Cloud Native Buildpacks

aid: cloud-native-buildpacks
name: Cloud Native Buildpacks
description: Cloud Native Buildpacks (CNB) is a CNCF-graduated specification and set of tooling for transforming application
  source code into OCI images that can run on any cloud. The project unifies the Heroku and Cloud Foundry buildpack ecosystems
  around an open standard for detection, build, and image export. The reference implementation lifecycle, the pack CLI for
  local builds, the kpack server-side builder, and a registry of distribution buildpacks together form the CNB ecosystem.
  CNB is built around a documented Buildpack API, Platform API, and Distribution API, all versioned and published in the github.com/buildpacks
  specifications.

  description: The Buildpack API is the contract between a buildpack and the lifecycle. It defines the detect and build executables,
    layers, build-plan provisions and requirements, and image extension lifecycle that buildpack authors implement to participate
    in a CNB build.

  description: The Platform API is the contract between the CNB lifecycle and a platform such as pack, kpack, or a CI runner.
    It defines how builders, stacks, run images, and inputs are passed to the lifecycle phases (analyze, detect, restore,
    build, export, and rebase) and how outputs are consumed.

    type: Specification
  description: The Distribution API specifies how buildpacks and builders are packaged as OCI artifacts, signed, and distributed
    through OCI registries. It also covers how meta-buildpacks compose other buildpacks and how stacks and run images are
    referenced.
