Deep Dive: Cloud Native Buildpacks
summary
Explains implementing the two required executables detect and build, using the pack CLI to produce OCI images from builder images that contain many buildpacks; buildpacks produce discrete OCI layers with metadata and SHA256 checks so rebuilds skip unchanged layers, and rebasing replaces OS run images for security updates. Demonstrates composing a simple Python/Django buildpack with a Node.js asset buildpack, writing images directly to registries via go-container-registry (no Docker daemon), and notes offline packaged buildpacks (~1 GB) and dynamic builder generation.
