Docker Symfony 4 (PHP7-FPM - NGINX - MySQL - ELK)

Docker-symfony gives you everything you need for developing Symfony 4 application. This complete stack run with docker and docker-compose (1.7 or higher).

Installation

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.localhost) Remember that server name is define in .env file in this demo I use symfony.localhost please replace with your custom server name if you decide to use another one

   # 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.localhost" >> /etc/hosts

   Note: For OS X, please take a look here and for Windows read this (4th step).

4. Prepare Symfony app

   1. Update app/config/parameters.yml

      # path/to/your/symfony-project/app/config/parameters.yml
      parameters:
          database_host: db

   2. Composer install & create database

      $ docker-compose exec php bash
      $ composer install
      $ sf doctrine:database:create
      $ sf doctrine:schema:update --force
      # Only if you have `doctrine/doctrine-fixtures-bundle` installed
      $ sf doctrine:fixtures:load --no-interaction

5. Enjoy :-)

Usage

Just run docker-compose up -d, then:

• Symfony app: visit symfony.localhost
• Symfony dev mode: set APP_ENV=dev and rebuild
• Symfony test mode: set APP_ENV=test and rebuild
• Symfony prod mode: set APP_ENV=prod and rebuild
• Logs (Kibana): symfony.localhost:81
• Logs (files location): logs/nginx and logs/symfony
• Mailcatcher: visit symfony.localhost:1080

Customize

If you want to add optionnals containers like Redis, PHPMyAdmin... take a look on doc/custom.md.

How it works?

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

• db: 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,
• elk: This is a ELK stack container which uses Logstash to collect logs, send them into Elasticsearch and visualize them with Kibana.
• mailcatcher: This is a Mailcatcher container for email testing.

This results in the following running containers:

$ docker-compose ps
           Name                          Command               State              Ports            
--------------------------------------------------------------------------------------------------
dockersymfony_db_1            /entrypoint.sh mysqld            Up      0.0.0.0:3306->3306/tcp      
dockersymfony_elk_1           /usr/bin/supervisord -n -c ...   Up      0.0.0.0:81->80/tcp          
dockersymfony_nginx_1         nginx                            Up      443/tcp, 0.0.0.0:80->80/tcp
dockersymfony_php_1           php-fpm                          Up      0.0.0.0:9000->9000/tcp
dockersymfony_mailcatcher_1   /run.sh                          Up      0.0.0.0:1025->1025/tcp, 0.0.0.0:1080->1080/tcp   
      

Useful commands

# bash commands
$ docker-compose exec php bash

# Composer (e.g. composer update)
$ docker-compose exec php composer update

# SF commands (Tips: there is an alias inside php container)
$ docker-compose exec php php /var/www/symfony/bin/console cache:clear 
# Same command by using alias
$ docker-compose exec php bash
$ sf cache:clear

# Retrieve an IP Address (here for the nginx container)
$ docker inspect --format '{{ .NetworkSettings.Networks.dockersymfony_default.IPAddress }}' $(docker ps -f name=nginx -q)
$ docker inspect $(docker ps -f name=nginx -q) | grep IPAddress

# MySQL commands
$ docker-compose exec db mysql -uroot -p"root"

# Check CPU consumption
$ docker stats $(docker inspect -f "{{ .Name }}" $(docker ps -q))

# Delete all containers
$ docker rm $(docker ps -aq)

# Delete all images
$ docker rmi $(docker images -q)

Debug your app

• How to config Xdebug? Xdebug is configured out of the box! Just config your IDE to connect port 9001 and id key PHPSTORM
