# Build a Podman container image from the latest
# upstream version of Podman on GitHub.
# https://github.com/containers/podman
# This image can be used to create a secured container
# that runs safely with privileges within the container.
# The containers created by this image also come with a
# Podman development environment in /root/podman.
