NAME¶

cloudflare-ddns — dynamically update a DNS record

SYNOPSIS¶

DESCRIPTION¶

cloudflare-ddns is a tool that can be used to dynamically update a DNS record using Cloudflare's API.

This tool is a oneshot program: you run it, it updates the DNS record, and it terminates. To make it run periodically you could use a systemd timer or a cron job.

To run the tool you'll need an API token; cloudflare-ddns only needs the Zone.DNS edit permission.

You can run cloudflare-ddns in two different ways: you can pass the API Token and the record name as command line arguments, or you can use the ini configuration file located in /etc/cloudflare-ddns/config.ini by passing no arguments at all. If you prefer, you can even use a configuration file in a custom location, using --config file.

EXIT STATUS¶

The cloudflare-ddns utility exits 0 on success, and >0 if an error occurs.

EXAMPLES¶

$ cloudflare-ddns
