Java 如何使用Maven将Spring Boot应用程序的Docker映像推送到DockerHub？

我希望能够将我的Spring Boot应用程序部署到DockerHub。我随后在根项目目录中创建了

Dockerfile

，并修改了我的

pom.xml

文件

Dockerfile

如下所示：

FROM openjdk:8-jre-alpine3.9

COPY target/myproduct-1.0-SNAPSHOT.jar /myproduct.jar

CMD ["java","-jar","/myproduct.jar"]
EXPOSE 8080/tcp

                        </goals>
                        <configuration>
                            <executable>docker</executable>
                            <workingDirectory>${project.basedir}</workingDirectory>
                            <arguments>
                                <argument>push</argument>
                                <argument>${project.groupId}/${project.artifactId}:${project.version}</argument>
                            </arguments>
                        </configuration>

                </executions>
            </plugin>
        </plugins>
    </build>
</project>

因此，我将其添加到

pom.xml

文件中：

<distributionManagement>
    <repository>
        <id>DockerHub</id>
        <name>DockerHub</name>
        <uniqueVersion>false</uniqueVersion>
        <layout>legacy</layout>
        <url>https://index.docker.io/v1/</url>
    </repository>
</distributionManagement>

我想

https://index.docker.io/v1/

是错误的

DockerHub的正确URL模式是什么？

请尝试以下URL：
