Description Devan Goodwin 2019-04-02 18:36:29 UTC

Description of problem:

https://openshift-gce-devel.appspot.com/build/origin-ci-test/pr-logs/pull/openshift_installer/1519/pull-ci-openshift-installer-master-e2e-aws/4868#openshift-tests-k8sio-kubelet-when-scheduling-a-busybox-pod-with-hostaliases-should-write-entries-to-etchosts-nodeconformance-conformance-suiteopenshiftconformanceparallelminimal-suitek8s


Looks to be appearing as a failure in every test run right now.

Clayton suggests disabling the test for now.

Comment 1 Dan Mace 2019-04-02 19:10:27 UTC

Ravi, PTAL since this intersects with the /etc/hosts support in dns-operator.

Comment 2 Dan Mace 2019-04-09 15:20:47 UTC

Here's an example /etc/hosts from a node:


127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.30.23.104 image-registry.openshift-image-registry.svc image-registry.openshift-image-registry.svc.cluster.local # openshift-generated-node-resolver

The entry on line 3 is maintained by the `dns-node-resolver` container in `openshift-dns/dns-default` pods on nodes.

Comment 3 Dan Mace 2019-04-26 15:47:16 UTC

This test has been re-enabled for 22 days:

https://github.com/openshift/origin/commit/fb601b2c65e5a32b5144186392bf31472ca14efd

And the only 2 occurrences of the test failing over the last couple of days over 548 failures are due to test panics which appear to be collateral from a wider problem:

https://openshift-gce-devel.appspot.com/build/origin-ci-test/pr-logs/pull/22442/pull-ci-openshift-origin-master-e2e-aws/7860
https://openshift-gce-devel.appspot.com/build/origin-ci-test/pr-logs/pull/22661/pull-ci-openshift-origin-master-e2e-aws/7903

I'm going to call this flake solved for now. If new evidence appears, we can open a new bug.

Comment 4 Hongan Li 2019-04-29 06:05:32 UTC

I'm going to move this to verified, please reopen if it still exists in latest CI test.
