Question

我正在尝试为安装和部署阶段中构建和推送的maven Java项目提供docker镜像;我希望用当前的git commit id标记这些图像。

我遇到的问题是，maven-git-commit-plugin似乎无法正确导出${git.commit.id.abbrev}变量以供docker-maven-plugin消费。

我的父母pom.xml是这样的：

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </pluginManagement>

        <plugins>

    </build>
</project>

我的插件是我的模块pom.xml的一部分：

        <plugin>
            <groupId>com.spotify</groupId>
            <artifactId>docker-maven-plugin</artifactId>
            <configuration>
                <imageName>docker-registry.nexus.bazaarvoice.com/${project.parent.artifactId}-${project.artifactId}:${git.commit.id.abbrev}</imageName>
                <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>
                <!-- copy the service's jar file from target into the root directory of the image -->
                <resources>
                    <resource>
                        <targetPath>/</targetPath>
                        <directory>${project.build.directory}</directory>
                        <include>${project.build.finalName}.jar</include>
                    </resource>
                    <resource>
                        <targetPath>config</targetPath>
                        <directory>${project.parent.basedir}/deploy/config/${project.artifactId}</directory>
                        <include>*</include>
                    </resource>
                </resources>
            </configuration>
        </plugin>

我收到以下错误：

[ERROR] Failed to execute goal com.spotify:docker-maven-plugin:0.3.8:build (docker-build) on project service: Exception caught: The template variable 'git.commit.id.abbrev' has no value -> [Help 1]

我尝试切换到buildnumber-plugin，但我遇到了同样的错误（使用${buildNumber}代替${git.commit.id.abbrev}）。

我缺少什么？在git commit id插件设置变量之前，docker插件是否正在执行？

我有一个类似的问题，因为我直接调用插件（我没有绑定我的pom中的插件阶段，所以我必须明确地调用它）：

mvn -f myModule/pom.xml docker:build -DforceTags -DpushImage

使用插件conf：

  <plugin>
    <groupId>com.spotify</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <configuration>
        <imageName>registry/myModule</imageName>
        <imageTags>
            <imageTag>${project.version}</imageTag>
            <imageTag>latest</imageTag>
            <imageTag>${git.commit.id.abbrev}</imageTag>
        </imageTags>
        <baseImage>java</baseImage>
        <entryPoint>
            ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/${project.build.finalName}.jar"]
        </entryPoint>
        <resources>
            <resource>
                <targetPath>/</targetPath>
                <directory>${project.build.directory}</directory>
                <include>${project.build.finalName}.jar</include>
            </resource>
        </resources>
    </configuration>
</plugin>

由于maven-git-commit-plugin绑定到初始化阶段，我必须调用该阶段，以便git插件填充属性

mvn initialize -f myModule/pom.xml docker:build -DforceTags -DpushImage

Answer 2

尝试使用 mvn package docker:build 代替 mvn docker:build

如何在gven中将git commit id用作docker image标记？
