For Dynamic DNS update for domains registered via Godaddy using godaddy-dns node js package use following steps:

1. Create API key and secret through web browser
   1. Login to godaddy developer site using your godaddy credentials https://developer.godaddy.com/keys/
   2. Click on "API Keys"
      1. Select "Create New API Key in top right side"
      2. Enter Keyname "test-Rnd"
      3. Choose environment "Production"
      4. Click Next
      5. Save API key and secret. (It doesn't show secret again)
2. Install node.js

   curl -sL https://rpm.nodesource.com/setup_8.x | sudo bash -
   yum install -y nodejs

3. Check node.js version

   node --version
   npm --version

4. Install godaddy-dns using NPM

   npm install --global godaddy-dns

5. Check whether installation is successful

   godaddy-dns -V

6. Create script (config.json' for updating sub-domain IP using our dynamic public ip with:

   {
   "apiKey": "<paste-api-key>",
   "secret": "<paste-api-secret>",
   "domain": "example.com",
   "records": [
   {"type": "A", "name": "mysubdomain", "ttl": 600}
   ]
   }

   Above script will update "mysubdomain.example.com" record every time new public IP is detected

7. Run script using:

   godaddy-dns -c config.json

   You will get output like below
