Key concepts

Template and parameter pairing

The starter kit pairs templates with parameters by filename:

  • templates/oidc-provider.yml → parameters/test/oidc-provider.yml
  • templates/network.yml → parameters/production/network.yml

Environment isolation

Each environment has:

  • Dedicated parameter folder under parameters/<env>/
  • GitHub variable for account ID (<ENV>_AWS_ACCOUNT_ID)
  • Separate workflow for deployment

Automated validation

GitHub Actions workflows provide:

  • Template validation with cfn-lint
  • Security scanning with Checkov
  • Rain deployments on merge to main
