cf-dyn-dns

This is a small project that updates a Cloudflare DNS record with the current public IP address of the machine it is running on.

It should run frequently, probably with a service system like systemd, for which a unit file is provided.

Setup

Follow these steps

git clone https://github.com/t-mart/cf-dyn-dns.git
cd cf-dyn-dns
deno cf-dyn-dns

Running as a systemd service

1. Add the service and timer files to the systemd directory:

   sudo cp cf-dyn-dns.service /etc/systemd/system/
   sudo cp cf-dyn-dns.timer /etc/systemd/system/

2. Review the cf-dyn-dns.service file and make changes as appropriate.

3. Copy .env.template to .env and fill in the required values.

4. Enable and start the service:

   sudo systemctl enable cf-dyn-dns.service
   sudo systemctl enable cf-dyn-dns.timer
   sudo systemctl start cf-dyn-dns.service
   sudo systemctl start cf-dyn-dns.timer

   and check the status and the logs:

   sudo systemctl status cf-dyn-dns
   journalctl -u cf-dyn-dns
