k8s三台机器搭建集群+dashboard

（实验环境默认操作需要关闭防火墙和selinux，这里不详细说明）

常规报错解决方案：

如果集群部署完状态依旧是noready：

执行journalctl -f -u kubelet命令
报错：NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized
或者报错：Unable to update cni config: no valid networks found in /etc/cni/net.d

执行ls /opt/cni/bin/命令，看是否有flannel这个文件，如果没有，就是有问题的

在3台机器上复制flannel到/opt/cni/bin/文件夹，并添加执行权限chomod +x
