In some build environments Docker is already installed - and adding podman is not an option. Add a new variable to toggle this, and rename the now incorrectly titled DIB_CONTAINERFILE_PODMAN_ROOT to just ...RUNTIME_ROOT to match. Change-Id: I677e4f491b40360dceabdf4f2a9e64c7cb493dc7

=============

|
|
Base element for creating images from container files (aka
|
|
Dockerfiles).
|
|
|
|
Usually this element will be called via a more specific distro element
|
|
which provides an environment for building a full image. This element
|
|
will search active elements for a container file located in
|
|
``containerfiles/${DIB_RELEASE}``.
|
|
|
|
Alternatively, to use this element directly supply the path to a
|
|
container file in the environment variable
|
|
``DIB_CONTAINERFILE_DOCKERFILE``.
|
|
|
|
Set ``DIB_CONTAINERFILE_RUNTIME`` to ``docker`` to use Docker for building
|
|
images (default is ``podman``).
|
|
|
|
Set ``DIB_CONTAINERFILE_RUNTIME_ROOT`` to ``1`` to run the runtime
|
|
(Docker or ``podman``, per above) as ``root``.
