Question
Which Kubernetes resource uses immutable: true boolean field?
Options
- ADeployment
- BPod
- CConfigMap
- DReplicaSet
Explanation
The ConfigMap resource supports an immutable: true boolean field to prevent accidental updates or deletions of its data.
Common mistakes.
- A. Deployments are designed to be updated via strategies like rolling updates, so they do not have an
immutablefield for their entire configuration. - B. Pods can be replaced or recreated, but the Pod resource itself does not have an
immutablefield to lock its definition after creation; changes typically lead to recreation. - D. ReplicaSets ensure a stable set of running Pods, and while their template can be updated, the ReplicaSet resource itself does not have an
immutablefield to prevent modifications.
