Docker<四>开放远程连接，idea打包上传镜像启动服务

1. 开放docker远程访问：
   vi /lib/systemd/system/docker.service
   在ExecStart=/usr/bin/dockerd -H 后面添加 tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

2. 刷新配置，重启服务：
   systemctl daemon-reload
   systemctl restart docker
   docker start registry
3. idea pox.xml中配置：

    <build>
        <finalName>app</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
            </plugin>
            <!--docker的maven插件-->
            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>0.4.13</version>
                <configuration>
                    <!--配置docker的镜像工程-->
                    <imageName>47.95.228.162:5001/${project.artifactId}:${project.version}</imageName>
                    <baseImage>jdk1.8</baseImage>
                    <entryPoint>["java","-jar","/${project.build.finalName}.jar"]</entryPoint>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                    <dockerHost>http://47.95.228.162:2375</dockerHost>
                </configuration>
            </plugin>
        </plugins>
    </build>

3. idea打包上传镜像到服务器：(服务器上docker的远程连接端口一定要开放)
   mvn install
   mvn docker:build -DpushImage
4. 服务器上查看：
   docker images
5. 浏览器查看：
   http://47.95.228.162:5001/v2/_catalog

6. 服务器上启动镜像
   docker run -di --name=wordpress -p 8099:8099 47.95.228.162:5001/wordpressport:0.0.1-SNAPSHOT

7. 查看jar包是否运行

[root@iz2zegpdc9x4o0ir42a2upz ~]# ps -aux|grep .jar
root     224207  0.3 10.5 1470276 107212 ?

已发现app.jar在运行，打开浏览器输入访问接口，测试是否开放了访问端口

8. 查看日志文件
   docker logs -f 容器ID/容器名
   例如： docker logs -f wordpress
