Notes on BBB and Associated Servers
Other Dockerization Attempts
There appears to have been some work in the BBB source repo
on Dockerizing the whole BBB system; see the labs/docker
subdirectory.
Servers
Rough overview of servers involved. (Probably lots of inaccuracies
here.) There may be many more; have a look at labs/docker/ in the
source code which lists 14 locally-built images in the README along
with several more pre-built images (greenlight, mongodb, redis) in the
docker-compose.yml.
- nginx: proxy to other servers below
- not Dockerized
- HTTP on ports 80, 443
- BBB: video server
- not Dockerized
- ports ??,??: HTTP API (and human-usable pages?)
- UDP on ports 16384-32768
- mongodb: Used by BBB to synchronize client state
- not Dockerized
- BBB install uses 3.4; probably we can use 3.6 from https://hub.docker.com/_/mongo/
- ports ???
- coturn (optional): TURN and STUN server for NAT traversal
- must be on "separate server" from BBB, with a separate hostname
- port 443 TLS (conflicts with nginx)
- port 3478 TCP/UDP coturn listening port
- ports 49152-65535 UDP for relay
- Greenlight: interface to BBB API
- allows multiple users with different permissions to access different parts of BBB API
- port 127.0.0.1:5000 on host fowarding to port 80 in Docker container
- postgres:9.5
- containerized PostgreSQL used by Greenlight
- 127.0.0.1:5432:5432
