卸载K8S

适用于master和node

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

yum -y remove kubeadm kubectl kubelet
