[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.
We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://distribution.github.io/distribution/spec/manifest-v2-2/#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
Simply pulling `lscr.io/linuxserver/lazylibrarian:latest` should retrieve the correct image for your arch, but you can also pull specific arch images via tags.
**64bit 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.
To use this option add the optional environmental variable as detailed in the docker-mods section 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 have set `/books` as ***optional path***, this is because it is the easiest way to get started. While easy to use, it has some drawbacks. Mainly losing the ability to hardlink (TL;DR a way for a file to exist in multiple places on the same file system while only consuming one file worth of space), or atomic move (TL;DR instant file moves, rather than copy+delete) files while processing content.
Use the optional path if you dont understand, or dont want hardlinks/atomic moves.
The folks over at servarr.com wrote a good [write-up](https://wiki.servarr.com/docker-guide#consistent-and-well-planned-paths) on how to get started with this.
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.
| `DOCKER_MODS=linuxserver/mods:universal-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`.

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.
docker inspect -f '{{ index .Config.Labels "build_version" }}' lazylibrarian

```
## 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:
* 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:
```bash
docker image prune
```
### 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:
```bash
docker run --rm \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower \
--run-once lazylibrarian
```
* You can also remove the old dangling images: `docker image prune`
!!! warning
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.
