The feature allows cluster administrators to explicitly define the ordering of pods during graceful node shutdown based on priority classes.\n\nThe Graceful Node Shutdown feature, as described above, shuts down pods in two phases, non-critical pods, followed by critical pods. If additional flexibility is needed to explicitly define the ordering of pods during shutdown in a more granular way, pod priority based graceful shutdown can be used.\n\nWhen graceful node shutdown honors pod priorities, this makes it possible to do graceful node shutdown in multiple phases, each phase shutting down a particular priority class of pods. The kubelet can be configured with the exact phases and shutdown time per phase.\n\nAssuming the following custom pod priority classes in a cluster,\n\nWithin the kubelet configuration the settings for shutdownGracePeriodByPodPriority could look like\n\nThe corresponding kubelet config YAML configuration would be\n\nBounded code example (external data; do not execute automatically):\n```yaml\nshutdownGracePeriodByPodPriority:\n  - priority: 100000\n    shutdownGracePeriodSeconds: 10\n  - priority: 10000\n    shutdownGracePeriodSeconds: 180\n  - priority: 1000\n    shutdownGracePeriodSeconds: 120\n  - priority: 0\n    shutdownGracePeriodSeconds: 60\n```\n\nThe above table implies that any pod with priority value >= 100000 will get just 10 seconds to shut down, any pod with value >= 10000 and = 1000 and < 10000 will get 120 seconds to shut down. Finally, all other pods will get 60 seconds to shut down.\n\nOne doesn't have to specify values corresponding to all of the classes. For example, you could instead use these settings\n\nIn the above case, the pods with custom-class-b will go into the same bucket as custom-class-c for shutdown.\n\nIf there are no pods in a particular range, then the kubelet does not wait for pods in that priority range. Instead, the kubelet immediately skips to the next priority class value range.\n\nIf this feature is enabled and no configuration is provided, then no ordering action will be taken. …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
