前言

最终效果展示

搭建

准备工作

• 一台有公网ip的Linux服务器

• 一个域名（可选）

• 我搭建的环境为
• Ubuntu 22.04
• Docker Engine - Community 25.0.2

启动服务

version: '3.6'
services:
  # 直播流媒体服务器

      - "3333:3333/tcp" # ws协议
      - "3334:3334/tcp" # wss协议，加密传输
      - "3478:3478/tcp" # WebRTC TURN
      - "10000-10009:10000-10009/udp" # WebRTC Candidate

    restart: always
    volumes:
      - ./cert/:/cert # 证书目录
      # - ./config:/opt/ovenmediaengine/bin/origin_conf # 配置目录 第一次启动先注释掉，因为我们没有默认的配置文件
      
  # 直播客户端， 先注释，之后会说明
  # radium:
  #   container_name: radium
  #   ports:
  #     - "3000:3000"
  #   environment:
  #     - BASE_URL=# 写你的域名或ip，例如127.0.0.1:3000
  #     - INITIAL_SOURCE_TYPE=webrtc
  #     - INITIAL_SOURCE_URL=# 这里写webrtc协议拉流地址，之后会说明
  #   image: ghcr.io/zibbp/radium:next

配置多个推流地址

WebRTC推流 - 使用网页进行直播

version: "3.3"

services:
  webrtc:

    container_name: "website"
    ports:
      - 8079:80
    restart: unless-stopped
    environment:
      # Note: those envs are customizable but also optional
      - SERVER_ROOT=/var/public
      - SERVER_CONFIG_FILE=/etc/config.toml
    volumes:
      - ./static:/var/public # 把你的静态网页路径映射到容器里
      - ./config.toml:/etc/config.toml
