</div>

## 📝 Description

Gitea CICD Service is an automated CI/CD (Continuous Integration/Continuous Deployment) solution for projects hosted on Gitea. The system automatically monitors repository events (such as push, pull request) and executes corresponding commands to build, test, and deploy applications.

### 🌟 Key Features

- Automatic triggering on Gitea events (push, pull request)
- Support for multiple environments and technologies (Node.js, Frontend, Backend)
- Email notifications for events
- Flexible configuration through config file
- Nginx integration for webhook handling
- Runs as a systemd service for reliability

## 📁 Directory Structure

```
gitea_CICD/
├── service/                 # Service files directory
│   ├── giteaService.conf    # Configuration template
│   ├── giteaService.sh      # Main script
│   └── giteaHook.service    # Systemd configuration
├── service_run/            # Runtime directory (created during installation)

├── install.sh            # Installation script
└── README.md            # Documentation
```

## 🔧 Customize Build Process

You can customize the build process by adding environment variables in `giteaService.conf`:

```bash
# Syntax:
<name>_PROCESS_PATH=/path/to/directory
<name>_PROCESS_PATH_COMMAND=command1 && command2 ...

# Example:
FE_PROCESS_PATH=/home/project/frontend
FE_PROCESS_PATH_COMMAND=npm install && npm run build

BE_PROCESS_PATH=/home/project/backend
BE_PROCESS_PATH_COMMAND=npm install && npm run start
```

## 📧 Email Notifications

The system sends email notifications when:
- New repository events occur
- Build process succeeds/fails
- Errors occur during processing

## 🔍 Monitoring and Troubleshooting

- View service logs:
```bash
journalctl -u giteaHook -f
```

- Check service status:
```bash
systemctl status giteaHook
```

## 📝 Important Notes

1. The `gitea_CICD` project should be placed at the same level as the project to be monitored
2. Ensure appropriate file and directory permissions
3. Verify environment variables before running the service
4. Use HTTPS for webhooks to ensure security
