I had AI look at this, but it wasn't very fruitful. It suggests using Cloudron's wildcards and, for Prosody, using its ACME plugin which can obtain certificates:"Let's dive into the specific technical challenges and potential solutions for using Prosody on Cloudron:
Domain Flexibility with Prosody:
Prosody is indeed more flexible than Snikket in this regard. You can configure Prosody to use different domains for XMPP addresses and the web portal. The key configuration options you'd need to focus on are:
VirtualHost "example.com"
-- XMPP domain configuration
http_host = "chat.example.com"
-- Web interface domain
This separation isn't possible with Snikket's current setup.
Certificate Handling:
The core issue here is obtaining a certificate for example.com when your Cloudron app is hosted at chat.example.com. Prosody itself doesn't solve this, but there are potential workarounds:
a) Use Cloudron's wildcard certificate: If Cloudron provides a wildcard cert for *.example.com, you could use this for both the chat subdomain and the main domain.
b) Manual certificate injection: You could manually obtain a certificate for example.com and inject it into the Prosody container. This would require modifying the Cloudron app to allow for custom certificate paths:
ssl = {
certificate = "/path/to/custom/fullchain.pem";
key = "/path/to/custom/privkey.pem";
}
c) ACME plugin: Prosody has an ACME plugin that can obtain certificates. You'd need to ensure the Cloudron app has the necessary permissions to write these certificates and that the DNS challenge is used instead of HTTP:
plugin_paths = { "/usr/lib/prosody/modules" }
modules_enabled = {
"acme"
}
acme = {
provider = "letsencrypt",
challenge = "dns-01"
}
SRV Records:
Cloudron should allow you to set custom DNS records. You'd need to add:
_xmpp-client._tcp.example.com. IN SRV 0 5 5222 chat.example.com.
_xmpp-server._tcp.example.com. IN SRV 0 5 5269 chat.example.com.
Cloudron Integration:
The existing GitHub repo is a start, but you'd need to modify it to:
Allow for custom domain configuration
Implement one of the certificate solutions mentioned above
Possibly add a script to automatically update SRV records via Cloudron's API
Reducing Overhead:
Unlike Snikket, Prosody doesn't include a TURN/STUN server by default. You could either:
a) Use an external TURN/STUN service
b) Implement a lightweight TURN/STUN server as a separate Cloudron app
To move forward:
Fork the existing Cloudron-Prosody repo and start implementing these changes.
Engage with Cloudron's development team about adding an option for apps to use the primary domain certificate. This would solve many of these issues at the platform level.
Consider implementing a custom module for Prosody that interfaces with Cloudron's API for dynamic configuration and certificate management.
This approach should address the specific technical challenges you're facing with implementing an XMPP server on Cloudron while taking advantage of Prosody's flexibility. The key will be integrating Prosody's configurability with Cloudron's app structure and API."
