docker-gen

nginx-proxy/docker-gen with:

• embedded nginx.tmpl file
• support for NGINX_* environment variables
• docker socket by default located in /var/run/docker.sock, same as in letsencrypt companion

Environment variables starting with NGINX_* are added as nginx config entries, for example: NGINX_CLIENT_MAX_BODY_SIZE=30M. Variables of docker-gen container are added to global config, and variables on others containers are added to the respective vhosts.

This fork automatically pulls and rebuilds Docker Hub image on any changes in the upstream repo
