K8s 集群总是安装失败，记录k8s卸载方式

Docker

1.查看docker状态

systemctl status docker

2.停止docker
如果docker是运行状态，先停调docker。

 systemctl stop docker

3.查看yum安装的docker文件包

 yum list installed |grep docker

删除所有安装的docker文件包

yum -y remove xxx

yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine
 
rm -rf /etc/systemd/system/docker.service.d
rm -rf /var/lib/docker
rm -rf /var/run/docker

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
