GCP Stack Baseline
Summary (3–6 bullets)
- Defines the canonical Google Cloud baseline for production operations.
- Establishes service naming, IAM/WIF auth model, and runtime identity boundaries.
- Captures minimum requirements for Cloud Run, BigQuery, Firestore, GCS, and Secret Manager.
- Provides a single operator checklist before release/cutover.
When to use this (3–6 bullets)
- Before provisioning a new environment.
- Before release readiness and production deploy certification.
- During incident triage when infra/auth scope is unclear.
- When validating that docs and runtime posture match.
What you’ll walk away with (2–5 bullets)
- A canonical naming map for active Cloud Run services.
- A minimum GCP control checklist that must be true before go-live.
- Direct links to runbooks for Firestore, Secret Manager, and GCS baselines.
Canonical service naming
Use this map as the source of truth:- System of Record API:
payroll-backend-prod - Config Plane API:
payroll-pipeline-cbs-api - Legacy/compat reference (do not use for new deploy docs):
payroll-pipeline-cbs
Required APIs
Auth and IAM baseline
- GitHub Actions authentication uses Workload Identity Federation (WIF).
- CI deploy identity:
sa-github-deployer@payroll-bi-gauntlet.iam.gserviceaccount.com - Runtime identity:
sa-worker@payroll-bi-gauntlet.iam.gserviceaccount.com - Deployer must have, at minimum:
roles/run.adminroles/iam.serviceAccountUser(on runtime SA)roles/cloudbuild.builds.editorroles/storage.adminroles/artifactregistry.writerroles/serviceusage.serviceUsageConsumer
Cloud Run baseline
- Region:
us-central1 - Deploy via GitHub Actions WIF workflows.
- Required runtime env vars:
GCP_PROJECT_ID=payroll-bi-gauntletSTAGE=prodGIT_COMMIT_SHA=<sha>ONBOARDING_STORAGE_BUCKET=payroll-bi-gauntlet-onboarding-storage
- Required secret wiring:
JWT_SECRET_KEY=jwt-secret:latest
Data and state baseline
- BigQuery: contracts and schema expectations are defined in BQ_CONTRACT.
- Firestore: required for exactly-once coordination/mutex checks on Phase 8S+ paths.
- GCS: onboarding and staging object paths must use tenant/batch scoped prefixes.
- Secret Manager: credential material must stay in Secret Manager (tables store refs only).
Release-readiness minimum checklist
- APIs enabled for runtime and CI paths
- WIF provider and IAM bindings verified
- Both Cloud Run services healthy and serving expected revision
- Firestore preflight passes for both services
- Secret Manager access verified for runtime SA
- GCS bucket IAM + lifecycle baseline validated
- BigQuery contracts and partition-filter rules validated
