Docker can export root filesystems, which is what we want out of root elements. Make a very simple passthrough element that will grab a docker image and export it into a root filesystem. Change-Id: Ie1e2d5dd5a61558f100e02c953b18d697a8fe8a2

Base element for creating images from docker containers.
|
|
|
|
This element is incomplete by itself, you'll want to add additional elements,
|
|
such as dpkg or yum to get richer features. At its heart, this element simply
|
|
exports a root tarball from a named docker container so that other
|
|
diskimage-builder elements can build on top of it.
|
|
|
|
The variables `DISTRO_NAME` and `DIB_RELEASE` will be used to decide which
|
|
docker image to pull, and are required for most other elements. Additionally,
|
|
the `DIB_DOCKER_IMAGE` environment variable can be set in addition to
|
|
`DISTRO_NAME` and `DIB_RELEASE` if a different docker image is desired.
