Using Trivy with GitHub Code Scanning

If you have GitHub code scanning available you can use Trivy as a scanning tool as follows:

name: build
on:
  push:
    branches:
      - master
  pull_request:
jobs:
  build:
    name: Build
    runs-on: ubuntu-18.04
    steps:
      - name: Setup Go
        uses: actions/setup-go@v1
        with:
          go-version: 1.14
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Build an image from Dockerfile
        run: |
          docker build -t docker.io/my-organization/my-app:${{ github.sha }} .
      - name: Run vulnerability scanner
        uses: aquasecurity/trivy-action@0.0.8
        with:
          image-ref: 'docker.io/my-organization/my-app:${{ github.sha }}'
          format: 'template'
          template: '@/contrib/sarif.tpl'
          output: 'trivy-results.sarif'
      - name: Upload Trivy scan results to Security tab
        uses: github/codeql-action/upload-sarif@v1
        with:
          sarif_file: 'trivy-results.sarif'
