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

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}

If you are running on Windows:

https://hub.docker.com/editions/community/docker-ce-desktop-windows

If you are running on Linux:

base=https://github.com/docker/machine/releases/download/v0.16.0 &&
curl -L $base/docker-machine-$(uname -s)-$(uname -m) >/tmp/docker-machine &&
sudo install /tmp/docker-machine /usr/local/bin/docker-machine

If you are running on Windows:

$ base=https://github.com/docker/machine/releases/download/v0.16.0 &&
  mkdir -p "$HOME/bin" &&
  curl -L $base/docker-machine-Windows-x86_64.exe > "$HOME/bin/docker-machine.exe" &&
  chmod +x "$HOME/bin/docker-machine.exe"

If you are running on Linux:

sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && sudo chmod +x /usr/local/bin/docker-compose

If you are running on Windows: Docker for Windows and Docker Toolbox already include Compose with other Docker apps, so most Windows users do not need to install Compose separately.

sudo apt-get install pwgen

wget https://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

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

   cp .env.dist .env

2. Build / run containers with (with and without detached mode)

   docker-compose build
   docker-compose up -d
   

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

   # UNIX only: get containers IP address and update host (replace IP according to your configuration) (on Windows, edit C:\Windows\System32\drivers\etc\hosts)
   $ 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 and for Windows read this (4th step).

4. Prepare Symfony app

   1. Create a new user

      docker-compose exec mysql bash
      mysql -u root -p
      
      mysql> use mysql;
      mysql> CREATE USER 'db_user'@'mysql' IDENTIFIED BY 'db_password';
      mysql> GRANT ALL PRIVILEGES ON db_name.* TO 'db_user'@'mysql';
      mysql> FLUSH PRIVILEGES;
      

   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
      

      b) SF4: .env

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

   3. Composer install & create database

      $ docker-compose exec php bash
      $ composer create-project symfony/website-skeleton my-project
          
      # Symfony2
      $ sf doctrine:database:create
      $ sf doctrine:schema:update --force
      # Only if you have `doctrine/doctrine-fixtures-bundle` installed
      $ sf doctrine:fixtures:load --no-interaction
          
      # Symfony3
      $ sf3 doctrine:database:create
      $ sf3 doctrine:schema:update --force
      # Only if you have `doctrine/doctrine-fixtures-bundle` installed
      $ sf3 doctrine:fixtures:load --no-interaction
      
      # Symfony4
      $ sf4 doctrine:database:create
      $ sf4 doctrine:schema:update --force
      # Only if you have `doctrine/doctrine-fixtures-bundle` installed
      $ sf4 doctrine:fixtures:load --no-interaction

5. Enjoy :-)

   Usage

   Just run docker-compose up -d, then:

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

   Alternative option is to use prepared bash script:

   ./up.sh create and start containers

   ./down.sh stop and remove containers, networks, images, and volumes

   How it works?

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

   • mysql: This is the MySQL database container,
   • php: This is the PHP-FPM container in which the application volume is mounted,
   • nginx: This is the Nginx webserver container in which application volume is mounted too,

   This results in the following running containers:

   $ docker-compose ps
                 Name                             Command               State                    Ports
