Answer
It creates new Pods before terminating old ones, controlled by maxSurge and maxUnavailable.
Quick Answer
Rolling updates gradually replace old Pods with new ones. Kubernetes creates new Pods with the new image, waits for them to pass readiness probes, then terminates old ones — maxSurge controls how many extra Pods are created, maxUnavailable controls how many old Pods can be down at once. Traffic only routes to ready Pods throughout.
