liquidcast

Relay a radio stream using Liquidsoap + Icecast in a Docker stack

Config

cp .env_example .env
nano .env

Name	Purpose
STREAM_HTTP_URL	HTTP URL of a radio stream.
ICECAST_MOUNT_MP3	Icecast mountpoint name. Should end with '.mp3'
ICECAST_PORT	Port number available on host to listen relayed stream / output icecast on liquidsoap (port 8000).

Replace these two environment values with the ones you want

Start

You should install Docker Compose before. Once installed, build and run the app with Compose

docker-compose up -d

If the terminal returns something like

Starting icecast_1    ... done
Starting liquidsoap_1 ... done

You can now listen the stream on your localpoint : localhost:${ICECAST_PORT}/${ICECAST_MOUNT_MP3}

Go further : use the stack for advanced features, with Liquidsoap script file

Example with ./yourscript.liq

stream = input.http(getenv("STREAM_HTTP_URL"))

## write what you want stream = ...

output.icecast(
     %mp3,
     host = getenv("ICECAST_HOST"),
     port = 8000,
     password = getenv("ICECAST_SOURCE_PASSWORD"), 
     mount = getenv("ICECAST_MOUNT_MP3"), 
     mksafe(stream)
)

1- docker-compose.yml : Add under liquidsoap --> volumes:

./yourscript.liq:/liquidsoap/yourscript.liq

2- docker-compose.yml : Change the liquidsoap command

command: liquidsoap -v --debug /liquidsoap/yourscript.liq
