I have two containers, one running phpfpm and the other running nginx. I'd like the container running nginx to access the webroot files which has css and javascript files. Right now, nginx successfully passes off php requests to phpfpm, but no styles are showing up for instance when the webpage is rendered.

This is running off of minikube on a linux system.
