Jitsi Video bridge component, prosody, loadbalancing

I’m setting up an auto-scalled loadbalanced environment using jitsi on AWS, it will autoscale jitsi-videobridge instances connecting them to prosody.

I’ve followed this guide: https://github.com/jitsi/jicofo/blob/master/doc/load_balancing.md

am I supposed to create separate components for each individual jitsi-videobridge instance at prosody ? Or am I missing something at the configuration ? If I understand this correctly, you have separate nodes of jitsi-videobridge talking to XMPP server and sending statistics via PUBSUB where Jicofo does the logic behind loadbalancing of these jitsi-videobridges.

Thanks a lot !

When I try to connect the second jitsi-videobridge into prosody I’m getting this error:

Output from JVB:

Just stumbled upon the same problem. For any future visitors do this:

Add the following to your /etc/jitsi/videobrigde/config:

JVB_OPTS="--subdomain=jvb1"

or

JVB_OPTS="--subdomain=jvb2"

respectively.

Add another component to /etc/prosody/conf.d/jitsi.example.com.cfg.lua:

Component "jvb1.jitsi.example.com"
    component_secret = "password"
Component "jvb2.jitsi.example.com"
    component_secret = "password"
