卸载

1、停止相关服务

首先，如果是卸载k8s-1.24以上版本，需要单独卸载containerd
sudo apt-get purge   --auto-remove containerd.io


# 注意顺序
systemctl stop kubelet 
systemctl stop etcd 
systemctl stop docker

2、卸载

kubeadm reset -f

3、删除相关目录

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

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

利用dpkg命令查看是否还有k8s其他服务
dpkg -l |</
