由Google Jib和Maven构建的Docker镜像的多个标签？

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基本上工作得很好，但它“只”用latest标记图像。

我的Maven pom.xml定义了以下内容：

<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展示了可以在XML中使用jib.to.tags来定义标记列表。但是，我想在Jenkins管道中运行构建步骤，即我不能在pom.xml中对标记进行硬编码。

在运行mvn命令时，是否可以通过设置一些-D参数来传递标记列表？

使用-Djib.to.tags=a,b,c。

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