flaviostutz/coturn repository overview

⁠coturn

COTURN docker container. This is a STUN/TURN server. https://github.com/coturn/coturn⁠

⁠Usage

• Create a docker-compose.yml file

version: "3"

services:

  coturn:
    build: .
    image: flaviostutz/coturn
    network_mode: host
    environment:
      - TURN_USERNAME=coturn
      - TURN_PASSWORD=oursecret

• Run docker-compose up -d

• STUN will accept requests port 3478

⁠ENVs

• PUBLIC_IP - public IP configuration to be used by TURN. If not specified, the public IP will be queried by curl http://icanhazip.com
• TURN_USERNAME - turn server static username. defaults to 'coturn'. if both 'TURN_USERNAME' and 'TURN_PASSWORD' are empty, TURN server will accept anonymous requests
• TURN_PASSWORD - turn server static password for specificed user. defaults to 'oursecret'
• TURN_PORT - turn server port. defaults to '3478'

⁠Considerations

It is advisable to use "network_mode:host" because TURN server will allocate random ports for clients. Currently publishing a wide range of ports in Docker causes too much overhead. With network_mode host it is not the case.

Coturn "realm" is set to "coturn"
