第一步：需要在springboot 项目中增加

pom

            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>0.4.13</version>
                <configuration>
                    <!--镜像名：建议 仓库仓库地址 + 镜像文件夹 + 项目名字-->
                    <imageName>10.100.20.243:8003/duoyuanhua/${project.artifactId}</imageName>
                    <!--dockerfile 所在地址-->
                    <dockerDirectory>src/main/docker</dockerDirectory>
                    <!--仓库仓库地址-->
                    <dockerHost>http://10.100.20.243:8003</dockerHost>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <!--镜像文件夹-->
                            <directory>duoyuanhua</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>

 

 dockerfile

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ADD marketing-1.0-SNAPSHOT.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]

 

执行命令：

mvn clean package docker:build -Dmaven.test.skip=true

报错：

需要去docker开通tcp传输：

vim /usr/lib/systemd/system/docker.service

 

 

-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

 

保存，在重启docker 

systemctl daemon-reload //重新读取配置文件
systemctl restart docker //重新启动服务
lsof -i:2375 // 查看2375端口是否开启
netstat antlp | grep 2375 // 也可以查看

再次执行打包：

mvn clean package docker:build -Dmaven.test.skip=true
