• 🌅 UV

  Install

  1# curl method
  2curl -LsSf https://astral.sh/uv/install.sh | sh
  3
  4# Pip method
  5pip install uv
  

  Quick example

  1pyenv install 3.12
  2pyenv local 3.12
  3python -m venv .venv
  4source .venv/bin/activate
  5pip install pandas
  6python
  7
  8# equivalent in uv
  9uv run --python 3.12 --with pandas python
  

  Usefull

  1uv python list --only-installed
  2uv python install 3.12
  3uv venv /path/to/environment --python 3.12
  4uv pip install django
  5uv pip compile requirements.in -o requirements.txt
  6
  7uv init myproject
  8uv sync
  9uv run manage.py runserver
  

  Run as script

  • Put before the import statements:

  1#!/usr/bin/env -S uv run --script
  2# /// script
  3# requires-python = ">=3.12"
  4# dependencies = [
  5# "ffmpeg-normalize",
  6# ]
  7# ///
  

  Then can be run with uv run sync-flickr-dates.py. uv will create a Python 3.12 venv for us. For me this is in ~/.cache/uv (which you can find via uv cache dir).

• 👾 Pypi Repository

  Pypi Repo for airgap env

  Let’s take as an example py dependencies for Netbox

   1# Tools needed
   2dnf install -y python3.11
   3pip install --upgrade pip setuptool python-pypi-mirror twine
   4
   5# init mirror
   6python3.11 -m venv mirror
   7mkdir download
   8
   9# Get list of Py packages needed
  10curl raw.githubusercontent.com/netbox-community/netbox/v3.7.3/requirements.txt -o requirements.txt
  11echo pip >> requirements.txt
  12echo setuptools >> requirements.txt
  13echo uwsgi >> requirements.txt
  14
  15# Make sure repository CA is installed
  16curl http://pki.server/pki/cacerts/ISSUING_CA.pem -o /etc/pki/ca-trust/source/anchors/issuing.crt
  17curl http://pki.server/pki/cacerts/ROOT_CA.pem -o /etc/pki/ca-trust/source/anchors/root.crt
  18update-ca-trust
  19
  20
  21source mirror/bin/activate
  22pypi-mirror download -b -d download -r requirements.tx
  23twine upload  --repository-url https://nexus3.server/repository/internal-pypi/ download/*.whl --cert /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
  24twine upload  --repository-url https://nexus3.server/repository/internal-pypi/ /download/*.tar.gz --cert /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
  

  Then on target host inside /etc/pip.conf :
