# 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 th  e task, Concourse can often get the image from its cache.
