Installation
|
|
============
|
|
|
|
Diskimage-builder can either be run directly out of the source repository or
|
|
installed via pip. If you plan on doing development on diskimage-builder or
|
|
the elements then we recommend you run the tool out of the source repository
|
|
as this installation requires minimal extra effort and does not require an
|
|
extra install step for your changes to take effect.
|
|
|
|
Once installed, you will be able to :doc:`build images <building_an_image>`
|
|
using disk-image-create and the elements included in the main diskimage-builder
|
|
repository.
|
|
|
|
|
|
Requirements
|
|
------------
|
|
|
|
Most image formats require the qemu-img tool which is provided by the
|
|
qemu-utils package on Ubuntu/Debian or the qemu package on
|
|
Fedora/RHEL/opensuse.
|
|
|
|
Some image formats, such as VHD, may require additional tools. Please see
|
|
the disk-image-create help output for more information.
|
|
|
|
Individual elements can also have additional dependencies for the build host.
|
|
It is recommended you check the documentation for each element you are using
|
|
to determine if there are any additional dependencies.
