When an archive held two entries at one path, the resolver kept the first, and this was documented as intended. Everything that actually unpacks the archive keeps the last: `tar` (and `tar -r` appends updates), OCI layer application, and the legacy java path's `ContentsFromZip`. So a jar could carry a `pom.properties` reporting 2.17.1 ahead of one installing 2.14.0, and the SBOM would show the former. - a later regular file, link or other non-directory entry now replaces the earlier one, refunding its in-memory bytes - a file/directory clash at one path still keeps the first, since swapping kinds would mean re-parenting what is already under it Signed-off-by: Alex Goodman <wagoodman@users.noreply.github.com>
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.
