git clone <repository-url>
cd munich-news

# 2. Configure environment
cp backend/.env.example backend/.env
# Edit backend/.env with your settings

# 3. Start system
docker-compose up -d

# 4. View logs
docker-compose logs -f
```

## Environment Configuration

### Required Settings

SMTP_SERVER=smtp.gmail.com
SMTP_PORT=587
EMAIL_USER=your-email@gmail.com
EMAIL_PASSWORD=your-app-password

# MongoDB (Optional - defaults provided)

```

## Production Deployment

### 1. Set MongoDB Password

```bash
export MONGO_PASSWORD=your-secure-password
docker-compose up -d
```

### 2. Use HTTPS for Tracking

Update `backend/.env`:
```env
TRACKING_API_URL=https://yourdomain.com
```

### 3. Configure Log Rotation

Add to `docker-compose.yml`:
```yaml
services:
  crawler:
    logging:
      driver: "json-file"
      options:
        max-size: "10m"
        max-file: "3"
```

### 4. Set Up Backups

```bash
# Daily MongoDB backup
0 3 * * * docker exec munich-news-mongodb mongodump --out=/data/backup/$(date +\%Y\%m\%d)
```

### 5. Enable Backend API

Uncomment backend service in `docker-compose.yml`:
```yaml
backend:
  build:
    context: ./backend
  ports:
    - "5001:5001"
  # ... rest of config
```

## Schedule Configuration

### Change Crawler Time

Edit `news_crawler/scheduled_crawler.py`:
```python
schedule.every().day.at("06:00").do(run_crawler)  # Change time
```

### Change Sender Time

Edit `news_sender/scheduled_sender.py`:
```python
schedule.every().day.at("07:00").do(run_sender)  # Change time
```

Rebuild after changes:
```bash
docker-compose up -d --build
```

## Database Setup

### Add RSS Feeds

```bash
mongosh munich_news

db.rss_feeds.insertMany([
  {
    name: "Süddeutsche Zeitung München",
    url: "https://www.sueddeutsche.de/muenchen/rss",
    active: true
  },
  {
    name: "Merkur München",
    url: "https://www.merkur.de/lokales/muenchen/rss/feed.rss",
    active: true
  }
])
```

### Add Subscribers

```bash
mongosh munich_news

db.subscribers.insertMany([
  {
    email: "user1@example.com",
    active: true,
    tracking_enabled: true,
    subscribed_at: new Date()
  },
  {
    email: "user2@example.com",
    active: true,
    tracking_enabled: true,
    subscribed_at: new Date()
  }
])
```

## Monitoring

### Check Container Status

```bash
docker-compose ps
```

### View Logs

```bash
# All services
docker-compose logs -f

# Specific service
docker-compose logs -f crawler
docker-compose logs -f sender
```

### Check Database

```bash
mongosh munich_news

// Count articles
db.articles.countDocuments()

// Count subscribers
db.subscribers.countDocuments({ active: true })

// View recent articles
db.articles.find().sort({ crawled_at: -1 }).limit(5)
```

## Troubleshooting

### Containers Won't Start

```bash
# Check logs
docker-compose logs

# Rebuild
docker-compose up -d --build

# Reset everything
docker-compose down -v
docker-compose up -d
```

### Crawler Not Finding Articles

```bash
# Check RSS feeds
mongosh munich_news --eval "db.rss_feeds.find({ active: true })"

# Test manually
docker-compose exec crawler python crawler_service.py 5
```

### Newsletter Not Sending

```bash
# Test email
docker-compose exec sender python sender_service.py test your-email@example.com

# Check SMTP config
docker-compose exec sender python -c "from sender_service import Config; print(Config.SMTP_SERVER)"
```

## Maintenance

### Update System

```bash
git pull
docker-compose up -d --build
```

### Backup Database

```bash
docker exec munich-news-mongodb mongodump --out=/data/backup
```

### Clean Old Data

```bash
mongosh munich_news

// Delete articles older than 90 days
db.articles.deleteMany({
  crawled_at: { $lt: new Date(Date.now() - 90*24*60*60*1000) }
})
```
