A library catalog Deployment must stay available to citizens during an update. Which rollingUpdate setting directly limits how many Pods may be down at once?
Select an answer to reveal the explanation.
Short Explanation
Availability during a paint job means you only take so many shelves offline at once. maxUnavailable is that shelf limit for Pods—it caps how many can be missing while RollingUpdate runs.
Full Explanation
In a Deployment's rollingUpdate parameters, maxUnavailable limits how many Pods may be unavailable relative to the desired count during a rollout, protecting service capacity. revisionHistoryLimit and progressDeadlineSeconds govern history retention and failure detection, not concurrent unavailability. terminationGracePeriodSeconds affects Pod shutdown timing, not rollout concurrency.
