- Update base image from python3.9 (EOL) to python3.12 - Combine Poetry setup into a single RUN layer - Combine mkdir calls into one - Combine COPY statements where possible - Add docker/prestart.sh to initialize DB on container start (runs 'flask db upgrade' with fallback to 'flask create_db') Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
python3.12 is incompatible with the pinned dependency versions (python-dateutil requires six, distutils removed). python3.11 is supported until October 2027 and works with the current poetry.lock. Upgrading to python3.12 would require updating the dependencies. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Changes
Python 3.9 → 3.12
Python 3.9 reached end-of-life in October 2025. This updates the base image to
python3.12, the latest available tag fortiangolo/uwsgi-nginx-flask.Reduced layer count
RUNlayermkdircalls into oneCOPYstatements where possibleAdd
docker/prestart.shThe base image (
tiangolo/uwsgi-nginx-flask) automatically executes/app/prestart.shbefore starting the server. This is the proper place for DB initialization, rather than running code at module import time (as proposed in #58).Tries
flask db upgradefirst (for setups using Flask-Migrate), falls back toflask create_dbif no migrations are present.
