Buildpacks transform your application source code to images that can run on any cloud.

What Are Buildpacks?

Buildpacks provide a higher-level abstraction for building apps compared to Dockerfiles.

Specifically, buildpacks:

  • Provide a balance of control that reduces the operational burden on developers and supports enterprise operators who manage apps at scale.
  • Ensure that apps meet security and compliance requirements without developer intervention.
  • Provide automated delivery of both OS-level and application-level dependency upgrades, efficiently handling day-2 app operations that are often difficult to manage with Dockerfiles.
  • Rely on compatibility guarantees to safely apply patches without rebuilding artifacts and without unintentionally changing application behavior.

Buildpacks were first conceived by Heroku in 2011. Since then, they have been adopted by Cloud Foundry and other PaaS such as Gitlab, Knative, Deis, Dokku, and Drie.

The Cloud Native Buildpacks project was initiated by Pivotal and Heroku in January 2018 and joined the Cloud Native Sandbox in October 2018. The project aims to unify the buildpack ecosystems with a platform-to-buildpack contract that is well-defined and that incorporates learnings from maintaining production-grade buildpacks for years at both Pivotal and Heroku.

Cloud Native Buildpacks embrace modern container standards, such as the OCI image format. They take advantage of the latest capabilities of these standards, such as cross-repository blob mounting and image layer "rebasing" on Docker API v2 registries.
