RxNorm with Google Cloud launchpad OpenEMR

Situation
The installation instructions for the RxNorm external data source gives instructions for the windows version of OpenEMR, but we are currently in the stage of migrating to the google cloud launchpad version of OpenEMR, where it is not instantly obvious where to put the RxNorm zip file. Where do I find the installation directory when I SSH into the server?

OpenEMR Version
I’m using OpenEMR version 5.0.1 using the Google Cloud Launchpad

contrib/rxnorm

Can you give a directory for that in the style of a Google Cloud Launchpad instance? I can’t find a folder called contrib. I know that that is the directory for a windows install.

pretty sure it’s in the apache docker but haven’t visited the google cloud, maybe openemr-devops/packages/launchpad at master · openemr/openemr-devops · GitHub will help
