本文介绍了如何使用Jenkins进行Java应用的自动构建，包括构建spring-cloud-demo的镜像文件，通过pipeline查看构建过程，检查构建后的pod，以及在阿里云镜像库中推送的应用镜像。

一、Jenkins.job编译生成spring-cloud-demo的镜像文件

### --- Jenkins.job编译生成spring-cloud-demo的镜像文件

~~~     # 创建完成之后会在k8s中创建一个pod，这个pod就是在pipeline指定的模板文件
~~~     # 执行完成之后这个pod会被清理掉，无论是成功还是失败都会被清理掉
~~~     Jenkins——>spring-cloud-demo——>Build with Parameters——>BRANCH：pipeline-test
~~~     ——>BUILD_COMMAND：mvn clean package-Dskip Tests——>Build——>END

二、查看构建pipeline的blue ocean

三、查看构建的pod

### --- 查看构建的pod

[root@k8s-master01 ~]# kubectl get po -owide
NAME                                     READY   STATUS              RESTARTS   AGE   IP               NODE           NOMINATED NODE   READINESS GATES
spring-cloud-demo-20-3kb3k-z04hq-15hgg   4/4     Running              29s          12s   172.25.244.218   k8s-master01   <none>           <none>

四、查看pipeline构建记录

### --- 查看pipeline构建流水线过程
~~~     Dashboard——>spring-cloud-demo——>1

~~~     # pod构建阶段
