Description

• This is a tool to update a route53 domain using a local script, AWS Kinesis and AWS Lambda
  • A specified A-Record will be updated
  • The record must exist beforehand
• There are 3 main components
  • (1) An AWS Lambda function that modifies/updates an AWS Route53 domain/zone
    • The Route53 zone must already exist and be hosted in Route53
    • The Route53 zone is expected to have at least 1 A-Record
    • The A-Record should be a root (eg '*.domain.com' or 'domain.com')
  • (2) An AWS Kinesis stream that publishes an event to (1) an AWS Lambda function
  • (3) A Local Python App which checks current public IP and publishes a JSON payload to (2) an AWS Kinesis Stream
    • Python App can be run manually in Python
    • Python App can be run as a Docker container
    • Python App can be run as a Kubernetes Helm Chart
