The files in this directory provide the configuration for application {{{APPLICATION}}} in environment {{{ENVIRONMENT}}}. The SETENV file provides a single location for configuration variables. In the current implementation, the Volumes and Scripts directories get mounted into the running Docker containers via a rather convoluted path. Here -> secure CodeCommit repo -> Downloaded in CodePipeline 'Source' Stage -> Merged with source code in CodePipeline 'Merge' Stage -> Config installed to /SecureConfig in Docker container during CodePipeline 'Build' Stage -> Deploy.zip extracted in CodePipeline 'Extract' stage -> Deploy.zip provides template used by CloudFormation in CodePipeline 'Deploy' stage In that final stage, the Docker image is deployed as a service into ECS. Deploy/service.cf is a Cloudformation script to configure the application as an ECS service. For repeat builds, the same definition is rerun to update the service to use the new Docker image.
