Multiple modules derived file paths from __dirname, which is unstable in two
ways: (1) it moves whenever the file is reorganized under src/, and (2) it
points to the in-container source dir /app/src/<x> in production, which is
not bind-mounted, so writes would silently land in the image layer.
Affected modules (10 files): backup-manager, resource-monitor, update-manager,
docker-security, audit-logger, bundled-workflows, port-lock-manager, logging,
error-handler, license-keygen, plus crypto-utils and credential-manager which
already had multi-candidate resolvers but no centralised fallback.
Introduced platformPaths.dataDir (derived from SERVICES_FILE/CONFIG_FILE/
DNS_CREDENTIALS_FILE env vars when set, else path.dirname(servicesFile)) so
every module resolves the same canonical data directory. Each module now
fans the runtime files into the data dir while preserving per-file env-var
overrides for custom deployments.
Why a single resolver:
- one place to swap the default path scheme in v2.x without chasing
hardcoded __dirname joins
- a single source-of-truth for tests, backup tools, and the soon-to-be
added single-volume migration script
- prevents the class of DC-033 (self-updater 0.0.0) bugs where __dirname
drift in a subdirectory silently loses runtime state
Also fixed:
- audit-logger: AUDIT_LOG_FILE default was /app/src/security/audit-log.json
(writable in dev, image-layer in production). Now /app/data/audit-log.json
via platformPaths.dataDir, matching logging.js's same file. Same physical
path, no behavior change for callers that already set AUDIT_LOG_FILE.
- logging.js: LOG_DIR was __dirname (src/utils/) — error.log and
audit-log.json were being written into the source tree. Now
platformPaths.dataDir, matching every other persistent file.
- error-handler.js: ERROR_LOG_FILE hard-coded to __dirname/error.log
(src/utilities/error.log), redundant with logging.js's own default.
Now platformPaths.dataDir/error.log.
- host-registry / event-store / event-workers: simplified the
'platformPaths.dataDir || path.join(__dirname, ../../data)' pattern
to just platformPaths.dataDir (the legacy fallback is no longer
reachable — services.json lives at dataDir/services.json now).
- public-routes-drift.test.js: added 'routes/security.js' to the
direct-mount list so the /api/v1/security/events/ingest and
/api/v1/security/events/batch entries in PUBLIC_ROUTES are
recognized as mounted (was missing — fixed DC-044's drift-detection
test gap).
Tests: 1214/1214 pass (0 new failures, 1 new test for the corrected route
mount detection path). ESLint: 146 warnings + 4 errors — same baseline as
HEAD (no new warnings or errors introduced; one pre-existing require-await
on readline was removed as a drive-by in event-workers.js since the module
uses line-level fs reads, not readline). Container config files like
audit-log.json, container-stats.json, and workflow-history.json still
exist on the running container's image layer — Docker will pick up the
new defaults on the next recreate (the update path already moves
services.json+config.json+credentials.json via the data bind mount).
Cross-platform hardening — removes all hardcoded /app/ paths from route files
and routes them through platform-paths.js so the app works the same way
regardless of Docker layout (single-file mount vs consolidated data dir).
Changes:
- platform-paths.js: add generatedCertsDir, pkiDir, containerUpdatesDir,
containerFrontendDir, containerAssetsDir, resolveAssetsPath()
- self-updater.js: UPDATE_URL/MIRROR_URL/CHANNEL env var overrides
- routes/ca.js: use platformPaths for cert paths and generated certs dir
- routes/services.js: use platformPaths.pkiRootCert
- routes/themes.js: derive THEMES_DIR from platformPaths.servicesFile
- routes/config/assets.js + backup.js: use resolveAssetsPath() fallback
- routes/services.js + src/app.js: use platformPaths.pkiRootCert
- server.js: HOST env var support, parse PORT as int
- src/app.js: GET /api/v1/version (public, no auth), global request timeout,
disable x-powered-by, trust proxy
- pylon/dashcaddy-pylon.js: PYLON_HOST env var, graceful shutdown on SIGTERM/SIGINT
A fresh user can now deploy with a custom Docker layout (e.g. /opt/dc/data/
as a single volume mount) and the app finds its files automatically, no env
var configuration required.
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.
