Description Dan Winship 2020-03-02 23:36:12 UTC

+++ This bug was initially created as a clone of Bug #1809368 +++

There are bugs with the IPv6DualStack feature flag in 1.17/4.4 even in single-stack clusters. Bug 1794376 removed it from openshift/api and updated cluster-kube-apiserver-operator but didn't update cluster-kube-controller-manager-operator so we were still setting that flag for kcm.

Comment 1 Dan Winship 2020-03-02 23:37:16 UTC

This already happened. I just need there to be a bug to appease the bot.

oh, but apparently I don't have to cheat; we can merge the 4.4 fix with this still at MODIFIED

so, for QE: the thing to verify is that kube-controller-manager's command-line arguments don't include IPv6DualStack in the --feature-gates
