Description Devan Goodwin 2021-09-22 17:14:14 UTC

Version:

failed 4.9 installs in CI, examples: 

OVN: https://prow.ci.openshift.org/view/gs/origin-ci-test/logs/periodic-ci-openshift-release-master-ci-4.10-upgrade-from-stable-4.9-e2e-aws-ovn-upgrade/1439917064897695744

SDN: https://prow.ci.openshift.org/view/gcs/origin-ci-test/logs/periodic-ci-openshift-release-master-ci-4.10-upgrade-from-stable-4.9-e2e-aws-upgrade/1440456016905900032

Platform: aws IPI

In the artifacts for these failed installs a log-bundle.tar is generated due to bootstrap failure.

In the bootkube.log you can see a large number of messages such as: 

bootstrap/journals/bootkube.log:Sep 21 23:44:37 ip-10-0-15-48 bootkube.sh[2293]: "0000_20_kube-apiserver-operator_00_cr-scc-hostaccess.yaml": unable to get REST mapping for "0000_20_kube-apiserver-operator_00_cr-scc-hostaccess.yaml": no matches for kind "ClusterRole" in version "rbac.authorization.k8s.io/v1"

Which is for a core type that should be present.

deads has prepared a:

proposed fix: https://github.com/openshift/library-go/pull/1219
proof pr: https://github.com/openshift/cluster-bootstrap/pull/64

Slack thread with deads and stts: https://coreos.slack.com/archives/C02FFM5PNSG/p1632319918039000

We are still trying to determine if these are why the installs are failing, but there's still a problem to be fixed here regardless.

$ w3m -dump -cols 200 'https://search.ci.openshift.org/?search=unable+to+get+REST+mapping&maxAge=336h&context=1&type=junit&name=&excludeName=&maxMatches=5&maxBytes=20971520&groupBy=job' | grep '4.10' | sort
No results found

And checked Jenkins Flexy install jobs with AWS + OVN profiles from 10/28/2021 until today,there are total 113 jobs including failed 25 jobs, made random selection of tests did not find the same problem.

Based on above, the PR fix works fine, move the bug VERIFIED.
