GCP Resource Inventory Scanner & Architecture Diagram Generator

A Python CLI tool that inventories all your GCP resources and generates beautiful draw.io architecture diagrams.

Features

• 🔍 Inventory Scanning: Scans Compute Engine, Cloud SQL, Cloud Functions, GKE, Cloud Storage, Cloud Run, Firestore, Pub/Sub, and more
• 📊 CSV Export: Export complete inventory to CSV for further analysis
• 🏗️ Architecture Diagrams: Auto-generate draw.io .drawio files with logical service connections
• ☁️ Multi-Project Support: Scan multiple GCP projects in one go
• 🔐 Service Account Auth: Use gcloud default credentials or specify service account key

Installation

pip install gcp-radar

Or from source:

git clone https://github.com/yourname/gcp-radar.git
cd gcp-radar
pip install -e .

Quick Start

1. Inventory Your GCP Resources

# Scan default project
gcp-radar inventory --export inventory.csv

# Scan specific project
gcp-radar inventory --project my-project --export inventory.csv

# Export to specific region
gcp-radar inventory --region us-central1 --export inventory.csv

2. Generate Architecture Diagram

gcp-radar diagram --input inventory.csv --output architecture.drawio

# Then open architecture.drawio in app.diagrams.net or the desktop app

3. One-Shot: Scan + Diagram

gcp-radar run --project my-project \
  --output-csv inventory.csv \
  --output-diagram architecture.drawio
