docker-compose nginx, container starts but nginx is not running on port 80, no errors

This was a tricky one.  I'm building a tool to spin up new Drupal instances, built on docker, using a distro.  I ran everything and the nginx container was running but using this command I could see nothing running on port 80, and nothing loaded in the browser.

netstat -tulpn

Solved this, there was no conf file in the /etc/nginx/conf.d, you need at least one or nginx will not run.  Added one, and it came back.
