查看污点，可以使用以下命令

kubectl describe nodes k8s-master |grep Taints
Taints:             gameble=true:NoSchedule[root@k8s-master ~]# kubectl describe nodes k8s-node1 | grep Taints
Taints:             drunk=true:NoSchedule[root@k8s-master ~]# kubectl describe nodes k8s-node2 | grep Taints 
Taints:             smke=true:NoSchedule

删除污点，根据上边命令查出来的污点名来删。

gameble-
gameble就是污点名，后加减号就删掉了

[root@k8s-master ~]# kubectl taint node k8s-master gameble-
node/k8s-master untainted[root@k8s-master ~]# kubectl taint node k8s-node1 drunk-
node/k8s-node1 untainted[root@k8s-master ~]# kubectl taint node k8s-node2 smke-
node/k8s-node2 untainted
