For Linux environments, the installation script provides the most reliable method, automatically detecting your system architecture and downloading the appropriate binary. This approach works consistently across different distributions, from Ubuntu and CentOS to Alpine Linux containers.
macOS users benefit from Homebrew integration, which handles dependency management and keeps Trivy updated alongside other development tools. The Homebrew installation also configures PATH variables automatically, eliminating common setup issues that can occur with manual installations.
Windows users have multiple options, with Chocolatey providing the most streamlined experience for those already using package managers. Alternatively, downloading binaries directly from GitHub releases offers more control over installation locations and version selection.
The Docker installation option deserves special attention for teams working in containerized environments. This approach ensures consistent Trivy versions across different development machines and CI/CD systems, while the volume mount provides access to the Docker socket for container image analysis.
After installation, verifying functionality with trivy --version confirms that the installation completed successfully and displays the current version information. This step is particularly important in CI/CD environments where installation failures might not be immediately apparent.
Basic SBOM Generation Commands
Understanding Trivy’s command structure forms the foundation for effective SBOM generation across different types of software artifacts. The basic syntax follows a consistent pattern that makes it easy to adapt commands for different scanning targets and output requirements.
Trivy outputs SBOMs in CycloneDX or SPDX—learn how to interpret these formats and why CycloneDX is preferred for vulnerability tracking in firmware projects.
| Target Type | Command | Use Case |
|---|---|---|
| Container Image | trivy sbom nginx:latest | Scan public/private container images |
| Filesystem | trivy sbom fs /path/to/project | Analyze local project dependencies |
| Git Repository | trivy sbom repo https://github.com/user/repo | Scan remote repositories |
| Archive File | trivy sbom archive app.tar.gz | Analyze compressed artifacts |
| SBOM File | trivy sbom sbom://path/to/sbom.json | Process existing SBOM files |
Container image scanning represents the most common use case, particularly in environments where Docker containers form the primary deployment mechanism. The command trivy sbom nginx:latest demonstrates the basic syntax, automatically detecting and analyzing all layers within the specified image.
Filesystem scanning provides comprehensive analysis of local development projects, examining package manager files, lock files, and installed dependencies. This approach proves particularly valuable during development phases when you need to understand dependency relationships before containerization.
Git repository analysis enables remote scanning without requiring local checkouts, making it ideal for CI/CD pipelines that need to analyze code before building artifacts. The repository scanning capability supports both public and private repositories with appropriate authentication.
“Trivy recently added support for generating SBOMs as a top-level command in the CycloneDX format, an industry-wide SBOM standard, to simplify software inventory creation.”
