OVN Kubernetes in CNV: IPv6 support for HyperShift

XMLWordPrintable

      • (must-have) HyperShift can be hosted on infra clusters running with IPv6 single-stack networking
      • (must-have) Update KCS https://access.redhat.com/solutions/7011875 explaining that IPv6 single-stack is supported only for HyperShift workloads
      • (???) Should this cover secondary networks too?

      Goal

      Allow customers to host HyperShift-on-KubeVirt clusters on IPv6 single-stack environments.

      User Stories

      • High-Level goal-based user story, with context.
        "As a <VM Owner/Cluster Admin>, I want <to Achieve Some Goal>, so that <Some Reason/Context>."
      • another user story

      Non-Requirements

      • This is limited to HyperShift. To finish this epic, we do not have to make IPv6 single-stack in CNV GA.

      Notes

      To propertly configure ipv6 at VMs from ovn-k we have to configure dhcpv6 stateful (https://www.networkacademy.io/ccna/ipv6/stateful-dhcpv6) with fqdn and override router advertisment src ip address (it will be the default gw) with a new knob at ovn.
