Nginx running extra process in container

I am wondering why the web container (docker version stable-6173) has a Ningx process running as root when the only Nginx that should be running(based on what I can find in the code) is the process triggered by the Nginx run file(“exec nginx -c /config/nginx/nginx.conf”) which sets config file to “/etc/nginx/nginx.conf” where user is “www-data”.

Perhaps a process that should not be running?

The first one is the master process, the others are the workers. That’s normal

Thank you for explaining the reason.

Nginx seems to have a misconfigured conf file on the Web container if we switch from static values in this file back to env variables. Will post a fix here.
