 ## Overview
 This is a Dockerfile/image to build a container for nginx and php-fpm, with the ability to pull website code from git when the container is created, as well as allowing the container to push and pull changes to the code to and from git. The container also has the ability to update templated files with variables passed to docker in order to update your code and settings. There is support for lets encrypt SSL configurations, custom nginx configs, core nginx/PHP variable overrides for running preferences, X-Forwarded-For headers and UID mapping for local volume support.
