This is an image for the snapcast client (https://github.com/badaix/snapcast).
By default, the client connects to "snapserver", so if you already have a snapserver
container running with
--name snapserver, the client should connect to it. To play
audio, the client needs access to the sound device, so you must give it access when
running the container
docker run --rm --name snapclient --net=snapcast_nw --device=/dev/snd snapclient
