I am running minikube kubernetes cluster and used the script here: https://github.com/ContainerSolutions/registry-tooling
To secure a registry pod. The readme says "It will not currently configure a storage backend; please take a look at the config files to see how to do this." But I don't know what config files are referred to. In other words, how to configure a storage solution on a minikube VM (running on a MacOS host on a VirtualBox hypervisor) and configure it as the storage backend to the registry pod? (And make it accessible from the internet)
