Absolutely, Pavan! Let’s do a full end-to-end guide for scanning Docker containers and JavaScript (Node.js) code using Snyk in GitHub Actions CI/CD, including account setup, scanning, vulnerabilities, and alerts. I’ll break it step by step so you can implement it directly.

Common Vulnerabilities to Look For

1. Node.js / JS Code

   • Outdated dependencies (npm packages)

   • Known CVEs in libraries like express, lodash, axios

   • Misconfigurations in .env or secrets

2. Docker Images

   • OS package vulnerabilities (Debian, Alpine, Ubuntu)

   • Outdated base images

   • Privilege escalation risks

   • Exposed ports, secrets inside image

---

End-to-End Snyk Setup and CI/CD Integration

---

1️⃣ Create a Snyk Account

1. Go to https://snyk.io and sign up:

   • Use GitHub, Google, or email.

2. Verify your email.

3. After login:

   • Navigate to API token → You’ll use this in GitHub secrets.

---

2️⃣ Add Snyk Token to GitHub

1. Go to your GitHub repo → Settings → Secrets and variables → Actions → New repository secret

2. Add:

   • Name: SNYK_TOKEN

   • Value: Your Snyk API token

3. (Optional) If scanning Docker images from Docker Hub, also add:

   • DOCKERHUB_USERNAME and DOCKERHUB_PASSWORD as secrets.

---

3️⃣ Install Snyk CLI Locally (Optional)

npm install -g snyk
snyk auth

• Authenticates your CLI with the token.

---

4️⃣ GitHub Actions Workflow

Create a workflow file: .github/workflows/snyk-scan.yml

name: Snyk Scan CI/CD

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

jobs:
  snyk-scan:
    runs-on: ubuntu-latest
    steps:
      # 1. Checkout the repo
      - name: Checkout Code
        uses: actions/checkout@v3

      # 2. Set up Node.js (for JS scanning)
      - name: Setup Node.js
        uses: actions/setup-node@v3
        with:
          node-version: '18'

      # 3. Scan Node.js dependencies (package.json)
      - name: Snyk Node.js Dependency Scan
        uses: snyk/actions/node@master
        env:
          SNYK_TOKEN: ${{ secrets.SNYK_TOKEN }}
        with:
          args: --file=package.json

      # 4. Build Docker image
      - name: Build Docker Image
        run: |
          docker build -t myapp:latest .

      # 5. Scan Docker container
      - name: Snyk Container Scan
        uses: snyk/actions/docker@master
        env:
          SNYK_TOKEN: ${{ secrets.SNYK_TOKEN }}
        with:
          image: myapp:latest
          args: --file=Dockerfile

✅ This workflow does both Node.js dependency scanning and Docker image scanning in CI/CD.

---

5️⃣ Checking Vulnerabilities

• After a push or PR, check GitHub Actions logs for:

  • Vulnerabilities in dependencies (Node.js packages)

  • OS/package vulnerabilities in Docker images

• Snyk categorizes them by severity:

  • Critical

  • High

  • Medium

  • Low

• It also suggests fixes automatically:

  • npm audit fix or update Docker base image

---

6️⃣ Setting Alerts in GitHub Actions

To fail the CI/CD pipeline on vulnerabilities:

# Add to the scan steps
args: --file=package.json --fail-on=high

• --fail-on=high → Pipeline will fail if high/critical vulnerabilities are found

• Alternative: --json to export report for dashboards

---

7️⃣ Common Vulnerabilities to Look For

1. Node.js / JS Code

   • Outdated dependencies (npm packages)

   • Known CVEs in libraries like express, lodash, axios

   • Misconfigurations in .env or secrets

2. Docker Images

   • OS package vulnerabilities (Debian, Alpine, Ubuntu)

   • Outdated base images

   • Privilege escalation risks

   • Exposed ports, secrets inside image

---

8️⃣ Best Practices

• Use official Docker base images (Alpine, Node LTS)

• Scan both code and container on every push or PR

• Fail pipeline for high severity vulnerabilities

• Periodically update dependencies and base images

• Use Snyk dashboards for historical tracking

---

9️⃣ Optional: Notifications

• Use GitHub Actions if: failure() to send Slack / email alerts

• Example:

- name: Notify Slack on Failure
  if: failure()
  uses: slackapi/[email protected]
  with:
    channel-id: 'C123456'
    slack-message: '🚨 Snyk scan failed! Check pipeline logs.'
    slack-token: ${{ secrets.SLACK_TOKEN }}

---

✅ Summary

Step	What It Does
Snyk Account & Token	Authenticates scans
GitHub Secrets	Keeps token safe
Node.js Dependency Scan	Checks JS packages
Docker Container Scan	Checks OS & app layer vulnerabilities
Fail-on-High	Stops pipeline on serious issues
Notifications	Alerts team of vulnerabilities

---

If you want, I can create a single, super-simple CI/CD workflow that automatically scans Node.js + Docker + fails on high severity + alerts Slack. It’ll be plug-and-play for your repo.

Do you want me to do that?
