If a StatefulSet named 'web' has a pod with index 2, what is its pod name?

If a StatefulSet named 'web' has a pod with index 2, what is its pod name?

• A. web-2
• B. web-2nd
• C. web-02
• D. web-pod-2

Answer: (A)

StatefulSet pods get stable, unique names formed from the StatefulSet name and the pod’s ordinal index, in the format <statefulset-name>-<ordinal>. The ordinal is a zero-based decimal number, so index 0, then 1, then 2, and so on. Therefore, for a StatefulSet named web with a pod at index 2, the pod name is web-2. Other options don’t match this standard naming (they add a suffix like “2nd,” include a leading zero, or add extra words).
