cloudflare-ddns

This was a project designed to explore the Cloudflare API through their official Go Client.

This application updates a given domain name to the current machine's ip address with the use of the https://ipify.org service. Alternative ip address services may be used if it returns the ip address of the current machine in plain text by overriding the configuration option.

You can run this service in a cron job or a systemd timer, or once, up to you!
