Missing chefadmin.pem


I am trying to follow this guide for learning chef and am having issues with getting the chefadmin.pem file to show up after running the script it said to. I ran it with correct permissions and with root too. I can’t seem to figure it out. The script failed the first time and hung for an hour. I reran it and it seemed to have worked until I tried to find the file to continue the learning guide.

I have used the ‘find’ command on ubuntu 14.04. I am running this in a docker container on Mac OS 10.13 I am not too sure how to get the file out of the container either
