IPv6DualStack flag deprecated in 1.25

[Jeremy Brisko]

In the kubernetes_control_plane.py there are 2 places where the IPv6DualStack=true flag are being appended to the commands that are being ran. That flag has been deprecated in Kubernetes 1.25 and it is prohibiting the services from starting.

Thanks for the report. This feature gate is also set in layer-kubernetes-common for kubelet and kube-proxy, so kubernetes-worker is affected too.

I also submitted a pull request for that project to fix it last night there.

Thanks

Yep, sorry Jeremy, I hadn't seen your PRs before I submitted mine. Ah well.
