Hardcoded prosody port in mod_c2s.lua

[jmallach]

After changing the default XMPP_PORT to '5223', prosody was still trying to use 5222 in addition to 5223:

jitsi-prosody-1   jitsi/prosody:stable-9457-2   "/init"   prosody   16 minutes ago   Up 8 minutes    5222-5223/tcp, 5269/tcp, 5280/tcp, 5347/tcp

After inspecting the container, it looks like the jitsi prosody container has a hardcoded value for the default port, which does not use XMPP_PORT at all:

root@1b30451b8a46:/# rgrep 5222 /lib/prosody/
/lib/prosody/modules/mod_c2s.lua:       default_port = 5222;

In this setup, there's a Jitsi stack already running in parallel, using port 5222 for prosody, which is why I need to change it.

This results in jvb and jicofo being very unhappy:

Am I doing anything wrong, or is it really a hardcoded value for 5222/tcp?

Ops, that might need to be templated, do you want to send a PR?

[jmallach]

I would have, but where on earth does the prosody container come from? I have not been able to find it. :sweat_smile: Gràcies!

Here it is: https://github.com/jitsi/docker-jitsi-meet/tree/master/prosody

Ah, sorry, I knew about this after all: so I just need to template under rootfs/lib/prosody, I assume.

Correct!
