一、配置命令自动补全
yum install -y bash-completion
source /usr/share/bash-completion/bash_completion
source <(kubectl completion bash)
echo "source <(kubectl completion bash)" >> ~/.bashrc
二、彻底卸载K8S集群
yum remove -y kubelet kubeadm kubectl
kubeadm reset -f
modprobe -r ipip
lsmod
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
三、卸载docker
yum remove containerd.io.x86_64 docker-ce.x86_64 docker-ce-cli.x86_64 docker-cerootless-extras.x86_64
docker-scan-plugin.x86_64
8.检测是否删除成功
yum list installed | grep docker
docker version
