我目前在CI中使用jenkins
1）查看github的代码
2）进行静态分析
3）建立jar文件
4）创建docker文件并创建docker image
5）将docker文件推送到私有docker注册表
我有三个微服务，我发现每个jenkins作业运行时，它会在jenkins服务器上创建图像，成本为1.8 GB。

用于单个微服务的Docker文件
FROM java:8
VOLUME /tmp
ADD Mission/target/Mission.jar missionfinal.jar
RUN bash -c 'touch /missionfinal.jar'
EXPOSE 8081
ENTRYPOINT ["java","-Dspring.data.mongodb.uri=mongodb://mongodb/microservices", "-Djava.security.egd=file:/dev/./urandom","-jar","/missionfinal.jar"]
现在我有16 GB的图像并且它将会增长，这只是一个POC，我无法想象它们如何为数百个微服务做。
是一个简单的解决方案，一旦将它推送到存储库，就会从jenkins服务器中删除它吗？任何其他提示和建议，以改善这一过程。
感谢。
