Buildpacks is an open-source technology that provides a platform-independent way to build and package applications. They automate the process of transforming source code into a runnable container image. Buildpacks analyze the application source code, detect the language and dependencies, and then create a container image that includes all the necessary components.

KnolX Etiquettes
 Punctuality
Join the session 5 minutes prior to the session start time. We start on
time and conclude on time!
 Feedback
Make sure to submit a constructive feedback for all sessions as it is very
helpful for the presenter.
 Silent Mode
Keep your mobile devices in silent mode, feel free to move out of session
in case you need to attend an urgent call.
 Avoid Disturbance
Avoid unwanted chit chat during the session.

4. History of buildpack.io
 Origins (2011):
− Buildpacks were first used by Heroku in 2011.
− Heroku used them for deploying applications at that time.
 Widespread Adoption:
− Buildpacks became popular and were adopted by many other platforms.
− Notable platforms like Cloud Foundry, Knative, GitLab, and Google App Engine started
using them.
 Introduction of CN Buildpacks (2018):
− In 2018, Pivotal and Heroku created CN Buildpacks.
− These introduced standardized buildpacks and became part of the CNCF platform in
October

5. What are Cloud Native Buildpacks
 Cloud Native Buildpacks (CNB) are a standardized way of building container images. They automate the
process of transforming application source code into container images that can be run in a cloud-native
environment.
 Portable via the OCI standard
 Greater modularity
 Faster builds
 Reproducible image builds
 Unprivileged containers
 Developed in partnership with Heroku
 CNCF project

6. The Goals
Write code
Run apps
Minimal fuss
This has been the goal of app dev teams for the long time.

7. CN Buildpack
Features
 Application detection/validation.
 Vend dependant components (eg: middleware
stack).
 Put application in "stack" (os base)
 Create a configuration
 Define how the application starts
 Output the container
 Use smart caching to enable builds and runtime
images
 Application Binary interface
 Cross repository blob mounitng
 Fast is a feature!
 Local development
Buildpack provide variety of service to
create an appropriate build and run
environment.

8. Buildpack API
Analysis
Detect
Build
Export
 Where an optimal selection of compatible build pack is chosen and a
build plan is created.
 Where metadata about OCI Layers generated during a previous build
are made available to buildpacks.
 Where buildpacks use that metadata to generate only the OCI layers
that need to be replaced.
 Where the remote layers are replaced by the generated layers.

9. Buildpack Platform
 Local CLI -> like pack CLI
 Plugin -> like Buildpack plugin in Tekton
 Cloud app platform -> like Kpack
