Devolv Drift — CI/CD-First IAM Policy Drift Detection

devolv drift is a CI/CD-first tool that automatically detects IAM policy drift between your local files and deployed AWS IAM policies. It is designed primarily for automated pipelines, with local CLI use as a secondary option.

---

🚀 Why Devolv Drift in CI/CD?

✅ Automate IAM drift detection on every PR, push, or merge
✅ Auto-create PRs or issues to resolve drift
✅ No manual AWS console checks
✅ Secure OIDC-based AWS access — no long-term credentials

👉 CI/CD is the primary use case — local CLI use is optional for manual checks.

---

📦 How to Get Started

1️⃣ Install Devolv (for local CLI use)

pip install devolv

✅ Required if you want to run devolv drift manually outside CI/CD.

⚠ Note: In CI/CD, installation is typically handled by your workflow or container image — you don't need to install it manually.

---

2️⃣ Set Up AWS OIDC Role for GitHub Actions

Download our onboarding script:
https://github.com/devolvdev/devolv-actions/blob/main/devolv_oidc_onboard.py

Download via terminal:

curl -O https://raw.githubusercontent.com/devolvdev/devolv-actions/main/devolv_oidc_onboard.py

Run in AWS CloudShell or any AWS CLI-authenticated machine:

python devolv_oidc_onboard.py --github-org YourOrgName

✅ This will:

• Set up the OIDC provider (if missing)
• Create an IAM role trusted for your GitHub org
• Attach IAM policy permissions needed by Devolv Drift
• Output the role ARN + a GitHub Actions block

---

3️⃣ Add GitHub Actions Workflow

Create a file at:

.github/workflows/devolv-drift.yml

Example contents:

permissions:
  id-token: write
  contents: write
  pull-requests: write
  issues: write

jobs:
  drift-check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - uses: aws-actions/configure-aws-credentials@v4
        with:
          role-to-assume: arn:aws:iam::<account_id>:role/YourOrg-DevolvRole
          aws-region: us-east-1

      - name: Run Devolv Drift
        uses: devolvdev/devolv-actions@v2
        with:
          tool: drift
          policy-name: DevolvTestPolicy
          path: ./test-devolv-policy.json
          approvers: ""                  # Empty by default; pass comma-separated list if needed
          github-token: ${{ secrets.GITHUB_TOKEN }}
          approval-anyway: false        # false by default; 

✅ ⚠ Mandatory repository setting:
In your GitHub repository settings under Actions → General → actions, ensure you enable:

☑ Allow GitHub Actions to create and approve pull requests

This is required for Devolv Drift to auto-create PRs.

---

📝 What Devolv Drift Does in CI/CD

✅ Checks your local IAM policy files against live AWS policies
✅ Shows a rich, colorized diff of detected drift in workflow logs
✅ Automatically opens PRs to sync your code or propose AWS updates
✅ Optionally opens issues to track drift findings

---

✅ OIDC AWS role set up using devolv_oidc_onboard.py
✅ Workflow file includes correct permissions: block
✅ Repository setting enabled to allow Actions to create/approve PRs
