Currently we pass a reference to a global "rollback" list to create() to keep rollback functions. Other nodes don't need to know about global rollback state, and by passing by reference we're giving them the chance to mess it up for everyone else. Add a "add_rollback()" function in NodeBase for create() calls to register rollback calls within themselves. As they hit rollback points they can add a new entry. lambda v arguments is much of a muchness -- but this is similar to the standard atexit() call so with go with that pattern. A new "rollback()" call is added that the driver will invoke on each node as it works its way backwards in case of failure. On error, nodes will have rollback() called in reverse order (which then calls registered rollbacks in reverse order). A unit test is added to test rollback behaviour Change-Id: I65214e72c7ef607dd08f750a6d32a0b10fe97ac3 |

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.
