CORS-4328: configure AWS CCM NodeIPFamilies for dual-stack support #10257
Conversation
Add NodeIPFamilies configuration to AWS cloud provider config when dual-stack networking is enabled. The cloud provider now sets the appropriate IP family ordering (ipv4/ipv6 or ipv6/ipv4) based on the install config's IPFamily setting. For dual-stack IPv4 primary clusters, NodeIPFamilies is set to: NodeIPFamilies=ipv4 NodeIPFamilies=ipv6 For dual-stack IPv6 primary clusters, NodeIPFamilies is set to: NodeIPFamilies=ipv6 NodeIPFamilies=ipv4 Single-stack IPv4 clusters continue to use the minimal config with an empty Global section.

[Global]Note: The installer lays down the correct format. However, CCCMO modifies the format of the
NodeIPFamiliesentries incorrectly in-cluster. The PR openshift/cluster-cloud-controller-manager-operator#426 will fix that.
