Configuration

1. Discourse Webhook Setup

  1. Navigate to Admin → API → Webhooks

Payload URL: https://your-domain.com/webhook

Content Type: application/json

2. Telegram Bot Setup

  1. Create bot via @BotFather

  2. Get Chat ID for your group/channel

  3. Optionally set up forum topics for category routing

3. Environment Configuration

4. Docker Deployment


# Quick installation

chmod +x install.sh

./install.sh install

5. Reverse Proxy Setup

For webhook support on your domain, configure reverse proxy (nginx/Apache) to route webhook requests to the bot container on port 8080.

Example nginx configuration:


location /webhook {

proxy_pass http://localhost:8080/webhook;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

}
