This is the simplest way to run Symfony5 without modifying your local machine environment to develop your new Symfony5 project.

• Docker

• nginx 1.18.+
• php-fpm 7.4.+
  • composer
  • yarn and node.js (if you will use Encore for managing JS and CSS)
• mysql 5.7.+

run docker and connect to container:

 docker-compose up --build

 docker-compose exec php sh

install latest version of Symfony via composer:

# traditional web application: 
$ composer create-project symfony/website-skeleton .

or

# microservice, console application or API:
$ composer create-project symfony/skeleton .

modify your DATABASE_URL config in .env

DATABASE_URL=mysql://root:root@mysql:3306/symfony?serverVersion=5.7

call localhost in your browser
