    Description

      In the node healthz server, leveraged by cloud load balancers to check the node health for services with ExternalTrafficPolicy=Cluster, we should respond negatively to health checks as soon as the ovnk node pod is to be deleted, by inspecting the pod DeletionTimestamp.

      This allows cloud load balancers to have a little more time to update their list of healthy nodes before the node actually stops altogether forwarding traffic.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
