[Calibre-web](https://github.com/janeczku/calibre-web) is a web app providing a clean interface for browsing, reading and downloading eBooks using an existing Calibre database. It is also possible to integrate google drive and edit metadata and your calibre library through the app itself.
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/).
This image provides various versions that are available via tags. `latest` tag usually provides the latest stable version. Others are considered under development and caution must be exercised when using them.
| Tag | Description |
| :----: | --- |
| latest | Releases of Calibre-Web |
| nightly | Commits to the master branch of Calibre-Web |
On the initial setup screen, enter `/books` as your calibre library location.
**Default admin login:**
*Username:* admin
*Password:* admin123
Unrar is included by default and needs to be set in the Calibre-Web admin page (Basic Configuration:External Binaries) with a path of `/usr/bin/unrar`
**x86-64 only** We have implemented the optional ability to pull in the dependencies to enable ebook conversion utilising Calibre, this means if you don't require this feature the container isn't uneccessarily bloated but should you require it, it is easily available.
This optional layer will be rebuilt automatically on our CI pipeline upon new Calibre releases so you can stay up to date.
To use this option add the optional environmental variable as detailed above to pull an addition docker layer to enable ebook conversion and then in the Calibre-Web admin page (Basic Configuration:External Binaries) set the **Path to Calibre E-Book Converter** to `/usr/bin/ebook-convert`
This image contains the [kepubify](https://pgaskin.net/kepubify/) ebook conversion tool (MIT License) to convert epub to kepub. In the Calibre-Web admin page (Basic Configuration:External Binaries) set the **Path to Kepubify E-Book Converter** to `/usr/bin/kepubify`
To reverse proxy with our Letsencrypt docker container we include a preconfigured reverse proxy config, for other instances of Nginx use the following location block:
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.
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`.

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) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.
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](#application-setup) section above to see if it is recommended for the image.
Below are the instructions for updating containers:
* Stop the running container: `docker stop calibre-web`
* Delete the container: `docker rm calibre-web`
* 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)
**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](https://docs.linuxserver.io/general/docker-compose).
* We recommend [Diun](https://crazymax.dev/diun/) for update notifications. Other tools that automatically update containers unattended are not recommended or supported.
* **13.01.21:** - Rebase to Ubuntu Focal, see [here](https://docs.linuxserver.io/faq#my-host-is-incompatible-with-images-based-on-ubuntu-focal) for troubleshooting armhf.
