Access modes (ReadWriteOnce, ReadOnlyMany, ReadWriteMany) in Kubernetes - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the access mode to allow a volume to be mounted as read-write by a single node.

Kubernetes

accessModes:
  - [1]

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

💡 Hint

Common Mistakes

Choosing ReadOnlyMany which is read-only access by many nodes.

The ReadWriteOnce access mode allows the volume to be mounted as read-write by a single node.

2fill in blank

medium

Complete the code to set the access mode that allows multiple nodes to mount the volume as read-only.

Kubernetes

accessModes:
  - [1]

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

💡 Hint

Common Mistakes

Choosing ReadWriteMany which allows writing, not just reading.

ReadOnlyMany allows multiple nodes to mount the volume but only in read-only mode.

3fill in blank

hard

Fix the error in the access mode to allow multiple nodes to mount the volume with read-write access.

Kubernetes

accessModes:
  - [1]

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

💡 Hint

Common Mistakes

Using ReadWriteOnce which restricts write access to a single node.

ReadWriteMany allows multiple nodes to mount the volume with read-write access simultaneously.

4fill in blank

hard

Fill both blanks to complete the PersistentVolume spec with access modes for single-node read-write and multi-node read-only.

Kubernetes

spec:
  accessModes:
    - [1]
    - [2]

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

💡 Hint

Common Mistakes

Mixing up read-write and read-only modes.

The spec allows ReadWriteOnce for single-node read-write and ReadOnlyMany for multi-node read-only access.

5fill in blank

hard

Fill all three blanks to define a PersistentVolumeClaim that requests a volume with multi-node read-write access and a storage size of 10Gi.

Kubernetes

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: example-pvc
spec:
  accessModes:
    - [1]
  resources:
    requests:
      storage: [2]
  storageClassName: [3]

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

💡 Hint

Common Mistakes

Using ReadWriteOnce which restricts to one node.

Forgetting to specify storage size with units.

The claim requests ReadWriteMany access mode for multi-node read-write, storage size 10Gi, and uses the standard storage class.
