docker-maven-plugin Dockerfile 方式簡單應用

插件座標

groupId ：com.spotify
artifactId : docker-maven-plugin
version : 1.2.2

maven 使用方式

    <build>
        <finalName>${artifactId}</finalName>
        <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>1.2.2</version>
                <configuration>
                    <imageName>order-api</imageName>
					<!-- 
                        指定 Dockerfile 所在的文件目錄
                     -->
                    <dockerDirectory>${project.basedir}</dockerDirectory>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>
        </plugins>
    </build>
