Enable IPv6 networking

PX-CSI supports IPv6 networking for Kubernetes deployments with Pure Storage FlashArray. This page provides guidance on supported platforms and known limitations. Use this information to ensure compatibility and optimal functionality in environments that require IPv6.

  • Portworx supports IPv6 on Red Hat OpenShift versions 4.15 or later on bare metal.
  • IPv6 networking isn't supported when installing Portworx behind a proxy.
  • For OpenShift Virtualization, PX-CSI supports IPv6 only in dual-stack networking mode.

By default, Portworx uses IPv6 if the network interfaces it uses (such as dataInterface and mgmtInterface) are configured with only an IPv6 address.

If the host uses a dual-stack configuration, you must explicitly configure Portworx to use IPv6. To configure IPv6 as the preferred network IP address, set the following environment variable field in the StorageCluster specification:

env:
  - name: PX_PREFER_IPV6_NETWORK_IP
    value: "true"
