Test case:

#echo -e "pandas\nipykernel" > requirements.txt

# python -m ensurepip -U && python -m pip install pipx && \
# pipx install --include-deps jupyter-repo2docker repo2podman
# or # python -m pip install -U jupyter-repo2docker repo2podman
repo2docker --engine=podman -E -p 8888:8888 --debug -e NB_USER=jovyan -e NB_UID=1000 --user-name=jovyan .
podman image ls             # TODO: parse "Successfully tagged localhost/r2d-2e1736948146:latest"
podman run  --rm -it -p 8888:8888 --security-opt=label=disable localhost/r2d-2e1736948146
