So, let's see if #hachyderm or the further #Federation can give me a hand with some #kubernetes (#k8s).
I've got 2 containers running on the same pod. One of them (nginx) run as root and the other (app) doesn't. I'm trying to have a shared volume between the 2 using an emptyDir, but when I try to copy files on initContainer using the non-root img, I get an error telling me "Operation not permitted" when trying to chgrp the volume. Can I change the ownership of the volume? securityContext? #help
