Docker Cloudfare DDNS

Simple Docker image that wraps an example script to dynamically update a Cloudflare DNS record.

Usage

There are two things to configure. First, the domain that you wish to update needs to be provided as a command line argument. This can be done by adding it to the end of your run command (example in the Makefile) or by adding it as a command to your compose file. Eg:

ddns:
  image: IamTheFij/cloudflare-ddns
  command: ["example.com"]

Your Cloudflare credentials can be passed in any way that python-cloudflare allows. Generally, either via envioronment variables:

CF_API_EMAIL=admin@example.com  # Do not set if using an API Token
CF_API_KEY=00000000000000000000
CF_API_CERTKEY='v1.0-...'

Or by providing a file mounted to the working directory in the image, /src/.cloudflare.cfg that contains something like:

[CloudFlare]
emal = admin@example.com  # Do not set if using an API Token
token = 00000000000000000000
certtoken = v1.0-...

Then run. To execute from this directory, you can use the convenient Make target.

make run
