docker-maven-plugin打包docker镜像

1、pom插件及其配置

  <plugins>
         
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                                 <mainClass>com.*.common.*.MainApplicatiion</mainClass>
                        </manifest>
                    </archive>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                </configuration>
                <executions>
                    <execution>
                        <id>make-my-jar-with-dependencies</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

            <plugin>

                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source><!-- 源代码使用的开发版本 -->
                    <target>1.8</target><!-- 需要生成的目标class文件的编译版本 -->
                    <!-- 一般而言，target和source保持一致的，但有时候不同：为了让程序能在其他版本的jdk中运行(对于低版本目标jdk，源代码中需要不使用低版本jdk不支持的语法) -->
                </configuration>
            </plugin>

            <!--docker 镜像插件-->
            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>1.2.2</version>
                <configuration>
                    <imageName>${project.artifactId}</imageName>
                    <dockerDirectory>src/main/docker</dockerDirectory>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
<!--                            <include>${project.build.finalName}.jar</include>-->
                            <include>demoApplication-with-dependencies.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>
        </plugins>

2、Dockerfile的编写

# Docker image for springboot file run
# 基础镜像使用java
FROM java:8
# 作者
MAINTAINER jiang <jiang@163.com>
# VOLUME 指定了临时文件目录为/tmp。
# 其效果是在主机 /var/lib/docker 目录下创建了一个临时文件，并链接到容器的/tmp
VOLUME /tmp
# 将jar包添加到容器中并更名为app.jar
ADD  demoApplication-with-dependencies.jar demoApplication.jar
# 运行jar包
RUN bash -c 'touch /app.jar'
ENTRYPOINT java -Djava.security.egd=file:/dev/./urandom -jar /app.jar

3、编辑打包docker镜像

 mvn clean -DskipTests package docker:build

控制台打印日志

4、docker镜像查看

localhost:docker apple$ docker images
REPOSITORY                     TAG       IMAGE ID       CREATED         SIZE
demoApplication            latest    9ede21f0d753   8 minutes ago   737MB
localhost:docker apple$
