expand_dependencies() was a public interface so we should try and preserve backwards compat. However, since the interface is really broken, add a new exported function "get_elements" that instack can switch to. This returns the canonical list of elements without duplicates, and gives the path to each element too. This highlighted that the unit tests were really a bit wrong. They're testing inner functions when we have an "API" in the get_elements() function. Convert all unit-tests to use this function instead. Since this is a library call, convert the sys.exit() calls to raised exceptions. Refactor the variable output into a separate function so we can do a sanity check on it. The added flake8 ignores are for the "over-indented for ... indent" which happens a lot with these new longer lines. Most other projects ignore them. This is an alternative proposal to I15609389c18adf3017220fc94552514d195b323a Change-Id: If97bcd21e45de1b5ed91023fdc441a4617051a6b
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.
