Paketo Buildpacks

What Paketo Buildpacks is
Paketo Buildpacks turns application source code into container images by detecting the language, collecting the dependencies it needs, and assembling a build. Guides cover Java, Node.js, .NET Core, Go, Python, PHP, and Ruby. Built-in caching can speed up rebuilds without requiring advanced build-tool customization. Buildpacks are modular: teams can combine them for an application or use project tooling to create new ones. Configuration can use environment variables, buildpack.yml, bindings, and Procfiles.
For supply-chain visibility, Paketo generates bills of materials in Syft JSON, SPDX JSON, CycloneDX JSON, and a Paketo-specific format. Buildpacks running in CI can patch an image’s OS layer without rebuilding application source code. Paketo stacks run as a dedicated non-root user while building and running applications. Stacks are rebuilt weekly and when packages receive CVE patches; the project aims to release fixes for High and Critical CVEs within 48 hours of a patch release.
The project is community-driven and vendor-neutral. It is free, open-source software for Linux and self-hosted use, with listed integrations including Docker, Kubernetes, CircleCI, GitLab, Tekton, and Spring Boot.
Who it suits
Paketo Buildpacks suits developers and operators who need to build container images from application source, particularly for the languages covered by its guides.
