【好玩的开源项目】使用Docker部署briefing视频聊天系统

一、briefing介绍

• briefing简介

briefing是一个开源的、安全的直接视频群聊平台。

二、本地环境介绍

2.1 本地环境规划

本次实践为个人测试环境，操作系统版本为centos7.6。

hostname	IP地址	操作系统版本	Docker版本
dokcer	192.168.3.166	centos 7.6	2 20.10.17

2.2 本次实践介绍

1.本次实践部署环境为个人测试环境，生产环境请谨慎；
2.在Docker环境下部署briefing视频聊天系统。

三、本地环境检查

3.1 检查Docker服务状态

检查Docker服务是否正常运行，确保Docker正常运行。

[root@jeven ~]# systemctl status docker
● docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)
   Active: active (running) since Thu 2023-12-21 18:58:04 CST; 3 days ago
     Docs: https://docs.docker.com
 Main PID: 11425 (dockerd)
    Tasks: 47
   Memory: 387.3M
   CGroup: /system.slice/docker.service
           ├─11425 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

3.2 检查Docker版本

检查Docker版本

[root@jeven ~]# docker -v
Docker version 20.10.17, build 100c701

3.3 检查docker compose 版本

检查Docker compose版本，确保2.0以上版本。

[root@jeven ~]# docker compose version
Docker Compose version v2.6.0

四、下载briefing镜像

从docker hub拉取briefing镜像

[root@jeven nullboard]# docker pull holtwick/briefing
Using default tag: latest
latest: Pulling from holtwick/briefing
661ff4d9561e: Pull complete
89059ca18a98: Pull complete

Status: Downloaded newer image for holtwick/briefing:latest
docker.io/holtwick/briefing:latest

五、部署briefing速查表

5.1 使用docker-cli创建briefing容器

使用docker-cli快速部署briefing容器

docker run -d \  \
--name briefing \
-v /datar/briefing/data:/app/data \
-p 6802:8080 \
--restart always \
holtwick/briefing

5.2 创建挂载目录

创建挂载目录

[root@jeven ~]# mkdir -p /data/briefing
[root@jeven ~]# cd /data/briefing/

5.3 编辑docker-compose.yaml文件

本次实践部署使用docker compose方式，编辑docker-compose.yaml文件。

version: '3'

services:
  briefing:
    image: holtwick/briefing
    restart: always
    volumes:
      - /datar/briefing/data:/app/data
    ports:
      - 6802:8080

# networks:
#   default:
#     external:
#       name: proxy

5.4 运行briefing容器

使用docker-compose.yaml文件创建briefing容器

[root@jeven briefing]#  docker compose up -d
[+] Running 2/2
 ? Network briefing_default       Created                                                                               0.0s
 ? Container briefing-briefing-1  Started                                                                               1.2s

5.5 检查briefing容器状态

检查briefing容器状态，确保briefing容器正常启动。

[root@jeven briefing]# docker ps
CONTAINER ID   IMAGE                           COMMAND                  CREATED          STATUS          PORTS                                  NAMES
9c08e1730708   holtwick/briefing               "docker-entrypoint.s…"   39 seconds ago   Up 37 seconds   3478/tcp, 0.0.0.0:6802->8080/tcp, :::6802->8080/tcp   briefing-briefing-1

5.6 检查briefing容器日志

检查briefing容器运行日志，确保briefing服务正常启动。

[root@jeven briefing]# docker logs briefing-briefing-1
Zerva: Vite serving from /app/www

Zerva: *********************************************************
Zerva: Open page at http://localhost:8080
Zerva: *********************************************************

六、配置反向代理

6.1 安装nginx

由于是测试环境，本次反向代理直接部署在本地Docker宿主机同一台服务器上，直接使用yum快速安装nginx。

 yum -y install nginx

启动nginx服务

[root@jeven briefing]# systemctl enable --now nginx
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.

检查nginx服务状态

[root@jeven briefing]# systemctl status nginx
● nginx.service - The nginx HTTP and reverse proxy server
   Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)
   Active: active (running) since Tue 2023-12-26 16:40:11 CST; 24s ago
  Process: 81723 ExecStart=/usr/sbin/nginx (code=exited, status=0/SUCCESS)
  Process: 81720 ExecStartPre=/usr/sbin/nginx -t (code=exited, status=0/SUCCESS)
  Process: 81718 ExecStartPre=/usr/bin/rm -f /run/nginx.pid (code=exited, status=0/SUCCESS)
 Main PID: 81725 (nginx)
    Tasks: 3
   Memory: 2.1M
   CGroup: /system.slice/nginx.service
           ├─81725 nginx: master process /usr/sbin/nginx
           ├─81726 nginx: worker process
           └─81727 nginx: worker process

Dec 26 16:40:10 jeven systemd[1]: Starting The nginx HTTP and reverse proxy server...
Dec 26 16:40:11 jeven nginx[81720]: nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
Dec 26 16:40:11 jeven nginx[81720]: nginx: configuration file /etc/nginx/nginx.conf test is successful
Dec 26 16:40:11 jeven systemd[1]: Started The nginx HTTP and reverse proxy server.

6.2 创建证书相关文件

• 生成私钥

openssl genrsa -out nginx.key 2048

• 生成证书

openssl req -new -key nginx.key -out nginx.csr

openssl x509 -req -in nginx.csr -signkey nginx.key -out nginx.pem

• 检查证书相关文件

[root@jeven briefing]# ls
docker-compose.yaml  nginx.csr  nginx.key  nginx.pem

6.3 修改nginx配置文件

修改nginx配置文件/etc/nginx/nginx.conf

• 备份nginx.conf文件

mv /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bak

• 修改nginx.conf文件，修改位置如图中标注。

 vim /etc/nginx/nginx.conf

        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80

        }
    }

}

6.4 重启nginx服务

重启nginx服务

systemctl restart nginx

七、访问briefing首页

访问地址：https://192.168.3.166/，将IP替换为自己服务器IP地址，进入到briefing首页。如果无法访问，则检查服务器防火墙是否设置，云服务器的安全组端口是否放行等。

将链接地址发送给视频聊天的人员就可以了，这里由于是台式机没有摄像头显示。
