This is a minimal clone of the official Python Docker image withfree-threading enabled (--disable-gil).

Use standalone builds like the ones from Astral:
https://github.com/astral-sh/python-build-standalone/

Example usage:
https://github.com/DNALinux/OmicsContainers/blob/main/Python/3.13.1-no_GIL/Dockerfile

Note: I am lazy and don’t keep up with updates

Literally just one thing:
In the CPython build step, I've added this flag:

–disable-gil

Everything else is the same as the official image.

Free-threading (aka “no-GIL”) is experimental in Python 3.13+. If you want to try running Python with GIL disabled in a container, this image gives you a head start.

If you don’t trust random images from the internet (you shouldn’t), you can build it yourself:

1. Start from the official Python Dockerfile (e.g.,https://github.com/docker-library/python)
2. Add--disable-gil to the./configure step during CPython build
3. Done.

docker pull ghcr.io/abebus/free-threaded-python-docker-image:main

This is experimental. Things may break. Performance may vary. Use at your own risk.
