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 lscr.io/linuxserver/lazylibrarian:latest 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:

x86-64amd64-<version tag>
arm64arm64v8-<version tag>
armhfarm32v7-<version tag>

Application Setup

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

Calibredb import

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


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


Here are some example snippets to help you get started creating a container.

docker-compose (recommended, click here for more info)

version: "2.1"
    image: lscr.io/linuxserver/lazylibrarian:latest
    container_name: lazylibrarian
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - 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 cli (click here for more info)

docker run -d \
  --name=lazylibrarian \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -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 \


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.

-p 5299The port for the LazyLibrarian webinterface
-e PUID=1000for UserID - see below for explanation
-e PGID=1000for GroupID - see below for explanation
-e TZ=Europe/LondonSpecify a timezone to use e.g. Europe/London
`-e DOCKER_MODS=linuxserver/calibre-web:calibrelinuxserver/mods:lazylibrarian-ffmpeg`
-v /configLazyLibrarian config
-v /downloadsDownload location
-v /booksBooks location

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

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" }}' lscr.io/linuxserver/lazylibrarian:latest

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 section above to see if it is recommended for the image.

Below are the instructions for updating containers:

Via Docker Compose

  • Update all images: docker-compose pull
    • or update a single image: docker-compose pull lazylibrarian
  • Let compose update all containers as necessary: docker-compose up -d
    • or update a 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 lscr.io/linuxserver/lazylibrarian:latest
  • 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

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:

    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

Note: 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.

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 https://github.com/linuxserver/docker-lazylibrarian.git
cd docker-lazylibrarian
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/lazylibrarian:latest .

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.
