How to trigger reconcile on updates to container status

[cclarkedt]

My controller owns and is responsible for making a deployment. The one container in this deployment has a liveness and startup probe. When the probes reach their failure threshold kubelet restarts the container. On this event when kubelet restarts the container I'd like to receive a reconcile to retrieve the latest container status (which I am currently not).

My understanding was that because my controller Owns(&corev1.Pod{}) (and the pod has the correct owner refs), that the update event on the pod triggered by kubelet of Warning Unhealthy 4m17s (x45 over 39m) kubelet Liveness probe failed: HTTP probe failed with statuscode: 503 would cause a reconcile. Is there something I am missing?

Manager setup:

func ignoreStatusUpdates() predicate.Predicate {
	return predicate.Funcs{
		UpdateFunc: func(e event.UpdateEvent) bool {
			// Ignore updates to CR status in which case metadata.Generation does not change
			return e.ObjectOld.GetGeneration() != e.ObjectNew.GetGeneration()
		},
	}
}

func (r *MyController) SetupWithManager(mgr ctrl.Manager) error {
	return ctrl.NewControllerManagedBy(mgr).
		For(&appv1alpha1.MyCR{}, builder.WithPredicates(ignoreStatusUpdates())).
		Owns(&appsv1.Deployment{}).
		Owns(&corev1.Pod{}).
		Owns(&corev1.Secret{}).
		Owns(&corev1.ConfigMap{}).
		Owns(&corev1.Service{}).
		Complete(r)
}

Seeing strange behaviour where it will trigger the reconcile and work as I would have expected but not immediately
