Question: What care must be taken when using this webrtc stack in a docker container? #931

Open themightyoarfish opened 1 year ago

themightyoarfish commented 1 year ago

I have an application which works fine when everything runs locally, or even when the server is remote and the client (browser) local. It's based on the SFU example and forwards rtp data to whatever receivers (browsers) are connected.

Locally, when the client connects, it gets the "server"'s offer and the setup dutifully proceeds

Server got peer SDP: {"id":"127.0.0.1-1dc53f58-9d3d-40e2-a2cb-ba82097e5538","sdp":{"type":"answer","sdp":"v=0\r\no=mozilla...THIS_IS_SDPARTA-99.0 6532382530334643839 0 IN IP4 0.0.0.0\r\ns=-\r\nt=0 0\r\na=sendrecv\r\na=fingerprint:sha-256 C0:8C:1A:99:9B:7D:0E:17:C8:76:0C:74:88:FF:0D:AF:99:DF:38:2B:9A:84:5B:7E:C0:98:92:33:EC:A3:EB:FA\r\na=group:BUNDLE video\r\na=ice-options:trickle\r\na=msid-semantic:WMS *\r\nm=video 9 UDP/TLS/RTP/SAVPF 96\r\nc=IN IP4 0.0.0.0\r\na=recvonly\r\na=fmtp:96 max-fs=12288;max-fr=60\r\na=ice-pwd:a35578e2b114f46e389f147afd2b80c3\r\na=ice-ufrag:d4d97dad\r\na=mid:video\r\na=rtcp-fb:96 nack\r\na=rtcp-fb:96 nack pli\r\na=rtcp-fb:96 goog-remb\r\na=rtcp-mux\r\na=rtpmap:96 VP9/90000\r\na=setup:active\r\na=ssrc:3530259587 cname:{d50322e0-ec5a-4339-adc2-281cd2b9da0f}\r\n"},"method":"answer"}

and eventually, the state changes to failed due to timeout.

So I was wondering what ports would have to be forwarded from inside the container. So far I was mapping these ports

      - "3033:3033"
      - "3478:3478/tcp"
      - "3478:3478/udp"
      - "5349:5349"
      - "59000-59020:59000-59020/udp"

and set 

  config.portRangeBegin = 59000;
  config.portRangeEnd = 59020;

though I'm not sure that's needed. Is there anything else I should be doing?

This is on macos, where docker host networking is not available, I will try this on Linux, but i believe this info would be valuable regardless.

paullouisageneau commented 1 year ago

Docker in the default bridge network mode introduces a NAT between the host address and the container private address. Since you typically run the host itself behind a NAT, if you run a browser on the host, it creates a cascading NAT scenario which may fail depending on the specific setup, and which a STUN server on the public Internet can't help solving as it can't see the host address.

There are multiple approaches to solve this issue:

Strangely, the log excerpt for the failure actually shows an ICE pair nomination, which would correspond to a successful connection.
