                # Strictly speaking, preloading of Docker images is not required.
                # However, you might want to do this for a couple of reasons:
                # - If the image comes from a private repository, it is much easier to let Concourse pull it,
                #   and then pass it through to the task.
                # - When the image is passed to the task, Concourse can often get the image from its cache.
