Multiple LiveStreaming instances with chat and REDIS

[LoicBonavent]

Hello, I wanted to use multiple LiveStreaming instances, with chat enabled, on a specific server (Example : ls.univ.fr) : not on BigBlueButton server and not on the Web server. With such a configuration for each instance, I was unable to connect to each instance from the chat page on the Web server :

• BBB_ENABLE_CHAT=true
• BBB_REDIS_HOST=redis (different for each instance)
• BBB_REDIS_CHANNEL=chat
• BBB_CHAT_NAME=Chat

The only solution I found (perhaps there is another solution in this case ?) is to use the port number for REDIS host. For each LiveStreaming instance, I set on docker-compose.yml : redis: image: redis command: --port 6379 (6380 for the 2°, 6381 for the 3°...) ports:

• '6379:6379' (6380 for the 2°, 6381 for the 3°...) bbb-streamer: ...
  • BBB_ENABLE_CHAT=true
  • BBB_REDIS_HOST=redis
  • BBB_REDIS_CHANNEL=chat
  • BBB_CHAT_NAME=Chat

Then, on my chat page on the Web server, to publish the message, I used the following code (Python) : r = redis.Redis(host='ls.univ.fr', port=6379, db=0) r.publish('chat', message) The port depends on which LiveStreamins is used.

At present, this solution only works for the first instance (on default port 6379). If it's possible to add the port as a parameter and modify chat.py on the line 93, this solution will work in all case 👍 : redis_r = redis.Redis(host=args.redis,charset="utf-8", decode_responses=True) =>For example : redis_r = redis.Redis(host=args.redis,port=args.port,charset="utf-8", decode_responses=True)

Is it possible ?

Thx

Hello,

Finally I found a solution without modification on bbb-liveStreaming. I play with configuration for each instance. In the first instance, I put these parameters : redis: image: redis ports:

• "6379:6379" ... bbb-streamer :
• BBB_REDIS_HOST=redis
• BBB_REDIS_CHANNEL=chat1

For the second instance : redis: image: redis ports:

• "6380:6379" ... bbb-streamer :
• BBB_REDIS_HOST=redis
• BBB_REDIS_CHANNEL=chat2 etc

The trick is to use an unique REDIS channel, and to redirect port (Example: 6380) to an unique container port 6379.

After, in my chat page, on the Web server (not on the same server), I connect to REDIS :

• by hostname (Example : ls.univ.fr)
• by port number (Example: 6379 for the first, 6380 for the second...) and publish on specific channel (Example: chat1 for the first, chat2 for the second...)

Hope this helps someone.
