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:

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
        if: always()
        with:
          sarif_file: 'trivy-results.sarif'

Using Trivy to scan your Git repo

It's also possible to scan your git repos with Trivy's built-in repo scan. This can be handy if you want to run Trivy as a build time check on each PR that gets opened in your repo. This helps you identify potential vulnerablites that might get introduced with each PR.

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: Run Trivy vulnerability scanner in repo mode
        uses: aquasecurity/trivy-action@master
        with:
          scan-type: 'fs'
          ignore-unfixed: true
          format: 'sarif'
          output: 'trivy-results.sarif'
          severity: 'CRITICAL'

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

Using Trivy to scan your rootfs directories

It's also possible to scan your rootfs directories with Trivy's built-in rootfs scan. This can be handy if you want to run Trivy as a build time check on each PR that gets opened in your repo. This helps you identify potential vulnerablites that might get introduced with each PR.

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:

      - name: Run Trivy vulnerability scanner with rootfs command
        uses: aquasecurity/trivy-action@master
        with:
          scan-type: 'rootfs'
          scan-ref: 'rootfs-example-binary'
          ignore-unfixed: true
          format: 'sarif'
          output: 'trivy-results.sarif'

        with:
          sarif_file: 'trivy-results.sarif'

Using Trivy to scan Infrastucture as Code

It's also possible to scan your IaC repos with Trivy's built-in repo scan. This can be handy if you want to run Trivy as a build time check on each PR that gets opened in your repo. This helps you identify potential vulnerablites that might get introduced with each PR.

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

name: build
on:
  push:
    branches:
      - master

        with:
          sarif_file: 'trivy-results.sarif'

Using Trivy to generate SBOM

It's possible for Trivy to generate an SBOM of your dependencies and submit them to a consumer like GitHub Dependency Snapshot.

The sending of SBOM to GitHub feature is only available if you currently have GitHub Dependency Snapshot available to you in your repo.

In order to send results to the GitHub Dependency Snapshot, you will need to create a GitHub PAT

  push:
    branches:
    - master
  pull_request:
jobs:
  build:
    name: Checks
    runs-on: ubuntu-20.04

        with:
          scan-type: 'fs'
          format: 'github'
          output: 'dependency-results.sbom.json'
          image-ref: '.'
          github-pat: '<github_pat_token>'

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
    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - 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'
        env:
          TRIVY_USERNAME: Username
          TRIVY_PASSWORD: Password

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

AWS ECR (Elastic Container Registry)

Trivy uses AWS SDK. You don't need to install aws CLI tool. You can use AWS CLI's ENV Vars.

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: Run Trivy vulnerability scanner
        uses: aquasecurity/trivy-action@master
        with:
          image-ref: 'aws_account_id.dkr.ecr.region.amazonaws.com/imageName:${{ github.sha }}'
          format: 'sarif'
          output: 'trivy-results.sarif'
        env:
          AWS_ACCESS_KEY_ID: key_id
          AWS_SECRET_ACCESS_KEY: access_key
          AWS_DEFAULT_REGION: us-west-2

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

GCR (Google Container Registry)

Trivy uses Google Cloud SDK. You don't need to install gcloud command.

If you want to use target project's repository, you can set it via GOOGLE_APPLICATION_CREDENTIAL.

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: 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'
        env:
          GOOGLE_APPLICATION_CREDENTIAL: /path/to/credential.json

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

Self-Hosted

BasicAuth server needs TRIVY_USERNAME and TRIVY_PASSWORD. if you want to use 80 port, use NonSSL TRIVY_NON_SSL=true

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: 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'
        env:
          TRIVY_USERNAME: Username
          TRIVY_PASSWORD: Password

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