XMPP Server - Prosody

[djxx]

@girish - As far as I know, all ports except 5280 don't serve HTTP - they're just TCP traffic. The 5280 port is just for some modules, one of which is a "status" module I planned to use for the required healthcheck endpoint. I did my best to put the data in the manifest file, but honestly I got the port information from here: https://github.com/SaraSmiseth/prosody#ports

As for the bare domain, yes - it just needs the cert. It won't actually communicate through this domain; It relies on SRV DNS records to point XMPP clients to the sub-domain that is actually serving XMPP: https://github.com/SaraSmiseth/prosody#dns

It's possible some of these ports and domains could be consolidated - but there will for sure be more than one domain, port, and cert needed to set XMPP up properly.

@djxx Ah ok, then this requires the platform feature to set up DNS when using TCP ports. Currently, we support this via aliases only when using HTTP.

But this shouldn't be a blocker because one can anyway put these DNS entries manually (for now, till we have all the requirements charted out).

Also, for your initial problem of not having the certs of the bare domain - just add the bare domain as an alias . You can do this by setting "multiDomain": true in the manifest. Once you do that the tls addon should provide with the cert as well.

[djxx]

@girish Thanks. Does enabling multiDomain result in the cert requested from Lets Encrypt using alternate names, or does it put multiple certs into /etc/certs ? Also, is there a way to specify the multiple domains in the manifest - or does it need to be done manually after the application is set up? This could make installation difficult if we need to partially start the application, then add some domain entries, and then do another action to complete the application's setup.

I went ahead and tried it, and I do see two certs now:

• tls_cert.pem
• xmpp.mydomain.com.cert

But both of these have CN and alternate name set to: *.mydomain.com and are the exact same cert.

https://docs.trueelena.org/self_hosting/modern_xmpp_server/index.html has some XMPP setup . I haven't read through that in close detail.

Will investigate when I find some time

@girish Any update on this? I'd like to be able to keep tinkering on this before I forget all the prosody and cloudron stuff I crammed in my head

[girish]

@djxx can only look into this after Christmas

@djxx - thank you for doing this difficult work and helping Cloudron support XMPP.

I hope that we are able to make Prosody an officially supported application soon. Maybe your write up of the packaging experience will help others who might want to try supporting ejabberd.

Most people say ejabberd is tricky for configuration. I think that supporting it on Cloudron is one way to accomplish all that effort and make it available with one click.

Well done!

Peertube has a chat plugin. One of the options is for XMPP Prosody:

[djxx]

Hello - any update on this? A standalone app is still needed; even though some apps like Jitsi use XMPP internally (like Jitsi) it doesn't mean it's useful for general external usage.

@djxx check the VoceChat custom app install in the meantime.

That's not really comparable to an XMPP server.

[robi]

@jdaviescoates Neither is Jitsi.

[jdaviescoates]

@robi no one said it was (@djxx just mentioned Jitsi uses it, whilst pointing out that isn't useful and an standalone XMPP server is still needed)

[girish]

@djxx haven't worked on this yet.

[LoudLemur]

Prosody would help integrate with Peertube too: the Peertube livechat plugin uses Prosody:

[djxx]

@girish - any update? I see you guys shipped 8.0, congrats! I'm looking at moving servers again and no XMPP is a deal breaker for me at the moment.

I know the feeling! We lose a lot if we suspend focus on a project for a while.

[girish]

@djxx Is https://github.com/DerekJarvis/cloudron-prosody still the latest code? We should have some free cycles coming up, so I thought we can take a look if this is something easily doable. I can't promise we will publish it since it seems quite complicated (it's why we had to remove Jitsi too, it became way too hard to fight their system). Was the cert issue the blocker for you to just use your custom image yourself?
