Overview

This Docker Compose configuration allows you to run PHP 7.4 with nginx 1.18, PHP-FPM, MySQL 8.0.23, PostgreSQL 13.1, Composer and Symfony.

It exposes 4 services:

• nginx
• php-fpm
• mysql
• postgres

To know all extensions enabled for PHP you can run it using docker-compose up and visit: http://localhost/ and check the PHP info.

PHP has by default pdo_mysql, pdo_pgsql and Xdebug enabled.

The UUID extension for PostgreSQL has been added.

Nginx includes default basic configuration for Symfony 5.

Composer runs during boot to install the vendors. More info: https://getcomposer.org

Symfony command is available. More info: https://symfony.com/download

Prerequisites

You must have docker running on your computer. Follow the installation instructions from here:

https://docs.docker.com/desktop/

How to use it

Start docker compose

Checkout this repo or download it.

Just run docker-compose up

By default nginx will be available on http://localhost:80, PostgreSQL on http://localhost:5432 and MySQL on http://localhost:3306

Use nginx

You can run some nginx commands when needed, i.e.:

docker-compose exec nginx nginx -v

Use Composer

You can run composer commands, i.e.:

docker-compose run composer <composer-command>

docker-compose run composer -V

Use Symfony

You can run symfony commands, i.e.:

docker-compose exec php-fpm symfony <symfony-command>

For instance, you can check symfony requirements:

docker-compose exec php-fpm symfony check:req

Use PHP

You can run PHP commands, i.e.:

docker-compose exec php-fpm php -v

Use PostgreSQL

You can run postgres commands, i.e.:

docker-compose exec postgres postgres -V

And work with your DBs:

docker-compose exec postgres psql -d testdb -U myuser

Use MySQL

You can run mysql commands, i.e.:

docker-compose exec mysql mysql -V

And work with your DBs:

docker-compose exec mysql mysql -u root -pmyrootpassword

Configuration

Configuring volumes

By default when you run docker-compose up it's attaching the src/ folder as volume. It will be the folder used to serve the source code.

Check docker-compose.yml and change the volumes for nginx and php-fpm where you have your code.

You can change ./src/ under volumes: to any other folder in your system.

volumes:
  - ./src/:/var/www/

For instance:

volumes:
  - ../my-symfony-project/:/var/www/

Configuring DBs

The docker-compose.yml runs both MySQL and PostgreSQL but if you want to use only one you can comment the code out (or delete it) the DB you don't want to use in docker-compose.yml file.

The .env file contains the sensitive user & password information for connecting to the DBs.

Modify .env file default parameters according to your needs.

Configuring PHP

You can enable/disable any PHP directive just by editing these files:

./php-fpm/conf.d/php.ini or ./php-fpm/conf.d/xdebug.ini
