eb_deployer

Automates the entire blue-green deployment workflow on Elastic Beanstalk, creating duplicate stacks and switching traffic after smoke tests, as outlined in the usage steps.

Supports custom smoke tests using curl or Rake tasks, allowing validation of deployments before cutover to ensure reliability, as demonstrated in the configuration examples.

Uses YAML files with ERB templating for deployment settings, enabling version control and flexible configuration, similar to Rails database.yml files.

Facilitates sharing of AWS resources like RDS between blue-green environments, simplifying resource management without manual intervention.
