通过maven插件构建docker镜像:
    1、在pom.xml 中添加maven的docker插件。
         <plugin>
            <groupId>com.spotify</groupId>
            <artifactId>docker-maven-plugin</artifactId>
            <version>0.4.13</version>
            <configuration>
                <imageName>jingdata/microservice-discovery-eureka:0.0.1</imageName>
                <baseImage>java</baseImage>
                <entryPoint>["java","-jar","/{project.build.finalName}.jar"]</entryPoint>
                <resources>
                    <resource>
                        <targetPath>/</targetPath>
                        <directory>${project.build.directory}</directory>
                        <include>${project.build.finalName}.jar</include>
                    </resource>
                </resources>
            </configuration>
        </plugin>
        
  2、构建docker镜像:  mvn  clean   package   docker:build
  3、执行docker images 查看刚构建的镜像
  4、启动镜像:  docker  run -d -p  8761:8761  jingdata/microservice-discovery-eureka:0.0.1
  5、访问测试:  128.0.0.1:8761 
  

插件读取dockerfile进行构建:

  1、在src/main目录下,新建文件夹docker,在文件夹中新建一个Dockerfile文件。
      FROM java:8
      VOLUME /tmp
      ADD  microservice-discovery-erueka-0.0.1-SNAPSHOT.jar   app.jar 
      RUN  bash   -c  'touch /app.jar'
      EXPOSE  9000
      ENTRYPOINT  ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
      修改pom.xml文件:
       <plugin>
            <groupId>com.spotify</groupId>
            <artifactId>docker-maven-plugin</artifactId>
            <version>0.4.13</version>
            <configuration>
                <imageName>jingdata/microservice-discovery-eureka:0.0.2</imageName>
                <dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory>
                <resources>
                    <resource>
                        <targetPath>/</targetPath>
                        <directory>${project.build.directory}</directory>
                        <include>${project.build.finalName}.jar</include>
                    </resource>
                </resources>
            </configuration>
        </plugin>
        
  2.将插件绑定在没某个phase执行
       <plugin>
            <groupId>com.spotify</groupId>
            <artifactId>docker-maven-plugin</artifactId>
            <version>0.4.13</version>
            <executions>
                <execution>
                    <id>build-image</id>
                    <phase>package</phase>
                    <goals>
                        <goal>build</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <imageName>jingdata/microservice-discovery-eureka:0.0.3</imageName>
                <baseImage>java</baseImage>
                <entryPoint>["java","-jar","/${project.build.finalName}.jar"]</entryPoint>
                <resources>
                    <resource>
                        <targetPath>/</targetPath>
                        <directory>${project.build.directory}</directory>
                        <include>${project.build.finalName}.jar</include>
                    </resource>
                </resources>
            </configuration>
        </plugin>      
  
  3.推送镜像
    (1)、修改maven的全局配置文件settings.xml,在其中添加docker hub的用户信息。
          <server>
              <id>docker-hub</id>
              <username>docker-hub的用户名</username>
              <password>docker-hub的密码</password>
              <configuration>
                <email>docker-hub的邮箱</email>
              </configuration>
          </server> 
    (2)、修改pom.xml文件
        <plugin>
            <groupId>com.spotify</groupId>
            <artifactId>docker-maven-plugin</artifactId>
            <version>0.4.13</version>
            <configuration>
                <imageName>jingdata/microservice-discovery-eureka:0.0.4</imageName>
                <baseImage>java</baseImage>
                <entryPoint>["java","-jar","/{project.build.finalName}.jar"]</entryPoint>
                <resources>
                    <resource>
                        <targetPath>/</targetPath>
                        <directory>${project.build.directory}</directory>
                        <include>${project.build.finalName}.jar</include>
                    </resource>
                </resources>
                
                <!-- 与maven配置文件settings中配置的server id一致,用于推送镜像--->
                <serverId>docker-hub</serverId>
            </configuration>
        </plugin>
   (3)、添加pushImage标示,推送镜像
          mvn clean package docker:build  -DpushImage
          
   (4)、推送到私有仓库地址:
          <imageName>localhost:5000/jingdata/microservice-discovery-eureka:0.0.4</imageName>
