linuxserver/calibre

Calibre is a powerful and easy to use e-book manager. Users say it’s outstanding and a must-have. It’ll allow you to do nearly everything and it takes things a step beyond normal e-book software. It’s also completely free and open source and great for both casual users and computer experts.

Supported Architectures

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

Simply pulling ghcr.io/linuxserver/calibre 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	latest

Application Setup

This image sets up the calibre desktop app and makes its interface available via Guacamole server in the browser. The interface is available at http://your-ip:8080.

By default, there is no password set for the main gui. Optional environment variable PASSWORD will allow setting a password for the user abc.

Port 8081 is reserved for Calibre's built-in webserver, which can be enabled within the desktop app settings, and the internal port must be set to 8081 although it will then be available at the host mapped port for external access.

You can access advanced features of the Guacamole remote desktop using ctrl+alt+shift enabling you to use remote copy/paste and different languages.

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:
    image: ghcr.io/linuxserver/calibre
    container_name: calibre
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - PASSWORD= #optional
      - CLI_ARGS= #optional
    volumes:
      - /path/to/data:/config
    ports:
      - 8080:8080
      - 8081:8081
    restart: unless-stopped

docker cli (click here for more info)

docker run -d \
  --name=calibre \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -e PASSWORD= `#optional` \
  -e CLI_ARGS= `#optional` \
  -p 8080:8080 \
  -p 8081:8081 \
  -v /path/to/data:/config \
  --restart unless-stopped \
  ghcr.io/linuxserver/calibre

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 8080	Calibre desktop gui.
-p 8081	Calibre webserver gui.
-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 PASSWORD=	Optionally set a password for the gui.
-e CLI_ARGS=	Optionally pass cli start arguments to calibre.
-v /config	Where calibre should store its database and library.

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 /bin/bash
• To monitor the logs of the container in realtime: docker logs -f calibre
• container version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' calibre
• image version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' ghcr.io/linuxserver/calibre

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

Via Docker Run

• Update the image: docker pull ghcr.io/linuxserver/calibre
• Stop the running container: docker stop calibre
• Delete the container: docker rm calibre
• 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

• 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.git
cd docker-calibre
docker build \
  --no-cache \
  --pull \
  -t ghcr.io/linuxserver/calibre: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.
