Installation Steps

1. Prepare Docker Compose

1. Copy the template:

   cp docker-compose.template.yml docker-compose.yml
   

2. Edit docker-compose.yml to fit your environment.
3. Use Let's Encrypt and Certbot for SSL certificates. Replace YOUR.DOMAIN in docker-compose.yml with your actual domain name.

2. Configure TURN Server

1. Copy the template:

   cp turnserver.template.conf turnserver.conf
   

2. Edit turnserver.conf:

   • Replace YOUR.DOMAIN.NAME with your domain.
   • Replace YOUR.USERNAME and YOUR.PASSWORD with your credentials.

   Example:

   server-name=example.com
   realm=example.com
   user=username:password
   

3. Verify Files

Ensure turnserver.conf and docker-compose.yml are in the same directory.

4. Start the Server

Run:

docker-compose up -d

5. Check Logs (Optional)

Check logs to verify the server:

docker-compose logs -f

Notes

• Open ports (e.g., 3478, 5349 for TURN) on your firewall.
