[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/).
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.
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`.
*`docker inspect -f '{{ index .Config.Labels "build_version" }}' linuxserver/calibre-web`
## Updating Info
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:
### Via Docker Run/Create
* Update the image: `docker pull linuxserver/calibre-web`
* Stop the running container: `docker stop calibre-web`
* Delete the container: `docker rm calibre-web`
* Recreate a new container with the same docker create parameters as instructed above (if mapped correctly to a host folder, your `/config` folder and settings will be preserved)
* Start the new container: `docker start calibre-web`
* You can also remove the old dangling images: `docker image prune`
### Via Docker Compose
* Update the image: `docker-compose pull linuxserver/calibre-web`
* Let compose update containers as necessary: `docker-compose up -d`
* You can also remove the old dangling images: `docker image prune`
