Como montar todo o diretório “/” de um contêiner do linux em um persistentVolume no AWS k8s

Question

É possível usar o PersistentVolume para montar todo o diretório "/" de um contêiner do Linux.

Estou tentando montá-lo, mas ele falha. Eu basicamente quero um contêiner, onde eu estaria fazendo, várias alterações througtout e quero que essas alterações persistam em travamentos do pod / restart

   ubuntu@kops:/tmp$ cat pod.yaml
    kind: Deployment
    apiVersion: apps/v1beta2
    metadata:
      name: task-pod
    spec:
      replicas: 1
      selector:
        matchLabels:
          app: testing
      template:
        metadata:
         labels:
          app: testing
        spec:
           containers:
           - name: nginx
             image: nginx:1.7.9
             ports:
             - containerPort: 80
             volumeMounts:
             - mountPath: "/"
               name: task-pv
           volumes:
           - name: task-pv
             persistentVolumeClaim:
                claimName: task-pvc
