worker_processes <%= ENV['NGINX_WORKERS'] || 4 %>;

What kind of nginx tag is this? Is this valid on any config? Is this coming from a specific module, or is the config file processed externally before being pushed to nginx?

@Pierstoval The file is pre-processed by erb (Embedded RuBy), as far as I can tell it's expected to be installed by another buildpack.

A publicly accessible DNS (google) as your resolver is a security risk, no?
