Dockerfile: Apache / PHP 7.2 Development Environment

Dockerfile

FROM php:7.2-apache

# This Gist file accompanies my article on Medium for creating a PHP, MySQL and Redis development environment 
#   on macOS. This Dockerfile will create an APACHE, PHP 7.2 server that includes the Xdebug, Igbinary and 
#   Redis PHP extensions from PECL. It will also create PHP.ini overrides that will point session management 
#   to the Redis server created in this same article.
#
#   The article can be found here:
