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

Credit: this is a kind of fork from eko/docker-symfony. Thanks to him :-)

Installation

1. Retrieve git project

   $ git clone git@github.com:maxpou/docker-symfony.git

2. Move your Symfony project into symfony folder

3. Build containers with (with and without detached mode)

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

4. Update your host file (add symfony.dev)

   # get containers IP address and update host (replace IP according to your configuration)
   $ docker inspect --format '{{ .NetworkSettings.IPAddress }}' $(docker ps -f name=nginx -q)
   $ sudo echo "171.17.0.1 symfony.dev" >> /etc/hosts

5. Prepare Symfony app

   1. Retrieve DB&Redis IP

      $ docker inspect --format '{{ .NetworkSettings.IPAddress }}' $(docker ps -f name=db -q)
      $ docker inspect --format '{{ .NetworkSettings.IPAddress }}' $(docker ps -f name=redis -q)

   2. Update app/paraeters.yml (adapt hosts according to previous results)

      parameters:
          database_host: 172.17.0.4
          database_port: null
          database_name: symfony
          database_user: root
          database_password: root
          redis_host: 172.17.0.3

   3. Composer install

      $ docker exec -ti $(docker ps -f name=php -q) sh -c  "cd /var/www/symfony/ && composer install"

6. Enjoy :-)

Using

• Symfony app: visit symfony.dev
• Symfony dev mode: visit symfony.dev/app_dev.php
• Logs (Kibana): symfony.dev:81
• 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:

• application: This is the Symfony application code container,
• 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,
• redis: This is a redis database container.

This results in the following running containers:

$ docker-compose ps
           Name                          Command               State              Ports

FAQ

• Got this error: ERROR: Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running? If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable. ?
  Run docker-compose up -d instead.

• Permission problem? See this doc (Setting up Permission)

TODO

• Upgrade ELK stack. Install Timelion <3
• MySQL -> PostgreSQL
• Move SF app folder?
• use php7-fpm/php.ini
