It has always been a weird thing that dib is a python package, but is totally driven by the disk-image-create script. It creates this strange division that is hard to explain. This moves disk-image-create to a regular python entry-point Currently, this simply exec()s the original disk-image-create script. However, we now have a (private) interface between disk-image-create written in python and the driver shell script. Here's some things we could do, for example: * Argument parsing is generally nicer in Python, and then end result is mostly just setting environment variables to flag different things in the shell script. I could see us moving the argument-parsing into diskimage_builder.disk_image_create:main() and just setting things in os.environ before the exec()). * I7092e1845942f249175933d67ab121188f3511fd sets IMAGE_ELEMENT_YAML in disk-image-create by calling-back to element-info. We can just call element_dependencies.find_all_elements() in here an export is to os.environ before disk-image-create starts. * remove need for ramdisk-image-create symlink by just exporting IS_RAMDISK based on sys.argv[1] value * you could even unit test some of this :) Change-Id: I69ca3d26fede0506a6353c077c69f735c8d84d28
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.
