cfdydns

Cloudflare dynamic DNS client

A simplistic dynamic DNS client that only works with Cloudflare, for only one domain. It's easily configurable via environment variables, making it an ideal choice to use in containers.

Installation

The recommended way of using cfdydns is through containers. Built containers are available in:

GitHub Container Registry: ghcr.io/xjonathanlei/cfdydns:latest
Docker Hub: xjonathanlei/cfdydns:latest

You may also install the binary directly. With the Rust toolchain installed:

cargo install --locked --path .

Getting started

cfdydns is configurable via command line options and environment variables. Running cfdydns --help reveals the options:

Option	Env var	Optional	Description
`--fqdn`	`CFDYDNS_FQDN`	No	Fully-qualified domain name to set A record on
`--zone`	`CFDYDNS_ZONE`	No	Zone name of the FQDN (e.g. `example.com`)
`--api-token`	`CFDYDNS_API_TOKEN`	No	Cloudflare API token with the `DNS: Edit` permission for the target zone
`--interval`	`CFDYDNS_INTERVAL`	Yes	Number of seconds to wait between each check

[!TIP]

cfdydns does not create new records for you. The target A record for the FQDN must already exist.

Why not ddclient?

ddclient is hard to configure and barely maintained. Who cares about all the DNS provider integration when you're only using Cloudflare anyways.
