由于k8s安装master一直处于NotReady状态查看日志出现 failed to find plugin “flannel” in path [/opt/cni/bin]

查看 /opt/cni/bin 缺少 flannel
查看节点状态
kubectl get nodes
查看日志命令
journalctl -u kubelet -f
解决方案
需要下载CNI插件:CNI plugins v0.8.6
github下载地址:https://github.com/containernetworking/plugins/releases/tag/v0.8.6
(在1.0.0版本后CNI Plugins中没有flannel)
下载后通过xftp 上传到Linux /home目录解压
tar zxvf cni-plugins-linux-amd64-v0.8.6.tgz
复制 flannel 到 /opt/cni/bin/
[root@k8s-node1 home]# cp flannel /opt/cni/bin/
查看节点状态
查看到状态立马变为Ready,至此解决问题。
