The cluster example use random ports for mapping to the host machine. You can see the mapped ports with docker-compose ps.

Yes, I see that the ports are randomized.
That said, how does one connect to the XMPP server after issuing the docker-compose scale command ?

Sorry for the delay. In this example I just demonstrate how to extend the container image to setup an ejabberd cluster. For production, you could use i.e. haproxy to route the traffic to the container.

I close this. Fell free to open this issue if you still have problems with the docker-compose cluster example. Maybe I'll extend the example some day with a working proxy setup.

This is example was working for me at some point in the past, but now I'm having issues getting the different Ejabberd containers to actually talk to each other. While the cli output looks successful, the ejabberdctl ping call from the second node never actually returns anything other than pang.
Here is some slightly abridged output (sorry for how huge it is):

FWIW it seems to be something messed up with ejabebrdctl ping, as just running the command to join the cluster seems to be working fine. I opened an issue with Ejabberd here for anyone else having this problem processone/ejabberd#797
from docker-ejabberd.

Just for future people reading this issue, this was also a problem for me: processone/ejabberd#805
