使用maven插件dockerfile-maven-plugin生成Docker镜像并推送到镜像仓库

1.引入maven插件

<build>
    <plugins>
        <plugin>
            <groupId>com.spotify</groupId>
            <artifactId>dockerfile-maven-plugin</artifactId>
            <version>1.3.4</version>
            <executions>
                <execution>
                    <id>default</id>
                    <goals>
                        <goal>build</goal>
                        <goal>push</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <repository>ip地址(push镜像的地址):5000/镜像name</repository>
                <tag>${project.version}</tag>
            </configuration>
        </plugin>
    </plugins>
</build> 

2.在需要生成镜像的maven项目的根目录下载创建Dockfile文件

FROM java:8
MAINTAINER 作者信息
ENTRYPOINT ["java", "-jar", "/app.jar"]
# Add the service itself
ADD target/web-1.0-SNAPSHOT.jar /app.jar

3.使用mvn clean package dockerfile:push命令构建Docker镜像并发送到镜像仓库
