      This is a clone of issue OCPBUGS-7431. The following is the description of the original issue:
      —

      Description of problem:

      Porting rhbz#2057740 to Jira. Pods without a controller: true entry in ownerReferences are not gracefully drained by the autoscaler (and potentially other drain-library drainers). Checking a recent 4.13 CI run:

      $ curl -s https://gcsweb-ci.apps.ci.l2s4.p1.openshiftapps.com/gcs/origin-ci-test/logs/periodic-ci-openshift-release-master-ci-4.13-e2e-aws-ovn/1625150492994703360/artifacts/e2e-aws-ovn/gather-extra/artifacts/pods.json | jq -r '.items[].metadata | select([(.ownerReferences // [])[] | select(.controller)] | length == 0) | .namespace + " " + .name + " " + (.ownerReferences | tostring)' | grep -v '^\(openshift-etcd\|openshift-kube-apiserver\|openshift-kube-controller-manager\|openshift-kube-scheduler\) '

      Version-Release number of selected component (if applicable):

      At least 4.11 and 4.13 (above). Likely all OpenShift 4.y which have had these openshift-marketplace pods.

      How reproducible:

      100%

      Steps to Reproduce:

      1. Launch a cluster.
      2. Inspect the openshift-marketplace pods with: oc -n openshift-marketplace get -o json pods | jq -r '.items[].metadata | select(.namespace == "openshift-marketplace" and (([.ownerReferences[] | select(.controller == true)]) | length) == 0) | .name + " " + (.ownerReferences | tostring)'

      Actual results:

      certified-operators-fnm5z [{"apiVersion":"operators.coreos.com/v1alpha1","blockOwnerDeletion":false,"controller":false,"kind":"CatalogSource","name":"certified-operators","uid":"4eb36072-7c56-4663-9b5a-fd23cee85432"}]

      Expected results:

      No output.

      Additional info:

      Figuring out which resource to list as the controller is tricky, but there are workarounds, including pointing at the triggering resource or a ClusterOperator as the controller.
