Diskimage-builder Documentation

diskimage-builder is a tool for automatically building customized operating-system images for use in clouds and other environments.

It includes support for building images based on many major distributions and can produce cloud-images in all common formats (qcow2, vhd, raw, etc), bare metal file-system images and ram-disk images. These images are composed from the many included elements; diskimage-builder acts as a framework to easily add your own elements for even further customization.

diskimage-builder is used extensively by the TripleO project and within OpenStack Infrastructure.
