cloudflare-ddns-updater

This is a simple script to update dynamic DNS records through cloudflare. It’s provided in case anyone finds it useful.

To use it you have to have an account with cloudflare and use them as your DNS provider. The script is written in node.js and tested with node.js 7.4 on MacOS Sierra and Ubuntu 16.10.

Setup and configuration

First clone the repository to somewhere on your system:

$ git clone https://github.com/tfmalt/cloudflare-ddns-updater.git
$ cd cloudflare-ddns-updater

Copy the file config_example.json to config.json and edit it to suit your needs:

$ cp config_example.json config.json
$ vim config.json

You will find your API key and your zone id in the Overview page of your cloudflare account.

{
  "api": {
    "key": "<your cloudflare api key>",
    "email": "[email protected]",
    "zones": "<the cloudflare zone you want to update>"
  },
  "hosts": {
    "ssh.example.org": {
      "types": ["A", "AAAA"]
    },
    "vpn.example.org": {
      "types": ["A", "AAAA"]
    }
  }
}

Install

Make sure the configuration is valid and then you can install the script globally to make it easy to use:

$ npm install . -g
