Hello, and thank you for your great Work @Gadgetoid

This repo is a nice workaround for people who need GPIO inside Docker for Raspberry Pi 5.

But please consider creating a Pull request in official Repo: https://github.com/joan2937/lg/pulls

So maybe it will accepted and you got the official lgpio repaired.

I tried 😭

Actual packaging and distribution of lg is handled by others, and there's a fork where I brought a PR attempting to solve this problem to their attention: https://github.com/gpiozero/lg/pull/1

I think this repository is about the closest you'll get to a solution. I suppose we could huck it up onto PyPI under another name 😆 Though I'd rather work with and not against my peers.

While being happy that the package got installed and creating this post, I got another issue, that I get error when using gpiozero in python code:

/usr/local/lib/python3.11/site-packages/gpiozero/devices.py:300: PinFactoryFallback: Falling back from lgpio: No module named 'lgpio'
  warnings.warn(

this is my dockerfile:

ENV PYTHONUNBUFFERED=1 \
    PIP_DISABLE_PIP_VERSION_CHECK=1 \
    PYTHONDONTWRITEBYTECODE=1 \

# Set the working directory inside the container

# Copy requirements.txt to the container and install Python dependencies

RUN pip install pigpio gpio gpiozero
RUN pip install https://github.com/Gadgetoid/PY_LGPIO/releases/download/0.2.2.0/lgpio-0.2.2.0.tar.gz

# Copy the rest of the application code to the container
COPY . .

# Ensure the entrypoint script is executable
RUN chmod +x ./entrypoint.sh

# Expose the port the app runs on
EXPOSE 8010

ENTRYPOINT ["./entrypoint.sh"]
CMD ["supervisord", "-c", "/supervisord_docker.conf"]

the code runs fine on Raspberry Pi 5 root, but if running docker container with priviliged mode, it doesnt seem to work. Any Ideas, whats wrong?
