How to setup Scalelite load balanacer for BigBlueButton

I am trying out the BigBlueButton web conferencing system and would like to say it is amazing. So far I have set up a standalone BigBlueButton server with SSL and have configured Greenlight to work with it too. My moodle deployment also is integrated with BigBlueButton.

Now I am trying to scale out my BigBlueButton deployment by adding 3 or more BigBlueButton servers so I can handle more than 150 simultaneous users and for that purpose I have to setup Scalelite, the recommended load-balancer for BigBlueButton.

The part where I am confused is the setup of the PostgreSQL database and Redis cache as the docs aren’t very clear about their setup. I am reaching out here so that someone who has some experience in setting up a Scalelite load-balancer can help me out.

Do the PostgreSQL and Redis need to be setup as Docker containers themselves? Furthermore, do they have to be on a system external to the Scaleleite server? If they do, how would the docker container for Scalelite connect with PostgreSQL and Redis when they are on an external system?
