Dockerfile

# syntax=docker/dockerfile:1
# ---------------------------------------------------------------------------
# "By Petition" / "Laid Before the Assembly" — Django portal image.
#
# Single glibc stage. No Node: django-tailwind 4.x is standalone
# (pytailwindcss), so the old Volta-built-from-Rust bootstrap is gone.
#
# Built to run under the standard CHNM compose stack, whose app service does:
#   command: sh -c "uv run manage.py migrate && uv run manage.py runserver 0.0.0.0:8000"
# Compose `command` overrides CMD but NOT ENTRYPOINT, so this image has NO
# ENTRYPOINT and keeps `uv` on PATH. Config is env-driven (config/settings.py);
# the SQLite database lives on a mounted volume (SQLITE_PATH).
# ---------------------------------------------------------------------------

# No Docker HEALTHCHECK: this site doesn't use the autoheal sidecar. The app
# still exposes /health/ (liveness JSON) for manual or external polling.

# No ENTRYPOINT: the compose `command` (sh -c "... uv run ...") runs verbatim.
# This default CMD just makes a bare `docker run` self-sufficient.
