helm 部署 使用 记录

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 '#|^$'
