Docker build and development environment

[ruflin]

Introduction of Docker as the build and development environment.

• Exchange of build.xml (ant) through Makefile
• Introduction of Docker-compose to setup the environment
• Configuration files for elasticsearch and nginx environment

I hope to use this in the future also for Travis / CI builds.

@im-denisenko Can you please have a look at this and also try it out locally (see commands in Makefile). You need docker-compose installed.

There are still 2 tests failing and socket_create is missing. I will fix the failing test issue now.

Every new command in Dockerfile will create new layer. It's ok, but minimize that number is good practice.

I would suggest combine them like following:

FROM composer/composer
ENV PATH=/root/composer/vendor/bin:$PATH
WORKDIR /app
COPY composer.json /app/

RUN apt-get update &&\
    apt-get upgrade -y &&\
    apt-get install -y nano &&\
    apt-get install -y cloc &&\
    apt-get install -y php5-xsl &&\
    apt-get install -y graphviz &&\
    apt-get install -y php5-xdebug &&\
    apt-get install -y php5-memcache

RUN echo "extension=/usr/lib/php5/20131226/xsl.so" >> /usr/local/etc/php/conf.d/xsl.ini &&\
    echo "zend_extension=/usr/lib/php5/20131226/xdebug.so" >> /usr/local/etc/php/conf.d/xdebug.ini &&\
    echo "extension=/usr/lib/php5/20131226/memcache.so" >> /usr/local/etc/php/conf.d/memcache.ini

RUN composer self-update &&\
    composer global require "phpunit/phpunit" &&\
    composer global require "pdepend/pdepend" &&\
    composer global require "phpmd/phpmd" &&\
    composer global require "mayflower/php-codebrowser" &&\
    composer global require "sebastian/phpcpd" &&\
    composer global require "squizlabs/php_codesniffer" &&\
    composer global require "phploc/phploc" &&\
    composer global require "fabpot/php-cs-fixer" &&\
    composer global require "phpdocumentor/template-zend" &&\
    composer global require "phpdocumentor/phpdocumentor" &&\
    composer require "guzzlehttp/guzzle" &&\
    composer install

@im-denisenko Having a build for every line is one of the reasons I love Docker. Merging the line as you mentioned above speeds up the installation but I would like to keep it one line for each command at the moment, because I still changing and playing around with the docker file. Having one line per command means I can leverage the cache much better. As soon as the Docker file is more stable, we should move to merging the lines as you mentioned above.
