PersistentVolume (PV) definition in Kubernetes - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define the API version for a PersistentVolume.

Kubernetes

apiVersion: [1]
kind: PersistentVolume
metadata:
  name: pv-example

Drag options to blanks, or click blank then click option'

Av1

Bv1beta1

Capps/v1

Dstorage.k8s.io/v1

Attempts:

💡 Hint

Common Mistakes

Using 'apps/v1' which is for deployments and other workload resources.

Using 'storage.k8s.io/v1' which is for StorageClass and CSI drivers.

The correct API version for PersistentVolume is v1.

medium

Complete the code to specify the PersistentVolume capacity.

Kubernetes

spec:
  capacity:
    storage: [1]

Drag options to blanks, or click blank then click option'

A10MB

B10GB

C10Gi

D10

Attempts:

💡 Hint

Common Mistakes

Using '10GB' which is not the correct unit in Kubernetes specs.

Omitting the unit, which causes errors.

The storage capacity must be specified with a unit like Gi for gibibytes.

hard

Fix the error in the PersistentVolume access mode specification.

Kubernetes

spec:
  accessModes:
    - [1]

Drag options to blanks, or click blank then click option'

AReadWriteOnce

BReadWriteMany

CReadOnlyOnce

DWriteOnlyOnce

Attempts:

3 left

💡 Hint

Common Mistakes

Using invalid access modes like 'WriteOnlyOnce'.

Confusing 'ReadOnlyOnce' with 'ReadOnlyMany'.

The valid access modes include ReadWriteOnce, ReadOnlyMany, and ReadWriteMany. ReadWriteOnce is commonly used.

4fill in blank

hard

Fill both blanks to define the PersistentVolume host path and reclaim policy.

Kubernetes

spec:
  hostPath:
    path: [1]
  persistentVolumeReclaimPolicy: [2]

Drag options to blanks, or click blank then click option'

A/mnt/data

BRetain

CDelete

D/var/lib/data

Attempts:

3 left

💡 Hint

Common Mistakes

Using relative paths for hostPath.

Using an invalid reclaim policy string.

The hostPath should point to a valid directory like /mnt/data. The reclaim policy Retain keeps the data after the volume is released.

5fill in blank

hard

Fill all three blanks to complete the PersistentVolume spec with storage class, volume mode, and capacity.

Kubernetes

spec:
  storageClassName: [1]
  volumeMode: [2]
  capacity:
    storage: [3]

Drag options to blanks, or click blank then click option'

BBlock

C20Gi

DFilesystem

💡 Hint

Common Mistakes

Using invalid volume modes.

Omitting units in capacity.

The storageClassName is a user-defined class like fast-storage. The volumeMode can be Filesystem or Block. The capacity must include a unit like 20Gi.
