Syft

A CLI tool and Go library for generating a Software Bill of Materials (SBOM) from container images and filesystems. Exceptional for vulnerability detection when used with a scanner like Grype.

Features

• Generates SBOMs for container images, filesystems, archives (see the docs for a full list of supported scan targets)
• Supports dozens of packaging ecosystems (e.g. Alpine (apk), Debian (dpkg), RPM, Go, Python, Java, JavaScript, Ruby, Rust, PHP, .NET, and many more)
• Supports OCI, Docker, Singularity, and more image formats
• Works seamlessly with Grype for vulnerability scanning
• Multiple output formats (CycloneDX, SPDX, Syft JSON, and more) including the ability to convert between SBOM formats
• Create signed SBOM attestations using the in-toto specification

Installation

The quickest way to get up and going:

curl -sSfL https://get.anchore.io/syft | sudo sh -s -- -b /usr/local/bin

[!TIP] See Installation docs for more ways to get Syft, including Homebrew, Docker, Scoop, Chocolatey, Nix, and more!

The basics

See the packages within a container image or directory:

# container image
syft alpine:latest

# directory
syft ./my-project

To get an SBOM, specify one or more output formats:

# SBOM to stdout
syft <image> -o cyclonedx-json

# Multiple SBOMs to files
syft <image> -o spdx-json=./spdx.json -o cyclonedx-json=./cdx.json

Local containers-storage images

On Linux, syft can scan images from a local containers-storage store (e.g. built with Buildah or Podman) when asked explicitly; plain image references never look there:

syft --from containers-storage localhost/myimage:latest

# rootless stores must be read from inside the builder's user namespace
podman unshare syft --from containers-storage localhost/myimage:latest

This is included in the Linux release binaries. When building from source, add -tags containers_image_openpgp,exclude_graphdriver_btrfs.
