# Dependency graph
requires:
  - phase: 06-01
    provides: Dockerfile with HEALTHCHECK pointing to /health, docker-compose.yml with named volume
provides:
  - /health endpoint for Docker HEALTHCHECK
  - Environment variable documentation (.env.example)
  - Backup script for data volume
  - Docker deployment documentation in README

# Tech tracking
tech-stack:
  added: []
  patterns:
    - Health check with database connectivity verification
    - Docker volume backup via temporary Alpine container

key-files:
  created:
    - src/routes/health/+server.ts
    - .env.example
    - backup.sh
  modified:
    - README.md

key-decisions:
  - "Health check queries database to verify full stack connectivity"
  - "Backup script uses temporary Alpine container to access volume"
  - "Environment variables documented with comments explaining each option"

patterns-established:
  - "Health endpoint pattern: database query for connectivity check, 200/503 responses"
  - "Backup pattern: mount volume read-only, tar czf to timestamped archive"

# Phase 6 Plan 02: Runtime Configuration Summary

**Health check endpoint with database verification, environment documentation, and Docker volume backup script**

## Performance

- **Duration:** 2 min
- **Started:** 2026-02-01T12:22:33Z
- **Completed:** 2026-02-01T12:24:40Z
- **Tasks:** 3
- **Files modified:** 4

## Accomplishments

- /health endpoint returns 200 when database is accessible, 503 on failure
- .env.example documents all configuration options (PORT, ORIGIN, TASKPLANER_DATA_DIR, BODY_SIZE_LIMIT, proxy headers)
- backup.sh creates timestamped tar.gz archives of the Docker volume
- README.md updated with comprehensive Docker deployment section

## Task Commits

Each task was committed atomically:

1. **Task 1: Create health check endpoint** - `de09b14` (feat)
2. **Task 2: Create environment documentation and backup script** - `c92cb3e` (feat)
3. **Task 3: Add Docker deployment section to README** - `f3a5449` (docs)

## Files Created/Modified

- `src/routes/health/+server.ts` - Health check endpoint with database connectivity verification
- `.env.example` - Environment variable documentation with all configuration options
- `backup.sh` - Docker volume backup script creating timestamped archives
- `README.md` - Docker deployment section with quick start, config, backup instructions

## Decisions Made

- Health check performs actual database query (select from entries limit 1) to verify full stack connectivity, not just server responsiveness
- Backup script uses temporary Alpine container to access volume contents, avoiding need for container to be running
- README includes reverse proxy configuration section for nginx/traefik deployments

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Docker deployment is complete and ready for production use
- All Phase 6 (Deployment) objectives met:
  - Dockerfile with multi-stage build and non-root user
  - docker-compose.yml with named volume
  - /health endpoint for container health monitoring
  - Environment documentation
  - Backup script for data preservation
  - README with deployment instructions
