The topmost layer of the stack is the application source-code in /src. The PHP application is build with
Yii 2.0 Framework.
The building blocks of the application.
The application along with other services are run in containers, usually you have one container per service, but you can also scale PHP-FPM with a haproxy or run multiple workers off a CLI container.
Services are defined in docker-compose.yml they describe the stack components, such as the PHP application, databases,
caches or testing containers.
Stacks and their service definitions can have different flavours. You may need slightly different setups in testing, staging
and production environment. phd features as yaml-converter-command, which can create stack files from templates.
Docker is the container-engine in which all services and tools are run, this ensures a maximum of portability across platforms and environments.
