After OpenShift Container Platform upgrade to 3.7 getting multiple RBAC DENY errors.

Issue

• After upgrading from OCP 3.6 to 3.7 getting hundreds of messages within journald like the following (approximately one RBAC DENY error per image which physically resides within the internal Docker registry):
