# Docker Setup for Recipe Management App

## MongoDB Configuration

This project now includes a Docker Compose setup for MongoDB with persistent storage.

### Environment Variables

Create a `.env` file in the `backend/` directory with the following variables:

```
# MongoDB Configuration (parameterized for security)
MONGODB_USERNAME=admin
MONGODB_PASSWORD=password123
MONGODB_HOST=localhost
MONGODB_PORT=27017
MONGODB_DATABASE=recipe-management

# Alternative: Use full connection string (overrides individual parameters)
# MONGODB_URI=mongodb://admin:password123@localhost:27017/recipe-management?authSource=admin

# Server Configuration
PORT=5000
```

**Note**: The application will automatically construct the MongoDB URI from the individual parameters. You can also override this by setting `MONGODB_URI` directly.

### Starting the Services

1. Start MongoDB and Mongo Express:
```bash
docker-compose up -d
```

2. Start the backend application:
```bash
cd backend
npm start
```

### Services Included

- **MongoDB**: Database server on port 27017 with persistent volume
- **Mongo Express**: Web-based MongoDB admin interface on port 8081

### Default Credentials

- **MongoDB Admin User**: admin
- **MongoDB Admin Password**: password123
- **Database Name**: recipe-management

### Accessing Services

- **Mongo Express**: http://localhost:8081
- **Backend API**: http://localhost:5000

### Data Persistence

MongoDB data is stored in a Docker volume named `mongodb_data` which persists between container restarts.

### Seed Data

The seed data from `backend/seedData.js` is automatically loaded when the MongoDB container starts for the first time.
