Secrets & Env Manager

Secure secrets handling and environment variable validation in CI/CD.

Environment Variable Validation

validate-env:
  runs-on: ubuntu-latest
  steps:
    - uses: actions/checkout@v4

    - name: Validate required environment variables
      run: |
        REQUIRED_VARS=(
          "DATABASE_URL"
          "API_KEY"
          "AWS_REGION"
          "STRIPE_SECRET_KEY"
        )

        MISSING=()
        for var in "${REQUIRED_VARS[@]}"; do
          if [ -z "${!var}" ]; then
            MISSING+=("$var")
          fi
        done

        if [ ${#MISSING[@]} -ne 0 ]; then
          echo "❌ Missing required environment variables:"
          printf '%s\n' "${MISSING[@]}"
          exit 1
        fi

        echo "✅ All required environment variables are set"
      env:
        DATABASE_URL: ${{ secrets.DATABASE_URL }}
        API_KEY: ${{ secrets.API_KEY }}
        AWS_REGION: ${{ secrets.AWS_REGION }}
        STRIPE_SECRET_KEY: ${{ secrets.STRIPE_SECRET_KEY }}

Secret Masking

- name: Mask sensitive values
  run: |
    # Automatically masked in GitHub Actions
    echo "::add-mask::${{ secrets.API_KEY }}"
    echo "::add-mask::${{ secrets.DATABASE_PASSWORD }}"

    # Safe to use in commands
    curl -H "Authorization: Bearer ${{ secrets.API_KEY }}" https://api.example.com

Leak Prevention

- name: Check for leaked secrets
  uses: trufflesecurity/trufflehog@main
  with:
    path: ./
    base: ${{ github.event.repository.default_branch }}
    head: HEAD

- name: Detect hardcoded secrets
  uses: reviewdog/action-detect-secrets@master
  with:
    github_token: ${{ secrets.GITHUB_TOKEN }}
    reporter: github-pr-review

Environment-specific Secrets

deploy:
  runs-on: ubuntu-latest
  environment:
    name: ${{ github.event.inputs.environment }}
  steps:
    - name: Deploy
      run: |
        # Environment-specific secrets are automatically scoped
        echo "Deploying to ${{ github.event.inputs.environment }}"
      env:
        DATABASE_URL: ${{ secrets.DATABASE_URL }}
        API_KEY: ${{ secrets.API_KEY }}
