Overview

This checks for changes to your public facing IP address (in line with the TTL specified) and updates a single record in AWS to point back at it.

Requirements

You'll need a Hosted Zone in Amazon Route53, and an IAM user who's allowed to write updates to it - their AWS Key and Secret.

Parameters

These can either be set as Environment Variables or passed as command line options..

• AWS_ID Your AWS ID
• AWS_SECRET Your AWS Secret
• AWS_REGION The AWS Region (eg EU_WEST_1)
• TTL Is the TTL that will be sent to the DNS Provider, this is also used to set the retry rate for checking your IP
• ROUTE53_ID Is the ID of the Hosted Zone where your record lives
• ROUTE53_RECORD Is the record to update - eg *.mydomain.com

eg $ node index.js --AWS_ID=yourAWSId --AWS_SECRET=asdfasdfasdfasdf --AWS_REGION=eu-west-1 --ROUTE53_ID=ROUTE53ZONEID --ROUTE53_RECORD=*.mydomain.co.uk --TTL=300
