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 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:
amd64-<version tag>
arm64v8-<version tag>

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 or https://your-ip:8181.
By default, there is no password set for the main gui. Optional environment variable PASSWORD will allow setting a password for the user abc, via http auth.
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.

Options in all KasmVNC based GUI containers

This container is based on Docker Baseimage KasmVNC which means there are additional environment variables and run configurations to enable or disable specific functionality.

Optional environment variables

Internal port the container listens on for http if it needs to be swapped from the default 8080.
Internal port the container listens on for https if it needs to be swapped from the default 8181.
HTTP Basic auth username, abc is default.
HTTP Basic auth password, abc is default. If unset there will be no auth
Subfolder for the application if running a subfolder reverse proxy, need both slashes IE /subfolder/
The page title displayed on the web browser, default "KasmVNC Client".
This is the home directory (landing) for the file manager, default "/config".
If set to false a container with privilege will not automatically start the DinD Docker setup.
If mounting in /dev/dri for DRI3 GPU Acceleration allows you to specify the device to use IE /dev/dri/renderD128

Optional run configurations

Will start a Docker in Docker (DinD) setup inside the container to use docker in an isolated environment. For increased performance mount the Docker directory inside the container to the host IE -v /home/user/docker-data:/var/lib/docker.
-v /var/run/docker.sock:/var/run/docker.sock
Mount in the host level Docker socket to either interact with it via CLI or use Docker enabled applications.
--device /dev/dri:/dev/dri
Mount a GPU into the container, this can be used in conjunction with the DRINODE environment variable to leverage a host video card for GPU accelerated appplications. Only Open Source drivers are supported IE (Intel,AMDGPU,Radeon,ATI,Nouveau)

Lossless mode

This container is capable of delivering a true lossless image at a high framerate to your web browser by changing the Stream Quality preset to "Lossless", more information here. In order to use this mode from a non localhost endpoint the HTTPS port on 8181 needs to be used. If using a reverse proxy to port 8080 specific headers will need to be set as outlined here.


To help you get started creating a container from this image you can either use docker-compose or the docker cli.
version: "2.1"
container_name: calibre
- seccomp:unconfined #optional
- PUID=1000
- PGID=1000
- TZ=Etc/UTC
- PASSWORD= #optional
- CLI_ARGS= #optional
- /path/to/data:/config
- 8080:8080
- 8181:8181
- 8081:8081
restart: unless-stopped
docker run -d \
--name=calibre \
--security-opt seccomp=unconfined `#optional` \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Etc/UTC \
-e PASSWORD= `#optional` \
-e CLI_ARGS= `#optional` \
-p 8080:8080 \
-p 8181:8181 \
-p 8081:8081 \
-v /path/to/data:/config \
--restart unless-stopped \


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)

Calibre desktop gui.
Calibre desktop gui HTTPS.
Calibre webserver gui.

Environment Variables (-e)

for UserID - see below for explanation
for GroupID - see below for explanation
specify a timezone to use, see this list.
Optionally set a password for the gui.
Optionally pass cli start arguments to calibre.

Volume Mappings (-v)

Where calibre should store its database and library.

Miscellaneous Options

--security-opt seccomp=unconfined
For Docker Engine only, many modern gui apps need this to function as syscalls are unkown to Docker.

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.
