 使用上面列出的方法之一正确地设置网络(网络是在 kubeadm 之外设置的)，您可以使用 kubeadm 向集群添加 Windows 节点。在较高的级别上，首先必须使用 kubeadm(Linux) 初始化主节点，然后设置基于 CNI 的网络(在 kubeadm 之外)，最后开始将 Windows 或 Linux 工作节点连接到集群。如需其他文件和参考资料，请访问上文的 kubeadm 链接。

 and your networking is setup correctly using one of the methods listed above (networking is setup outside of kubeadm), you can use kubeadm to add a Windows node to your cluster. At a high level, you first have to initialize the master with kubeadm (Linux), then set up the CNI based networking (outside of kubeadm), and finally start joining Windows or Linux worker nodes to the cluster. For additional documentation and reference material, visit the kubeadm link above.
