Building Multi-Architecture Images with Buildpacks

Explore the world of multi-architecture image building using Buildpacks in this informative conference talk. Dive into the key architecture of Buildpacks and understand the separation of concerns between buildpack and platform API. Examine two platform implementations in depth: the stand-alone buildpack builder (pack) and the Kubernetes native buildpack service (kpack). Learn how these platforms utilize the lifecycle component to transform source applications into images. Delve into the challenges and potential solutions for supporting multi-architecture builds, particularly for x86_64 and ARM64 architectures. Consider the implications of producing multi-architecture output on x86_64 build platforms and discuss the feasibility of implementing these changes in pack and kpack while maintaining backward compatibility.
