Kubernetes 使用kubeadm重新启动群集服务器时重新创建kubelet沙盒错误

当我重新启动主节点和工作节点时，coredns的pod显示以下错误消息，似乎在服务器重新启动后无法重新创建kubelet

您可以尝试清理法兰绒并重新安装

kubectl delete -f https://raw.githubusercontent.com/coreos/flannel/2140ac876ef134e0ed5af15c65e414cf26827915/Documentation/kube-flannel.yml

rm -rf /var/lib/cni/
rm -rf /run/flannel
rm -rf /etc/cni/

移除与法兰和法兰绒相关的接口：

ip link 

对于每个接口法兰，请执行以下操作

ifconfig <name of interface from ip link> down
ip link delete <name of interface from ip link>

要使法兰绒正常工作，必须将--pod network cidr=10.244.0.0/16传递给kubeadm init

是否在不同的cni插件之间切换？flannel是否正在运行？没有切换任何cni插件，flannel正在运行。是否在不同的cni插件之间切换？flannel是否正在运行？没有切换任何cni插件，flannel正在运行。
