3.2.7 停止与删除 
要删除的一个镜像重新创建，需要通过如下步骤：
1、停止正在运行的容器 docker stop 容器名
例如：docker stop xc-govern-center-test 2、删除容器
docker rm 容器名 例如：docker rm xc-govern-center-test 3、删除镜像
docker rmi 镜像名或镜像Id 例如：docker rmi xc-govern-center:1.0-SNAPSHOT
  3.2.8 maven构建镜像 
上边构建的过程是通过手工一步一步完成，maven提供docker-maven-plugin插件可完成从打包到构建镜像、构建 容器等过程。
1、编写pom_docker.xml

2、将Dockerfile文件拷贝到src/main/resource下
3、删除之前创建的xc-govern-center镜像 4、进入工程根目录（pom_docker.xml所在目录）执行
