Set up your GitHub Actions workflow with a specific version of Trivy

# ...
steps:
  - name: Install Trivy
    uses: aquasecurity/setup-trivy@v0.2.0

steps:
  - name: Install Trivy
    uses: aquasecurity/setup-trivy@v0.2.0
    with:
      version: v0.56.1

setup-trivy uses actions/cache under the hood but requires less configuration settings. This caches the trivy binary so that next time you run, instead of downloading the binary it is loaded from the cache. This is not the same cache as other Trivy artifacts such as trivy-db and trivy-java-db.

The cache input is optional, and caching is turned off by default.

Caching is not supported for empty and latest versions!

If you want to enable caching for Linux and MacOS runners, set the cache input to true and specify the version.

steps:
  - name: Install Trivy
    uses: aquasecurity/setup-trivy@v0.2.0
    with:
      version: v0.56.1
      cache: true

action/cache doesn't support absolute path for Windows runners (see here for more details).

To enable caching for Windows runner or if you need to change the Trivy installation directory for other reasons - use path input.

setup-trivy adds trivy-bin directory to avoid caching unnecessary files

steps:
  - name: Install Trivy
    uses: aquasecurity/setup-trivy@v0.2.0
    with:
      version: v0.56.1
      cache: true
      path: "./bins"
