buvis/mopidy repository overview

⁠Purpose

Run Mopidy⁠ in a container. Works on amd64,arm64,arm. I use it on Raspberries a lot.

⁠Prepare

1. Create directories for Mopidy⁠: sudo mkdir -p {/var/local/docker/mopidy/config,/var/local/docker/mopidy/data,/var/local/docker/mopidy/media}
2. Create kah user: sudo useradd -u 568 kah (kah is the user executing the entrypoint in the container)
3. Let Mopidy control audio devices: sudo usermod -G audio kah
4. Make kah owner of its directories: sudo chown -R kah:audio /var/local/docker/mopidy
5. Get mopidy.conf from source repository⁠
6. Edit mopidy.conf to configure Mopidy⁠. Don't forget to replace the secrets by their real content.
7. Copy mopidy.conf to host's /var/local/docker/mopidy/config/mopidy.conf
8. Mount or copy media and playlists to host's /var/local/docker/mopidy/media For example, mount from NAS over NFS:

# add this to /etc/fstab
<NAS_IP>:/mnt/tank/media/music /var/local/docker/mopidy/media nfs ro,auto,_netdev,noatime,nolock,bg,intr,tcp,actimeo=1800 0 0

⁠Run

docker run \
  --detach \
  --restart=always \
  --name mopidy \
  --publish 6600:6600 \
  --publish 6680:6680 \
  --user kah:audio \
  --group-add $(getent group audio | cut -d: -f3) \
  --device /dev/snd \
  --mount type=bind,source=/var/local/docker/mopidy/data,target=/app \
  --mount type=bind,source=/var/local/docker/mopidy/config,target=/config,readonly \
  --mount type=bind,source=/var/local/docker/mopidy/media,target=/media \
  buvis/mopidy

⁠Use host's pulseaudio server

1. Modify the run command above by replacing --device /dev/snd \ by --env PULSE_SERVER=tcp:<HOST_IP>:34567 \
2. Set the output = pulsesink server=<HOST_IP>:34567 in mopidy.conf [audio] section

⁠Post-run activities

Mopidy-Tidal⁠ requires authentication to be done after running Mopidy⁠.

1. Get container's logs: docker logs mopidy
2. Get OAuth link from line looking like: "Visit link.tidal.com/AAAAA to log in, the code will expire in 300 seconds"
3. Copy&paste the link to your browser and approve
