Summary of Changes

Hello @runephilosof-abtion, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request aims to fix and improve the worker Docker build process by upgrading its core components. It involves updating the Python runtime environment to version 3.11 and modernizing the base Debian operating system to Trixie. Additionally, it ensures that all required system-level dependencies, including new XML and XSLT development libraries, are properly installed for a robust and successful build.

Highlights

• Python Version Upgrade: The base Python version for the worker Docker image has been upgraded from 3.8 to 3.11. This update was specifically chosen to avoid known compatibility issues with numpy that arise in Python 3.12 and newer versions.
• Debian Base Image Update: The underlying Debian distribution for the Docker image has been updated from buster to trixie, modernizing the operating system environment.
• Dependency Additions: Added libxml2-dev and libxslt-dev to the apt-get install command to ensure necessary build dependencies are present for the worker environment.

Code Review

This pull request updates the worker's Docker image to use Python 3.11 and a newer Debian release (trixie), which is a great step towards keeping the environment up-to-date. The addition of necessary build dependencies like libxml2-dev and libxslt-dev is also a good fix. I've added one suggestion to further optimize the Docker image by reducing its size, following common best practices.

[gemini-code-assist]

This RUN command can be optimized to reduce the final Docker image size. I recommend adding the --no-install-recommends flag to apt-get install and cleaning up the apt cache with rm -rf /var/lib/apt/lists/*. These are common best practices for creating smaller Docker images.

RUN apt-get update && \
    apt-get install -y -q --no-install-recommends \
        build-essential \
        curl \
        libpq-dev \
        libxml2-dev \
        libxslt-dev \
        openssl \
        python3-dev \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*

[runephilosof-abtion]

@gemini-code-assist As far as I know rm -rf /var/lib/apt/lists/* is necessary because the base image takes care of it.

[gemini-code-assist]

Thanks for the comment, @runephilosof-abtion! I appreciate you bringing this up.

To clarify, apt-get clean (which is already present) removes the downloaded .deb package files from the cache. However, it does not remove the package list files located in /var/lib/apt/lists/*.

Even with slim base images like python:3.11-slim-trixie, these list files can still consume a significant amount of space. Explicitly adding rm -rf /var/lib/apt/lists/* is a common best practice to remove these list files and further reduce the final Docker image size, contributing to faster builds and smaller deployments.

So, while the base image is slim, it typically doesn't automatically perform this specific cleanup, making the rm -rf /var/lib/apt/lists/* step beneficial for optimal image size.

The only thing I have tested is that docker can build.
I haven't tried running it.
