【问题描述】：
我希望能够将我的 Spring Boot 应用程序部署到 DockerHub。我关注了this tutorial，在项目根目录下创建了Dockerfile，并修改了我的pom.xml文件。
Dockerfile 看起来像这样：
FROM openjdk:8-jre-alpine3.9
COPY target/myproduct-1.0-SNAPSHOT.jar /myproduct.jar
CMD ["java","-jar","/myproduct.jar"]
EXPOSE 8080/tcp
myproduct.jar 是我的应用程序的 JAR 文件。
pom.xml 看起来像这样：
<?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"

当我运行mvn clean install时，镜像在本地Docker上更新，我可以成功启动它。
但是，当我尝试通过运行 mvn clean deploy -Ddocker.user=myusername -Ddocker.password=XXXXXXXX -Ddocker.url=https://hub.docker.com/repository/registry-XXX.docker.io/myusername/myproduct/ -f pom.xml（来自 Idea）将映像部署到 DockerHub 时，我收到以下错误：

所以我将此添加到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>
如this answer 建议的那样。
Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project myproduct: Failed to deploy artifacts: Could not transfer artifact mycompany:myproduct:jar:1.0-20201025.160739-1 from/to DockerHub (https://index.docker.io/v1/): Transfer failed for https://index.docker.io/v1/XXXXXX 405 Not Allowed
我想<url>https://index.docker.io/v1/</url> 是错误的。
DockerHub 的正确 URL 模式是什么？
