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.

Now cluster-bot failed to install the cluster with "invalid configuration: you must define at least one test or image build in 'tests' or 'images'"

The bug still not verify it automatically, will do it manually.
The requests of the BZ https://bugzilla.redhat.com/show_bug.cgi?id=1947785#c0 are gone for the given component, you won't see the related alert in web-console. Verification steps, you can refer to https://bugzilla.redhat.com/show_bug.cgi?id=1947801#c4

I've opened Bug #1955100 to address the samples operator config CRD. For this scope of this bug, please re-verify that the alert is not present for the builds.config.openshift.io custom resource.
Verified in version: 4.8.0-0.nightly-2021-04-29-151418 From console and executed commands according Comment 6, no alert from build.config.openshift.io custom resoure.
Created attachment 1777542 [details] alert page
Actually, there is one bug 1949593 - rename DeprecatedAPIInUse alert to APIRemovedInNextReleaseInUse, so you cannot see the name DeprecatedAPIInUse alert from UI, caused this alert firing, because there are some requests from /apis/apiextensions.k8s.io/v1beta1/customresourcedefinitions/configs.samples.operator.openshift.io of this BZ component.
Oh, yes i can see APIRemovedInNextReleaseInUse in alert ui, about alert for builds.config.openshift.io custom resource, I execute commands according comments 6, no result now, do you think if it can be verified the bug? @kewang, thanks
@wewang, yes, no longer see the requests of this BZ component, it is fixed.
