## Deployment Steps

### 1. Environment Setup
```bash
# Copy and configure environment
cp .env.example .env
nano .env  # Edit with production values
```

### 2. SSL Certificate
```bash
# Install Certbot
sudo apt install certbot python3-certbot-nginx -y

# Obtain certificate
sudo certbot --nginx -d yourdomain.com

# Test auto-renewal
sudo certbot renew --dry-run
```

### 3. Deploy
```bash
# Build and deploy
docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d --build

# Verify
docker compose ps
curl http://localhost/api/health
```

### 4. Verify HTTPS
```bash
# Test redirect
curl -I http://yourdomain.com
# Should return 301 redirect to HTTPS

# Test HTTPS
curl -I https://yourdomain.com
# Should return 200 OK
```

### 5. Monitor
```bash
# Check logs
docker compose logs -f

# Check resource usage
docker stats

# Check disk space
df -h
```

## Post-Deployment Validation

### Functional Tests
- [ ] Homepage loads correctly
- [ ] All navigation links work
- [ ] AI Studio tools functional
- [ ] Document Vault works
- [ ] Project export/import works
- [ ] Multi-language switching works (EN/FR/AR)
- [ ] API health check returns 200

### Security Tests
- [ ] HTTPS redirect works
- [ ] Security headers present (check with curl -I)
- [ ] Rate limiting triggers after 100 requests
- [ ] Invalid API requests return 400
- [ ] Non-existent routes return 404

### Performance Tests
- [ ] Page load < 3 seconds on 3G
- [ ] API response < 500ms (excluding AI generation)
- [ ] Gzip compression active (check Content-Encoding header)
- [ ] Static assets cached (check Cache-Control header)

### Monitoring Tests
- [ ] Health check accessible
- [ ] Logs rotating properly
- [ ] Backup script runs successfully
- [ ] Uptime monitoring receiving pings

## Rollback Procedure

If deployment fails or issues arise:

### 1. Immediate Rollback
```bash
# Stop current deployment
docker compose down

# Revert code
cd /opt/atlasgreen
git checkout <previous-tag>

# Rebuild with previous version
docker compose up -d --build
```

### 2. Verify Rollback
```bash
# Check containers
docker compose ps

# Check logs
docker compose logs -f

# Test functionality
curl http://localhost/api/health
```

### 3. Document Issue
- Record what went wrong
- Document steps taken to resolve
- Update deployment checklist if needed
