CircleCI is a continuous integration and delivery platform.
The CNB project maintains an integration, called an orb, which allows users to run pack commands inside their pipelines.
To use the CNB integration, you need to declare that you are using the buildpacks/pack orb, and then use
it in your workflow.
For instance, your .circleci/config.yml file may look like this:
version: 2.1
orbs:
  pack: buildpacks/pack@0.2.0
workflows:
  main:
    jobs:
      - pack/build:
          image-name: sample
          builder: 'paketobuildpacks/builder:base'
