PodSpec.evictionResponders
evictionResponders reference responders that react to Evictions based on EvictionRequests. Responders should observe and communicate through the Eviction Resource API to help with the graceful termination of a pod. The responders are selected sequentially, according to their specified priority. Responders should periodically report on an eviction progress by updating the .status.responders[].heartbeatTime field of the Eviction object. If this field is not updated within the heartbeat deadline defined by the Eviction API (currently 20 minutes), the eviction is passed over to the next responder with a lower priority. If there is no other responder, the last default imperative-eviction.k8s.io/evictor responder with a priority of 100 will evict the pod using the imperative Eviction API (pods/<name>/eviction subresource). The maximum length of the responders list is 10. Responders are not supported when the pod is part of a PodGroup (.spec.schedulingGroup is set). This field can only be set on creation and is immutable afterwards.
| Field / Type | Description |
|---|---|
name | name allows you to identify the responder responding to the Eviction. It must be a valid domain-prefixed key (such as "acme.io/foo"). Domain names *.k8s.io and *.kubernetes.io are reserved. This field must be unique for each responder. This field is required. |
priority | priority for this responder. Higher priorities are selected first by the evictionrequest-controller. If there are responders with the same priority, the responder whose domain name comes first in the alphabetical higher domain order, will be picked. This means that the top domain labels are compared alphabetically first, followed by the lower domain labels. The key is compared last. The responder that is the managing controller of the pod should set the value of this field to 10000 to allow both for preemption or fallback registration by other responders. The minimum value is 0 and the maximum value is 100000. The interval 0-999 is reserved for responders with *.k8s.io suffix. This field is required.
