使用 docker-maven-plugin

写dockerfile

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ARG JAR_FILE
COPY ${JAR_FILE} /app.jar
ENTRYPOINT ["java", "-jar", "/app.jar"]
EXPOSE 8080

添加pom配置

1.添加properties

        <docker.image.prefix>yang_pack_test</docker.image.prefix>
        <remote-addr>172.24.12.149</remote-addr>

2.添加build

<plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>1.0.0</version>
                <!--将插件绑定在某个phase执行-->
                <executions>
                    <execution>
                        <id>build-image</id>
                        <!--将插件绑定在package这个phase上。也就是说，用户只需执行mvn package ，就会自动执行mvn docker:build-->
                        <phase>package</phase>
                        <goals>
                            <goal>build</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <imageName>${docker.image.prefix}/${project.artifactId}</imageName>
                    <!--指定标签-->
                    <imageTags>
                        <imageTag>latest</imageTag>
                    </imageTags>
                    <!-- 指定 Dockerfile 路径-->
                    <dockerDirectory>${project.basedir}</dockerDirectory>
                    <!--指定远程 docker api地址，需要修改成你自己的ip和端口-->
                    <dockerHost>http://${remote-addr}:2375</dockerHost>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                    <buildArgs>
                        <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
                    </buildArgs>
                </configuration>
            </plugin>
