If $PROGRAMMING_LANGUAGE = go, you might be looking for https://github.com/containers/storage which can create layers, images, and so on. I think `Store` is the main entry: https://pkg.go.dev/github.com/containers/storage#Store

Buildah uses it: https://github.com/containers/buildah/blob/main/go.mod#L27C2...

Edit: buildkit seems to be the same, used by docker, but needs a daemon?
