本地jar包上传docker容器

　　先安装docker的注册服务器：

[root@VM_0_7_centos ~]# docker run -d -p 5000:5000 --restart=always --name registry2 registry:2

　　开启docker远程api：

[root@VM_0_7_centos ~]# vi /usr/lib/systemd/system/docker.service

　　原来文件描述符fd方式改为tcp，指定端口2375：

 　　让docker支持http上传镜像文件（我们本地的jar包）：

[root@VM_0_7_centos ~]# echo '{ "insecure-registries":["110.111.119.10:5000"] }' > /etc/docker/daemon.json

　　注意：这里的110.111.119.10是你docker所在服务器的ip。

　　重启docker：

[root@VM_0_7_centos ~]# systemctl daemon-reload && systemctl restart docker

　　本地jar包的pom文件引入docker插件：

                    <baseImage>java:8</baseImage>
                    <entryPoint>["java", "-jar", "-Dspring.profiles.active=prod","/${project.build.finalName}.jar"]
                    </entryPoint>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>
        </plugins>
    </build>

　　注意：dockerHost的ip就是docker所在服务器的ip，端口号是2375。直接跑maven：
