You want to deploy a StatefulSet with 3 replicas but require pods to start in parallel instead of sequentially. Which field should you modify to achieve this?

hard📝 Best Practice Q15 of 15

Kubernetes - Persistent Storage

ASet <code>serviceName</code> to empty string.

BSet <code>replicaCount: 3</code> in the pod template.

CSet <code>podManagementPolicy: Parallel</code> in the StatefulSet spec.

DSet <code>updateStrategy: RollingUpdate</code> in the StatefulSet spec.

Step-by-Step Solution

Solution:

Step 1: Understand podManagementPolicy in StatefulSets
By default, StatefulSets create pods sequentially. Setting podManagementPolicy to Parallel allows parallel pod creation.
Step 2: Identify correct field to change
Changing podManagementPolicy to Parallel in the spec enables parallel pod startup.
Final Answer:
Set podManagementPolicy: Parallel in the StatefulSet spec. -> Option C
Quick Check:
podManagementPolicy controls pod start order [OK]

Quick Trick: Use podManagementPolicy: Parallel to start pods together [OK]

Common Mistakes:

Changing replicaCount instead of podManagementPolicy
Confusing updateStrategy with pod start order
Removing serviceName breaks network identity
