With the removal of Python 2.x we can remove the unittest2 compat wrappers and switch to assertCountEqual instead of assertItemsEqual We have been able to use them since then, because testtools required unittest2, which still included it. With testtools removing Python 2.7 support , we will lose support for assertItemsEqual, so we should switch to use assertCountEqual.  - https://bugs.python.org/issue17866  - https://hg.python.org/cpython/rev/d9921cb6e3cd  - testing-cabal/testtools#286  - testing-cabal/testtools#277 Change-Id: I870286a2557e41099597c22dc9747743e1077615

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.
$ DIB_RELEASE=bionic disk-image-create -o ubuntu-bionic.qcow2 vm ubuntu
will create a bootable Ubuntu Bionic based
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.
