Hello!
For now, as I can see, OpenVidu uses Coturn credential mechanism with turnadmin even in docker environment. Is there a problem to generate coturn keys for generated coturn users and to manage them in redis directly?
I’m using openvidu-server v.2.12.0 and because of turnadmin I have had to create solid container with kurento, openvidu and coturn
We use turnadmin because is the easiest way to generate coturn credentials in a redis.
Why don’t you want to use turnadmin? Why you prefer using Java code to do that? Just asking.
In any case, I suppose is perfectly possible as soon as you create users with the format needed by coturn.
Yes, I have found your implementation, and to install an additional coturn in openvidu container to use its turnadmin – that was awesome 
Thanks!
