To configure firewall rules for WebSocket ports in Docker, follow these steps:
1. Docker Compose Configuration
1. Expose the WebSocket Port:- In your `docker-compose.yml` file, expose the WebSocket port:
yaml
services:
websockets:
image: beyondcode/laravel-websockets
ports:
- "6001:6001"
2. Firewall Configuration
1. UFW Configuration:- If you are using Ubuntu-based systems, use UFW to configure the firewall:
bash
sudo ufw allow 6001
sudo ufw enable
2. Firewalld Configuration:
- If you are using RHEL-based systems, use firewalld to configure the firewall:
bash
sudo firewall-cmd --add-port=6001/tcp --permanent
sudo firewall-cmd --reload
3. iptables Configuration:
- If you are using older systems, use iptables to configure the firewall:
bash
sudo iptables -A INPUT -p tcp --dport 6001 -j ACCEPT
sudo service iptables save
sudo service iptables restart
3. Verify Firewall Rules
1. Verify Firewall Rules:- Verify that the firewall rules are correctly configured:
bash
sudo ufw status
sudo firewall-cmd --list-all
sudo iptables -nL
4. Monitor WebSocket Connections
1. Monitor WebSocket Connections:- Monitor WebSocket connections to ensure they are functioning correctly:
bash
wscat -c ws://localhost:6001
5. Keep Firewall Rules Up-to-Date
1. Keep Firewall Rules Up-to-Date:- Regularly review and update firewall rules to ensure they remain secure and compliant with best practices.
By following these steps, you can ensure that your WebSocket ports are properly configured and secured within your Docker setup.
