Compose Example With UPnP Support

Here's another compose example with support for UPnP via docker-gmrender-resurrect-snapcast.

services:
  snapcast:
    image: ghcr.io/mill1000/snapcast-server:latest
    container_name: snapcast-server
    restart: unless-stopped
    network_mode: host
    volumes:
      - <SNAPSERVER_CONFIG>:/etc/snapserver.conf
      - /var/run/avahi-daemon/socket:/var/run/avahi-daemon/socket
      - /var/run/dbus:/var/run/dbus
      - snapcast-pipes:/streams
  
  gmrender-resurrect:
    image: ghcr.io/mill1000/gmrender-resurrect-snapcast:latest
    container_name: gmrender-resurrect
    restart: unless-stopped
    network_mode: host
    environment:
      FRIENDLY_NAME: "Snapcast"
      OPTIONS: "--port 59595 --mime-filter audio --gstout-audiopipe 'audioresample ! audioconvert ! audio/x-raw,rate=44100,format=S16LE,channels=2 ! filesink location=/snapcast/gmrender-resurrect'"
    volumes:
      - snapcast-pipes:/snapcast

volumes:
  snapcast-pipes:

Add a UPnP stream to snapserver.conf.

source = pipe:///streams/gmrender-resurrect?name=UPnP

Optionally, use the included stream plugin snapcat-upnp to add metadata support.

source = pipe:///streams/gmrender-resurrect?name=UPnP&controlscript=/usr/local/bin/snapcast-upnp&controlscriptparams=http://127.0.0.1:59595/description.xml
