Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a StorageClass with dynamic provisioning.

Kubernetes

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: fast
provisioner: [1]

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

Akubernetes.io/host-path

Bkubernetes.io/no-provisioner

Ckubernetes.io/aws-ebs

Dkubernetes.io/static-provisioner

💡 Hint

Common Mistakes

Using a provisioner that does not support dynamic provisioning.

Confusing static provisioner names with dynamic ones.

The provisioner field specifies the volume plugin that provisions volumes dynamically. For AWS EBS, it is kubernetes.io/aws-ebs.

Complete the code to set the reclaim policy to delete volumes after release.

Kubernetes

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: fast
reclaimPolicy: [1]

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

💡 Hint

Common Mistakes

Using Retain which keeps the volume after release.

Using invalid reclaim policy values.

The reclaimPolicy set to Delete means the volume will be deleted when released.

Fix the error in the StorageClass definition by completing the missing field.

Kubernetes

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: slow
provisioner: [1]

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

Akubernetes.io/host-path

Bkubernetes.io/gce-pd

Ckubernetes.io/aws-ebs

Dkubernetes.io/no-provisioner

Attempts:

💡 Hint

Common Mistakes

Using a provisioner not supported by the cloud environment.

Using no-provisioner which disables dynamic provisioning.

The kubernetes.io/gce-pd provisioner is used for Google Compute Engine Persistent Disks.

Fill both blanks to create a StorageClass with volume binding mode set to WaitForFirstConsumer.

Kubernetes

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: delayed
provisioner: [1]
volumeBindingMode: [2]

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

Akubernetes.io/aws-ebs

BImmediate

CWaitForFirstConsumer

Dkubernetes.io/gce-pd

Attempts:

3 left

💡 Hint

Common Mistakes

Using Immediate which binds volume immediately.

Mixing provisioners and volume binding modes incorrectly.

The volumeBindingMode set to WaitForFirstConsumer delays volume binding until a pod uses the PVC. The provisioner kubernetes.io/aws-ebs is for AWS EBS volumes.

5fill in blank

hard

Fill all three blanks to create a StorageClass with parameters for type gp2 and allowVolumeExpansion enabled.

Kubernetes

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: expandable
provisioner: [1]
parameters:
  type: [2]
allowVolumeExpansion: [3]

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

Akubernetes.io/aws-ebs

Bgp2

Ctrue

Dfalse

Attempts:

💡 Hint

Common Mistakes

Using false for allowVolumeExpansion when expansion is needed.

Incorrect provisioner or parameter values.

This StorageClass uses AWS EBS with type gp2 and allows volume expansion by setting allowVolumeExpansion to true.
