What minor version does docker image python:3.12-slim use?

Any 3.12.X. The image tag is updated with each minor release.

How could it be that the pipeline is grabbing an older python version?

An old version of the image tag is cached on the machine. Because it exists, new version is not fetched. This is a configuration in gitlab-runner, see for example GitLab runner pulls image for every job .

If you intend to use 3.12.3, then the docker python project happens to also have :3.12.3-slim docker tag.

Are you referring to https://hub.docker.com/_/python? These are “Docker Official Images”, not official Python images. The images are provided by Docker Community, not by the PSF or Python community.

A while ago debian started to build python without using a libpython. They claimed that that change made starting python faster. May be that is the difference? Otherwise it could be differences in compiler optimisation options used.

Docker image python:3.12-alpine behaves different on Windows and Debian - Stack Overflow

I have build my Fastapi project on my Windows machine and I can successfully run it and build the image. But when I want to run the project on a Raspberry Pi 4 with Debian 12 Bookworm with docker --version > v24.0.7 it fails while telling me that it cannot find a C compiler (gcc). It fails at the step where pip installs the packages from requirements.txt. ...

February 12, 2024 - Multi-stage Docker builds allow you to break up your Dockerfiles into several stages. For example, you can have a stage for compiling and building your application, which can then be copied to subsequent stages. Since only the final stage is used to create the image, the dependencies and tools associated with building your application are discarded, leaving a lean and modular production-ready image. ... # temp stage FROM python:3.12.2-slim as builder WORKDIR /app ENV PYTHONDONTWRITEBYTECODE 1 ENV PYTHONUNBUFFERED 1 RUN apt-get update && \ apt-get install -y --no-install-recommends gcc COPY requirements.txt .

. When you deploy a container image to Lambda, Lambda automatically defines a default Linux user with least-privileged permissions.
