# 卸载mount目录
for mount in $(mount | grep tmpfs | grep '/var/lib/kubelet' | awk '{ print $3 }') /var/lib/kubelet /var/lib/rancher; do umount $mount; done
 
# 备份目录

# 清理Iptables表
## 注意：如果节点Iptables有特殊配置，以下命令请谨慎操作
sudo iptables --flush
sudo iptables --flush --table nat
sudo iptables --flush --table filter
sudo iptables --table nat --delete-chain
sudo iptables --table filter --delete-chain
 
systemctl restart docker
