This is a repo that documents the various scripts I used to create a server that loops a different song every hour.

The architecture is simple; a single VM runs the icecast server that broadcasts audio, as well as a Liquidsoap server that serves the audio.

I deployed this on GCP with a compute engine and a separate persistent disk that stored the media. To hide the server password, I employed Google's Secrets Manager to safely store and retreive the password.

I made the following modifications to a default compute engine instance before running:

• Open port 8000 to allow clients to connect to icecast
• Grant the instance read access to the secrets manager through a separate service account on Google IAM
• Attach a separate disk to store the audio files on independent of the VM
• As a matter of preference, I used Ubuntu 18.04 LTS instead of the default container image provided by Google

In this repo, you'll see:

• A startup script to mount a disk to the instance and set the timezone
• An installation and startup script for the icecast server component
  • The script sets up logs files on my home directory
  • The script also overwrites the default password with the password from Secrets Manager
  • A copy of the default icecast configuration file for reference
• A Liquidsoap script that plays a different song each out
• An installation and startup script for Liquidsoap that starts liquidsoap in the background
