nginx - Set directive into 'main' context; i.e.: "worker_processes"

[vlauciani]

Hi

Reading the guide here:

• https://dockerfile.readthedocs.io/en/latest/content/DockerImages/dockerfiles/php-nginx.html

or the issue:

• [Question] How to change nginx worker_connections / log format of webdevops/php-nginx image #399

I understand that to update the nginx conf I need to add my file into /opt/docker/etc/nginx/conf.d directory; this adds the configuration into http {} context. For example I can add multiple server {} context:

http {
  server {
  }
  server {
  }
}

But how I can add directive like worker_processes that is in main context? Should I override the file /etc/nginx/nginx.conf?

Thank you
