Docker for Symfony (PHP-FPM - NGINX - MySQL)

Docker symfony gives you everything you need for developing Symfony application. This complete stack run with docker and docker-compose.

Installation

Install the latest Docker CE version

If you are running on Linux:

curl -fsSL https://get.docker.com -o get-docker.sh &&
sh get-docker.sh

If you would like to use Docker as a non-root user, you should now consider adding your user to the "docker" group with something like:

sudo usermod -aG docker ${USER}

Install the latest Docker Compose

If you are running on Linux:

sudo curl -L "https://github.com/docker/compose/releases/download/v2.6.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && sudo chmod +x /usr/local/bin/docker-compose

Install PWGen

Debian / Ubuntu

sudo apt-get install pwgen

CentOS

wget http://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/p/pwgen-2.08-1.el7.x86_64.rpm && rpm -ivh pwgen-2.08-1.el7.x86_64.rpm

Configuration

1. Create a .env from the .env.dist file. Adapt it according to your symfony application

   cp .env.dist .env
   

2. Build / run containers

   ./d4d start
   

3. Update your system host file (add symfony.local)

   # UNIX only: get containers IP address and update host (replace IP according to your configuration)
   $ sudo echo $(docker network inspect bridge | grep Gateway | grep -o -E '[0-9\.]+') "symfony.local" >> /etc/hosts
   

   Note: For OS X, please take a look here.

4. Prepare Symfony app

   1. Get your logins to access MySQL server ./d4d passwd show

   2. Update

      a) SF2, SF3: app/config/parameters.yml

      # ./project/app/config/parameters.yml
      parameters:
          database_host:     mysql
          database_port:     ~
          database_name:     db_name
          database_user:     db_user
          database_password: db_password (random password)
      

      b) SF4, SF5, SF6: .env

      DATABASE_URL=mysql://db_user:db_password@mysql:3306/db_name
      MAILER_URL=smtp://mailhog:1025
      

   3. Composer install & create database

      $ docker-compose exec php bash
      $ composer create-project symfony/website-skeleton my-project
      
      # Symfony 2
      $ sf doctrine:database:create
      $ sf doctrine:schema:update --force
      # Only if you have `doctrine/doctrine-fixtures-bundle` installed
      $ sf doctrine:fixtures:load --no-interaction
      
      # Symfony 3
      $ sf3 doctrine:database:create
      $ sf3 doctrine:schema:update --force
      # Only if you have `doctrine/doctrine-fixtures-bundle` installed
      $ sf3 doctrine:fixtures:load --no-interaction
      
      # Symfony 4
      $ sf4 doctrine:database:create
      $ sf4 doctrine:schema:update --force
      # Only if you have `doctrine/doctrine-fixtures-bundle` installed
      $ sf4 doctrine:fixtures:load --no-interaction
      
      # Symfony 5
      $ sf5 doctrine:database:create
      $ sf5 doctrine:schema:update --force
      # Only if you have `doctrine/doctrine-fixtures-bundle` installed
      $ sf5 doctrine:fixtures:load --no-interaction
      
      # Symfony 6
      $ sf6 doctrine:database:create
      $ sf6 doctrine:schema:update --force
      # Only if you have `doctrine/doctrine-fixtures-bundle` installed
      $ sf6 doctrine:fixtures:load --no-interaction
      

5. Enjoy :-)

   Usage

   Just run ./d4d start, then:

   • Symfony app: visit symfony.local
   • Symfony dev mode: visit symfony.local/app_dev.php
   • Logs (files location): logs/nginx and logs/symfony

   How it works?

   Have a look at the docker-compose.yml file, here are the docker-compose built images:

   • nginx: Nginx is one of the most popular web servers in the world and responsible for hosting some of the largest and highest-traffic sites on the internet. It is more resource-friendly than Apache in most cases and can be used as a web server or reverse proxy.
   • php: PHP is a popular general-purpose scripting language that is especially suited to web development.
   • mysql: MySQL is the most popular relational database management system.
   • phpmyadmin: phpMyAdmin was created so that users can interact with MySQL / MariaDB through a web interface.
   • mailhog: MailHog is an email testing tool for developers.
   • redis: Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes with radius queries and streams. Redis has built-in replication, Lua scripting, LRU eviction, transactions and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster.

   This results in the following running containers:

   $ docker-compose ps
              Name                          Command               State                       Ports
