Description Luis Tomas Bolivar 2019-09-30 16:31:17 UTC

When there is a pod (and a svc) with a NP allowing access from a namespace with a give label, and another namespace label is updated to have the allowed label, the NP SG rules that are applied to the initial pod are updated to allow the updated namespace but not the rules on the loadbalancers, so the traffic does not go through.

Comment 2 Jon Uriarte 2019-10-03 16:17:55 UTC

Verified on an OCP 4.2 cluster (4.2.0-0.nightly-2019-10-02-001405) with Kuryr-controller image from OCP 4.3 (4.3.0-0.ci-2019-10-02-101344),
which includes the fix.
Verified that the fix does not add new regressions as well.

$ oc get pods -n openshift-kuryr kuryr-controller-5744b8d79d-wpdjl -o yaml | grep image
   image: registry.svc.ci.openshift.org/ocp/4.3-2019-10-02-101344@sha256:313a91b60fb5f49ece7e351ffee86e6f799b4399025d07cff9df8fec5adb5d06

It was not possible to verify on OCP 4.3 cluster as there are no nightly builds available at the moment.

Comment 5 Jon Uriarte 2019-10-18 08:08:58 UTC

Verified on OCP 4.3.0-0.nightly-2019-10-17-061631 build on top of OSP 13 2019-10-01.1 puddle.

release image: registry.svc.ci.openshift.org/ocp/release@sha256:2cafe25ec1ed2dfdec361cde13b4461d2a30194d0b41fbd1c6d3fad5ab34ca05

Related K8s NP upstream test -should allow ingress access from updated namespace- test passed.
