Using docker build is slower and needs lots of Dockerfiles, while a single image with a careful script can accept any type of image, either with `-v` to share into `/tmp` for interactive use (where you need the input and a tty, or by adding a tarball for cases where there is no login such as running tests, so you can still use a remote daemon in these cases.
