Description Stefan Schimanski 2021-04-09 09:34:45 UTC
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.

Here are the observed requests for this component:

system:serviceaccount:openshift-cluster-version:default: /apis/apiextensions.k8s.io/v1beta1/customresourcedefinitions/networks.config.openshift.io

system:serviceaccount:openshift-cluster-version:default: /apis/rbac.authorization.k8s.io/v1beta1/clusterrolebindings/default-account-cluster-network-operator

but the api versions are all actually v1, which means apiserver_requested_deprecated_apis may post the wrong result

Comment 4 Ke Wang 2021-04-23 10:37:43 UTC
I did a quick check, seems there were still requests for network component,
$ oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS

$ 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 networks

Comment 5 Ke Wang 2021-04-27 11:07:49 UTC
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

Comment 6 Ke Wang 2021-04-28 12:53:27 UTC
$ oc get clusterversion

system:serviceaccount:openshift-cluster-version:default: /apis/rbac.authorization.k8s.io/v1beta1/clusterrolebindings/default-account-cluster-network-operator

There are still requests of default-account-cluster-network-operator v1beta1 in audit.log, so I think the bug was not fixed completely, so assign back.
