Refactor things to use explicit names, and put in a trap to cleanup after any errors. Currently, if the build/run/export steps fail, it leaves behind images which eventually clog things to the point podman won't run any more (see also https://github.com/containers/podman/pull/12233 about errors seen due to this) Change-Id: Ib328a07ad67e3f71f379fbf34ae7ef74e212ef1c
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_PODMAN_ROOT to 1 to
run podman as root.
