Lazylibrarian 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.

Supported Architectures

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.
Simply pulling should retrieve the correct image for your arch, but you can also pull specific arch images via tags.
The architectures supported by this image are:
amd64-<version tag>
arm64v8-<version tag>
arm32v7-<version tag>

Application Setup

Access the webui at http://<your-ip>:5299/home, for more information check out Lazylibrarian.

Calibredb import

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. 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 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


By adding linuxserver/mods:lazylibrarian-ffmpeg to your DOCKER_MODS environment variable you can install ffmpeg into your container on startup. This allows you to use the audiobook conversion features of LazyLibrarian. You can enable it in the Web UI under Settings > Processing > External Programs by setting the ffmpeg path to ffmpeg.

Media folders

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 wrote a good write-up on how to get started with this.


To help you get started creating a container from this image you can either use docker-compose or the docker cli.
version: "2.1"
container_name: lazylibrarian
- PUID=1000
- PGID=1000
- TZ=Etc/UTC
- DOCKER_MODS=linuxserver/calibre-web:calibre|linuxserver/mods:lazylibrarian-ffmpeg #optional
- /path/to/data:/config
- /path/to/downloads/:/downloads
- /path/to/data/:/books #optional
- 5299:5299
restart: unless-stopped
docker run -d \
--name=lazylibrarian \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Etc/UTC \
-e DOCKER_MODS=linuxserver/calibre-web:calibre|linuxserver/mods:lazylibrarian-ffmpeg `#optional` \
-p 5299:5299 \
-v /path/to/data:/config \
-v /path/to/downloads/:/downloads \
-v /path/to/data/:/books `#optional` \
--restart unless-stopped \


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.

Miscellaneous Options

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.
As an example:
-e FILE__PASSWORD=/run/secrets/mysecretpassword
Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

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 before asking for support.

User / Group Identifiers

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.
Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.
In this instance PUID=1000 and PGID=1000, to find yours use id user as below:
$ id username
uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Docker Mods

We publish various 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.
