ices

IceS is a source client for the Icecast streaming server. The purpose of this client is to provide an audio stream to Icecast, so that one or more listeners can access the stream. With this layout, the source client can be situated remotely from the Icecast server.

How It Works

                +-> (LAN) -> (icecast) -+
(in) -> (ices) -|                       |-> (out) -> (mpd) -> (file)
                +-> (WAN) -> (icecast) -+

docker-compose.yml

version: "3.8"

services:

  ices:
    image: vimagick/ices
    volumes:
      - ./data:/etc/ices
    devices:
      - /dev/snd
    depends_on:
      - icecast
    restart: unless-stopped
  
  icecast:
    image: vimagick/icecast
    ports:
      - "8000:8000"
    restart: unless-stopped

You can setup multiple instances (e.g. LAN & WAN).
