Customized Nginx image

This Dockerfile relies on official library Dockerfile with a customized entrypoint allowing to perform custom configuration with shell scripts found in /docker-entrypoint.d/ during container startup.

Currently registered script(s) :

1. optionally interpolate the environment variable present in any file under /cm_configs with a filename suffix .sample and move all files to their respective directory (see below).

Nginx-specific configuration:

The file /cm_configs_default/etc/nginx/nginx.conf.sample will be provided by default. The docker-entrypoint scripts will interpolate env vars into it and produce the final /etc/nginx/nginx.conf.
