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.
