Kubernetes - Labels and Selectors

What will be the output of this command if the pod webapp already has a label env=staging and you run:
kubectl label pod webapp env=production --overwrite
Then check labels with:
kubectl get pod webapp --show-labels?

AThe pod will have label env=production

BThe pod will have both env=staging and env=production labels

CThe command will fail with an error

DThe pod will have no labels

Step-by-Step Solution

Solution:

Step 1: Understand the --overwrite flag effect
The --overwrite flag allows replacing an existing label value with a new one.
Step 2: Apply the command to the existing label
Since the pod has env=staging, running the command with --overwrite changes it to env=production.
Final Answer:
The pod will have label env=production -> Option A
Quick Check:

Quick Trick: Use --overwrite to change existing label values [OK]

Common Mistakes:

Expecting both old and new labels to exist
Thinking command fails without --overwrite
Assuming labels get deleted
