Dockerized Snapcast setup, snapclient on basically any Linux device with a USB port and space for docker

[kerta1n]

0. Install docker compose on UNRAID

0.5. Make sure you have a usable Spotify Premium account and it's login credentials

1. Create the snapserver compose file (librespot working, shairport not tested as I don't regularly have access to Apple devices): compose.yml.txt

1.5. For the Spotify login, configure in snapserver.conf:

[stream]
source = librespot:///librespot?name=Spotify&devicename=PREFD_SPOT_DEV_NAME&bitrate=320&volume=50&username=UR_SPOT_EMAIL@example.com&password=UR_SPOT_PASS
#bitrate can be in 160 as well, depends on your snapclient DAC output

source = pipe:///tmp/airplay.pipe?name=Airport&mode-read&sampleformat=44100:16:2

[http]
doc_root = /usr/share/snapserver/snapweb

2. Login to your target snapclient(s), and create your run file (I haven't figured out a working compose file for this yet): start.sh.txt
   EDIT: I would recommend keeping your container and snapclient name the same

3. Connect to your Snapserver device thru Spotify/reciever thru AirPlay and let the music stream on😎
