## README

### 一、yaml文件夹
> 主要是部署 jenkins 中使用到的 .sh 脚本文件和 yaml 文件

### 二、其他材料可参考 [https://github.com/wangchirl](https://github.com/wangchirl)

### 三、三个分支
- master 分支
> 针对首次使用 流水线 Jenkinsfile 部署的情况
- release 分支
> 针对多项目流水线 Jenkinsfile 部署的情况
- latest 分支
> K8S 动态扩缩容项目构建
>- 创建参数 branch 、project_name
>- 配置凭证 github/gitee/gitlab 、harbor、k8s
>>- github & harbor：使用用户名密码的方式
>>- k8s ：使用 Kubernetes configure > cat /root/.kube/config
>- 每个微服务创建 deploy.yml 配置文件
>- 修改微服务中 application.yml 配置
