This is an image for the music server Mopidy.
The image uses a default configuration that allows MPD and HTTP connections from any host.
Run the container once with -v /some/dir:/home/mopidy/.config/mopidy and the default config file will be copied across. Then you can edit as you would with a normal Mopidy install.
All Mopidy data is also stored in this folder for ease of updating.
By default this image contains backend extensions for TuneIn, YTMusic, and Spotify, as well as the frontend Iris, all from pip. You can specify which extra apt and pip packages you want to install though, with the APT_PACKAGES and PIP_PACKAGES env vars. You should set these to space-delimited lists of packages you want installed in the container. Upon boot, the container will make sure these packages are installed.
If you specify the UPDATE env var (set it to anything) the container will update all apt and pip packages before starting (including system packages).
By default this image is configured to output to a Snapserver for use in Mopidy-Multiroom. If you'd like to output audio to a regular device, you can edit the config file and follow the instructions inside under 'audio'.
