5.3.3. Mounting the hostPath share in a privileged pod

Prerequisites

• A persistent volume claim exists that is mapped to the underlying hostPath share.

Procedure

• Create a privileged pod that mounts the existing persistent volume claim:

  apiVersion: v1
  kind: Pod
  metadata:
    name: pod-name 

  1

  
  spec:
    containers:
      ...
      securityContext:
        privileged: true 

  2

  
      volumeMounts:
      - mountPath: /data 

  3

  
        name: hostpath-privileged
    ...
    securityContext: {}
    volumes:
      - name: hostpath-privileged
        persistentVolumeClaim:
          claimName: task-pvc-volume 

  4

  1

  The name of the pod.

  2

  The pod must run as privileged to access the node’s storage.

  3

  The path to mount the host path share inside the privileged pod. Do not mount to the container root, /, or any path that is the same in the host and the container. This can corrupt your host system if the container is sufficiently privileged, such as the host /dev/pts files. It is safe to mount the host by using /host.

  4

  The name of the PersistentVolumeClaim object that has been previously created.
