卸载k8s, 可以参考这篇文章:https://blog.51cto.com/binghe001/2924757
一共分为以下几步:
1. 删除/etc/kubernetes/文件夹下的所有文件
2. 删除$HOME/.kube文件夹
3. 删除/var/lib/etcd文件夹
rm -rf /etc/kubernetes/*
rm -rf ~/.kube/*
rm -rf /var/lib/etcd/*
4. 停用端口号, 把下面的这些端口号都停用就ok
lsof -i :6443|grep -v "PID"|awk '{print "kill -9",$2}'|sh
lsof -i :10259|grep -v "PID"|awk '{print "kill -9",$2}'|sh
lsof -i :10257|grep -v "PID"|awk '{print "kill -9",$2}'|sh
lsof -i :2379|grep -v "PID"|awk '{print "kill -9",$2}'|sh
lsof -i :2380|grep -v "PID"|awk '{print "kill -9",$2}'|sh
