# Infrastructure Status Report

**Date**: 2025-09-29
**Status**: ✅ **ALL SYSTEMS OPERATIONAL**
**Last Updated**: 2025-09-29 20:15 UTC

## Executive Summary

All Docker Compose services are running and healthy. All health check issues have been resolved. The infrastructure is fully operational for both:

- **Production-like deployment** (Docker Compose with authentication)
- **Local development** (Standalone services with `DISABLE_AUTH=true`)

### Recent Fixes Applied

✅ **Traefik Health Checks**: Fixed health check endpoint from `/health` to `/healthz` - no more 500 errors
✅ **Development Mode**: Fixed environment variable parsing for `DISABLE_AUTH`
✅ **Documentation**: Created comprehensive guides for development and deployment

See [FIXES_APPLIED.md](FIXES_APPLIED.md) for detailed information.

## Health Check Configuration

### Infrastructure Services

All infrastructure services have health checks configured:

```yaml
# PostgreSQL
healthcheck:
  test: ["CMD-SHELL", "pg_isready -U postgres"]
  interval: 30s
  timeout: 10s
  retries: 3

# Redis
healthcheck:
  test: ["CMD-SHELL", "redis-cli ping | grep PONG"]
  interval: 30s
  timeout: 10s
  retries: 3

# MinIO
healthcheck:
  test: ["CMD", "mc", "--version"]
  interval: 30s
  timeout: 20s
  retries: 3

# NATS
healthcheck:
  test: ["CMD", "wget", "--no-verbose", "--tries=1", "--spider", "http://localhost:8222/healthz"]
  interval: 30s
  timeout: 10s
  retries: 3
```

### Application Services

All application services have health checks in their Dockerfiles:

```dockerfile
HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 \
    CMD curl -f http://localhost:8000/healthz || exit 1
```

The `/healthz` endpoint is a public endpoint that doesn't require authentication.

## Configuration Fixes Applied

### 1. Authentication Middleware Enhancement

**File**: `libs/config/settings.py`

Added proper environment variable aliases for development mode:

```python
# Development settings
dev_mode: bool = Field(
    default=False,
    description="Enable development mode (disables auth)",
    validation_alias="DEV_MODE"
)
disable_auth: bool = Field(
    default=False,
    description="Disable authentication middleware",
    validation_alias="DISABLE_AUTH"
)
```

### 2. Middleware Configuration

**File**: `libs/security/middleware.py`

The middleware correctly handles development mode:

```python
async def dispatch(self, request: Request, call_next: Callable[..., Any]) -> Any:
    # Check if authentication is disabled (development mode)
    if self.disable_auth:
        # Set development state
        request.state.user = "dev-user"
        request.state.email = "dev@example.com"
        request.state.roles = ["developers"]
        request.state.auth_token = "dev-token"
        logger.info("Development mode: authentication disabled", path=request.url.path)
        return await call_next(request)
    # ... rest of authentication logic
```

### 3. App Factory Integration

**File**: `libs/app_factory.py`

The app factory correctly passes the `disable_auth` setting to middleware:

```python
# Add middleware
app.add_middleware(
    TrustedProxyMiddleware,
    internal_cidrs=settings.internal_cidrs,
    disable_auth=getattr(settings, "disable_auth", False),
)
```

## Running Services

### Docker Compose (Production-like)

All services run with full authentication:

```bash
# Start all services
cd infra/compose
docker-compose -f docker-compose.local.yml up -d

# Check status
docker-compose -f docker-compose.local.yml ps

# View logs
docker-compose -f docker-compose.local.yml logs -f SERVICE_NAME
```

### Local Development (Standalone)

Services can run locally with authentication disabled:

```bash
# Run with authentication disabled
DISABLE_AUTH=true make dev-service SERVICE=svc_ingestion

# Or directly with uvicorn
DISABLE_AUTH=true cd apps/svc_ingestion && uvicorn main:app --reload --host 0.0.0.0 --port 8000
```

## Testing

### Health Check Verification

```bash
# Test public health endpoint
curl http://localhost:8000/healthz

# Expected response:
# {"status":"healthy","service":"svc-ingestion","version":"1.0.0"}
```

### Development Mode Verification

When running with `DISABLE_AUTH=true`, logs show:

```json
{
  "path": "/healthz",
  "event": "Development mode: authentication disabled",
  "logger": "libs.security.middleware",
  "level": "info",
  "service": "svc-ingestion",
  "timestamp": 1759175839.638357
}
```

### Production Mode Testing

Without `DISABLE_AUTH`, requests require authentication headers:

```bash
curl -X POST http://localhost:8000/upload \
  -H "X-Authenticated-User: dev-user" \
  -H "X-Authenticated-Email: dev@example.com" \
  -H "Authorization: Bearer dev-token-12345" \
  -F "file=@document.pdf"
```

## Network Configuration

### Docker Networks

- **ai-tax-agent-frontend**: Public-facing services (Traefik, UI)
- **ai-tax-agent-backend**: Internal services (databases, message brokers, application services)

### Port Mappings

| Service    | Internal Port    | External Port    | Access   |
| ---------- | ---------------- | ---------------- | -------- |
| Traefik    | 80, 443, 8080    | 80, 443, 8080    | Public   |
| PostgreSQL | 5432             | 5432             | Internal |
| Redis      | 6379             | 6379             | Internal |
| MinIO      | 9092-9093        | 9092-9093        | Internal |
| Neo4j      | 7474, 7687       | 7474, 7687       | Internal |
| NATS       | 4222, 6222, 8222 | 4222, 6222, 8222 | Internal |
| Grafana    | 3000             | 3000             | Public   |
| Prometheus | 9090             | 9090             | Internal |
| Unleash    | 4242             | 4242             | Internal |

## Next Steps

1. ✅ **Infrastructure**: All services operational
2. ✅ **Health Checks**: All passing
3. ✅ **Development Mode**: Working correctly
4. ✅ **Authentication**: Properly configured for both modes
5. 📝 **Documentation**: Created comprehensive guides

### For Developers

- See [DEVELOPMENT.md](DEVELOPMENT.md) for local development setup
- Use `DISABLE_AUTH=true` for local testing with Postman
- All services support hot reload with `--reload` flag

### For Operations

- Monitor service health: `docker-compose ps`
- View logs: `docker-compose logs -f SERVICE_NAME`
- Restart services: `docker-compose restart SERVICE_NAME`
- Check metrics: http://localhost:9090 (Prometheus)
- View dashboards: http://localhost:3000 (Grafana)

## Conclusion

✅ **All systems are operational and healthy**
✅ **Development mode working correctly**
✅ **Production mode working correctly**
✅ **Documentation complete**

The infrastructure is ready for both development and production-like testing.
