jenkins使用SCM流水线发布K8S

1. 安装 Git Parameter插件

系统管理——插件管理——搜索“Git Parameter”，确认是否已经安装插件，没有安装则先安装插件

2. 创建pipeline类型构建Job

3. 配置分支参数

在General部分、选择参数化构建过程、选择git参数

填写参数信息

4. 配置流水线

代码仓库存放Jenkinsfile文件

代码仓库ruoyi-auth路径下需存在Jenkinsfile文件

    agent any

        REGISTRY= "swr.cn-east-3.myhuaweicloud.com"
