The `diskimage-builder` command provides a yaml file based interface to `disk-image-create` and `ramdisk-image-create`. Every argument to these scripts has a YAML equivalent. The command has the following features: - Environment values can be provided from the calling environment as well as YAML - All arguments are validated with jsonschema in the most appropriate YAML type - Schema is self-documenting and printed when running with --help - Multiple YAML files can be specified and each file can have multiple images defined - Entries with duplicate image names will be merged into a single image build, with attributes overwritten, elements appended, and environment values updated/overwritten. A missing image name implies the same image name as the previous entry. - --dry-run and --stop-on-failure flags A simple YAML defintion would resemble: - imagename: centos-minimal checksum: true install-type: package elements: [centos, vm] - imagename: ironic-python-agent elements: - ironic-python-agent-ramdisk - extra-hardware The TripleO project has managed image build options with YAML files and it has proved useful having git history and a diff friendly format, specifically for the following situations: - Managing differences between distros (centos, rhel) - Managing changes in major distro releases (centos-8, centos-9-stream) - Managing the python2 to python3 transition, within and across major distro releases Now that the TripleO toolchain is being retired this tool is being proposed to be used for the image builds of TripleO's successor, as well as the rest of the community. Subsequent commits will add documentation and switch some tests to using `diskimage-builder`. Change-Id: I95cba3530d1b1c6c52cf547338762e33738f7225 |

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=bionic disk-image-create -o ubuntu-bionic.qcow2 vm ubuntuwill create a bootable Ubuntu Bionic 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.
