+++ This bug was initially created as a clone of Bug #1812877 +++ we need to move https://github.com/kubernetes/kubernetes/pull/88763 so that errors like configmap_cafile_content.go:102] unable to load initial CA bundle for: "client-ca::kube-system::extension-apiserver-authentication::client-ca-file" due to: configmap "extension-apiserver-authentication" not found will not be printed at the server startup.
The pull I referenced in my previous comment will be part of the upcoming Kubernetes release (1.18). The new release will be incorporated into Origin in this sprint. Given that and the fact that the fix only removes a line from the log file, I'm moving this issue to VERIFIED state.
