使用Spotify Maven插件将Docker推送到Docker Hub

Question

我正在尝试将简单的springboot docker映像推送到私有docker hub存储库，但出现错误。我正在使用 spring-boot-maven-plugin 来执行此操作，并且我希望在运行 mvn deploy

时推送映像

Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy (default-deploy) on project app: Deployment failed: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter -> [Help 1]
[ERROR] 

如何才能在pom中设置存储库参数才能工作？

我的pom：

 <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>

                    <repository>my_username/project_name</repository>

                            <goal>push</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
