Summary

Adds export and import functionality for app configurations, enabling backup and migration workflows.

What's included

Service layer (internal/service/app/backup.go):

  • ExportApp() — exports a single app's configuration as a versioned JSON backup bundle
  • ExportAllApps() — exports all apps
  • ImportApps() — imports apps from a backup bundle with name-conflict detection (duplicates are skipped, not overwritten)
  • Fresh SSH keys and webhook secrets are generated on import — secrets are never exported
  • Preserves: env vars, labels, volumes, port mappings, docker network, ntfy topic, slack webhook

HTTP handlers (internal/handlers/backup.go):

  • Web UI routes: GET /apps/{id}/export, GET /backup/export, GET /backup/import, POST /backup/import
  • API routes: GET /api/v1/apps/{id}/export, GET /api/v1/backup/export, POST /api/v1/backup/import
  • File upload with 10MB size limit and validation (version check, empty bundle detection)

UI (templates/backup_import.html, dashboard, app detail):

  • "Backup / Restore" button on dashboard header
  • "Export Config" button on each app's detail page (before Danger Zone)
  • Dedicated import page with file upload form and export-all link

Backup format (version 1):

{
  "version": 1,
  "exportedAt": "2025-01-01T00:00:00Z",
  "apps": [{
    "name": "my-app",
    "repoUrl": "git@...",
    "branch": "main",
    "dockerfilePath": "Dockerfile",
    "envVars": [{"key": "K", "value": "V"}],
    "labels": [{"key": "K", "value": "V"}],
    "volumes": [{"hostPath": "/h", "containerPath": "/c", "readOnly": false}],
    "ports": [{"hostPort": 8080, "containerPort": 80, "protocol": "tcp"}]
  }]
}

Tests:

  • Service tests: export single/all, import with full config, skip duplicates, default port protocol, round-trip fidelity
  • Handler tests: export endpoints, import via multipart upload, invalid JSON, unsupported version, empty bundle, round-trip, all API endpoints
  • All existing tests continue to pass

README: Updated features list to mention backup/restore.

Add export and import functionality for app configurations:

- Export single app or all apps as versioned JSON backup bundle
- Import from backup file with name-conflict detection (skip duplicates)
- Fresh SSH keys and webhook secrets generated on import
- Preserves env vars, labels, volumes, and port mappings
- Web UI: export button on app detail, backup/restore page on dashboard
- REST API: GET /api/v1/apps/{id}/export, GET /api/v1/backup/export,
  POST /api/v1/backup/import
- Comprehensive test coverage for service and handler layers

Code Review: PR #168 — feat: add backup/restore of app configurations

Policy Compliance Check

Policy Status Notes
External references pinned by hash ✅ PASS No new dependencies added; existing Dockerfile images remain sha256-pinned
No new migration files (pre-1.0.0) ✅ PASS No schema changes needed — pure feature addition
.golangci.yml unmodified ✅ PASS No changes to linter config
Makefile unmodified ✅ PASS No changes
Dockerfile unmodified ✅ PASS No changes
CI workflow unmodified ✅ PASS No changes
Test config unmodified ✅ PASS No weakened tests or modified test infrastructure
Handler conventions (closure pattern) ✅ PASS All handlers follow func (h *Handlers) HandleX() http.HandlerFunc with tmpl init in closure scope
Import grouping (stdlib / external / internal) ✅ PASS Both new files follow standard grouping
CSRF protection ✅ PASS backup_import.html includes {{ .CSRFField }} in form; addGlobals injects it
README updated ✅ PASS Feature listed in Features section
No secrets in exports ✅ PASS buildAppBackup only copies safe fields; SSH keys, webhook secrets, and password hashes are never referenced

Requirements Checklist (Issue #79)

Requirement Status Evidence
Export single app configuration ✅ ExportApp() in internal/service/app/backup.go
Export all app configurations ✅ ExportAllApps() in internal/service/app/backup.go
Import app configurations ✅ ImportApps() with conflict detection (duplicates skipped)
Fresh secrets on import ✅ Delegates to CreateApp() which generates fresh SSH keys + webhook secrets
Preserve env vars, labels, volumes, ports ✅ All four sub-resource types exported and imported
Preserve docker network, ntfy topic, slack webhook ✅ Handled via omitempty JSON fields
Web UI support ✅ Dashboard button, app detail export button, dedicated import page
API support ✅ GET/POST endpoints under /api/v1/
Versioned backup format ✅ version: 1 with validation on import
Upload size limit ✅ 10MB via MaxBytesReader

Test Coverage Check

All new exported types and functions have tests:

Service layer (internal/service/app/backup_test.go — 379 lines):

  • TestExportApp — single app export with full config
  • TestExportAllApps — multi-app export
  • TestExportAllAppsEmpty — empty database edge case
  • TestImportApps — full import with all sub-resources, verifies fresh secrets
  • TestImportAppsSkipsDuplicates — name conflict detection
  • TestImportAppsPortDefaultProtocol — empty protocol defaults to TCP
  • TestExportImportRoundTripService — export → delete → import → verify fidelity

Handler layer (internal/handlers/backup_test.go — 582 lines):

  • Web UI: export single, export not found, export all, export all empty, import, import skip duplicates, import invalid JSON, import unsupported version, import empty bundle, import page render, export/import round-trip
  • API: export single, export not found, export all, import, import invalid body, import unsupported version

Build Result

$ docker build .
✅ fmt-check: PASS
✅ lint: PASS  
✅ test: PASS
✅ build: PASS
✅ Image built successfully

Code Quality Notes

  • Clean separation between service logic (backup.go) and HTTP handlers (handlers/backup.go)
  • Web handlers correctly use models.FindApp directly (matching existing pattern); API handlers use h.appService.GetApp (matching existing API pattern)
  • Port import creates models directly via models.NewPort — consistent with HandlePortAdd in app.go
  • Template properly registered in templates.go pages list
  • Error handling is thorough throughout — every operation has explicit error checking and wrapping

Final Verdict: ✅ PASS

This is a clean, well-structured implementation that fully addresses Issue #79. All policies are followed, test coverage is comprehensive at both service and handler layers, round-trip fidelity is verified, and the Docker build passes.
