We need to create a .env file with this variables:
MYSQL_ROOT_PASSWORD=root
MYSQL_DATABASE=project
Create the containers
docker-compose build
Start the containers
docker-compose up -d
Optional: Check if everything is installed properly, not required
docker-compose exec app composer require symfony/requirements-checker
docker-compose exec app php ./vendor/bin/requirements-checker
docker-compose exec app composer remove symfony/requirements-checker
rm -rf ./www/*
Start a new project, this is going to install the basic files and structure
docker-compose exec app composer create-project symfony/website-skeleton ./
docker-compose exec app composer require server --dev
Start the dev server
docker-compose exec app php bin/console server:start 0.0.0.0:8000
Stop the dev server
docker-compose exec app php bin/console server:stop
Stop the containers
docker-compose stop
