Configuring the TURN server for Docker and Podman

You can configure the Sametime Meeting service to enable a TURN server on port 443 for Docker.

The Docker and Podman commands are similar. The only difference is that docker precedes the command when issued in a Docker environment and podman precedes the name in a Podman environment. Example commands used in the Sametime documentation are shown using Docker. For Podman, change docker to podman.

1. Update the following configuration in the custom.env file.

   # Enable TURN for JVB (bridge mode) connections
   TURN_ENABLE=1
   
   # Secret for connect to TURN server
   # Add the same secret that you used to configure TURN server.
   TURN_SECRET=secret
   
   # Announce FQDN/IP address of the turn server via XMPP server (XEP-0215).
   # If empty or not set, variable DOCKER_HOST_ADDRESS will be used by default.
   TURN_HOST=turn.example.com
   
   # TLS/TCP/UDP turn port for connection
   TURN_PORT=443
   
   # Transport for stun/turn connection. Can be tcp or udp.
   TURN_TRANSPORT=tcp
   

2. Add the following configuration to the custom.env file.

   TURN_CREDENTIALS=secret
   

3. Update the following configuration in the .env file.

   GLOBAL_MODULES=turncredentials
   

4. Start the Sametime server to apply the changes.

   docker compose up -d
