[magnum] [xena] [IPv6] What is needed to make dual-stack IPv4/6 work in Magnum-managed Kubernetes 1.21+?
Hello All,
We run release Xena, and we have deployed Kubernetes version 1.21.10 on Magnum with Fedora CoreOS version 34 and we are trying to have IPv6 support for that Kubernetes cluster, as Kubernetes 1.21 and later versions have dual-stack(IPv4/IPv6) support enabled by default.
To achieve the same, we used a network with both IPv4 and IPv6 subnets and we got a successful creation of the cluster. The compute instances of the cluster get both IPv4 and IPv6 addresses, but the master and minion nodes get IPv4 as external IP, and also the container does not get an IPv6 address.
Can someone please help us with the information, what changes are required to be made at the magnum client-side to have an IPv6 supported Kubernetes Cluster?
Thanks, Namrata

Purely because I happened to be looking at the patches currently pending for Magnum just now, I spotted this one which will be of interest to you:
https://review.opendev.org/c/openstack/magnum/+/802235
It is to add IPv6 support in Magnum. So it appears it isn't currently supported.
Cheers, Andrew
Hi Andrew,
Thanks for the response. The patch you mentioned will make dual-stack IPv4/6 work in Magnum-managed. I will look into this further.
Thanks, Namrata
