maven - docker-maven-plugin 没有创建 dockerfile

Question

我正在使用 docker-maven-plugin 为 Java 微服务创建 dockerfile 和 docker 镜像。当我运行命令 mvn package -DskipTest=true ，它不会创建 Dockerfile。

我正在使用 docker-maven-plugin 为 Java 微服务创建 dockerfile 和 docker 镜像。当我运行命令 mvn package -DskipTest=true .它成功运行，没有任何错误，但它不会生成 Dockerfile。查看发出到屏幕的消息，虽然它是在“构建”中配置的，但它看起来不像该插件运行

以下是 pom.xml 中构建任务的配置:

 <build>
                <plugins>
                        <plugin>
                                <groupId>org.springframework.boot</groupId>
                                <artifactId>spring-boot-maven-plugin</artifactId>
                        </plugin>
            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>1.1.1</version>
                <configuration>
                    <imageName>explorecali-${ec-profile}</imageName>
                    <baseImage>java</baseImage>
                    <entryPoint>["java", "-Dspring.profiles.active=${ec-profile}", "-jar", "/${project.build.finalName}.jar"]</entryPoint>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                    <forceTags>true</forceTags>
                    <buildArgs>
                        <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
                    </buildArgs>
                </configuration>
            </plugin>

        </plugins>
        </build>

没有错误消息，但没有 Dockefile。以下是我运行它时向屏幕发出的消息:

您可能需要运行“maven package docker:build”而不仅仅是“maven package”。为了将 docker build 绑定(bind)到 maven 阶段，您还可以尝试以下操作:

<execution>
<id>build-image</id>
<phase>package</phase>
<goals>
<goal>build</goal>
</goals>
</execution>
