可以使用kubeadm config配置此行为。您是否尝试过使用-pod网络cidr字符串。官方文件中的更多详细信息关于配置节点ip以通过kubeadm配置文件传递给kubelet的有用说明： 根据和一些实验，它应该位于节点注册部分示例的kubeletExtraArgs下，使用配置文件中的IP：

pod网络cidr仅适用于非主机网络pod。我正在寻找hostnetwork pod IP tho。对不起，我没有理解，这其实很奇怪，你的kube api清单是什么样子的。你能添加这些细节吗？在问题中添加了更多细节。谢谢。到目前为止，配置看起来不错，您是否可以添加ps aux | grep kubelet输出。我想看看kubelet配置是否有问题。
