        Instead of matching against pulled tags using
        :py:func:`docker.list_tags <salt.modules.dockermod.list_tags>`, this
        function now simply inspects the passed image name using
        :py:func:`docker.inspect_image <salt.modules.dockermod.inspect_image>`
        and returns the first matching tag. If no matching tags are found, it
        is assumed that the passed image is an untagged image ID, and the full
        ID is returned.

    Inspects the specified image name and returns the first matching tag in the
    inspect results. If the specified image is not pulled locally, this
    function will return ``False``.

    name
        Image name to resolve. If the image is found but there are no tags,
        this means that the image name passed was an untagged image. In this
        case the image ID will be returned.

    all : False
        If ``True``, a list of all matching tags will be returned. If the image
        is found but there are no tags, then a list will still be returned, but
        it will simply contain the image ID.
