在root目錄下
先放好自定義的constants.py
文件再docker run
同時記得修改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 設置環境變量的，
-v, --volume=[host-src:]container-dest[:<options>]: Bind mount a volume.映射與共享用
附： -v選項
運行命令：docker run -it
-v /home/xqh/myimage:/data
ubuntu /bin/bash
其中的 -v 標記 在容器中設置了一個掛載點 /data（就是容器中的一個目錄），並將主機上的 /home/xqh/myimage 目錄中的內容關聯到 /data下。
這樣在容器中對/data目錄下的操作，還是在主機上對/home/xqh/myimage的操作，都是完全實時同步的，因為這兩個目錄實際都是指向主機目錄。
AppRTC 需要三個 Server：
- Room Server: 負責處理加入房間、獲取配置等請求；
- Signal Server: 長連接服務器，用於聊天過程中實時下發信息；
- TURN/STUN Server: 打洞服務器，用於 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;
注意一定要開放 3478 udp 端口，否則 STUN Binding 請求進不去
；
AppRTC Android demo 中，會嘗試從房間配置中讀取
pc_config
域，以取得 TURN/STUN Server 信息；如果沒有獲取到，就會向配置中的
ice_server_url
指向的服務器獲取 TURN/STUN Server 信息。但 apprtc 的配置說明中，讓我們把 TURN/STUN Server 配置寫在
TURN_SERVER_OVERRIDE
中，這是不行的，因為客戶端的邏輯並不會讀取
TURN_SERVER_OVERRIDE
這個域，此外 Android demo 讀取
pc_config
的代碼中，無法正確把 TURN Server 的用戶名解析出來，所以我們不得不自己搭一個
ICE Server
，這會多一次網絡請求
示例的constants.py:
ICE_SERVER_BASE_URL, ICE_SERVER_URL_TEMPLATE and WSS_INSTANCES
has been modified.
因此我們還需要第四個 Server：ICE Server。它用於下發 TURN/STUN Server 配置信息，代碼如下
幾點說明：
- 這里面有兩個配置寫死了：key = '4080218913'，用戶名 ninefingers，它們都是在部署 Coturn 時配置的；
- username/credential 並不是 Coturn 創建用戶的 username/password，而是按照上述邏輯計算出來的值，否則 Coturn 會報錯 401 Unauthorized；
- 上面的 ICE Server 部署之后，Android demo 請求時會報 404，最終定位是因為 demo 用 HttpURLConnection 時設置了 connection.setDoOutput(true);，注釋掉就好了，詳見這個 commit；
