| Use either `minAvailable` or `maxUnavailable` (not both, a number or a percentage). Make sure `minAvailable` is lower than `replicaCount`, otherwise node drains are blocked. Optionally set `unhealthyPodEvictionPolicy` to `IfHealthyBudget` or `AlwaysAllow`. The PodDisruptionBudget is only created when `manager.kind` is `Deployment`. |
