PHPCon 2024 - Demystify Dependency Injection - Understanding the magic of the Container

Requirements

• PHP 8.3
• Composer

Optional requirements

• Symfony CLI Tool
• Docker Engine
• Docker Compose

Getting started

1. Make sure you have recent versions of Docker and Docker Compose installed.
2. Clone this repository.
3. Build and run the stack by calling docker-compose up -d --build.
4. To execute PHP, call docker-compose exec dev bash first, which will open a shell within the dev container. There PHP is available as usual.

Composer and Symfony

Both Composer and the Symfony CLI are preinstalled and can be called anywhere within the container via composer and symfony.

Be aware that Docker-related features of the Symfony CLI do not work as expected, as it can't access the Docker infrastructure.

Tip

If you have installed make, you can use the commands provided in the Makefile.
