Quickstart for running Python using NixOS flox.dev in Docker

gistfile1.txt

# Run Docker image with NixOS and flox:
# https://flox.dev/docs/install-flox/
# docker run --pull always --rm -it ghcr.io/flox/flox
docker run -it ghcr.io/flox/flox

# Then in that shell:
# flox config --set-bool disable_metrics true
cd ~
flox init
flox install python311Packages.python
flox activate

# Which nests into another shell:
python -m venv .venv
source .venv/bin/activate

# I think https://github.com/flox-examples/hello-python is supposed to do that somehow
# but I couldn't figure out the intended commands.
# There is an issue for flox which intends to automagically make Python requirements.txt work:

# Check out this video from DockerCon 2023 about Nix and Docker together:

# The second/main demo of that video used this (which is a Swiss army knife of Docker and Nix features):
