Description Luis Tomas Bolivar 2019-10-09 14:39:55 UTC

There are different races between retry actions (activation vif, getting vif for a pod, ...) and deletion actions. It may happen that some retry action gets postponed until the resource has already been deleted, leaving to kuryr-controller errors

Comment 2 Jon Uriarte 2019-10-18 16:08:22 UTC

Verified on OCP 4.3.0-0.nightly-2019-10-18-051534 build on top of OSP 13 2019-10-01.1 puddle.

release image: registry.svc.ci.openshift.org/ocp/release@sha256:2a8f99a817784b303bd76706e14b23cffd98fca1e96b672dfb0b534a79ec5a86

Before this BZ was fixed these errors were shown in kuryr-controller logs when running openshift-tests:

· ERROR kuryr_kubernetes.handlers.retry [-] Report handler unhealthy VIFHandler: PortNotFoundClient: Port d3b2d608-19cd-4ef4-b726-b98119ef0cae could not be found.
· ERROR kuryr_kubernetes.handlers.logging NotFound: Subnet 039d7edf-3942-40cc-af46-0ed867e2a18c could not be found.
· ERROR kuryr_kubernetes.handlers.logging self._drv_vif_pool.delete_network_pools(net_crd['spec']['netId'])
  ERROR kuryr_kubernetes.handlers.logging TypeError: 'NoneType' object has no attribute '__getitem__'

After executing openshift/origin e2e kubernetes/conformance tests none of those messages were found, and kuryr-controller pod was not restarted due to them.
