> HCloudVIPConfig is a config document to configure virtual IP using Hetzner Cloud APIs for announcement. Virtual IP configuration should be used only on controlplane nodes to provide virtual IP for Kubernetes API server. Any other use cases are not supported and may lead to unexpected behavior. Virtual IP will be announced from only one node at a time using Hetzner Cloud APIs.
