```
### Step 3: Deploy with Helm
```bash
helm install dating-app ./helm/dating-app \
-n dating-app \
--create-namespace \
-f my-values.yaml
```
### Step 4: Configure DNS (Optional)
For local access without DNS:
```bash
# Add to /etc/hosts (Linux/Mac) or C:\Windows\System32\drivers\etc\hosts (Windows)
<your-cluster-ip> api.your-lab-domain.local
<your-cluster-ip> app.your-lab-domain.local
```
Or use port forwarding:
```bash
kubectl port-forward -n dating-app svc/frontend 3000:80
kubectl port-forward -n dating-app svc/backend 8000:8000
```
### Monitoring Deployment
```bash
# Watch pods
kubectl get pods -n dating-app -w
# Check events
kubectl get events -n dating-app --sort-by=.metadata.creationTimestamp
# View logs
kubectl logs -n dating-app deployment/backend
kubectl logs -n dating-app deployment/frontend
# Check ingress
kubectl get ingress -n dating-app
kubectl describe ingress -n dating-app
```
## AWS EKS Deployment
### Prerequisites
```bash
# AWS CLI configured
# kubectl installed
# helm installed
# AWS EKS cluster created
# RDS PostgreSQL instance running
# ECR repository created
```
### Step 1: Build and Push to ECR
```bash
# Login to ECR
aws ecr get-login-password --region us-east-1 | \
docker login --username AWS --password-stdin <account>.dkr.ecr.us-east-1.amazonaws.com
# Build and push
ACCOUNT=<your-account-id>
REGION=us-east-1
docker build -t $ACCOUNT.dkr.ecr.$REGION.amazonaws.com/dating-app-backend:v1 backend/
docker push $ACCOUNT.dkr.ecr.$REGION.amazonaws.com/dating-app-backend:v1
docker build -t $ACCOUNT.dkr.ecr.$REGION.amazonaws.com/dating-app-frontend:v1 frontend/
docker push $ACCOUNT.dkr.ecr.$REGION.amazonaws.com/dating-app-frontend:v1
```
### Step 2: Create RDS PostgreSQL
```bash
# Via AWS Console or CLI
aws rds create-db-instance \
--db-instance-identifier dating-app-db \
--db-instance-class db.t3.micro \
--engine postgres \
--master-username dating_user \
--master-user-password <secure-password> \
--allocated-storage 20
```
### Step 3: Prepare Helm Values for AWS
```bash
cp helm/dating-app/values-aws.yaml aws-values.yaml
```
Edit `aws-values.yaml`:
```yaml
backend:
image:
repository: <account>.dkr.ecr.us-east-1.amazonaws.com/dating-app-backend
tag: v1
environment:
DATABASE_URL: postgresql://dating_user:<password>@<rds-endpoint>.rds.amazonaws.com:5432/dating_app
JWT_SECRET: <generate-secure-secret>
CORS_ORIGINS: "https://yourdomain.com,https://api.yourdomain.com"
frontend:
image:
repository: <account>.dkr.ecr.us-east-1.amazonaws.com/dating-app-frontend
tag: v1
environment:
VITE_API_URL: "https://api.yourdomain.com"
backend:
ingress:
host: api.yourdomain.com
frontend:
ingress:
host: yourdomain.com
ingress:
annotations:
alb.ingress.kubernetes.io/certificate-arn: "arn:aws:acm:us-east-1:<account>:certificate/<id>"
```
### Step 4: Deploy to EKS
```bash
# Update kubeconfig
aws eks update-kubeconfig --name <cluster-name> --region us-east-1
# Deploy
helm install dating-app ./helm/dating-app \
-n dating-app \
--create-namespace \
-f aws-values.yaml
# Verify
kubectl get all -n dating-app
```
### Step 5: Configure Route 53
```bash
# Create Route 53 records pointing to ALB DNS name
# Get ALB DNS:
kubectl get ingress -n dating-app -o wide
```
## Upgrading Deployment
### Update Images
```bash
# Build new images
docker build -t $REGISTRY/dating-app-backend:v2 backend/
docker push $REGISTRY/dating-app-backend:v2
# Update values
# In my-values.yaml, change tag: v1 to tag: v2
# Upgrade Helm release
helm upgrade dating-app ./helm/dating-app \
-n dating-app \
-f my-values.yaml
```
### Database Migrations
The backend automatically initializes/migrates the schema on startup.
For manual migrations (if using Alembic in future):
```bash
kubectl exec -it -n dating-app <backend-pod> -- \
alembic upgrade head
```
## Rollback
```bash
# View release history
helm history dating-app -n dating-app
# Rollback to previous version
helm rollback dating-app <revision> -n dating-app
```
## Scaling
### Horizontal Pod Autoscaler (Future Enhancement)
```bash
kubectl autoscale deployment backend -n dating-app \
--min=2 --max=10 --cpu-percent=80
```
### Manual Scaling
```bash
# Scale backend
kubectl scale deployment backend -n dating-app --replicas=3
# Scale frontend
kubectl scale deployment frontend -n dating-app --replicas=3
```
## Backup and Recovery
### PostgreSQL Backup (RDS)
```bash
# AWS handles automated backups. For manual backup:
aws rds create-db-snapshot \
--db-instance-identifier dating-app-db \
--db-snapshot-identifier dating-app-snapshot-$(date +%Y%m%d)
```
### Backup PersistentVolumes
```bash
# Create snapshot of media PVC
kubectl patch pvc backend-media-pvc -n dating-app \
--type merge -p '{"metadata":{"finalizers":["protect"]}}'
```
## Monitoring
### Logs
```bash
# View logs
kubectl logs -n dating-app deployment/backend -f
kubectl logs -n dating-app deployment/frontend -f
# View previous logs if pod crashed
kubectl logs -n dating-app deployment/backend --previous
```
### Resource Usage
```bash
kubectl top pods -n dating-app
kubectl top nodes
```
### Health Checks
```bash
# Check endpoint health
curl http://api.yourdomain.com/health
```
## Troubleshooting
### Pod Won't Start
```bash
# Check events
kubectl describe pod -n dating-app <pod-name>
# Check logs
kubectl logs -n dating-app <pod-name> --previous
```
### Database Connection Issues
```bash
# Test database connectivity
kubectl run -it --rm debug --image=postgres:15-alpine \
--restart=Never -n dating-app -- \
psql -h postgres -U dating_user -d dating_app -c "SELECT 1"
```
### Image Pull Errors
```bash
# Verify image exists in registry
docker pull <your-registry>/dating-app-backend:v1
# Check image pull secret if needed
kubectl create secret docker-registry regcred \
--docker-server=<registry> \
--docker-username=<user> \
--docker-password=<pass> \
-n dating-app
```
## Performance Tuning
### Database Optimization
```sql
-- Create indexes for common queries
CREATE INDEX idx_profiles_created_at ON profiles(created_at DESC);
CREATE INDEX idx_conversations_users ON conversations(user_id_1, user_id_2);
```
### Resource Limits
Adjust in values.yaml based on your infrastructure:
```yaml
resources:
requests:
memory: "512Mi"
cpu: "200m"
limits:
memory: "1Gi"
cpu: "500m"
```
## Security Hardening
### Network Policies
```yaml
# Restrict traffic between pods
kubectl apply -f - <<EOF
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: dating-app-netpol
namespace: dating-app
spec:
podSelector:
matchLabels:
app: backend
policyTypes:
- Ingress
ingress:
- from:
- podSelector:
matchLabels:
app: frontend
ports:
- protocol: TCP
port: 8000
EOF
```
### TLS/SSL
Enable in Ingress with cert-manager:
```yaml
ingress:
annotations:
cert-manager.io/cluster-issuer: "letsencrypt-prod"
```
## Uninstalling
```bash
# Remove Helm release
helm uninstall dating-app -n dating-app
# Remove namespace
kubectl delete namespace dating-app
```

## Backend Architecture
### Core Components
**app/db.py** - Database Connection
- SimpleConnectionPool for connection management
- Auto-initialization of tables on startup
- Safe context manager for connections
**app/config.py** - Configuration Management
- Environment variable loading with defaults
- Settings validation
- Centralized config source
**app/auth/** - Authentication
- `utils.py`: Password hashing (bcrypt), JWT creation/validation
- `__init__.py`: Authorization dependency for FastAPI
**app/models/** - Database Models
- Pure Python classes representing database entities
- User, Profile, Photo, Like, Conversation, Message
- to_dict() methods for serialization
**app/schemas/** - Pydantic Schemas
- Request/response validation
- Type hints and documentation
- Automatic OpenAPI schema generation
**app/services/** - Business Logic
- `auth_service.py`: Registration, login
- `profile_service.py`: Profile CRUD, discovery
- `photo_service.py`: Upload, storage, deletion
- `like_service.py`: Like tracking, match detection
- `chat_service.py`: Message operations, conversations
**app/routers/** - API Endpoints
- Modular organization by feature
- Protected endpoints with `get_current_user` dependency
- Consistent error handling
### Database Design
#### users table
```sql
id (PK), email (UNIQUE), hashed_password, created_at, updated_at
```
#### profiles table
```sql
id (PK), user_id (FK UNIQUE), display_name, age, gender,
location, bio, interests (JSONB), created_at, updated_at
```
#### photos table
```sql
id (PK), profile_id (FK), file_path, display_order, created_at
```
#### likes table
```sql
id (PK), liker_id (FK), liked_id (FK), created_at
UNIQUE(liker_id, liked_id)
```
#### conversations table
```sql
id (PK), user_id_1 (FK), user_id_2 (FK), created_at, updated_at
UNIQUE(user_id_1, user_id_2)
```
#### messages table
```sql
id (PK), conversation_id (FK), sender_id (FK), content, created_at
```
### Key Design Decisions
1. **Synchronous psycopg2** - Per requirements, enables simpler debugging
2. **Connection Pooling** - SimpleConnectionPool provides basic pooling
3. **Auto-initialization** - Tables created on startup, no separate migration step
4. **JWT Tokens** - Stateless auth, no session storage needed
5. **Local File Storage** - Disk-based for lab, easily swappable to S3
6. **Match Logic** - Dual-directional like check in database
### Adding New Features
**Example: Add "message read receipts"**
1. Add schema to `app/schemas/message.py`:
```python
class MessageResponse(BaseModel):
# ... existing fields ...
read_at: Optional[str] = None
```
2. Update database in `app/db.py`:
```python
cur.execute("""
ALTER TABLE messages ADD COLUMN read_at TIMESTAMP
""")
```
3. Add method to `app/services/chat_service.py`:
```python
@staticmethod
def mark_message_read(message_id: int):
# Implementation
```
4. Add endpoint to `app/routers/chat.py`:
```python
@router.patch("/messages/{message_id}/read")
def mark_read(message_id: int, current_user: dict = Depends(get_current_user)):
# Implementation
```
## Frontend Architecture

└── index.css # Global CSS
```
### API Client Pattern
**src/api.js** provides:
- Axios instance with base configuration
- Request interceptor for JWT token injection
- Response interceptor for 401 handling
- Organized API methods by feature:
- authAPI.register(), authAPI.login()
- profileAPI.getMyProfile(), profileAPI.discoverProfiles()
- etc.
**Usage in components:**
```javascript
import { profileAPI } from '../api'
const response = await profileAPI.getMyProfile()
const profiles = await profileAPI.discoverProfiles()
```
### State Management
**Simple localStorage approach:**
- JWT stored in localStorage, auto-attached to requests
- User ID stored for context
- Component-level state with useState for forms
- No Redux/MobX needed for MVP
**Example:**
```javascript
// After login
localStorage.setItem('token', response.data.access_token)
localStorage.setItem('user_id', response.data.user_id)
// On API calls
// Automatically added by axios interceptor
Authorization: `Bearer ${token}`
// On logout
localStorage.removeItem('token')
localStorage.removeItem('user_id')
```
### Component Patterns
**Page Component Template:**
```jsx
export default function FeaturePage() {
const [data, setData] = useState([])
const [isLoading, setIsLoading] = useState(false)
const [error, setError] = useState('')
useEffect(() => {
loadData()
}, [])
const loadData = async () => {
try {
setIsLoading(true)
const response = await featureAPI.getData()
setData(response.data)
} catch (err) {
setError(err.response?.data?.detail || 'Error')
} finally {
setIsLoading(false)
}
}
return (
<div className="feature-page">
{error && <div className="error-message">{error}</div>}
{/* JSX */}
</div>
)
}
```
### Styling Approach
- CSS modules for component isolation
- Global styles in index.css and App.css
- BEM naming convention for clarity
- Mobile-responsive with flexbox/grid
### Environment Configuration
Frontend uses Vite's import.meta.env:
```javascript
// In src/api.js
const API_BASE_URL = import.meta.env.VITE_API_URL || 'http://localhost:8000'
```
In `frontend/.env`:
```
VITE_API_URL=http://localhost:8000
```
## Docker Build Process
### Backend Dockerfile
```dockerfile
# Multi-stage not needed
# Single stage with Python 3.11
# System dependencies: gcc, postgresql-client
# Python dependencies: fastapi, uvicorn, etc.
# Health check via /health endpoint
# CMD: uvicorn main:app
```
### Frontend Dockerfile
```dockerfile
# Multi-stage: builder + runtime
# Stage 1: Build with Node
# - npm install
# - npm run build -> dist/
# Stage 2: Runtime with nginx
# - nginx:alpine
# - Copy dist to /usr/share/nginx/html
# - Custom nginx.conf for SPA routing
# - Health check via /health endpoint
```
### Nginx Configuration
Handles:
- SPA routing: try_files fallback to index.html
- Static file caching: 1-year expiry for assets
- Deny access to hidden files
- Health check endpoint
## Kubernetes Deployment
### Helm Chart Structure
**Chart.yaml** - Chart metadata
**values.yaml** - Default configuration (override for different environments)
**values-lab.yaml** - Home-lab specific values
- Single replicas
- Local storage classes
- Default passwords (change in production)
**values-aws.yaml** - AWS specific values
- Multiple replicas
- EBS storage class
- ALB ingress class
- RDS database URL
**Templates:**
- `namespace.yaml` - Creates dedicated namespace
- `configmap.yaml` - Backend and frontend config
- `secret.yaml` - PostgreSQL credentials
- `postgres.yaml` - PostgreSQL deployment + PVC + service
- `backend.yaml` - Backend deployment + service
- `frontend.yaml` - Frontend deployment + service
- `ingress.yaml` - Ingress for both services
### Deployment Flow
1. Helm reads values file
2. Templates rendered with values
3. Kubernetes resources created in order:
- Namespace
- ConfigMap, Secret
- PVC
- Postgres deployment waits for PVC
- Backend deployment waits for postgres
- Frontend deployment (no deps)
- Services for each
- Ingress routes traffic
### Network Architecture
```
Internet
|
Ingress (nginx/traefik)
|
+-> Frontend Service (80) -> Frontend Pods
|
+-> Backend Service (8000) -> Backend Pods
|
Postgres Service (5432)
|
Postgres Pod
```
### Storage
**PVC for Postgres:**
- ReadWriteOnce access mode
- Survives pod restarts
- Data persists across deployments
**PVC for Backend Media:**
- ReadWriteMany access mode (for multiple replicas)
- Shared media storage across pods
- Migrates to S3 for cloud deployments
## Development Workflow
### Local Testing
```bash
# 1. Modify code
# 2. Test with compose
docker-compose up -d
curl http://localhost:8000/docs
# 3. Modify Helm values
# 4. Test with Helm (dry-run)
helm install dating-app ./helm/dating-app \
-n dating-app --dry-run --debug
# 5. Test with Helm (actual)
helm install dating-app ./helm/dating-app \
-n dating-app --create-namespace
# 6. Verify
kubectl get all -n dating-app
```
### Code Changes
**Backend changes:**
- Edit Python files in app/
- Changes automatically available in dev environment
- Production requires rebuilding Docker image
**Frontend changes:**
- Edit .jsx files
- Changes automatically available in dev environment
- Production requires rebuilding and redeploying
**Database schema changes:**
- Modify app/db.py init_db()
- For Alembic (future): `alembic revision --autogenerate`
- Existing migrations: Update manually or recreate database
## Performance Considerations
### Backend
- Connection pooling limits: Currently 1-20 connections
- Query optimization: Use indexes on foreign keys
- Response caching: Can add for discover endpoint
- Pagination: Not implemented yet, add for large datasets
### Frontend
- Image optimization: Profile pictures should be compressed
- Lazy loading: Add for discover card images
- Code splitting: Can split by route
- Caching: Service workers for offline support
### Database
- Indexes created on common query columns
- JSONB for interests enables efficient queries
- Unique constraints prevent duplicates
- Foreign keys maintain referential integrity
## Testing Strategy
### Unit Tests (Future)
```python
# backend/tests/
# test_auth.py - Auth functions
# test_services.py - Service logic
# test_routers.py - API endpoints
```
### Integration Tests (Future)
```python
# Full workflow testing
# Database interactions
# API contract validation
```
### E2E Tests (Future)
```javascript
# frontend/tests/
# User registration flow
# Profile creation
# Swiping and matching
# Chat functionality
```
### Manual Testing Checklist
- [ ] Registration with new email
- [ ] Login with correct password
- [ ] Create and update profile
- [ ] Upload multiple photos
- [ ] Delete photos
- [ ] View discover profiles
- [ ] Like a user
- [ ] Check matches
- [ ] Send message to match
- [ ] View conversation history
- [ ] Logout
## Security Considerations
### Current Implementation
- ✅ Password hashing with bcrypt
- ✅ JWT with expiration
- ✅ CORS configured
- ✅ Protected endpoints
- ✅ SQL injection prevention (parameterized queries)
### Recommended Additions
- [ ] Rate limiting on auth endpoints
- [ ] HTTPS/TLS enforcement
- [ ] CSRF token for state-changing operations
- [ ] Input validation and sanitization
- [ ] Audit logging
- [ ] API key authentication for service-to-service
- [ ] Secrets management (Vault)
- [ ] Regular security scanning
- [ ] Penetration testing
### Data Protection
- [ ] Encrypt sensitive data in transit (HTTPS)
- [ ] Encrypt sensitive data at rest
- [ ] Implement data retention policies
- [ ] GDPR compliance (right to delete, data export)
- [ ] Regular backups with encryption
- [ ] Secure backup storage
## Common Issues & Solutions
### Issue: Photo uploads fail
**Cause:** Media directory not writable
**Solution:** Check MEDIA_DIR permissions, ensure PVC mounted
### Issue: Matches not showing
**Cause:** Mutual like check query fails
**Solution:** Verify both users liked each other, check database
### Issue: Slow profile discovery
**Cause:** N+1 query problem
**Solution:** Add query optimization, batch load photos
### Issue: Connection pool exhausted
**Cause:** Too many concurrent requests
**Solution:** Increase pool size, add connection timeout
## Future Enhancements
1. **WebSocket Chat**
- Real-time messages without polling
- Typing indicators
- Read receipts
2. **Image Optimization**
- Automatic compression
- Multiple sizes for responsive design
- CDN distribution
3. **Recommendation Engine**
- Machine learning for match suggestions
- Interest-based filtering
- Location-based matching
4. **Advanced Features**
- Video calls
- Story features
- Search and filtering
- Blocking/reporting
- Verification badges
5. **Infrastructure**
- Load balancing improvements
- Caching layer (Redis)
- Message queue (RabbitMQ) for async tasks
- Monitoring and alerting
- CI/CD pipeline
- Database read replicas

## 🌐 AWS Migration Guide
### Switch from Local Storage to S3
1. Update backend environment:
```env
STORAGE_TYPE=s3
AWS_BUCKET_NAME=your-bucket
AWS_REGION=us-east-1
```
2. Modify [backend/app/services/photo_service.py](backend/app/services/photo_service.py) to use boto3
3. Update media serving to redirect to S3 presigned URLs
### Switch from Local PostgreSQL to RDS
1. Create RDS instance in AWS
2. Update values in Helm chart:
```yaml
postgres:
enabled: false # Disable embedded Postgres
backend:
environment:
DATABASE_URL: postgresql://user:pass@rds-endpoint.amazonaws.com:5432/db
```
3. Deploy with updated values
### Load Balancer & Auto-scaling
Helm chart supports AWS Application Load Balancer (ALB):
```yaml
ingress:
className: aws-alb
annotations:
alb.ingress.kubernetes.io/scheme: internet-facing
```
Set replicas in values for auto-scaling base:
```yaml
backend:
replicas: 3
frontend:
replicas: 3
```
## 🧪 Testing
### API Testing with curl
```bash
# Register
curl -X POST http://localhost:8000/auth/register \
-H "Content-Type: application/json" \
-d '{
"email": "user@example.com",
"password": "password123",
"display_name": "John Doe"
}'
# Login
curl -X POST http://localhost:8000/auth/login \
-H "Content-Type: application/json" \
-d '{
"email": "user@example.com",
"password": "password123"
}'
# Update profile (use token from login response)
curl -X POST http://localhost:8000/profiles/ \
-H "Authorization: Bearer YOUR_TOKEN" \
-H "Content-Type: application/json" \
-d '{
"display_name": "John Doe",
"age": 28,
"gender": "male",
"location": "San Francisco",
"bio": "Looking for someone...",
"interests": ["hiking", "travel"]
}'
```

# Helm Chart README
## Dating App Helm Chart
This Helm chart deploys the MVP dating application to Kubernetes with all necessary components.
### Prerequisites
- Kubernetes 1.19+
- Helm 3.0+
- Nginx Ingress Controller (for ingress)
- Storage provisioner (for PVC)
### Installation
#### Basic Installation (Development)
```bash
# Install with default values
helm install dating-app ./helm/dating-app -n dating-app --create-namespace
```
#### Production Installation with Custom Values
```bash
# Create custom values file
cp helm/dating-app/values.yaml my-values.yaml
# Edit my-values.yaml with your configuration
# Then install
helm install dating-app ./helm/dating-app -n dating-app --create-namespace -f my-values.yaml
```
### Configuration
Edit `values.yaml` to customize:
#### Ingress Hosts
```yaml
backend:
ingress:
host: api.yourdomain.com
frontend:
ingress:
host: app.yourdomain.com
```
#### Database
```yaml
postgres:
credentials:
username: your_user
password: your_password
database: your_db
```
#### Backend Environment
```yaml
backend:
environment:
JWT_SECRET: your-secret-key
CORS_ORIGINS: "https://app.yourdomain.com"
```
#### Frontend API URL
```yaml
frontend:
environment:
VITE_API_URL: "https://api.yourdomain.com"
```
#### Storage Classes
For cloud deployments (AWS, GCP, etc.), specify storage class:
```yaml
backend:
persistence:
storageClass: ebs-sc # AWS EBS
size: 10Gi
postgres:
persistence:
storageClass: ebs-sc
size: 20Gi
```
#### Replicas and Resources
```yaml
backend:
replicas: 3
resources:
requests:
memory: "512Mi"
cpu: "200m"
limits:
memory: "1Gi"
cpu: "500m"
frontend:
replicas: 2
resources:
requests:
memory: "256Mi"
cpu: "100m"
limits:
memory: "512Mi"
cpu: "200m"
```
### Upgrading
```bash
helm upgrade dating-app ./helm/dating-app -f my-values.yaml
```
### Uninstalling
```bash
helm uninstall dating-app -n dating-app
```
### AWS Migration
To deploy to AWS:
1. **RDS for PostgreSQL**: Disable postgres in chart
```yaml
postgres:
enabled: false
```
2. **Update database URL** to RDS endpoint
```yaml
backend:
environment:
DATABASE_URL: "postgresql://user:password@your-rds-endpoint:5432/dating_app"
```
3. **S3 for Media Storage**: Update backend environment
```yaml
backend:
environment:
MEDIA_STORAGE: s3
S3_BUCKET: your-bucket
AWS_REGION: us-east-1
```
4. **Use AWS Load Balancer Controller** for ingress
```yaml
ingress:
className: aws-alb
annotations:
alb.ingress.kubernetes.io/scheme: internet-facing
```
5. **Use EBS for persistent storage**
```yaml
backend:
persistence:
storageClass: ebs-sc
```
### Troubleshooting
Check pod status:
```bash
kubectl get pods -n dating-app
kubectl logs -n dating-app <pod-name>
```
Check services:
```bash
kubectl get svc -n dating-app
```
Check ingress:
```bash
kubectl get ingress -n dating-app
```
Port forward for debugging:
```bash
kubectl port-forward -n dating-app svc/backend 8000:8000
kubectl port-forward -n dating-app svc/frontend 3000:80
```
### Database Initialization
The backend automatically initializes tables on startup. To verify:
```bash
kubectl exec -it -n dating-app <postgres-pod> -- psql -U dating_user -d dating_app -c "\dt"
```
### Notes
- This chart is designed to be portable between on-premises and cloud deployments
- Modify `values.yaml` for your specific infrastructure
- For production, use external secrets management (HashiCorp Vault, AWS Secrets Manager, etc.)
- Enable TLS/SSL with cert-manager for production ingress
- Configure proper backup strategies for PostgreSQL PVC

-- Password hashes used in sample data:
-- - Hash: $2b$12$LQv3c1yqBWVHxkd0LHAkCOYz6TtxMQJqhN8/LewY5YmMxSUmGEJiq
-- - Password: 'password123'
--
-- To generate your own bcrypt hash, use Python:
-- from passlib.context import CryptContext
-- pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")
-- hash = pwd_context.hash("your_password_here")
--
-- IMPORTANT BEFORE PRODUCTION:
-- 1. Change all password hashes to actual user passwords
-- 2. Update email addresses to real users
-- 3. Consider using proper user import/registration instead of direct inserts
-- 4. Remove sample data if not needed
