maven - 使用 Maven 将 Docker 镜像推送到私有(private)存储库时如何解决身份验证问题

Question

我正在尝试将我在本地使用 maven 构建的 docker 镜像推送到 Docker Cloud/Docker Hub 中的公共(public)/私有(private)存储库。但是当它尝试推送时，我得到的索引响应不包含任何端点。下面是示例我的 pom.xml 的配置。

我不确定我在这里缺少哪个配置。

打开settings.xml为您的 Maven 设置配置并在此处添加带有您的凭据的服务器。通常此文件位于 .m2文件夹，所以在这里添加类似:

<servers>
  <server>
    <id>docker-hub</id>
    <username>username</username>
    <password>password</password>
  </server>
</servers>

pom.xml 中不应有此设置(并且 AFAIK 也不能有)因为安全问题。

如果您对更安全的选项感兴趣，您可以加密您的密码，例如 here .

你太乱了pom.xml .尝试从最简单的 pom.xml 开始配置。查看springio example并更改 springio属性(property)到您的docker hub repo 。

<properties>
   <docker.image.prefix>springio</docker.image.prefix>
</properties>
<build>
    <plugins>
        <plugin>
            <groupId>com.spotify</groupId>
            <artifactId>docker-maven-plugin</artifactId>
            <version>0.4.11</version>
            <configuration>
                <imageName>${docker.image.prefix}/${project.artifactId}</imageName>
                <dockerDirectory>src/main/docker</dockerDirectory>
                <serverId>docker-hub</serverId>
<!--  <registryUrl></registryUrl> is optional and defaults to https://index.docker.io/v1/ in the Spotify docker-client dependency. -->
                <resources>
                    <resource>
                        <targetPath>/</targetPath>
                        <directory>${project.build.directory}</directory>
                        <include>${project.build.finalName}.jar</include>
                    </resource>
                </resources>
            </configuration>
        </plugin>
    </plugins>
</build>
