Sustainer 2.0

This is a new version of the sustainer system which uses liquidsoap. This uses the API interface from Digiplay Laravel so that we never directly talk to the database.

Installation (developer environment) instructions

1. Make sure you have liquidsoap installed
2. git clone https://github.com/radiowarwick/sustainer.git
3. cd sustainer
4. cp sutainer.config.example sustainer.config
5. Fill sustainer.config with configuration values
6. Run using liquidsoap sustainer.liq

Installing in production (liqudsoap dameon)

If you would like to install the sustainer to be run using liquidsoap's built in daemon then you'll need to do the following.

ln -s $(pwd)/sustainer.liq /etc/liquidsoap/sustainer.liq
ln -s $(pwd)/sustainer.config /etc/liquidsoap/sustainer.config
systemctl restart liquidsoap

Installing in production (docker)

The Sustainer is run through a docker container, and allows you to have phyiscal output via ALSA, as well as sending the audio to an icecast server.

First make a copy of config.liq.example and fill it in with your config information. (API key, Icecast information, weightings, etc.)

The most basic execution of the container is as follows: docker run --device /dev/snd -v /mnt/dps0-0:/mnt/dps0-0:ro -v /path/to/my/config.liq:/sustainer/config.liq -v /var/sustainer.log:/var/log/liquidsoap/sustainer.log raw1251am/sustainer

--device /dev/snd This gives the container access to the host's sound device.

-v /mnt/dps0-0:/mnt/dps0-0 Mounts the audio file system, change left hand side if your audio is mounted in a different location.

-v /path/to/my/config.liq:/sustainer/config.liq This maps your config file for the sustainer to use. Change left hand path to map to your config file

-v /var/sustainer.log:/var/log/liquidsoap/sustainer.log maps the log file out of the container, change left hand side to your log location
