Gh Actions Validator

Overview

Validate and harden GitHub Actions workflows that deploy to Google Cloud (especially Vertex AI) using Workload Identity Federation (OIDC) instead of long-lived service account keys. Use this to audit existing workflows, propose a secure replacement, and add CI checks that prevent common credential and permission mistakes.

Prerequisites

Before using this skill, ensure:

• GitHub repository with Actions enabled
• Google Cloud project with billing enabled
• gcloud CLI authenticated with admin permissions
• Understanding of Workload Identity Federation concepts
• GitHub repository secrets configured
• Appropriate IAM roles for CI/CD automation

Instructions

1. Audit Existing Workflows: Scan .github/workflows/ for security issues
2. Validate WIF Usage: Ensure no JSON service account keys are used
3. Check OIDC Permissions: Verify id-token: write is present
4. Review IAM Roles: Confirm least privilege (no owner/editor roles)
5. Add Security Scans: Include secret detection and vulnerability scanning
6. Validate Deployments: Add post-deployment health checks
7. Configure Monitoring: Set up alerts for deployment failures
8. Document WIF Setup: Provide one-time WIF configuration commands

Output

  - uses: actions/checkout@v4
  - name: Authenticate to GCP (WIF)
  - name: Deploy to Vertex AI
        --project=${{ secrets.GCP_PROJECT_ID }} \
        --region=us-central1
  - name: Validate Deployment
