How to build a jvb cluster? High concurrency scenarios！

Install & Config
1

Hi, everyone, I have a question

Host A has a complete jitsi service, and host B only installs jvb. How to connect host B to host A, and how to establish a jvb cluster mode. The purpose is to handle high concurrency scenarios

2

host B needs to use the same config as the jvb on host A, just not to use localhost to connect to prosody, but the IP of host A. Make sure prosody listens on port 5222 on the interface that host B will use to connect to. You only need to make sure both hosts have unique MUC_NICKNAME set in the config.

I configured it according to the tutorial on this webpage, but I did not find the JVB SECRET field in/etc/jitsi/videobridge/config

Cause that field was removed long time ago.
Check the other configs. sip-communicator.properties is the one holding the configuration for connection to the shard by default at the moment.

The IP address of host A is 172.18.0.68, and the IP address of host B is 172.18.0.67. The content of the image is the command I executed on host B
