The original goal was to create a simple Nodejs client that updates a Cloudflare DNS entry to the client's public IP, much like DDNS. The new goal is to create a Python equivalent offering a server mode mimicking the same response as Cloudflare's trace service.

Node client to updates DNS entry in Cloudflare

git clone https://github.com/jhfoo/cloudflare-ddns.git

npm start <host.domain.name> <cloudflare api token>

Create a token with the following permission:

• Zone -> DNS -> Edit

1. Check if zone is managed by the token.
2. Get IP as reported by Cloudflare trace tool.
3. Create/ update host.domain.name with IP.

git clone https://github.com/jhfoo/cloudflare-ddns.git
cd cloudflare-ddns/python
./bin/setup

cd cloudflare-ddns/python
./bin/cloudflare-ddns -h

cd cloudflare-ddns/python
./bin/cloudflare-ddns client <hostname> <api token>

Alternatively the API token can be read from the environment variable CLOUDFLARE_TOKEN. If token is passed in the CLI it supercedes the environment variable.

cd cloudflare-ddns/python
./bin/cloudflare-ddns server [<port>] [--dev|-d]

--dev runs server in development mode which means the server does not exit upon shutdown.

The following paths are valid:

/shutdown      # stops the service
/cdn-cgi/trace # mimicks the same path as Cloudflare
/              # same as above: for lazy people
