每一种方法

#!/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
sudo umount $m||true
done
sudo rm -rf /var/lib/rancher/

#删除/run/kubernetes/ 目录
sudo rm -rf /run/kubernetes/

#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
