docker-symfony

Build Status

Just a little Docker POC in order to have a complete stack for running Symfony into Docker containers using docker-compose tool.

Installation

First, clone this repository:

$ git clone [email protected]:eko/docker-symfony.git

Add symfony.dev in your /etc/hosts file.

Either put your Symfony application into symfony folder or add .env to your symfony project with following content

COMPOSE_FILE=../docker-symfony/docker-compose.yml
COMPOSE_PROJECT_NAME=PROJECT_NAME
LOG_PATH=../PROJECT_NAME/logs
SRC_PATH=../PROJECT_NAME/src
XDEBUG_IP_ADDRESS=

Make sure you adjust database_host in parameters.yml to the database container alias "db"

Then, run:

$ docker-compose up

You are done, you can visit your Symfony application on the following URL: http://symfony.dev (and access Kibana on http://symfony.dev:81)

Note : you can rebuild all Docker images by running:

$ docker-compose build

How it works?

Here are the docker-compose built images:

  • db: This is the MySQL database container (can be changed to postgresql or whatever in docker-compose.yml file),
  • php: This is the PHP-FPM container including the application volume mounted on,
  • nginx: This is the Nginx webserver container in which php volumes are mounted too,
  • elk: This is a ELK stack container which uses Logstash to collect logs, send them into Elasticsearch and visualize them with Kibana.

This results in the following running containers:

> $ docker-compose ps
        Name                      Command               State              Ports
        -------------------------------------------------------------------------------------------
        docker_db_1            /entrypoint.sh mysqld            Up      0.0.0.0:3306->3306/tcp
        docker_elk_1           /usr/bin/supervisord -n -c ...   Up      0.0.0.0:81->80/tcp
        docker_nginx_1         nginx                            Up      443/tcp, 0.0.0.0:80->80/tcp
        docker_php_1           php5-fpm -F                      Up      9001/tcp

Development

Attach to php container to call compose or symfony.

$ docker-compose exec php /bin/sh

XDebug

  • Set local ip in .env, e.g. XDEBUG_IP_ADDRESS=10.0.75.1 in .env (on windows/mac use VM IP)
  • In your IDE set XDebug listen port to 9030. Depending on IDE set IP.
  • Use XDebug Helper or similar to start debugging session

Read logs

You can access Nginx and Symfony application logs in the following directories on your host machine:

  • logs/nginx
  • logs/symfony

Use Kibana!

You can also use Kibana to visualize Nginx & Symfony logs by visiting http://symfony.dev:81.
