linuxserver/lidarr

Lidarr is a music collection manager for Usenet and BitTorrent users. It can monitor multiple RSS feeds for new tracks from your favorite artists and will grab, sort and rename them. It can also be configured to automatically upgrade the quality of files already downloaded when a better quality format becomes available.

Supported Architectures

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 and our announcement here.

Simply pulling lscr.io/linuxserver/lidarr 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	Tag
x86-64	amd64-latest
arm64	arm64v8-latest
armhf	arm32v7-latest

Version Tags

This image provides various versions that are available via tags. latest tag usually provides the latest stable version. Others are considered under development and caution must be exercised when using them.

Tag	Description
latest	Stable Lidarr releases.
develop	Develop Lidarr Releases.
nightly	Nightly Lidarr Releases.

Application Setup

Access the webui at <your-ip>:8686, for more information check out Lidarr.

Special Note: Following our current folder structure will result in an inability to hardlink from your downloads to your Music folder because they are on seperate volumes. To support hardlinking, simply ensure that the Music and downloads data are on a single volume. For example, if you have /mnt/storage/Music and /mnt/storage/downloads/completed/Music, you would want something like /mnt/storage:/media for your volume. Then you can hardlink from /media/downloads/completed to /media/Music.

Another item to keep in mind, is that within lidarr itself, you should then map your download client folder to your lidarr folder: Settings -> Download Client -> advanced -> remote path mappings. I input the host of my download client (matches the download client defined) remote path is /downloads/Music (relative to the internal container path) and local path is /media/downloads/completed/Music, assuming you have folders to seperate your downloaded data types.

Media folders

We have set /music and /downloads as optional paths, 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 paths 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.

Usage

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

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

---
version: "2.1"
services:
  lidarr:
    image: lscr.io/linuxserver/lidarr
    container_name: lidarr
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - /path/to/appdata/config:/config
      - /path/to/music:/music #optional
      - /path/to/downloads:/downloads #optional
    ports:
      - 8686:8686
    restart: unless-stopped

docker cli (click here for more info)

docker run -d \
  --name=lidarr \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -p 8686:8686 \
  -v /path/to/appdata/config:/config \
  -v /path/to/music:/music `#optional` \
  -v /path/to/downloads:/downloads `#optional` \
  --restart unless-stopped \
  lscr.io/linuxserver/lidarr

Parameters

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.

Parameter	Function
`-p 8686`	Application WebUI
`-e PUID=1000`	for UserID - see below for explanation
`-e PGID=1000`	for GroupID - see below for explanation
`-e TZ=Europe/London`	Specify a timezone to use EG Europe/London.
`-v /config`	Configuration files for Lidarr.
`-v /music`	Music files (See note in Application setup).
`-v /downloads`	Path to your download folder for music (See note in Application setup).

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.

Support Info

Shell access whilst the container is running: docker exec -it lidarr /bin/bash
To monitor the logs of the container in realtime: docker logs -f lidarr
container version number
- docker inspect -f '{{ index .Config.Labels "build_version" }}' lidarr
image version number
- docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/lidarr

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 lidarr
Let compose update all containers as necessary: docker-compose up -d
- or update a single container: docker-compose up -d lidarr
You can also remove the old dangling images: docker image prune

Via Docker Run

Update the image: docker pull lscr.io/linuxserver/lidarr
Stop the running container: docker stop lidarr
Delete the container: docker rm lidarr
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 lidarr

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-lidarr.git
cd docker-lidarr
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/lidarr: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.
