fabric8 docker-maven-plugin:在构建中包含其他标签 [英] fabric8 docker-maven-plugin: include additional tags on build

问题描述

我在pom.xml中配置了fabric8 docker-maven-plugin，如下所示:

I have the fabric8 docker-maven-plugin configured in my pom.xml as follows:

  <build>
    ...
    <plugins>
      ...
      <plugin>
        <groupId>io.fabric8</groupId>
        <artifactId>docker-maven-plugin</artifactId>
        <version>${docker.plugin.version}</version>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>build</goal>
            </goals>
          </execution>
        </executions>
        <configuration>
          <images>
            <image>
              <name>${docker.image.prefix}/${project.artifactId}:%l</name>
              <build>
                <dockerFile>Dockerfile</dockerFile>
                <assembly>
                  <descriptorRef>artifact</descriptorRef>
                </assembly>
              </build>
            </image>
          </images>
        </configuration>
      </plugin>
      ...
    </plugins>
    ...
  </build>

我正在使用％l 占位符，如果该版本包含 -SNAPSHOT ，则该占位符会使用 latest 标签标记图像，否则它将使用pom版本.从CI进行构建时，我想在图像中添加一些其他标签(可能包括一个以上的标签)(例如，内部版本号/分支名称)，但我想保留％l 占位符行为.我认为应该可以从命令行使用maven属性，但是我无法从插件文档中找到它(https://dmp.fabric8.io/)

I'm using the %l placeholder which tags the image with the latest label if the version contains -SNAPSHOT, otherwise it uses the pom version. When building from CI, I'd like to include some additional tags (possibly more then one) to my image (e.g. build number / branch name) but I'd like to keep %l placeholder behavior. I think that it should be possible using maven properties from command line, but I couldn't figure it out from the plugin docs (https://dmp.fabric8.io/)

在执行docker:build目标时如何添加其他标签?

How can I include additional tags when executing the docker:build goal?

推荐答案

您可以使用< tags> 标签:

https://dmp.fabric8.io/#build-configuration

<properties>
  ...
  <!-- set default -->
  <docker.image-tag>${project.version}</docker.image-tag>
  ...
</properties>


<image>
  ...
  <name>repo/something/%a:%l</name>
  <build>
    ...
    <tags>
      <tag>${docker.image-tag}</tag>
    </tags>
    ...
  </build>
  ...
</image>

这将同时使用％l 行为和自定义设置 $ {docker.image-tag} 标记您的图像.

this will tag your image with both the %l behavior and the custom set ${docker.image-tag}.

mvn docker:build -Ddocker.image-tag=mytag
