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

<?xml version="1.0" encoding="UTF‐8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema‐instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
[url]http://maven.apache.org/xsd/maven[/url]‐4.0.0.xsd">
<parent>
<artifactId>xc‐framework‐parent</artifactId>
<groupId>com.xuecheng</groupId>
<version>1.0‐SNAPSHOT</version>
<relativePath>../xc‐framework‐parent/pom.xml</relativePath>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>xc‐govern‐center</artifactId>
<version>1.0‐SNAPSHOT</version>
<dependencies>

<artifactId>spring‐cloud‐starter‐netflix‐eureka‐server</artifactId>
</dependency>
</dependencies>
<build>

<plugin>

<artifactId>docker‐maven‐plugin</artifactId>
<version>1.0.0</version>
<!‐‐docker镜像相关的配置信息‐‐>
<configuration>
<!‐‐镜像名，这里用工程名‐‐>
<imageName>${project.artifactId}‐${project.version}</imageName>
<!‐‐Dockerfile文件所在目录‐‐>
<dockerDirectory>${project.basedir}/src/main/resources</dockerDirectory>
<!‐‐TAG,这里用工程版本号‐‐>
<imageTags>
<imageTag>${project.version}</imageTag>
</imageTags>
<imageName>${project.artifactId}:${project.version}</imageName>
<!‐‐构建镜像的配置信息‐‐>
<resources>
<resource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.artifactId}‐${project.version}.jar</include>
</resource>
</resources>
</configuration>
</plugin>
</plugins>
</build>
</project>

2、将Dockerfifile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

mvn ‐f pom_docker.xml clean package ‐DskipTests docker:build

创建镜像成功，结果如下：
