There are times when a much more stripped down base image is desired over the distro cloud images. For instance, Infra would like some base images that do not have cloud-init or really much of anything else. This is easy to accomplish with debootstrap and rinse.

Create a minimal image based on Ubuntu. We default to trusty but DIB_RELEASE is mapped to any series of Ubuntu.
If necessary, a custom apt keyring and debootstrap script can be
supplied to the debootstrap
command via DIB_DEBIAN_KEYRING
and
DIB_DEBIAN_DEBOOTSTRAP_SCRIPT
respectively. Both options require the
use of absolute rather than relative paths.
Use of this element will also require the tool 'debootstrap' to be available on your system. It should be available on Ubuntu, Debian, and Fedora.
The DIB_OFFLINE
or more specific DIB_DEBIAN_USE_DEBOOTSTRAP_CACHE
variables can be set to prefer the use of a pre-cached root filesystem
tarball.
The DIB_DEBOOTSTRAP_EXTRA_ARGS
environment variable may be used to
pass extra arguments to the debootstrap command used to create the
base filesystem image. If --keyring is is used in DIB_DEBOOTSTRAP_EXTRA_ARGS
,
it will override DIB_DEBIAN_KEYRING
if that is used as well.
