一个月前，我使用 kubeadm 部署了一个 v1.13.0 的 kubernetes 集群，其中有一个主节点和三个工作节点。一切都很好。
但是当我要向这个集群注册一个新的工作人员时。kube-proxy deamonset 容器启动时出现以下错误日志：
W0103 09:41:57.631256 1 proxier.go:477] Failed to load kernel module ip_vs with modprobe. You can ignore this message when kube-proxy is running inside container without mounting /lib/modules

由于 kube-proxy 在容器内，所以主要问题是：

（版本兼容性已被证明不是这个问题的主要原因）
希望有这方面的专家可以帮助我。
