This component accesses APIs that will be removed in 4.9 (Kubernetes 1.22). It is causing the DeprecatedAPIInUse alert to fire in every 4.8 clusters permanently and hence must be fixed in 4.8 (blocker+). The raw audit data can be found at https://gist.github.com/sttts/50a1429837f2448ce07f30174fa73cdb.

This bug's PR is dev-approved and not yet merged, so I'm following issue DPTP-660 to do the pre-merge verifying for QE pre-merge verification goal of issue OCPQE-815 by using the bot to launch a cluster with the open PR. Here is the verification steps: $ masters=$(oc get no -l node-role.kubernetes.io/master | sed '1d' | awk '{print $1}') $ oc adm node-logs $masters --path=kube-apiserver/audit.log --raw | grep -e '"k8s.io/removed-release":"1.22"' | tee dep.json $ cat dep.json | jq -r '.user.username+": "+.requestURI' | sort | uniq | grep storages Nothing can be found. $ oc get clusterversion NAME VERSION AVAILABLE PROGRESSING SINCE STATUS version 4.8.0-0.ci.test-2021-04-30-025007-ci-ln-8rxw1fk True False 58m Cluster version is 4.8.0-0.ci.test-2021-04-30-025007-ci-ln-8rxw1fk So the bug is pre-merge verified. After the PR gets merged, the bug will be moved to VERIFIED by the bot automatically or, if not working, by me manually.
