Deep Dive: Cloud Native Buildpacks

on YouTube ↗46m

" summary

Cloud Native Buildpacks produce OCI images from source using the pack CLI and a builder image that bundles a lifecycle, buildpacks and a stack (Heroku uses Heroku-18 stack). Buildpacks emit layered artifacts (separate JDK vs JRE layers, maven cache, launch/process metadata) so rebuilds only transfer changed blobs and a single rebase (swap base OS layer) patches hundreds of apps with one registry upload. Heroku reports running ~10M apps and 23B requests/day.
