我们以微服务发现测试demo为例，打包并构建微服务发现镜像。实现docker镜像构建需要准备docker环境，这里就不在赘述了。通过docker方式可以快速实现微服务的发布和部署，使得开发和部署不再复杂而繁琐。单体应用的整体维护容易引入bug而微服务只需要对存在bug的服务模块进行修复不影响其它模块的运行，虽然很多情况下考虑微服务会带来维护成本的增加，但是在开发运维一体化的实践过程中，“开发即运维”工作高度统一也就无足轻重了，因为我们有更多的时间去关注代码。
Maven打出可运行的jar包
找到项目主路径使用mvn命令打包：
mvn install
打包后可以在target下找到相应的jar包：
我们在centos中创建一个microservcice目录并上传jar包：
mkdir microservcicecd microservcicerz microservice-discovery-eureka-0.0.1-SNAPSHOT.jar
Dockerfile文件的创建和编辑
在microservcice路径下使用vi编辑Dockerfile并创建文件：
vi Dockerfile
Dockerfile的内容如下：
# 基于哪个镜像FROM java:8# 将本地文件夹挂载到当前容器VOLUME /tmp# 拷贝文件到容器，也可以直接写成ADD microservice-discovery-eureka-0.0.1-SNAPSHOT.jar /app.jarADD microservice-discovery-eureka-0.0.1-SNAPSHOT.jar app.jarRUN bash -c 'touch /app.jar'# 开放8761端口EXPOSE 8761# 配置容器启动后执行的命令ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
注：为使镜像文件不至于过大所以基础镜像不采用任何Unix镜像而直接用就JDK镜像。
