# Phase 1 Plan 4: HTTPS and Backup Summary
|
|
|
|
**Caddy reverse proxy with self-signed TLS for development, PostgreSQL daily backups with 30-day retention and weekly restore testing**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 3 min
|
|
- **Started:** 2026-01-25T20:17:00Z
|
|
- **Completed:** 2026-01-25T20:20:00Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 5
|
|
|
|
## Accomplishments
|
|
|
|
- Caddy reverse proxy with HTTPS termination and automatic HTTP redirect
|
|
- Security headers configured (HSTS, X-Content-Type-Options, X-Frame-Options)
|
|
- PostgreSQL backup script with integrity verification
|
|
- 30-day backup retention with automatic cleanup
|
|
- Weekly restore test to validate backup usability
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Configure Caddy reverse proxy with HTTPS** - `3c09e27` (feat)
|
|
2. **Task 2: Create PostgreSQL backup script with retention** - `09f8961` (feat)
|
|
|
|
## Files Created/Modified
|
|
|
|
- `Caddyfile` - Caddy configuration with TLS, reverse proxy, and security headers
|
|
- `docker-compose.yml` - Added Caddy service with host networking
|
|
- `scripts/backup-postgres.sh` - Daily backup script with verification and retention
|
|
- `scripts/cron/postgres-backup` - Cron configuration for 2 AM daily backups
|
|
- `.gitignore` - Excludes pycache, env files, backup files
|
|
|
|
## Decisions Made
|
|
|
|
- **Self-signed TLS for development:** Used `tls internal` for local development; production will replace `:443` with actual domain and remove this directive
|
|
- **Host network mode:** Caddy uses `network_mode: host` to reach FastAPI on localhost:8000
|
|
- **Backup at 2 AM:** Low-traffic time for backup operations
|
|
- **30-day retention:** Balanced between storage efficiency and recovery options
|
|
- **Weekly restore test on Mondays:** Validates backups are actually restorable, not just created
|
|
|
|
## Deviations from Plan
|
|
|
|
### Auto-fixed Issues
|
|
|
|
**1. [Rule 3 - Blocking] Fixed pg_restore verification to run in container**
|
|
- **Found during:** Task 2 (Backup script creation)
|
|
- **Issue:** Plan used host pg_restore for verification, but pg_restore only exists in container
|
|
- **Fix:** Changed verification to pipe backup into container via `docker exec -i`
|
|
- **Files modified:** scripts/backup-postgres.sh
|
|
- **Verification:** Backup script completes successfully with verification
|
|
- **Committed in:** 09f8961 (Task 2 commit)
|
|
|
|
---
|
|
|
|
**Total deviations:** 1 auto-fixed (1 blocking)
|
|
**Impact on plan:** Essential fix for backup verification to work. No scope creep.
|
|
|
|
## Issues Encountered
|
|
|
|
- Backend not running during HTTPS verification - expected behavior, Caddy correctly configured to proxy when backend is available
|
|
|
|
## User Setup Required
|
|
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
|
|
- HTTPS termination ready for production (replace domain and remove `tls internal`)
|
|
- Backup script ready for cron installation (copy to /etc/cron.d/)
|
|
- Caddy admin API exposed on localhost:2019 for future dynamic route management
