我是如何进行上云的3
kubectl taint nodes node1 key=value:NoSchedule
kubectl taint nodes node1 key=value:NoExecute
kubectl taint nodes node1 key=value:PreferNoSchedule #尽量不调度
NoSchedule:K8Snode添加这个effecf类型污点，新的不能容忍的pod不能再调度过来，但是老的运行在node上不受影响
NoExecute：K8Snode添加这个effecf类型污点，新的不能容忍的pod不能调度过来，老的pod也会被驱逐
PreferNoSchedule：pod会尝试将pod分配到该节点
删除污点
kubectl taint nodes kube11 key:NoSchedule-

解压放入/usr/local/bin
mv linux-amd64/helm /usr/local/bin/helm
使用命令
添加远端仓库(阿里云)
helm repo add apphub https://apphub.aliyuncs.com/
helm repo update
helm repo list
helm repo remove stable(删除远端仓库)
helm search repo nginx查找模板
helm pull apphub/mariadb --version 7.3.9(下载模板)
