Answer 1

Your Dockerfile should install iptables as well:

FROM ubuntu:16.04

RUN apt-get update -qq \
    && apt-get install -qq -y software-properties-common uidmap \
    && add-apt-repository -y ppa:projectatomic/ppa \
    && apt-get update -qq \
    && apt-get -qq -y install podman \
    && apt-get install -y iptables

# To keep it running
CMD tail -f /dev/null

Then run the command with:

docker run -ti --rm podman:test bash -c "podman --storage-driver=vfs info"

This should give you the response you expect.
