SharedIndexInformer events not detecting Terminating state of a pod

Is your enhancement related to a problem? Please describe

I need to detect when pod is entering “Terminating” state.

SharedInformerFactory factory = kubernetesClient.informers();
informer=factory.sharedIndexInformerFor(Pod.class, new OperationContext().withNamespace("ns"),10 * 1000L);
informer.addEventHandler(new ResourceEventHandler<Pod>() {...}

Delete event is triggered when pod is completely terminated, but I need when it begins the termination.

See https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/#pod-phase - Terminating is not actually a phase:

Note: When a Pod is being deleted, it is shown as Terminating by some kubectl commands. This Terminating status is not one of the Pod phases. A Pod is granted a term to terminate gracefully, which defaults to 30 seconds. You can use the flag --force to terminate a Pod by force.

So you’ll need to instead check for the metadata.deletionTimestamp as an indication that the pod is terminating.

You should check the pod status in onUpdate.
