ejabberd - Robust, Scalable and Extensible Realtime Server using XMPP, MQTT and SIP

[opensourced]

ejabberd would be freakin amazing!!

[nebulon]

FYI I took a stab at this two days ago, current state is https://git.cloudron.io/cloudron/ejabberd-app/-/tree/master since I also wanted a XMPP server, however this is quite the beast and I had a hard time so far to figure out the various overlaying ACL and access rules. If anyone has deployed an ejabberd instance in the past, let us know maybe we can work together on this.

@nebulon Have you considered snikket or prosody? They are easier to develop for and run.

snikket

+1 for Snikket

@nebulon what kind of help you might need here?
I'm exploring my options for XMPP server as well, maybe I could be of help here.

Openfire could be an easier option, btw

@LoudLemur interesting, I wonder who @OrcVole is?

[LoudLemur]

Looks like there are a couple of people at ejabberd who are willing to help now, if somebody can contact them. One of them referenced this helm chart for ejabberd:

Has anybody who might know how to package ejabberd contacted the ejabberd people, yet?
