  Cloud Native Buildpacks (CNBs) transform application source code into
  OCI-compliant container images that can run on any cloud, without requiring
  Dockerfiles. Initiated by Pivotal and Heroku in January 2018, CNBs are a CNCF
  incubating project licensed under Apache-2.0. They centralize container
  expertise through composable buildpacks, enable layer rebasing for efficient
  OS updates, and generate Software Bills of Materials (SBOM). The pack CLI and
  kpack platform operator are primary integration points.

      The Buildpack API defines the contract between a buildpack and the
      lifecycle that executes it. It specifies detect, build, and export phases,
      layer contribution formats, environment variable handling, and SBOM
      generation interfaces.

      The Platform API defines the contract between a platform (such as pack or
      kpack) and the CNB lifecycle. It covers builder configuration, build
      inputs and outputs, stack definitions, and run image management.
