Control Plane IPV6 Address

I have a client that is coming from a IPV6 only environment trying to interact with GKE.  Does the Control plane have a V6 address? I have V6 connectivity enabled in my cluster, all the nodes have a dual stack address, as well as the pods being created but I don't see a way of obtaining a V6 address for the control plane.  

Is there some setting I've missed?

Hey csgeek,

at this time there are no options to configure the GKE control plane address range to use ipv6.

One possible workaround is to configure an ingress, that acts as an endpoint for the client to reach the cluster. The ingress automatically deploy a load balancer, and some GCP load balancer support ipv6 termination (https://cloud.google.com/load-balancing/docs/ipv6). So the ipv6 client call the load balancer to reach the cluster, the lb terminate the ipv6 connection and initiate an ipv4 connection the the backend (the cluster).

I've never tried this, but hope it can be helpfull

Amato
