Pack

Pack is a CLI tool maintained by the CNB project to support the use of buildpacks.

It enables the following functionality:

  1. build an application using buildpacks.
  2. rebase application images created using buildpacks.
  3. Creation of various components used within the ecosystem.

Pack works as both a Command Line Interface (CLI) and a Go library.
