Dynamic DNS | GoDaddy

What is this application?

This application will take the current Hostnames (subdomain) in the machine and the configuration file for the tld and make sure the subdomain matches to the IP provided

Run this application as a system service, It will automatically run the update every hour on the dot.

Example:

If machine name is awesome.machine.local Top Level Domain is example.com Public IP address is 123.456.789.123

This will update the TLD Address record to a FQDN to the machines public IP address Output would be awesome.example.com ==> 123.456.789.123

Setup

Make a copy of the example.com.env file and rename it to your TLD but keep the .env at the end!

Edit the config file to your liking, Check below for what each setting does

Make sure you have node/npm installed on your system, Don't forget to run npm i

Config keys/settings and their meanings

TLD is your top level domain, I recommend settings this to the file name of your config '.env' file.

USE_HOSTNAME is a boolean string. Do you want the program to use the first subdomain of your machines hostname? or just set the direct @ address for the A record on GoDaddys DNS settings.

GODADDY_API_ENDPOINT is the endpoint of GoDaddys API, Keep this the same unless GoDaddy changes this.

GODADDY_KEY The key from your GoDaddy API

GODADDY_SECRET The Secret from your GoDaddy API

How do I run this automatic script as a System Service?

I'm using systemd on my Linux system, You can do what ever you want though. Just make sure you run the execution script with your tld settings!
