IPv6 in Gardener Clusters

🚧 IPv6 networking is currently under development.

IPv6 Single-Stack Networking

GEP-21 proposes IPv6 Single-Stack Support in the local Gardener environment. This documentation will be enhanced while implementing GEP-21, see gardener/gardener#7051.

To use IPv6 single-stack networking, the feature gate IPv6SingleStack must be enabled on gardener-apiserver.

Development Setup

Developing or testing IPv6-related features requires a Linux machine (docker only supports IPv6 on Linux) and native IPv6 connectivity to the internet. If you’re on a different OS or don’t have IPv6 connectivity in your office environment or via your home ISP, make sure to check out gardener-community/dev-box-gcp, which allows you to circumvent these limitations.
