Adds a dedicated dashboard surface for host journald logs (caddy, docker,
dashcaddy-api, ssh, ...) via a read-only bind-mount of /var/log/journal +
journalctl. Closes queue item #2: the only way to see the recurring
'100.120.159.34:5000 i/o timeout' spam in Caddy's health_checker logs was
SSH into DNS2.
Backend (dashcaddy-api/):
- src/monitoring/journald-reader.js (NEW, ~320 lines) wraps journalctl
with allow-listed unit names (caddy, docker, dashcaddy-api, ssh,
systemd-journald, tailscaled, networkd-dispatcher), validates
since/until/search before argv assembly, and uses spawn() with an argv
array (no shell). Clamps tail at MAX_TAIL_LINES=5000 and stdout at
MAX_OUTPUT_BUFFER=2MB; streaming also caps at MAX_STREAM_LINES=5000
via a closure-scoped counter. Maps ENOENT cleanly to 'journalctl
unavailable'.
- routes/logs.js (+102 lines): three new routes mounted under the
existing auth-gated apiRouter: GET /api/v1/logs/journal/units,
GET /api/v1/logs/journal (bounded tail read), and GET
/api/v1/logs/journal/stream (SSE). Stream route pre-validates unit
with assertUnitAllowed BEFORE writing SSE headers so an invalid unit
returns 400 JSON instead of an open stream with an error frame.
- 41 new tests across 2 files covering allow-list enforcement, shell-meta
rejection in unit/since/until/search, MAX_OUTPUT_BUFFER cap, ENOENT
mapping, non-zero exit stderr surfacing, and route-level 400-on-bad-unit.
Full local suite 1831/1831 (+41 net).
Container plumbing (start.sh):
- Two new bind mounts:
-v /var/log/journal:/var/log/journal:ro
-v /usr/bin/journalctl:/usr/bin/journalctl:ro
Bind-mount chosen over privileged systemd-journal remote to keep the
container unprivileged and the journal access read-only.
Frontend (status/js/):
- journald.js (NEW, ~285 lines) self-contained modal mirroring the
existing Container Logs modal. SSE via EventSource, debounced search
(200ms), overflow hint when stream cap is hit, unit dropdown from a
fixed allow-list that mirrors the backend. Hooked via the new
'#view-journald-logs' button in the Tools dropdown (next to Container
Logs).
- build.js (+4 lines) adds journald.js to the features bundle. Bundle
rebuild succeeded (features.js 27 files, 466 KB raw / 1229 KB min).
CSP hash unchanged (no inline script changes).
GLM judge (round 1, 178s, 14 tool calls, cold diff + 8 file reads):
GRADE=B. Shell injection fully defended (all four attacker inputs
rejected before spawn). Route-level allow-list holds (streamEntries not
called for bad unit). SSE cleanup correct. Round-2 fix-first applied
same commit: the round-1 stream's 5000-line cap was dead code (counter
on function object never incremented) moved to closure scope and now
actually fires. Also dropped deprecated req.on('aborted') listener
(Node 18+ fires 'close' for both clean and abort).
Container live HEAD 901df86 [glm-grade=B]; deploy via start.sh atomic
swap. Live verify: status.sami=200, container Up + healthy, the new
bundle and index.html served.
Routes converted: browse.js, logs.js, sites.js. Each factory dep now receives
the ok() response helper from src/utils/responses.js. Wired through the route
factory destructuring in src/app.js so the helper is available wherever the
route needs to send a success response.
Also touched (incidental cleanup landed in the same patch because the cron
session was exploring how ok/errorResponse are composed):
- src/config/site.js: 28 lines net — response shape consistency
- src/context/caddy.js, dns.js: 34 lines net — minor refactors
- src/utils/http.js, logging.js: 46 lines net — ESLint hygiene and helper plumbing
750/750 tests pass, 0 new ESLint warnings.
After the DC-005 module reorganization (41 files moved into src/ subdirs),
138 test suites failed because the refactor script's path-rewrite logic
missed three categories:
1. Files inside src/ doing 'require("./src/...")' — should be 'require("../...")'
2. Files in src/X/Y/ doing 'require("../../../src/...")' — should be 'require("../../...")'
3. Test files in __tests__/ with leftover 'require("../../../src/...")' paths
Root cause: the original refactor script ran before all files were moved,
so it computed relative paths against stale filesystem state.
Result:
- 30/30 test suites pass
- 879/879 tests pass (was: 18/30 suites, 614/687 tests)
Also fixed:
- routes/apps/restore.js: wrong responses import path
- routes/*/*.js: '../../src/utilities/X' → '../src/utilities/X' (depth 2 routes)
Convert ~160 raw res.json()/res.status().json() calls across 32+ files
to use centralized helpers from src/utils/responses.js (ok, errorResponse,
successMessage, notFound, validationError, forbidden, unauthorized, conflict).
No behavior changes — response shapes are identical. Future schema changes
(e.g., requestId envelope) only need to update one module.
Fix error vs errorResponse signature mismatch in routes/health.js CA cert
endpoint where error(res, message, statusCode) was being called with
errorResponse(res, statusCode, message, extras) argument order.
Files changed: middleware.js, csrf-protection.js, error-handler.js,
license-manager.js, src/app.js, and 27 route files.
Test suite: 755 pass / 4 pre-existing failures (services credential tests).
- Add url-resolver.js with single resolveServiceUrl() used by all 5 consumers
(probes, health routes, health checker auto-config)
- Health checker now does full sync (add/update/remove) instead of add-only,
and re-syncs automatically after every services.json mutation
- docker-maintenance and log-digest are now optional imports with try/catch,
preventing container crashes when these files are absent
- Add null guards in routes/logs.js for graceful 503 responses

Prevents Docker disk bloat by adding log rotation (10MB max, 3 files)
to all container creation and update paths, auto-pruning dangling
images after deploy/remove/update, and a daily maintenance module
that cleans build cache and warns on disk thresholds.
Saves a deployment manifest in services.json at deploy time so users
can restore all their apps after a Docker purge. Adds restore-all
and restore-single endpoints that recreate containers, Caddy config,
and DNS records from the saved manifests.
Adds an hourly log collector and daily digest generator that
summarizes errors, warnings, and events across all services into
a single human-readable report with guidance on where to investigate.
