Google Cloud Inventory Automation

A GitHub Actions pipeline that automatically generates and versions a Google Cloud inventory using read-only access and keyless OIDC authentication.

Cloud
Problem
A manually maintained cloud inventory quickly becomes stale, while long-lived service-account keys increase operational risk.
Solution
The workflow uses Workload Identity Federation to impersonate a read-only service account, queries Cloud Asset Inventory and Service Usage API, and commits outputs only when they change.
Outcome
A transparent, versioned inventory stored in the repository and updated without paid GCP services or persistent JSON credentials.

Federated identity

GitHub obtains a temporary identity through OIDC and can impersonate only the service account authorized for that repository. The required permissions are read-oriented and remain revocable from Google Cloud.

Inventory as code

The Python script produces outputs tracked in Git; the workflow compares results and creates a commit only when changes are present, preserving a history of observed resources.
