Azure DDNS

This is a simple bash script that can be used as a cronjob to use Azure DNS for your dynamic DNS. If you have a low traffic domain, this is much cheaper than any bespoke DDNS service. Can be run on a Raspberry Pi, Mac, or any other single computer on your network with cron and bash/zsh/sh.

Setup

1. You need to have the Azure CLI installed on your system. Then login to the Azure CLI.
2. Adapt the variables in the scripts to include your domain, zone, and resource group.
3. Schedule the scripts via cron.
4. Enjoy your extremely cheap DDNS.
