由 Google Jib 和 Maven 构建的 Docker 映像的多个标签？

Question

使用jib-maven-plugin 我想构建一个带有多个标签的图像。虽然mvn jib:build 基本上可以正常工作，但它“只”用latest 标记图像。

我的 Maven pom.xml 定义如下：

<plugin>
    <groupId>com.google.cloud.tools</groupId>
    <artifactId>jib-maven-plugin</artifactId>
    <version>2.8.0</version>
    <configuration>
        <to>
            <image>my-private-registry.org/my-image</image>
        </to>
    </configuration>
</plugin>

The docs 表明可以在 XML 中使用jib.to.tags 来定义标签列表。但是，我想在 Jenkins 管道中运行构建步骤，即我无法对 pom.xml 中的标签进行硬编码。

是否可以在运行mvn 命令时传递标签列表，例如通过设置一些-D 参数？

使用-Djib.to.tags=a,b,c。

$ mvn package jib:build -Djib.to.tags=a,b,c
