# Build a Podman container image from the latest
# upstream version of Podman on GitHub.
# https://github.com/containers/libpod
# 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.

ENV GOPATH=/root/podman

# Install the software required to build Podman.
# Then create a directory and clone from the Podman
# GitHub repository, make and install Podman
# to the container.
# Finally remove the podman directory and a few other packages
# that are needed for building but not running Podman
