#
# This script expects Podman to be installed on the system and
# that the user is logged in with `podman login` to the target
# repository.
#
# This script expects one or two parameters, it will query for 
# the PROJECT if not provided.  It expects these parameters
# in order:
#     PROJECT  (buildah, podman or skopeo)
#     AUTHFILE (Location of the authfile created by podman login)
#
# It then builds the quay.io/container/${PROJECT}:latest, 
# quay.io/${PROJECT}/stable:latest, quay.io/${PROJECT}/upstream:latest,
# and the quay.io/${PROJECT}/testing:latest container images.
# It then pushes the images to those repos.
#
# This script can be run via cron to build and push the images
# on a regular basis.  Entries like this within "crontab -e" would 
# create each of the images for the specified project at 8:00,
# 9:00 and 10:00 a.m. successively.
# The entries assume an auth.json file has been created using the
# `podman login quay.io` command as root.  If run as a rootless
# user the '0' in the location would need to be changed to the uid
# of the user.  This also assumes a copy of this file in the
# /root/quay.io directory.
