What Paketo Buildpacks is

Paketo Buildpacks turns application source code into container images, with production-ready buildpacks for popular languages and frameworks. Buildpacks detect an application’s language, gather its dependencies, and assemble an image. Guides cover Java, Node.js, .NET Core, Go, Python, PHP, and Ruby. Built-in caching supports faster rebuilds, and modular buildpacks can be composed for an application or created with the project’s tooling. Configuration options include environment variables, buildpack.yml, bindings, and Procfiles. For software supply-chain visibility, Paketo generates bills of materials in Syft JSON, SPDX JSON, CycloneDX JSON, and a Paketo-specific format. In CI, buildpacks can patch an image’s OS layer without rebuilding application source code. Paketo stacks run under a dedicated non-root user and are rebuilt weekly and when packages are patched for CVEs. The project aims to release fixes for High and Critical CVEs within 48 hours of a patch release. Paketo is free and open source for Linux and self-hosted use, and lists compatibility with tools including Docker, Kubernetes, CircleCI, GitLab, and Tekton.
