I’m adding UpcomingSprint, because I was occupied by fixing bugs with higher priority/severity, developing new features with higher priority, or developing new features to improve stability at a macro level. I will revisit this bug next sprint.

I will revisit this bug next sprint. The linked customer issue is closed and given this was most likely caused by a 3rd party mutating admission webhook I'm going to close this issue.

Description of problem: The addition of a MutatingAdmissionWebhook is causing pod deployment failures and other errors when running commands such as the following: ~~~~~~~~~~ $ oc debug node/...com Error from server (InternalError): Internal error occurred: admission plugin "MutatingAdmissionWebhook" failed to complete mutation in 13s ~~~~~~~~~~ ~~~~~~~~~~ 2020-10-16T16:21:17.357064063Z I1016 16:21:17.357024 1 event.go:255] Event(v1.ObjectReference{Kind:"ReplicaSet", Namespace:"openshift-operator-lifecycle-manager", Name:"olm-operator-9d666b5b9", UID:"69c72a6d-f1b7-49b6-bc45-9e611c6bffda", APIVersion:"apps/v1", ResourceVersion:"142186292", FieldPath:""}): type: 'Warning' reason: 'FailedCreate' Error creating: Internal error occurred: admission plugin "MutatingAdmissionWebhook" failed to complete mutation in 13s 2020-10-16T16:21:17.357112317Z E1016 16:21:17.357103 1 replica_set.go:534] sync "openshift-operator-lifecycle-manager/olm-operator-9d666b5b9" failed with Internal error occurred: admission plugin "MutatingAdmissionWebhook" failed to complete mutation in 13s ~~~~~~~~~~ How reproducible: Consistently Actual results: Adding MutatingAdmissionWebhook is causing problems for cluster components. Expected results: MutatingAdmissionWebhook would work as expected without adverse affects on the cluster.
