# 安装Centos #

> [参考自官方流程][Link 1]

*  卸载旧版本
    
        yum remove docker \
                            docker-client \
                            docker-client-latest \
                            docker-common \
                            docker-latest \
                            docker-latest-logrotate \
                            docker-logrotate \
                            docker-engine
 *  安装所需包
    
        sudo yum install -y yum-utils \
            device-mapper-persistent-data \
            lvm2
 *  设置稳定的仓库
    
        sudo yum-config-manager \
          --add-repo \
          https://download.docker.com/linux/centos/docker-ce.repo
 *  安装
    
        sudo yum install docker-ce docker-ce-cli containerd.io
    
    如果控制台提示是否接受GPG密钥，请验证指纹是否匹配 060A 61C5 1B55 8A7F 742B 77AA C52F EB6B 621E 9F35，如果是，则接受。

# Docker远程连接配置 #

*  修改Docker配置：`vi /lib/systemd/system/docker.service`  
    注释原有ExecStart行再添加ExceStart：
    
        ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock --containerd=/run/containerd/containerd.sock
 *  重启Docker并校验(需确保防火墙与ECS已开启2375端口)
    
        systemctl daemon-reload
        systemctl restart docker
        curl 127.0.0.1:2375/info

# Intellij IDEA配置 #

*  **配置Docker连接**

     *  **项目配置打包**  
        主程序QuickApplication ：

            @RequestMapping("/")
            public class QuickApplication {

                    SpringApplication.run(QuickApplication.class, args);
                }
            
                @GetMapping("/hello")
                public ServerResponse hello() {
                    return ServerResponse.success("Hello World");
                }
            }

                        <groupId>org.springframework.boot</groupId>
                        <artifactId>spring-boot-maven-plugin</artifactId>
                    </plugin>
                </plugins>
            </build>
        
        Docker插件运行前需进行项目打包：`mvn package`
     *  **运行Docker插件**

        运行效果图如下(可以看见镜像与容器皆被创建)：![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3oyODEyNjMwOA_size_16_color_FFFFFF_t_70 3]  
        点击Log可以查看容器log:

# 结语 #

虽然Docker可以通过添加CA证书通过https连接提高连接安全性，但这样每个开发者都需要下载CA证书，这显然十分麻烦。实际开发建议通过Jenkins去执行Docker脚本，避免通过外网连接直接操作Docker，具体可参考该文章：[Docker+Jenkins+Nginx+SpringBoot自动化部署项目][Docker_Jenkins_Nginx_SpringBoot]
