Where is nginx executable inside box?

I need to see if it was compiled with the debug option (so I can use error_log ‘debug’ level).

When I search the box, no luck:

I don’t see any nginx executable, I looked at all the usual places without luck, etc etc… I just want to get the version number and all the options with nginx -V

Bonus points: where is the final (compiled by vhost_gen.py) nginx.conf stored?!

connect to the httpd container.
