Use it:
$ generate_nginx_config nginx_config.yml /etc/nginx.conf

See an example config file:
$ generate_nginx_config —example

You can set two environment variables:
– NGINX_CONFIG_YAML to specify the YAML config file
– NGINX_CONFIG_FILE to specify the nginx config file

By default, generate_nginx_config won’t overwrite your OUT file. To rock this behavior,
pass in —overwrite or -o or -y or —force or -f. Whichever.

Vhosts:
If you have installed nginx on ubuntu via apt-get / aptitude or wish to only generate virtual hosts
instead of a whole config pass in —vhosts, —vhost or —ubuntu. This spits out a vhosts file
which you can pop in your sites-available directory.
