docker-maven-plugin不创建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时，它没有创建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时。它可以成功运行，没有任何错误，但不会生成Dockerfile。看一下发送到屏幕上的消息，尽管插件是在“build”中配置的，但看起来并不像是运行的。

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。下面是当我运行它时向屏幕发出的消息：

Answer 1

你可能需要运行"maven package docker:build“而不仅仅是"maven package”。为了将docker构建绑定到maven阶段，您还可以尝试如下所示：

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

您可能还需要使用dockerfile-maven-plugin而不是docker-maven-plugin(当前处于非活动状态)

  <artifactId>dockerfile-maven-plugin</artifactId>
