MusicIP runs very nicely serving up mixes of your local music, especially in conjunction with Logitech Media Server.
Although it's a very old program by now (and unfortunately closed source), I find it still makes mixes with a nice flavour, even better than Echonest in some respects (when that was easily available before Spotify made things difficult).
Launch the container with a command like this:
docker run -d -p 10002:10002 -v <host-music-dir>:/music justifiably/musicip
where is a directory containing music files.
Visit the web server at http://localhost:10002 and add some
music files to analyse, from /music or other directories containing
your music files mounted as volumes so they are visible to the server.
See the example docker-compose.yml.
If you want to keep the database and settings outside the container, you can
map a volume to /home/musicip. This should have a subdirectory
create the directory .MusicMagic and put a mmm.ini file into it,
start with the example included here and read the documentation at
Spicefly.
Make sure the file and directory are owned by UID 1057 (or change the
PUID arg and rebuild).
See extensive information and binaries kindly maintained at Spicefly.com, including documentation of the API.
To interface with Logitech Media Server I use an nginx wrapper which remaps some filenames and extensions, mainly for the historical reason that I ripped most of my CDs and bought iTunes music in m4a format before switching to Flac. Unfortunately the Linux version of MusicIP cannot read m4a files so I generated a shadow tree of lower bitrate mp3 files (also handy for devices).
See musicip.nginx for how to do this with nginx, which seems to
work, more or less. I find it a cleaner solution than the one which
is built into the Spicefly plugin, but YMMV.
