PS：请注意本体不在有 NoSchedule 节点，答案变成 3 个
Set configuration context $ kubectl config use-context k8s
Check to see how many nodes are ready (not including nodes tainted NoSchedule) and write the number to /opt/nodenum
答案
kubectl describe node |grep -i taints |grep -v -i noschedule
echo $Num > /opt/KUSC00402/kusc00402.txt或者：
# for i in `kubectl get nodes|grep Ready|grep -v 'NAME'|awk '{print $1}'` ;
do
kubectl describe node $i |grep Taints|grep -v 'NoSchedule';
done|wc -l >/opt/nodenum
# cat /opt/nodenum
