Demo Inventory Seeding Script for Inventory Service
|
|
Creates realistic Spanish ingredients for demo template tenants
|
|
|
|
This script runs as a Kubernetes init job inside the inventory-service container.
|
|
It populates the template tenants with a comprehensive catalog of ingredients.
|
|
|
|
Usage:
|
|
python /app/scripts/demo/seed_demo_inventory.py
|
|
|
|
Environment Variables Required:
|
|
INVENTORY_DATABASE_URL - PostgreSQL connection string for inventory database
|
|
DEMO_MODE - Set to 'production' for production seeding
|
|
LOG_LEVEL - Logging level (default: INFO)
