Docker stack for Symfony projects

For a more complete version visit: Docker-for-Symfony

Basic info

• nginx
• PHP-FPM
• MySQL
• PHPMyAdmin

Previous requirements

This stack needs docker and docker-compose to be installed.

Installation

1. Create a .env file from .env.dist and adapt it according to the needs of the application

   $ cp .env.dist .env && nano .env

2. Build/run containers in detached mode (stop any local nginx/apache/mysql service)

   $ docker-compose build
   $ docker-compose up -d

3. Get the bridge IP address

   $ docker network inspect bridge | grep Gateway | grep -o -E '[0-9\.]+'
   # OR an alternative command
   $ ifconfig docker0 | awk '/inet:/{ print substr($2,6); exit }'

4. Update your system's hosts file with the IP retrieved in step 3.

   $ sudo nano /etc/hosts

5. Prepare the Symfony application

   1. Update Symfony parameters (.env file)

      #...
      DATABASE_URL=mysql://user:userpass@mysql:3306/mydb
      #...
      

   2. Composer install & update the schema from the container

      $ docker-compose exec php bash
      $ composer install
      $ symfony doctrine:schema:update --force

6. (Optional) Xdebug: Configure your IDE to connect to port 9001 with key PHPSTORM

How does it work?

We have the following docker-compose built images:

• nginx: The Nginx webserver container in which the application volume is mounted.
• php: The PHP-FPM container in which the application volume is mounted too.
• mysql: The MySQL database container.
• phpmyadmin: The PHPMyAdmin server/administration container.

Running docker-compose ps should result in the following running containers:

           Name                          Command               State              Ports
--------------------------------------------------------------------------------------------------
container_mysql         /entrypoint.sh mysqld            Up      0.0.0.0:3306->3306/tcp
container_nginx         nginx                            Up      443/tcp, 0.0.0.0:80->80/tcp
container_phpfpm        php-fpm                          Up      0.0.0.0:9000->9000/tcp
container_phpmyadmin    /run.sh phpmyadmin               Up      0.0.0.0:8080->80/tcp

Usage

Once all the containers are up, our services are available at:

• Symfony app: http://symfony.dev:80
• MySQL server: symfony.dev:3306
• PHPMyAdmin: http://symfony.dev:8080
• Log files location: logs/nginx and logs/symfony

🎉 Now we can stop our stack with docker-compose down and start it again with docker-compose up -d.
