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:

Architecture Available Tag
x86-64 amd64-<version tag>
arm64 arm64v8-<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.

    container_name: lazylibrarian
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
      - DOCKER_MODS=linuxserver/mods:universal-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 cli (click here for more info)

docker run -d \
  --name=lazylibrarian \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Etc/UTC \
  -e DOCKER_MODS=linuxserver/mods:universal-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 \


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.

Ports (-p)

Parameter Function
5299 The port for the LazyLibrarian webinterface

Environment Variables (-e)

Env Function
PUID=1000 for UserID - see below for explanation
PGID=1000 for GroupID - see below for explanation
TZ=Etc/UTC specify a timezone to use, see this list.
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)

Volume Mappings (-v)

Volume Function
/config LazyLibrarian config
/downloads Download location
/books Books location

Miscellaneous Options

Parameter Function

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__MYVAR=/run/secrets/mysecretvariable

Will set the environment variable MYVAR based on the contents of the /run/secrets/mysecretvariable 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 your_user as below:

id your_user

Example output:

uid=1000(your_user) gid=1000(your_user) groups=1000(your_user)

Docker Mods

Docker Mods Docker Universal 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.

Support Info

  • Shell access whilst the container is running:

    docker exec -it lazylibrarian /bin/bash
  • To monitor the logs of the container in realtime:

    docker logs -f lazylibrarian
  • Container version number:

    docker inspect -f '{{ index .Config.Labels "build_version" }}' lazylibrarian
  • Image version number:

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

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 (noted in the relevant, we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.

Below are the instructions for updating containers:

Via Docker Compose

  • Update images:

    • All images:

      docker-compose pull
    • Single image:

      docker-compose pull lazylibrarian
  • Update containers:

    • All containers:

      docker-compose up -d
    • Single container:

      docker-compose up -d lazylibrarian
  • You can also remove the old dangling images:

    docker image prune

Via Docker Run

  • Update the image:

    docker pull
  • Stop the running container:

    docker stop lazylibrarian
  • Delete the container:

    docker rm lazylibrarian
  • 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

Image Update Notifications - Diun (Docker Image Update Notifier)


We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.

Building locally

If you want to make local modifications to these images for development purposes or just to customize the logic:

git clone
cd docker-lazylibrarian
docker build \
  --no-cache \
  --pull \
  -t .

The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static

docker run --rm --privileged multiarch/qemu-user-static:register --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
