使用 dockerfile-maven-plugin 标记创建的图像

Question

我正在使用具有以下配置的 dockerfile-maven-plugin：

  <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
.
.
.

在构建目标下为存储库添加前缀（以类似于推送目标的方式）解决了这个问题。但是本地创建的图像以存储库标签为前缀。

未找到有关如何在推送任务之前执行标记的任何文档参考。

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

向我的配置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>

Answer 2

您还可以在使用

成功构建后手动标记图像

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

Answer 3

即使会使用现有的 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，我们仅标记并推送。

<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>
