Our services run as Python applications inside containers. We currently generate one SBOM from the container image and another from the dependency lockfile, but they never match because the image also includes operating-system packages from the base image and sometimes components compiled during the build. Customers want a single SBOM for each release, and manually merging and deduplicating the documents is becoming tedious. What tools or workflow can capture the Python interpreter, installed wheels, bundled native libraries, and system packages in one pass?

Pay special attention to wheels that bundle shared libraries. Some scanners report the Python package but fail to identify a vendored C or system library inside it. Validate the generated SBOM against a few known images, then add a separate verification step for bundled binaries if those components matter for vulnerability tracking.
Generate the SBOM from the final built image rather than only from the lockfile. That lets the scanner see the Python packages, OS packages installed by the base image, and anything added or compiled during the container build. Treat the release image as the source of truth.
A tool such as Syft can run multiple catalogers against one image, covering both system packages and Python dependencies in a single document. Test it against your pinned wheels, though, because package metadata is not always enough to identify every native component.
