[Calibre](https://calibre-ebook.com/) 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.
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](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
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.
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](https://en.wikipedia.org/wiki/Umask) before asking for support.
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`.
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:
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.

We publish various [Docker Mods](https://github.com/linuxserver/docker-mods) to enable additional functionality within the containers. The list of Mods available for this image (if any) can be accessed via the dynamic badge above.
