# 2026-04-12 — Dockerize all containers

**Timestamp:** 2026-04-12T15:00:00

## Summary

Added proper Dockerfiles for backend and frontend. Split compose setup into production (`docker-compose.yml`) and development (`docker-compose.dev.yml`) modes. Updated README to reflect new container architecture.

## Files Added

- `backend/Dockerfile` — multi-stage build: pip install in builder stage, minimal python:3.12-slim runtime; runs uvicorn in production mode
- `frontend/Dockerfile` — multi-stage build: Node 20 Alpine builds the Vite bundle, nginx:alpine serves the static files
- `frontend/nginx.conf` — nginx config for SPA fallback routing and `/api/` reverse proxy to the backend container
- `docker-compose.dev.yml` — development overrides: mounts source for hot reload, uses Vite dev server instead of nginx

## Files Modified

- `docker-compose.yml` — rewritten: proper `build.context` + `dockerfile` references, health check on db, `depends_on` with `condition: service_healthy`, env var interpolation via `${VAR:-default}`, frontend now served on port 80 via nginx
- `README.md` — updated Current State, added Containers table, replaced install options with Production / Development / Local sections
