Summary of Changes

Hello @giohappy, 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 modifies the Dockerfile for Ubuntu-based images to ensure backward compatibility for existing projects. It specifically addresses issues arising from the recent upgrade to Ubuntu 24.04 and the adoption of Python virtual environments, which altered the default path for the 'invoke' command. By installing the 'invoke' package and creating a symbolic link to a well-known global path, this change allows existing 'entrypoint.sh' scripts to continue functioning without modification, streamlining the upgrade process for users.

Highlights

• Install 'invoke' package: The 'invoke' Python package (version 2.2.0) is now explicitly installed during the Docker image build process.
• Create symlink for 'invoke' command: A symbolic link is created from the 'invoke' executable, located within the Python virtual environment, to '/usr/local/bin/invoke'. This ensures the command is globally accessible.
• Maintain compatibility for existing projects: This change addresses compatibility issues for existing GeoNode projects that rely on '/usr/local/bin/invoke', preventing the need to modify their 'entrypoint.sh' scripts after the upgrade to Ubuntu 24.04 and the introduction of Python virtual environments.

Code Review

This pull request adds a symlink for the invoke command to maintain backward compatibility for existing projects after an upgrade. The changes are in the Dockerfile. I've provided a couple of suggestions to improve the robustness and readability of the Dockerfile instructions.

[gemini-code-assist]

For better readability, consistency, and efficiency, it's a good practice to upgrade pip first, and then install all packages in a single pip install command. This reduces the number of processes spawned within the RUN instruction and makes the package list easier to manage.

RUN pip install --upgrade pip && \
    pip install \
        uwsgi \
        wheel==0.38.1 \
        invoke==2.2.0 \
        GDAL==3.8.4

[gemini-code-assist]

Using which invoke makes this command dependent on the PATH environment variable. For better robustness and to make the Dockerfile more explicit, it's recommended to use the absolute path to the invoke executable within the virtual environment.

RUN ln -s /usr/src/venv/bin/invoke /usr/local/bin/invoke
