⚡ Find threats in files or containers at lightning speed ⚡

This is a GitHub Action for invoking the Grype scanner and returning the vulnerabilities found, and optionally fail if a vulnerability is found with a configurable severity level.

Use this in your workflows to quickly verify files or containers' content after a build and before pushing, allowing PRs, or deploying updates.

The action invokes the grype command-line tool, with these benefits:

• Runs locally, without sending data outbound - no credentials required!
• Speedy scan operations
• Scans both paths and container images
• Easy failure evaluation depending on vulnerability severity

The example workflows have lots of usage examples for scanning both containers and directories.

By default, a scan will produce very detailed output on system packages like an RPM or DEB, but also language-based packages. These are some of the supported packages and libraries:

Supported Linux Distributions:

• Alpine
• BusyBox
• CentOS and RedHat
• Debian and Debian-based distros like Ubuntu

Supported packages and libraries:

• Ruby Bundles
• Python Wheel, Egg, requirements.txt
• JavaScript NPM/Yarn
• Java JAR/EAR/WAR, Jenkins plugins JPI/HPI
• Go modules

The simplest workflow for scanning a localbuild/testimage container:

- name: Set up Docker Buildx
  uses: docker/setup-buildx-action@v2

- name: build local container
  uses: docker/build-push-action@v4
  with:
    tags: localbuild/testimage:latest
    push: false
    load: true

- name: Scan image
  uses: anchore/scan-action@v3
  with:
    image: "localbuild/testimage:latest"

To scan a directory, add the following step:

- name: Scan current project
  uses: anchore/scan-action@v3
  with:
    path: "."

The path key allows any valid path for the current project. The root of the path ("." in this example) is the repository root.

Use the sbom key to scan an SBOM file:

- name: Create SBOM
  uses: anchore/sbom-action@v0
  with:
    format: spdx-json
    output-file: "${{ github.event.repository.name }}-sbom.spdx.json"

- name: Scan SBOM
  uses: anchore/scan-action@v3
  with:
    sbom: "${{ github.event.repository.name }}-sbom.spdx.json"

By default, if any vulnerability at medium or higher is seen, the build fails. To have the build step fail in cases where there are vulnerabilities with a severity level different than the default, set the severity-cutoff field to one of low, high, or critical:

With a different severity level:

- name: Scan image
  uses: anchore/scan-action@v3
  with:
    image: "localbuild/testimage:latest"
    fail-build: true
    severity-cutoff: critical

Optionally, change the fail-build field to false to avoid failing the build regardless of severity:

- name: Scan image
  uses: anchore/scan-action@v3
  with:
    image: "localbuild/testimage:latest"
    fail-build: false

The inputs image, path, and sbom are mutually exclusive to specify the source to scan; all the other keys are optional. These are all the available keys to configure this action, along with the defaults:

Assuming your repository has a Dockerfile in the root directory:

name: Container Image CI
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@b4ffde65f46336ab88eb53be808477a3936bae11 # v4.1.1
      - name: Build the container image
        run: docker build . --file Dockerfile --tag localbuild/testimage:latest
      - uses: anchore/scan-action@v3
        with:
          image: "localbuild/testimage:latest"
          fail-build: true

Same example as above, but with SARIF output format - as is the default, the action will generate a SARIF report, which can be uploaded and then displayed as a Code Scanning Report in the GitHub UI.

💡 Code Scanning is a Github service that is currently in Beta. Follow the instructions on how to enable this service for your project.

name: Container Image CI
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@b4ffde65f46336ab88eb53be808477a3936bae11 # v4.1.1
      - name: Build the Container image
        run: docker build . --file Dockerfile --tag localbuild/testimage:latest
      - uses: anchore/scan-action@v3
        id: scan
        with:
          image: "localbuild/testimage:latest"
      - name: upload Anchore scan SARIF report
        uses: github/codeql-action/upload-sarif@v2
        with:
          sarif_file: ${{ steps.scan.outputs.sarif }}

Optionally, you can add a step to inspect the SARIF report produced:

- name: Inspect action SARIF report
  run: cat ${{ steps.scan.outputs.sarif }}

You may add a .grype.yaml file at your repository root for more Grype configuration such as ignoring certain matches.

A sub-action to download Grype.

Input parameters:

Output parameters:

cmd can be referenced in a workflow like other output parameters: ${{ steps.<step-id>.outputs.cmd }}

Example usage:

- uses: anchore/scan-action/download-grype@v3
  id: grype
- run: ${{steps.grype.outputs.cmd}} dir:.

This action makes extensive use of GitHub Action debug logging, which can be enabled as described here by setting a secret in your repository of ACTIONS_STEP_DEBUG to true.
