Fixes bug 1184943 Adding an element that allows other elements to register repositories it would like to be retrieved for it. Doing this outside of the chroot allows locally cached repositories to be used. It also gives the ability to d-i-b to specify what revision to use if an alternative to the most recent is required. Effectively allowing a CI system to test d-i-b and elements without being effected by unavailable git repositories or breakages in actively developed source code being used by the elements.

With this element other elements can register source code repositories by
|
|
placing their details in the file source-repository-\*. An example
|
|
of an element "custom-element" that wants to retrieve the ironic source
|
|
from git and pbr from a tarball would be
|
|
|
|
*File : elements/custom-element/source-repository-ironic*
|
|
|
|
#<name> <type> <destination> <location> [<ref>]
|
|
# <ref> defaults to master if not specified
|
|
ironic git /usr/local/ironic git://github.com/openstack/ironic.git
|
|
|
|
*File : elements/custom-element/source-repository-pbr*
|
|
|
|
pbr tar /usr/local/pbr http://tarballs.openstack.org/pbr/pbr-master.tar.gz
|
|
|
|
diskimage-builder will then retrieve the sources specified and place them
|
|
at the directory \<destination\>
|
|
|
|
A number of environment variables can be set by the process calling
|
|
diskimage-builder which can change the details registered by the element, these are
|
|
|
|
DIB_REPOTYPE_<name> : change the registered type
|
|
DIB_REPOLOCATION_<name> : change the registered location
|
|
DIB_REPOREF_<name> : change the registered reference
|
|
|
|
for example if you would like diskimage-builder to get ironic from a local
|
|
mirror you could set DIB_REPOLOCATION_ironic=git://localgitserver/ironic.git
|
|
|
|
Git sources will be cloned to \<destination\>
|
|
|
|
Tarballs will be extracted to \<destination\>. Tarballs should contain a
|
|
single topleval directory, regardless of the name of this top level directory
|
|
it will be renamed to \<destination\>
