A Software Bill Of Materials (SBOM) is analogous to a packing list for a shipment. It lists all the components that make up the software, or were used to build it. For container images, this includes the operating system packages that are installed (for example, ca-certificates) along with language-specific packages that the software depends on (for example, Log4j). The SBOM could include a subset of this information or even more details, like the versions of components and their source.
It is available as a plugin with the latest docker desktop software.
