MusicBrainz is an open music encyclopedia that collects music metadata and makes it available to the public.


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 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


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

Compatible with docker-compose v2 schemas.

version: "2.1"
    container_name: musicbrainz
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - BRAINZCODE=<code from MusicBrainz>
      - WEBADDRESS=<ip of host>
      - NPROC=<parameter> #optional
      - </path/to/appdata/config>:/config
      - </path/to/appdata/config>:/data
      - 5000:5000
    restart: unless-stopped

docker cli

docker run -d \
  --name=musicbrainz \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -e BRAINZCODE=<code from MusicBrainz> \
  -e WEBADDRESS=<ip of host> \
  -e NPROC=<parameter> `#optional` \
  -p 5000:5000 \
  -v </path/to/appdata/config>:/config \
  -v </path/to/appdata/config>:/data \
  --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.

Parameter Function
-p 5000 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
-e BRAINZCODE=<code from MusicBrainz> To enter MusicBrainz code. See Setting up the application
-e WEBADDRESS=<ip of host> To set ip for host to allow css to render properly, DO NOT ENTER PORT NUMBER.
-e NPROC=<parameter> To set number of proceses, defaults to 5 if unset.
-v /config Config files for musicbrainz.
-v /data Data files for musicbrainz.

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)


Application Setup

  • For all updates you should pull the latest image, clear all files and folders in /config and /data and reinitiate the database import by (re)starting the docker. We do not officially support upgrading this container in place with existing data sets.

  • If you did not set WEBADDRESS env variable, then AFTER iniatilisation is complete you will need to edit the line sub WEB_SERVER { "localhost:5000" } in file /config/ changing localhost to the ip of your host, this is to allow css to display properly

  • You must register here to receive a MusicBrainz code to allow you to receive database updates, it is free. Get Code here.

  • The initial import and setup of the database can take quite a long time, dependant on your download speed etc, be patient and don't restart the container before it's complete.
  • It appears there are issues with unraid and using /mnt/user/cache/appdata instead of /mnt/cache/appdata, use /mnt/cache/appdata.

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 musicbrainz /bin/bash
  • To monitor the logs of the container in realtime: docker logs -f musicbrainz
  • container version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' musicbrainz
  • 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 (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 musicbrainz
  • Let compose update all containers as necessary: docker-compose up -d
  • or update a single container: docker-compose up -d musicbrainz
  • 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 musicbrainz
  • Delete the container: docker rm musicbrainz
  • 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 musicbrainz
  • 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
cd docker-musicbrainz
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.
