KubeIP v2 takes node-level public IP management in Kubernetes to the next level. By supporting GKE, EKS, and OCI, it assigns static public IPs to nodes where necessary (e.g., for gaming or IP whitelisting). Transitioning from a controller to a DaemonSet improves reliability and flexibility. #Kubernetes #CloudNetworking
