This element installs package to ensure that the resulting image
provides the binaries outlined in posix specification [1]. This solves
some problems such as cron missing from the ubuntu-minimal images, and
hopefully minimizing the problems from similar problems in the future.
This is the image size difference:
Resulting qcow image sizes:
Ubuntu Ubuntu-Minimal Debian Centos7
None 334MB 330MB 352MB 470MB
Posix 353MB 375MB
Posix+ 354MB 374MB 406MB 471MB
Posix+ = Posix + gcc + cssc

Image building tools for OpenStack
diskimage-builder is a flexible suite of components for
building a wide-range of disk images, filesystem images and ramdisk
images for use with OpenStack.
This repository has the core functionality for building such images, both virtual and bare metal. Images are composed using elements; while fundamental elements are provided here, individual projects have the flexibility to customise the image build with their own elements.
For example:
$ DIB_RELEASE=trusty disk-image-create -o ubuntu-trusty.qcow2 vm ubuntuwill create a bootable Ubuntu Trusty based qcow2
image.
diskimage-builder is useful to anyone looking to produce
customised images for deployment into clouds. These tools are the
components of TripleO that are
responsible for building disk images. They are also used extensively to
build images for testing OpenStack itself, particularly with nodepool.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.
