Cloud Cost Chefs Azure Auto-Tagging Function: Automate Your Tags Like a Pro—No Effort Required

🔍 What It Does

• Listens for ResourceWriteSuccess events from Event Grid
• Extracts creator info straight from their identity claims
• Auto-applies tags like: CreatedBy, CreatedTime, IP Address (optional, but nerdy cool).
• Works via Az PowerShell with a REST API fallback (just in case Az goes grumpy)

⚙️ Requirements Checklist

• ✅ An Azure Function App (PowerShell 7 + Consumption Plan)
• ✅ A System-assigned Managed Identity with at least Tag Contributor role
• ✅ An Event Grid System Topic + Subscription per Azure region or subscription

📌 Talk Nerdy Tip:

This script turns “resource chaos” into “clean tagging hygiene.” No more budget black holes or ghost resources. Want the script? I’ll serve it hot and ready with YAML sprinkles.
