IPv6 networking with MicroShift
The {product-title} service defaults to IPv4. IPv6 single-stack and IPv4/IPv6 dual-stack networking is available on supported platforms. You configure IPv6 or dual-stack networking in the configuration file.
Consider the following when configuring IPv6 or dual-stack networking with MicroShift:
-
When you set the values for IPv6 in the MicroShift configuration file and restart the service, settings managed by the OVN-Kubernetes network plugin are updated automatically.
-
After migrating to dual-stack networking, both new and existing pods have dual-stack networking enabled.
-
If you require node-wide IPv6 access, such as for the control plane and other services, use the following configuration examples. The MicroShift Multus Container Network Interface (CNI) plugin can enable IPv6 for pods.
-
For dual-stack networking, each MicroShift node network and service network supports up to two values in the node and service network configuration parameters.

Plan for IPv6 before starting MicroShift for the first time. Switching a node to and from different IP families is not supported unless you are migrating a node from default single-stack to dual-stack networking. If you configure your networking for either IPv6 single stack or IPv4/IPv6 dual stack, you must restart application pods and services. Otherwise pods and services remain configured with the default IP family. |
