This will only guarantee Pod termination previous to creation for upgrades. If you upgrade a Deployment, all Pods
of the old revision will be terminated immediately. Successful removal is awaited before any Pod of the new
revision is created. If you manually delete a Pod, the lifecycle is controlled by the ReplicaSet and the
replacement will be created immediately (even if the old Pod is still in a Terminating state). If you need an
"at most" guarantee for your Pods, you should consider using a
[StatefulSet](/docs/concepts/workloads/controllers/statefulset/).
