# 7 配置模板pod #

Jenkins 的 kubernetes-plugin 在执行构建时会在 kubernetes 集群中自动创建一个 Pod，并在 Pod 内部创建一个名为 jnlp 的容器，该容器会连接 Jenkins 并运行 Agent 程序，形成一个 Jenkins 的 Master 和 Slave 架构，然后 Slave 会执行构建脚本进行构建。

## 7.1 安装插件 ##

## 7.3 测试 ##

创建pipeline项目：

node('test-rosh')  { 
    
         stage('拉取代码') { 
            echo "拉取代码完成"
        }
    
        stage('制作镜像,上传harbor'){ 
            
            echo "制作镜像 完成"
        }
    
        stage('代码审查'){ 
            echo "代码审查 完成"
        }
     
       stage('远程部署'){ 
          echo "远程部署 完成"
        }      
    }
