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

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

Installation

1. In the docker-compose file, indicate where's your Symfony project

   services:
       php:
           volumes:
               - path/to/your/symfony-project:/var/www/symfony

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

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

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

   # get containers IP address and update host (replace IP according to your configuration)
   docker inspect --format '{{ .NetworkSettings.IPAddress }}' $(docker ps -f name=nginx -q)
   # or, if empty :
   docker inspect $(docker ps -f name=nginx -q) | grep IPAddress
   # unix only (on Windows, edit C:\Windows\System32\drivers\etc\hosts)
   sudo echo "171.17.0.1 symfony.sf" >> /etc/hosts
   # on MAC with Docker for Mac, 127.0.0.1 can be used
   sudo echo "127.0.0.1 symfony.sf" >> /etc/hosts

4. Prepare Symfony app

   1. Retrieve mysql & redis IP

      docker inspect --format '{{ .NetworkSettings.Networks.dockersymfony_default.IPAddress }}' $(docker ps -f name=db -q)
      docker inspect --format '{{ .NetworkSettings.Networks.dockersymfony_default.IPAddress }}' $(docker ps -f name=redis -q)
      # or, if empty :
      docker inspect $(docker ps -f name=db -q) | grep IPAddress

   2. Update app/config/parameters.yml

      # path/to/your/symfony-project/app/config/parameters.yml
      parameters:
          database_host: mysqldb
          database_password: root
          #...
          redis_host: redis

   3. Composer install & create database

      docker-compose exec php bash
      composer install
      # Symfony2
      sf2 doctrine:database:create
      sf2 doctrine:schema:update --force
      sf2 doctrine:fixtures:load --no-interaction
      # Symfony3
      sf doctrine:database:create
      sf doctrine:schema:update --force
      sf doctrine:fixtures:load --no-interaction

Usage

Just run docker-compose -d, then:

• Symfony app: visit symfony.sf
• Symfony app through Varnish: visit symfony.sf:81
• Symfony dev mode: visit symfony.sf/app_dev.php
• Logs (Kibana): symfony.sf:8081
• Logs (files location): logs/nginx and logs/symfony
• PHPMyAdmin : symfony.sf:8080

Multiple applications running on this stack for a Service Oriented Architecture (SOA) application

If you want to use this docker configuration to run multiple Symfony applications - ex : project{1,2,3} - follow those steps :

• add the needed hosts to your local /etc/hosts

127.0.0.1   localhost symfony.sf project1.sf project2.sf project3.sf

• mount the volumes into docker-compose.yml

php:
    build: php7-fpm
    ports:
        - 9000:9000
    links:
        - db:mysqldb
        - redis
    volumes:
        - ../project1:/var/www/symfony_project1
        - ../project2:/var/www/symfony_project2
        - ../project3:/var/www/symfony_project3
        - ./logs/symfony:/var/www/symfony/app/logs
nginx:
    (...)

No need to modify nginx/symfony.conf as a wildcard is set to map automaticaly a subdomain with this pattern, example : project1.sf or project3.sf.

run docker-compose -d (alias dkup)

For OPcache & PHP FPM you can read the Symfony documentation for NGINX, more details here : OPcache Symfony symlinks issue for a Capifony deployment.

Then you can configure the VCL to fetch the right backend for each project eg. project2.sf:81 or project3.sf:81.

Add Couchdb :

To add CouchDB to this stack, add to docker-compose.yml :

couchdb:
image: couchdb
ports:
    - 8082:5984

To verify the exposed port :

docker inspect dockersymfony_couchdb_1

result :

"PortBindings": {
    "5984/tcp": [
        {
            "HostIp": "",
            "HostPort": "8082"
        }
    ]
},

Urls for CouchDB : localhost:8082, localhost:8082/_utils/, localhost:8082/_utils/fauxton/

You can use Kinematic UI for Docker.

Docker aliases

Into ~/.bash_profile :

alias dk='docker-compose build && docker-compose up -d'
alias dkup='docker-compose up -d'
alias dkbuild='docker-compose build'
alias dks='docker ps'
alias dkrm='docker stop $(docker ps -a -q) && docker rm $(docker ps -a -q)'
alias dkd='docker-compose down'
alias dkp='lsof -i -n -P | grep com.doc'
alias dkin='docker-compose exec php bash'

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 (OPcache & optimized for Docker usage),
• 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.
• varnish: This is a varnish container (from the New York Times Newsroom Developers).

This results in the following running containers:

$ docker-compose ps
           Name                          Command               State              Ports

FAQ

• Docker for Mac issue : port is already allocated (without even running containers) : docker-compose down & restart docker and eventually check ports : lsof -i tcp:PORTNUMBER or lsof -i -n -P | grep com.doc docker/for-mac#205

• 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.
