I'm using the PersistentVolume functionality for sharing VM directories with Pods. For example:
apiVersion: v1
kind: PersistentVolume
metadata:
  name: psql-data-disk
spec:
  accessModes:
    - ReadWriteOnce
  capacity:
    storage: 1Gi
  hostPath:
    path: /data/psqldata
But I can't figure out how to delete the directory from the host VM so that I can reset the data. Minikube persists the /data/ directory across VM reboots, but doesn't document where it's storing it.
If you kubectl delete PersistentVolume psql-data-disk it doesn't delete any of the contents in the directory itself, it just deletes the K8s resource.
I'm using the docker-machine-driver-xhyve driver installed via brew on OSX Sierra.
 
                        
Ugh, I hadn't known about the
minikube sshcommand to get into the VM. So I just went in there and deleted the directory.
