⚠️ Important Notes

Customer ID Coordination

The seed data uses fixed customer IDs defined in SeedDataConstants.java. These MUST match the user IDs created by the Authentication Service seeder:

CUSTOMER_1_ID = "customer1-uuid-0000-0000-000000000001"
CUSTOMER_2_ID = "customer2-uuid-0000-0000-000000000002"
CUSTOMER_3_ID = "customer3-uuid-0000-0000-000000000003"

Action Required: Update these constants to match actual Auth Service UUIDs when available.

Production Considerations

  1. Change spring.profiles.active to prod
  2. Set DB_MODE to validate (not update)
  3. Configure cloud storage for photos
  4. Set up CDN for image delivery
  5. Enable connection pooling
  6. Configure proper backup strategy
  7. Set up monitoring and alerting

📞 API Gateway Integration

The service is configured to work with the API Gateway:

Gateway Route: /api/v1/vehicles/* → http://vehicle-service:8082

Headers Required:

  • Authorization: Bearer <jwt-token>
  • X-User-Subject: <customer-id> (set by gateway)

Authentication: Gateway validates JWT and forwards user ID
