What does maxSurge: 25% signify?

• A. It restricts to 25% of desired during updates
• B. It allows increasing by 25% above the desired amount during an update
• C. It ensures 25% of pods are updated at a time
• D. It sets maximum restarts to 25% during update

Answer: (B)

maxSurge controls how many extra pods can be created above the desired count during a rolling update. With a value of 25%, Kubernetes may bring up up to 25% more pods than you want running at once while the update proceeds. For example, if the deployment aims for 8 pods, maxSurge 25% allows up to 2 additional pods temporarily, for a total of 10 during the update. Once old pods are terminated, the total returns to the desired 8. This setting isn’t about how many pods you update at once or about restarts; it’s about providing temporary capacity above the desired number to keep traffic served during the rollout.
