Docker for Kreta

This complete stack run with docker and docker-compose (1.7 or higher).

It provides the following containers:

  • Nginx
  • MySQL
  • PHP7-FPM
  • RabbitMQ
  • Node

Installation

  1. Copy the file located at <kreta-root>/etc/docker/.env.dist to <kreta-root>/etc/docker/.env and change the values according to your needs.

  2. Update your system host file

    Add this line to /etc/hosts

    127.0.0.1 kreta.localhost taskmanager.localhost identityaccess.localhost

  3. Execute this command

    sh etc/bash/docker.sh [-f This optional flag load fixtures with fake data]

  4. Enjoy :-)

  • Symfony app: visit kreta.localhost. If you get 502 visit Known Issues at bottom

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,
  • rabbitmq: This is a rabbitmq container.
  • node: This is a the node container.

This results in the following running containers:

$ docker-compose ps
      Name                     Command               State                                             Ports
-------------------------------------------------------------------------------------------------------------------------------------------------------
docker_db_1         docker-entrypoint.sh mysqld      Up      0.0.0.0:3307->3306/tcp
docker_nginx_1      /bin/sh -c sh /var/www/ser ...   Up      443/tcp, 0.0.0.0:80->80/tcp
docker_node_1       /bin/sh -c sh /var/www/ser ...   Up      0.0.0.0:3000->3000/tcp
docker_php_1        docker-php-entrypoint php-fpm    Up      0.0.0.0:9000->9000/tcp
docker_rabbitmq_1   docker-entrypoint.sh rabbi ...   Up      15671/tcp, 0.0.0.0:15672->15672/tcp, 25672/tcp, 4369/tcp, 5671/tcp, 0.0.0.0:5672->5672/tcp

Useful commands

# bash commands
$ docker-compose exec php bash

# Symfony commands using aliases (from inside the php contanier)
$ docker-compose exec php bash
$ cd /var/www/taskmanager && sf cache:clear
$ cd /var/www/identityaccess && sf cache:clear

# 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)

Known issues

  • Database requires root connection to create multiple databases
  • Sometimes logs, cache and sessions cannot be written due to permission issues, change var folder permissions to 777
  • Node takes some time to up, if browser brings you 502 try again few minutes later
  • If you have some infrastructure installed locally (MySQL, RabbitMQ, WebServer...) you'll get an error indicating that port is already allocated

FAQ

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

  • I get "Error in Missing binding /var/www/compositeui/node_modules/node-sass/vendor/linux-x64-51/binding.node" Just run docker-compose exec node bash -c "npm rebuild node-sass If it does not work, delete node_module folder and run docker-compose exec node bash -c "npm install
