Doc Type: Bug Fix
Doc Text:
Cause: In unidling proxy mode of openshift-sdn, it was expected for the endpoint to get deleted always after the service gets deleted. However this might not be the case always and if the endpoint got deleted before the service, it would induce this bug. Consequence: Though the service and endpoint would get deleted, the nodeport wasn't getting deleted and would remain stuck open in the unidling proxy mode. Fix: Removed dependency on the order in which service and endpoint need to be deleted and ensure all the necessary resources get deleted completely irrespective of which one (service or endpoint) gets deleted first in the unidling proxy mode. This was fixed in openshift-sdn 4.6 and backported to 3.11. Result: nodeport gets deleted correctly.
