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

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 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

Usage

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

docker

docker create \
  --name=calibre \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -e GUAC_USER=abc `#optional` \
  -e GUAC_PASS=900150983cd24fb0d6963f7d28e17f72 `#optional` \
  -p 8080:8080 \
  -p 8081:8081 \
  -v /path/to/data:/config \
  --restart unless-stopped \
  linuxserver/calibre

docker-compose

Compatible with docker-compose v2 schemas.

version: "2"
services:
  calibre:
    image: linuxserver/calibre
    container_name: calibre
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - GUAC_USER=abc #optional
      - GUAC_PASS=900150983cd24fb0d6963f7d28e17f72 #optional
    volumes:
      - /path/to/data:/config
    ports:
      - 8080:8080
      - 8081:8081
    restart: unless-stopped

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
8080	Calibre desktop gui.
8081	Calibre webserver gui.

Environment Variables (-e)

Env	Function
PUID=1000	for UserID - see below for explanation
PGID=1000	for GroupID - see below for explanation
TZ=Europe/London	Specify a timezone to use EG Europe/London.
GUAC_USER=abc	Username for the calibre desktop gui.
GUAC_PASS=900150983cd24fb0d6963f7d28e17f72	Password's md5 hash for the calibre desktop gui.

Volume Mappings (-v)

Volume	Function
/config	Where calibre should store its database and library.

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)

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 username or password set. Custom usernames and passwords can be set via optional docker environment variables. Keep in mind that the GUACPASS variable accepts the md5 hash of the desired password (the sample above is the hash for abc). The md5 hash can be generated by either of the following commands:

echo -n password | openssl md5

printf '%s' password | md5sum

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.
