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
