## QA Fixes Applied ### Critical Issues Fixed: 1. **Frontend health check** (frontend/Dockerfile:60-61, docker-compose.yml:44) - **Problem**: wget not installed in node:20-alpine base image - **Fix**: Replaced wget with native Node.js http request - **New healthcheck**: Uses node built-in http module 2. **Database path inconsistency** (Dockerfile:24,27, docker-compose.yml:12) - **Problem**: Dockerfile created /data but used ./data (relative) while docker-compose mounted to /app/data - **Fix**: Changed Dockerfile to create /app/data and use absolute path sqlite+aiosqlite:////app/data/apc_controller.db ### Medium Issues Fixed: 3. **Backend curl timeout** (Dockerfile:35, docker-compose.yml:20) - Added --max-time 5 to curl health check commands 4. **Database migrations on startup** (docker-entrypoint.sh, Dockerfile:38-39) - Created docker-entrypoint.sh that runs alembic upgrade head before starting uvicorn ### Verification: - docker compose config validates successfully - Backend tests: 139 passed - Frontend tests: 66 passed

[QA FAILED] Critical issues found in Docker implementation: ## Critical Issues (Must Fix): 1. **Frontend health check fails** - wget not installed in node:20-alpine image (frontend/Dockerfile:60-61) 2. **Database path inconsistency** - Dockerfile creates /data but docker-compose mounts /app/data ## Medium Issues (Should Fix): 3. Backend curl health check missing timeout 4. No database migrations run on startup 5. No Docker usage documentation ## Impact: - Frontend container will report unhealthy status - Health checks will fail causing docker-compose depends_on to potentially fail - Implementation cannot be considered working until wget is installed or health check is changed ## Evidence: Detailed QA report available at /tmp/qa-APC-23.md with full analysis, verification checklist, and recommended fixes. **Estimated fix time:** 15-30 minutes for critical issues, full testing requires Docker daemon. See full report for complete analysis and recommended fixes.

## Implementation Summary ### Changes Made 1. **Backend Dockerfile** (`Dockerfile`): - Based on `python:3.12-slim` - Uses `uv` for fast package installation - Exposes port 8000 - Health check on `/health` endpoint - Database path configurable via `DATABASE_URL` env var 2. **Frontend Dockerfile** (`frontend/Dockerfile`): - Multi-stage build (deps → builder → runner) - Based on `node:20-alpine` - Uses Next.js standalone output mode for minimal image size - Non-root user for security - Health check with wget 3. **Docker Compose** (`docker-compose.yml`): - Orchestrates both services - SQLite volume (`sqlite_data`) for data persistence - Internal network (`apc-network`) for container communication - Environment variable passthrough for all config options - Frontend depends on backend health check passing 4. **Configuration Updates**: - Added `output: "standalone"` to `frontend/next.config.ts` for Docker compatibility - Added `.dockerignore` files to optimize build context ### Files Added/Modified - `Dockerfile` - Backend container definition - `frontend/Dockerfile` - Frontend container definition - `docker-compose.yml` - Service orchestration - `.dockerignore` - Backend build context filter - `frontend/.dockerignore` - Frontend build context filter - `frontend/next.config.ts` - Added standalone output - `frontend/public/.gitkeep` - Required by Next.js Dockerfile ### Verification - Docker compose config validated successfully - All backend tests pass (139 tests) - All frontend tests pass (66 tests) - Frontend standalone build works correctly ### Usage \`\`\`bash # Start all services docker compose up # Build and start (detached) docker compose up -d --build # Stop services docker compose down \`\`\` Services will be accessible at: - Frontend: http://localhost:3000 - Backend: http://localhost:8000
