Description Vadim Rutkovsky 2018-09-24 12:00:37 UTC
Documentation should to mention that only lowercase DNS names are supported, as kubelet now uses machine hostname as node name. Previously this could be overriden by openshift_hostname

Comment 2 Vadim Rutkovsky 2018-09-26 12:24:58 UTC
AFAIK upstream decision on this is done in https://github.com/kubernetes/kubernetes/issues/22063

Comment 3 Stephen Cuppett 2019-11-21 12:53:32 UTC
OCP 3.6-3.10 is no longer on full support [1]. Marking un-triaged bugs CLOSED DEFERRED. If you have a customer case with a support exception or have reproduced on 3.11+, please reopen and include those details. When reopening, please set the Version to the appropriate version where reproduced.

This change would still apply to 3.11.
