This switches the code to use networkx for the digraph implementation. Note that the old implementation specifically isn't removed in this change -- for review clarity. It will be replaced by a base class that defines things properly to the API described below. Plugins return a node object with three functions get_name() : return the unique name of this node get_nodes() : return a list of nodes for insertion into the graph. Usually this is just "self". Some special things like partitioning add extra nodes at this point, however. get_edges() : return a tuple of two lists; edges_from and edges_to As you would expect the first is a list of node names that points to us, and the second is a list of node names we point to. Usually this is only populated as ([self.base],[]) -- i.e. our "base" node points to us. Some plugins, such as mounting, create links both to and from themselves, however. Plugins have been updated, some test cases added (error cases specifically) Change-Id: Ic5a61365ef0132476b11bdbf1dd96885e91c3cb6
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.
