0.概念：Helm作为一个包管理工具, 它把Kubernetes资源(比如deployments、services或 ingress等) 打包到一个chart中，方便我们将其chart保存到chart仓库用来存储和分享
1.服务端安装：
curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get > get_helm.sh
chmod 700 get_helm.sh
./get_helm.sh
2.客户端安装
wget https://storage.googleapis.com/kubernetes-helm/helm-v2.10.0-linux-amd64.tar.gz
tar -zxf helm-v2.10.0-linux-amd64.tar.gz
mv linux-amd64/helm /usr/local/bin/
3.使用记录
[root@pserver78 site2powerone]# helm list #列出所有kubernetes部署
interested-chipmunk 1 Wed Dec 12 19:27:31 2018 DEPLOYED site2powerone-0.1.0 default
helm delete interested-chipmunk --purge # 删除部署
3.3 创建新的chart
helm create site3powerone
3.4 cat values.yaml
[root@pserver78 site2powerone]# cat values.yaml |egrep -v '#|^$'
