别靠近k8s集群，会带来不幸

一、卸载k8s

1. 卸载containerd

    sudo apt-get purge   --auto-remove containerd.io
   

2. reset集群

   sudo su
   kubeadm reset -f
   

3. 卸载k8s

   sudo apt-get purge   --auto-remove kubernetes-cni
   sudo apt-get purge --auto-remove kubeadm
   sudo apt-get purge --auto-remove kubectl
   sudo apt-get purge --auto-remove kubelet
   

4. 删除文件

   sudo su
   modprobe -r ipip
   rm -rf ~/.kube/
   rm -rf /etc/kubernetes/
   rm -rf /etc/systemd/system/kubelet.service.d
   rm -rf /etc/systemd/system/kubelet.service
   rm -rf /usr/bin/kube*
   rm -rf /etc/cni
   rm -rf /opt/cni
   rm -rf /var/lib/etcd
   rm -rf /var/etcd
   apt clean all
   apt remove kube*
   

5. 利用dpkg命令查看是否还有k8s其他服务

   dpkg -l | grep kube
   

6. 如果有，则执行以下命令删除，替换kube_name成软件名字

   sudo apt-get purge   --auto-remove kuber_name
   find / -name kube* -delete
   find / -name kube* | xargs rm -rf
   find / -name kube* | xargs rmdir
   

7. 重启

二、卸载docker

sudo apt-get autoremove docker docker-ce docker-engine  docker.io  containerd runc
dpkg -l | grep docker
sudo apt-get autoremove docker-ce-*
sudo rm -rf /etc/systemd/system/docker.service.d
sudo rm -rf /var/lib/docker
docker --version
