove the old dangling images: docker image prune

Via Docker Run

• Update the image: docker pull lscr.io/linuxserver/calibre-web
• Stop the running container: docker stop calibre-web
• Delete the container: docker rm calibre-web
• Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your /config folder and settings will be preserved)
• You can also remove the old dangling images: docker image prune

Via Watchtower auto-updater (only use if you don't remember the original parameters)

• Pull the latest image at its tag and replace it with the same env variables in one run:

  docker run --rm \
  -v /var/run/docker.sock:/var/run/docker.sock \
  containrrr/watchtower \
  --run-once calibre-web
  

• You can also remove the old dangling images: docker image prune

Note: We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers. In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using Docker Compose.

Image Update Notifications - Diun (Docker Image Update Notifier)

• We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.

Building locally

If you want to make local modifications to these images for development purposes or just to customize the logic:

git clone https://github.com/linuxserver/docker-calibre-web.git
cd docker-calibre-web
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/calibre-web:latest .

The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static

docker run --rm --privileged multiarch/qemu-user-static:register --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
