com.spotify docker-maven-plugin 0.4.12 spring-boot-docker-start java 8080 ["java", "-jar", "/${project.build.finalName}.jar"] / ${project.build.directory} ${project.build.finalName}.jar
imageName就是镜像的名称。baseImage是基础镜像，本地有使用本地的镜像，没有的话从远程仓库拉取，暴露容器内的8080端口，执行java -jar 命令，启动微服务。我们知道使用Docker需要制定Dockerfile文件，里面的元素完全通过maven插件的标签来体现了。还是有前提的，你得先安装好Docker。讲解到这里，我们开始运行
第一步：执行mvn clean package docker:build创建生成镜像。
第二步：启动镜像docker run -it -P spring-boot-docker-start,看下容器内的日志
➜ spring-boot-docker-start git:(master) docker run -it -P spring-boot-docker-start

第三步：输入docker ps看看容器内的8080端口被映射到了本机的哪个端口
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 075543f8f5b6 spring-boot-docker-start "java -jar /spring..." About a minute ago Up About a minute 0.0.0.0:32768->8080/tcp trusting_noether
确定是32768端口。
第四步：浏览器中输入http://localhost:32768/hello,看到结果
