Description Dan Winship 2020-03-02 23:47:11 UTC

+++ This bug was initially created as a clone of Bug #1809372 +++

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 machine-config-operator so we were still setting that flag for kubelet

Comment 2 Ryan Phillips 2020-03-03 22:04:33 UTC


*** This bug has been marked as a duplicate of bug 1809372 ***

Comment 3 Dan Winship 2020-03-05 19:40:47 UTC

not a dup, this was the 4.4 clone
