Datadog-Sbom-Generator

This repository contains the source code of Datadog's SBOM Generator. Its goal is to scan a cloned repository folder to extract dependencies which would be installed on your systems and produce a CycloneDX SBOM out of it.

If you're interested in this repository, you might be interested in Setting up Software Composition Analysis in your repositories.

How to install

1. Go to the release page
2. Select the version you want to use (or use the latest version)
3. Download the asset depending on your operating system and your CPU architecture
4. Unzip the asset

Running the scanner

To scan a repository folder and generate a SBOM, you can use this command:

datadog-sbom-generator scan -o "/tmp/sbom.json" "/path/to/directory"

For detailed documentation on all commands and options, see USAGE.md.

You can also get help directly from the command line:

datadog-sbom-generator --help
datadog-sbom-generator scan --help

Supported package managers

This tool sources all dependencies by parsing package manager files. As new package managers appears everyday, we do not support all of them. Here's a list of supported package managers:

Limitations

Datadog SBOM Generator reads package manager dependencies declaration files or their lock files. It means it can only scan dependencies which are declared in a standard and enforced way by each supported dependency manager.

We will detail here any known limitations by language.

Python

This tool only supports extracting packages from:

• requirements*.txt
• Pipfile.lock
• poetry.lock
• pdm.lock
• uv.lock

This tool only supports enriching information from the following package manager declaration files:

• Pipfile
• pyproject.toml

Java

Maven

• This tool only supports extracting packages and locations from pom.xml.
• It can only scan pom.xml files which are stored in the same repository.
• If a pom file defines a parent that is not stored in the repository or is an artifact hosted by an artifact registry, the scanner will try to download it from Maven central. If the scanner cannot locate it there, or cannot access it, it won't be able to resolve the version.

Gradle

• This tool only supports extracting packages from gradle.lockfile.
• This tool only supports package information enrichment from build.gradle and gradle/verification-metadata.xml files.

Javascript and Typescript

NPM, Yarn and PNPM have workspace support

NPM

• This tool only supports extracting packages from package-lock.json.
• This tool only supports package information enrichment from package.json.

Yarn

• This tool only supports extracting packages from yarn.lock.
• This tool only supports package information enrichment from package.json.

PNPM

• This tool only supports extracting packages from pnpm-lock.yaml.
• This tool only supports package information enrichment from package.json.

.Net

Nuget

• This tool supports extracting packages from packages.lock.json and *.csproj.
• This tool only supports package information enrichment from *.csproj when parsing packages.lock.json.
• Inside a .csproj file:
  • Templatization is not supported.
  • Including other csproj is not supported.

Ruby

Bundler

• This tool only supports extracting packages from Gemfile.lock.
• This tool only supports package information enrichment from Gemfile and *.gemspec.
• If the version of a package is defined in a variable, the location reported by the scanner will be the usage of the variable.
• Dependencies sourced from Git repositories won't have any version reported.

C++

Conan

• This tool only supports extracting packages from conan.lock.

Rust

Crates

• This tool only supports extracting packages from Cargo.lock.
