使用dockerfile maven插件标记创建的图像

Question

我正在使用具有以下配置的dockerfile maven插件：

<plugin>
<groupId>com.spotify</groupId>
<artifactId>dockerfile-maven-plugin</artifactId>
<version>1.3.6</version>
<executions>
<execution>
<id>build-image</id>
<goals>
<goal>build</goal>
</goals>
<configuration>
<tag>latest</tag>
<repository>root/${project.artifactId}</repository>
<buildArgs>
<APP_NAME>${project.artifactId}</APP_NAME>
</buildArgs>
</configuration>
</execution>
<execution>
<id>push-image</id>
<goals>
<goal>push</goal>
</goals>
<configuration>
<repository>${docker.registry.url}/root/${project.artifactId}</repository>
</configuration>
</execution>
</executions>
</plugin>

项目部署失败，原因是：

[INFO] The push refers to a repository [my-repository:9090/root/image-name]
[ERROR] An image does not exist locally with the tag: my-repository:9090/root/image-name
[WARNING] An attempt failed, will retry 1 more times
org.apache.maven.plugin.MojoExecutionException: Could not push image
.
.
.

在构建目标下预先设置存储库(类似于推送目标)可以解决问题。但是随后本地创建的带有存储库标记前缀的映像。

没有找到任何关于如何在推送任务之前执行标记的文档参考。

换句话说，我希望我的本地docker图像在插件执行后包含2个图像：

REPOSITORY                                        TAG                 IMAGE ID            CREATED             SIZE
root/image-name                                   latest              7ac1144c607e        21 minutes ago      175MB
my-repository:9090/root/image-name                latest              7ac1144c607e        21 minutes ago      175MB

我的docker版本是：17.06.0-ce

Answer 1

即使使用现有的docker层，我们也不想重新构建。在第一次执行中，我们构建并推送，在第二次执行中我们只标记并推送。

<build>
<plugins>
<plugin>
<groupId>com.spotify</groupId>
<artifactId>dockerfile-maven-plugin</artifactId>
<version>${dockerfile-maven-plugin.version}</version>
<executions>
<execution>
<id>default</id>
<goals>
<goal>build</goal>
<goal>push</goal>
</goals>
<configuration>
<tag>${build.number}</tag>
</configuration>
</execution>
<execution>
<id>default-2</id>
<goals>
<goal>tag</goal>
<goal>push</goal>
</goals>
<configuration>
<tag>latest</tag>
</configuration>
</execution>
</executions>
<configuration>
<repository>${docker-remote.registry}/path/${project.version.lowercase}</repository>
<buildArgs>
<EAR_FILE>${project.build.finalName}.ear</EAR_FILE>
</buildArgs>
<useMavenSettingsForAuth>true</useMavenSettingsForAuth>
</configuration>
</plugin>
</plugins>
</build>

Answer 2

在我的配置中添加额外的执行步骤解决了问题：

<execution>
<id>tag-image</id>
<phase>deploy</phase>
<goals>
<goal>tag</goal>
</goals>
<configuration>
<repository>${docker.registry.url}/root/${project.artifactId}</repository>
</configuration>
</execution>

使用成功构建后，您还可以手动标记图像

mvn dockerfile:tag -Dproject.plugin.dockerfile.tag=my-repository:9090/root/image-name
