k8s node 节点加入失败问题请教

This topic created in 2490 days ago, the information mentioned may be changed or developed.

3 台 PC

10.0.0.11 master 已 Ready 10.0.0.12 node1 已 Ready 10.0.0.13 node2 NotReady

奇怪的是 node1 和 node2 安装完全，从同一文档复制粘贴来的，后来又重装了一次也是一样的问题，在 join 以后 node2 上查看 systemctl status kubelet -服务信息，报错为：

Jul 18 15:53:33 node2 kubelet[22013]: W0718 15:53:33.975695 22013 cni.go:213] Unable to update cni config: No networks found in /etc/cni/net.d Jul 18 15:53:38 node2 kubelet[22013]: W0718 15:53:38.976010 22013 cni.go:213] Unable to update cni config: No networks found in /etc/cni/net.d Jul 18 15:53:43 node2 kubelet[22013]: W0718 15:53:43.976326 22013 cni.go:213] Unable to update cni config: No networks found in /etc/cni/net.d

请求大神给与指导，该如何排错

node 上的 cni 网络组件没准备好

[root@node2 kubernetes]# rpm -qa | grep cni
kubernetes-cni-0.7.5-0.x86_64

这个组件是安装的了，应该无需手动配置才对

No networks found in /etc/cni/net.d

正常的应该是这样的

我把 flannel 换用 waeve 组件就好了
