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.

For real infrastructure providers, please check the corresponding provider documentation for IPv6 support. Furthermore, please check the documentation of your preferred networking extension for IPv6 support.

Development/Testing 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.

To get started with the IPv6 setup and create a local IPv6 single-stack shoot cluster, run the following commands:

make kind-up gardener-up IPFAMILY=ipv6
k apply -f example/provider-local/shoot-ipv6.yaml

Please also take a look at the guide on Deploying Gardener Locally for more details on setting up an IPv6 gardener for testing or development purposes.

Container Images

If you plan on using custom images, make sure your registry supports IPv6 access.

Check the component checklist for tips concerning container registries and how to handle their IPv6 support.
