Since the ironic-agent element builds the ramdisk and extracts the kernel itself, there's no need to actually generate an image at the end of the process. Previously the unnecessary image was being deleted, but this wastes a bunch of time compressing and converting the image. It's better to just not create the image at all. This change adds a noop element called no-final-image that disk-image-create looks for in the element list and, if found, will cause it to skip the final image generation. This is more flexible than the previous ironic-agent-specific method that would have required changes to disk-image-create for every element that wanted to behave similarly. Note that this cannot be done using an environment variable, because element environments.d entries do not propagate out to disk-image-create. It also doesn't make sense as a user option because it should be set by the element author, not the user. Change-Id: I168feb18f0d578b3babbe4784d3ef75e755e1ebd
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.
