com.google.cloud.tools:jib-maven-plugin:1.4.0:dockerBuild 插件离线执行失败

Question

当无法访问在线 docker 注册表以强制仅使用本地资源时，我应该如何设置此 maven 插件？

[ERROR] Failed to execute goal com.google.cloud.tools:jib-maven-plugin:1.4.0:dockerBuild (default-cli) on project mental: registry-1.docker.io: Temporary failure in name resolution: Unknown host registry-1.docker.io: Temporary failure in name resolution -> [Help 1]

插件配置为：

<plugin>
    <groupId>com.google.cloud.tools</groupId>
    <artifactId>jib-maven-plugin</artifactId>
    <configuration>
        <from>
            <image>adoptopenjdk:11-jre-hotspot</image>
        </from>
        <to>
            <image>mental:latest</image>
        </to>
        <container>
            <entrypoint>
                <shell>sh</shell>
                <option>-c</option>
                <arg>chmod +x /entrypoint.sh &amp;&amp; sync &amp;&amp; /entrypoint.sh</arg>
            </entrypoint>
            <ports>
                <port>8080</port>
            </ports>
            <environment>
                <SPRING_OUTPUT_ANSI_ENABLED>ALWAYS</SPRING_OUTPUT_ANSI_ENABLED>
                <JHIPSTER_SLEEP>0</JHIPSTER_SLEEP>
            </environment>
            <useCurrentTimestamp>true</useCurrentTimestamp>
        </container>
    </configuration>
</plugin>

更新。将 jib 插件升级到 1.61 后。并在图像名称前添加 docker://，离线构建工作正常，但我在输出中收到以下错误：

Answer 1

查看配置会有帮助，但您可以通过 <configuration> 指示 jib 使用本地 docker 守护进程作为图像的来源，方法是在图像名称前加上 docker://，如下所示（顺便说一句，需要插件版本 1.6.0+）：

<configuration>
  <from>
    <image>docker://openjdk:alpine</image>
  </from>
  <!-- ... -->
</configuration>
