ubuntu-minimal

Note: The ubuntu element is likely what you want unless you really know you want this one for some reason. The ubuntu element gets a lot more testing coverage and use.

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_APT_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_APT_KEYRING if that is used as well.
