We've not really been using the Focal containerfile, as we move forward jammy is a better choice for keeping stable as we might find some new users for it. Also add binutils to bindep for native bullseye builds (see Icb0e40827c9f8ac583fa143545e6bed9641bf613) Change-Id: I22ebe2bbccaec34180e58996b21e47bfc4f36055
containerfile
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.
Set DIB_CONTAINERFILE_NETWORK_DRIVER to a network driver
of your choice (e.g. host) to use it instead of the default bridge
during build.
