Setup Symfony 4.3.1 with Docker

Setup

Follow this procedure in order to have a Symfony project with the version 4.3.1 and the local environment setup (with Docker).

1. Clone the repository: git clone https://github.com/rfaivre/symfony4-training.git
2. Launch the docker: docker-compose up -d
   • if you have some issues with the permissions of the var directory, please run:
     1. chmod -R 755 var
     2. change the owner of the db directory: sudo chown -R 999:root var/db
     3. Once done, relaunch docker-compose up -d
   • normally, the composer install command is launched.
3. Reach the url https://site.training.docker
4. If everything works, you must have a page explaining that the Symfony application is now ready.

Quick Tour

• Symfony flex is installed. It allows to install and automate the installation and the setup of bundles and other Composer dependencies.

Quick explanation of the structure:

• bin: contains the executable (for example the symfony console or phpunit)
• config: contains all configuration of the application and other dependencies.
• public: web files like images,
• src: all your logic must be here.
• templates: contains all your templates
• tests: write your tests here
• var: temporary files
• vendor: composer dependencies and bundles

Useful tips

• Run command inside the docker: docker-compose exec web bash. Once connected, you can reach the symfony console.
• If you want override some environment variable, specific to your local, please create a file .env.dev.local (this file will not be committed). For example, if you want override the database configuration.
• The symfony console is very useful. It can be used by typing: php bin/console
• Run unit tests: php bin/phpunit
• If you use PHPStorm, please install the Symfony plugin for PHPStorm
