summary
Explains how cloudnative buildpacks handle tens of millions of images by keeping app layers unchanged and only swapping base OS layers via a rebase that edits the OCI image metadata (a JSON text file) so app layer SHAs stay the same and nodes can reuse cached layers. Shows concrete tooling: install the pack CLI (Homebrew or GitHub) and pick a Heroku Paketo Google builders bundle to produce layered images that avoid full rebuilds and speed deployments.
