由Google Jib和Maven构建的Docker图像的多个标签

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基本上工作良好；仅"；用CCD_ 3标记图像。

My Mavenpom.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>

文档显示，可以在XML中使用jib.to.tags来定义标记列表。然而，我想在Jenkins管道中运行构建步骤，即我不能硬编码pom.xml中的标记。

运行mvn命令时，是否可以传递标签列表，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

我也有同样的问题，我在pom.xml文件中使用这个片段解决了这个问题：

<plugin>
<groupId>com.google.cloud.tools</groupId>
<artifactId>jib-maven-plugin</artifactId>
<version>${jib-maven-plugin.version}</version>
<configuration>
<from>
<image>${jib-maven-plugin.image}</image>
</from>
<to>
<image>registry.gitlab.com/mygroup/myproject</image>
<tags>
<tag>latest</tag>
<tag>${project.version}</tag>
</tags>
</to>
</configuration>
</plugin>

简单地调用mvn clean package -Pprod verify jib:build将推送latest和pom中定义的项目版本
