Feature Overview (aka. Goal Summary)

IPv6 single stack support for OpenShift Container Platform 4 on GCP

Goals (aka. expected user outcomes)

OpenShift Container Platform 4, IPv6 sinlge stack support is only available on bare-metal and starting with OpenShift Container Platform 4.13 on vSphere. Customers running on GCP are still bound to IPv4 only OpenShift Container Platform 4 - Cluster deployments which exposes some serious limitations for application requiring IPv6.

It's therefore required that OpenShift Container Platform 4 running on GCP also receives support for IPv6 single stack deployments to allow applications which require IPv6 to connect and use OpenShift Container Platform 4 running on GCP.

Requirements and Use cases (aka. Acceptance Criteria):

With more and more enterprise customer moving towards public cloud, their network requirements towards IPv6 does expand into public cloud and thus requires IPv6/IPv4 dual-stack support to remain relevant for application requiring support for both stacks.

Also with the Red Hat provided Cloud Services, enterprises will move workload to those offering and potentially require IPv6 single stack support for newly created application or some specifically IPv6 only application.
