[Lazylibrarian](https://lazylibrarian.gitlab.io/) is a program to follow authors and grab metadata for all your digital reading needs. It uses a combination of Goodreads Librarything and optionally GoogleBooks as sources for author info and book info. This container is based on the DobyTang fork.
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.
| `DOCKER_MODS=linuxserver/calibre-web:calibre|linuxserver/mods:lazylibrarian-ffmpeg` | Allows additional functionality to be added, e.g. the Calibredb import program (optional, more info below) |
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`.
**x86-64 only** We have implemented the optional ability to pull in the dependencies to enable the Calibredb import program:, 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 LazyLibrarian config page (Processing:Calibredb import program:) set the path to converter tool to `/usr/bin/calibredb`

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.
