I have 3 Ubuntu VMs where all of them have 2 interfaces. One interface with v4 address and other with both v4 and v6 address. 3 VMs are reachable from each other on all 3 (2 v4 and 1 v6) addresses.
I'm trying to install Kubernetes Cluster with Calico where I need both pod and service IPs should be dual stack supported. I searched and tried a lot - IPv4-only works fine. Any mix of IPv6 fails in kube-proxy, or kube-dns or calico.
I'm posting a question here to ask whether any fellow administrator have installation procedure for kubernetes with IPv6 (Calico).
