Description Mat Kowalski 2021-08-03 20:53:52 UTC
When installing an OCP 4.8.3 with Baremetal IPI using dual-stack networking with IPv6 subnet listed as a primary one, the kube-apiserver-operator crashes when loading extension-apiserver-authentication.

Part of the error (with full in the attachment)

Provide kube-apiserver logs. From your operator logs I figure that you are able to talk to the API. Please run must-gather, upload and link here. Otherwise, we cannot triage this.

dual stack with IPv6 primary is not supported
