基于docker的webrtc开发环境
在root目录下
先放好自定义的constants.py
文件再docker run
同时记得修改PUBLIC_IP
可以跨wifi通信
docker
pull piasy/apprtc-server
docker run --name apprtc -p 8080:8080 -p 8089:8089 -p 3478:3478
-p 3478:3478/udp -p 3033:3033 --expose=59000-65000 -e PUBLIC_IP=
47.88.63.197 -v /
root:/apprtc_configs -it piasy/apprtc-server
其中;
-e 设置环境变量的，
-v, --volume=[host-src:]container-dest[:]: Bind mount a volume.映射与共享用
附： -v选项
运行命令：docker run -it
-v /home/xqh/myimage:/data
ubuntu /bin/bash
其中的 -v 标记 在容器中设置了一个挂载点 /data（就是容器中的一个目录），并将主机上的 /home/xqh/myimage 目录中的内容关联到 /data下。
这样在容器中对/data目录下的操作，还是在主机上对/home/xqh/myimage的操作，都是完全实时同步的，因为这两个目录实际都是指向主机目录。
AppRTC 需要三个 Server：
- Room Server: 负责处理加入房间、获取配置等请求；
- Signal Server: 长连接服务器，用于聊天过程中实时下发信息；
- TURN/STUN Server: 打洞服务器，用于 NAT 打洞；
About port expose:
- 8080 is used for room server;
- 8089 is used for signal server;
- 3033 is used for ICE server;
- 3478 and 59000-65000 is used for TURN/STUN server;
注意一定要开放 3478 udp 端口，否则 STUN Binding 请求进不去
；
AppRTC Android demo 中，会尝试从房间配置中读取
pc_config
域，以取得 TURN/STUN Server 信息；如果没有获取到，就会向配置中的
ice_server_url
指向的服务器获取 TURN/STUN Server 信息。但 apprtc 的配置说明中，让我们把 TURN/STUN Server 配置写在
TURN_SERVER_OVERRIDE
中，这是不行的，因为客户端的逻辑并不会读取
TURN_SERVER_OVERRIDE
这个域，此外 Android demo 读取
pc_config
的代码中，无法正确把 TURN Server 的用户名解析出来，所以我们不得不自己搭一个
ICE Server
，这会多一次网络请求
示例的constants.py:
ICE_SERVER_BASE_URL, ICE_SERVER_URL_TEMPLATE and WSS_INSTANCES
has been modified.
因此我们还需要第四个 Server：ICE Server。它用于下发 TURN/STUN Server 配置信息，代码如下
几点说明：
- 这里面有两个配置写死了：key = '4080218913'，用户名 ninefingers，它们都是在部署 Coturn 时配置的；
- username/credential 并不是 Coturn 创建用户的 username/password，而是按照上述逻辑计算出来的值，否则 Coturn 会报错 401 Unauthorized；
- 上面的 ICE Server 部署之后，Android demo 请求时会报 404，最终定位是因为 demo 用 HttpURLConnection 时设置了 connection.setDoOutput(true);，注释掉就好了，详见这个 commit；
附：运行日志
