Usage

Scan CI Pipeline

name: build
on:
  push:
    branches:
      - master
  pull_request:
jobs:
  build:
    name: Build
    runs-on: ubuntu-20.04
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Build an image from Dockerfile
        run: |
          docker build -t docker.io/my-organization/my-app:${{ github.sha }} .
      - name: Run Trivy vulnerability scanner
        uses: aquasecurity/trivy-action@master
        with:
          image-ref: 'docker.io/my-organization/my-app:${{ github.sha }}'
          format: 'table'
          exit-code: '1'
          ignore-unfixed: true
          vuln-type: 'os,library'
          severity: 'CRITICAL,HIGH'

Scan CI Pipeline (w/ Trivy Config)

name: build
on:
  push:
    branches:
    - master
  pull_request:
jobs:
  build:
    name: Build
    runs-on: ubuntu-20.04
    steps:
    - name: Checkout code
      uses: actions/checkout@v2

    - name: Run Trivy vulnerability scanner in repo mode
      uses: aquasecurity/trivy-action@add-support-for-trivy-config
      with:
        scan-type: 'fs'
        ignore-unfixed: true
        trivy-config: ./trivy.yaml

In this case trivy.yaml is a YAML configuration that is checked in as part of the repo. Detailed information is available on the Trivy website but an example is as follows:

format: json
exit-code: 1
severity: CRITICAL

It is possible to define all options in the trivy.yaml file. Specifying individual options via the action are left for backward compatibility purposes.

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: 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 Trivy vulnerability scanner
        uses: aquasecurity/trivy-action@master
        with:
          image-ref: 'docker.io/my-organization/my-app:${{ github.sha }}'
          format: 'sarif'
          output: 'trivy-results.sarif'

      - name: Upload Trivy scan results to GitHub Security tab
        uses: github/codeql-action/upload-sarif@v2
        with:
          sarif_file: 'trivy-results.sarif'

You can find a more in-depth example here: https://github.com/aquasecurity/trivy-sarif-demo/blob/master/.github/workflows/scan.yml

If you would like to upload SARIF results to GitHub Code scanning even upon a non zero exit code from Trivy Scan, you can add the following to your upload step:

  pull_request:
jobs:
  build:
    name: Build
    runs-on: ubuntu-18.04
    steps:
      - 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 Trivy vulnerability scanner
        uses: aquasecurity/trivy-action@master
        with:

Using Trivy to scan your private registry

It's also possible to scan your private registry with Trivy's built-in image scan. All you have to do is set ENV vars.

Docker Hub registry

Docker Hub needs TRIVY_USERNAME and TRIVY_PASSWORD. You don't need to set ENV vars when downloading from a public repository.

name: build
on:
  push:
    branches:
      - master
  pull_request:
jobs:
  build:
    name: Build
    runs-on: ubuntu-18.04
