I’m running Nginx within a docker container and I was on a quest to make sure it wasn’t running as the root user. So the first thing I wanted to do was check the version of Nginx because I’ve read that it doesn’t run as root if the version is >1.12.1-r2. Source is just a github thread.

So I log into the nginx container via docker exec -it nginx bash and run nginx -v. This gives me the following output:

nginx version: nginx/1.17.8

That’s all I need to know. Of course after running this I ran ps aux | grep nginx to get this output:

bash-5.0# ps aux | grep nginx
    1 root      0:00 nginx: master process nginx -g daemon off;
    6 root      0:00 /bin/sh -c while :; do sleep 6h & wait ${!}; nginx -s reload; done & nginx -g "daemon off;"
   20 www-data  0:00 nginx: worker process
   21 www-data  0:00 nginx: worker process
   22 www-data  0:00 nginx: worker process
   23 www-data  0:00 nginx: worker process
   33 root      0:00 grep nginx

This showed me that the workers are running under www-data but not the main master process, so I’ll have to fix that (coming in another blog post shortly)
