When a pod is created using kubectl run in Kubernetes, what type of label is automatically assigned to it?

• A. rollout:<name>
• B. run:<name>
• C. pod:<name>
• D. app:<name>

Answer: (B)

When you create a Pod with kubectl run, Kubernetes attaches a label that uses the key run and the value equal to the name you gave the Pod. This labeling makes it easy to identify and select those Pods later, for example with a command like kubectl get pods -l run=<name>. The other labels mentioned aren’t automatically added by this operation, so they aren’t the default label you’d see on the Pod.
