User Story:

The MCO should set the default value for KUBELET_NODE_IPS (for example, 0.0.0.0 or ::/0) when dualstack is enabled. This value is then passed to --node-ip flag of kubelet, which enables it to set an initial node IP internal address.

If left empty, kubelet will not set the node IP address, leading to a CNI failure chain, where ovn-kubernetes fails to start.

Acceptance Criteria:

Description of criteria:

• KUBELET_NODE_IPS is default to unspecified address for cloud providers.

(optional) Out of Scope:
