!/bin/sh

docker rm -f $(docker ps -qa)
docker volume rm $(docker volume ls -q)
cleanupdirs="/var/lib/etcd /etc/kubernetes /etc/cni /opt/cni /var/lib/cni /var/run/calico"
for dir in $cleanupdirs; do
echo "Removing $dir"
rm -rf $dir
done

第二种方法

df -h|grep kubelet |awk -F % '{print $2}'|xargs umount

删除所有容器

sudo docker rm -f $(sudo docker ps -qa)

删除/var/etcd目录

sudo rm -rf /var/etcd

删除/var/lib/kubelet/目录，删除前先卸载

for m in $(sudo tac /proc/mounts | sudo awk '{print $2}'|sudo grep /var/lib/kubelet);do
sudo umount $m||true
done
sudo rm -rf /var/lib/kubelet/

删除/var/lib/rancher/目录，删除前先卸载

for m in $(sudo tac /proc/mounts | sudo awk '{print $2}'|sudo grep /var/lib/rancher);do

done
sudo rm -rf /var/lib/rancher/

删除所有的数据卷

sudo docker volume rm $(sudo docker volume ls -q)

再次显示所有的容器和数据卷，确保没有残留

sudo docker ps -a
sudo docker volume ls

rm /var/lib/kubelet/* -rf

rm /etc/kubernetes/* -rf

rm /var/lib/rancher/* -rf

rm /var/lib/etcd/* -rf

rm /var/lib/cni/* -rf

iptables -F && iptables -t nat -F

ip link del flannel.1

docker ps -a|awk '{print $1}'|xargs docker rm -f

docker volume ls|awk '{print $2}'|xargs docker volume rm
