# osbuild-composer - Containerized OSBuild Composer
#
# This container provides a minimal fedora image with the osbuild-composer
# application installed and configured as default entrypoint.
#
# Build Arguments:
#
#   * OSB_FROM
#       This specifies the host image to use. It must be an RPM-based
#       distribution image with all osbuild-composer requirements
#       pre-installed.
#
#       Example: "docker.io/library/fedora:latest"
#
#   * OSB_RPMREPO
#       Base URL of an RPM repository from which to install osbuild-composer
#       from.
#
#       Example: "https://dl01.fedoraproject.org/pub/fedora/linux/releases/$releasever/Everything/$basearch/os/"
#

# Image arguments must be imported before `FROM`.
ARG             OSB_FROM="docker.io/library/fedora:latest"

# Prepare our host environment.
FROM            "${OSB_FROM}" AS base

# Import build parameters.
ARG             OSB_RPMREPO="https://dl01.fedoraproject.org/pub/fedora/linux/releases/\$releasever/Everything/\$basearch/os/"

# for all sources during the install.
