Route53 Dynamic DNS Updater

This uses the sjmayotte/route53-dynamic-dns Docker image and utility to maintain DNS records for my home's dynamic IP address.

Usage

Refer to the upstream project for detailed usage documentation.

The container expects a .env file to be provided with environment variables. I've provided .env.example for a reference. The utility relies on an AWS access key with minimal rights to the Route53 zone. These are maintained in the Terraform codebase that manages the jbeard.dev AWS resources, including Route53.

Once a .env file is configured, simply start the service with docker-compose:

docker-compose up

Configuration

The configuration uses environment variables.

For deployments on my homelab, the GitLab CI/CD vars are used for specifying configurations.

These are protected file variables.

Refer to the .env.example.
