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.
lscr.io/linuxserver/calibre: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:
This image sets up the calibre desktop app and makes its interface available via Guacamole server in the browser. The interface is available at
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¶
|CUSTOM_PORT||Internal port the container listens on for http if it needs to be swapped from the default 8080.|
|CUSTOM_HTTPS_PORT||Internal port the container listens on for https if it needs to be swapped from the default 8181.|
|CUSTOM_USER||HTTP Basic auth username, abc is default.|
|PASSWORD||HTTP Basic auth password, abc is default. If unset there will be no auth|
|SUBFOLDER||Subfolder for the application if running a subfolder reverse proxy, need both slashes IE |
|TITLE||The page title displayed on the web browser, default "KasmVNC Client".|
|FM_HOME||This is the home directory (landing) for the file manager, default "/config".|
|START_DOCKER||If set to false a container with privilege will not automatically start the DinD Docker setup.|
|DRINODE||If mounting in /dev/dri for DRI3 GPU Acceleration allows you to specify the device to use IE |
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 |
| ||Mount in the host level Docker socket to either interact with it via CLI or use Docker enabled applications.|
| ||Mount a GPU into the container, this can be used in conjunction with the |
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.
docker-compose (recommended, click here for more info)¶
--- version: "2.1" services: calibre: image: lscr.io/linuxserver/calibre:latest container_name: calibre security_opt: - seccomp:unconfined #optional environment: - PUID=1000 - PGID=1000 - TZ=Etc/UTC - PASSWORD= #optional - CLI_ARGS= #optional volumes: - /path/to/data:/config ports: - 8080:8080 - 8181:8181 - 8081:8081 restart: unless-stopped
docker cli (click here for more info)¶
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 \ lscr.io/linuxserver/calibre:latest
Containers 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.

Environment variables from files (Docker secrets)¶
You can set any environment variable from a file by using a special prepend
As an example:
Will set the environment variable
MYVAR based on the contents of the
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
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
PGID=1000, to find yours use
id your_user as below:
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.
Shell access whilst the container is running:
To monitor the logs of the container in realtime:
Container version number:
Image version number:
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¶
You can also remove the old dangling images:
Via Docker Run¶
Update the image:
Stop the running container:
Delete the container:
Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your
/configfolder and settings will be preserved)
You can also remove the old dangling images:
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:
You can also remove the old dangling images:
docker image prune
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.
If you want to make local modifications to these images for development purposes or just to customize the logic:
