How to install Hashicorp Nomad on aarch64 Alpine Linux (Moto G6 / PostmarketOS)

Since as of now there is no binary release for Hashicorp Nomad in aarch64, we'll have to compile it from scratch.

PostmarketOS configuration

play-audio-mic.sh

This script was adapted to allow you to play audio files through your microphone input. It does so by creating a virtual microphone and piping an audio file to it.

The work was mostly done in this StackOverflow answer, I just adapted it to use ffmpeg and add a trap to cleanup on exit.

Requirements:

• ffmpeg
• Bash
• PulseAudio/pactl

This is an example workaround for getting Terraform input variables when you won't have jq available in the executing machine.

Uses sed to parse the input JSON to extract a certain key from the input JSON.

Warning: this hasn't really been well-tested, it will pretty much work only with string values and will likely break for strings that have quotes. Might give you an idea of how to improve it for your implementation though.
