Homelab Manager

Repository: git@10.200.5.13:bobban/Homelab-manager.git (gitea.labsconnect.se/bobban/Homelab-manager externally).

A single dashboard for a homelab: Proxmox, Synology DSM, Semaphore, Tailscale, Gitea, and Dockhand/Docker status and basic actions, plus DNS record management, an IP address inventory (IPAM), and a secret-expiry tracker (ported from Sloth Manager) and scheduled-task tracking across Debian/Raspbian hosts (ported from Schedule Task Manager). Looks and feels like a Tabler admin dashboard. Sign-in is delegated to Authentik (OIDC), with local admin/operator/viewer roles.

Status

All modules from the original plan are built:

• Monorepo scaffold, Tabler-themed app shell/navigation

• Authentik OIDC login, roles (first user to sign in becomes admin), audit log

• Dashboard — an overview of every system this app tracks, all sharing one widget-card design (label + status badge, a small stat row, then its own breakdown): DNS (domain/record counts per provider, cached records by type), Secrets (monitored/expiring/expired, by type), and one widget per integration — Tailscale by OS, Proxmox by node (VM/LXC counts too), Dockhand by container state (plus host count), Semaphore and Gitea by last-run status (plus private-repo count), and Synology's CPU/RAM alongside its disk-health breakdown. Breakdowns render as a stacked proportion bar with a legend — no charting library, matching the rest of the app's plain-Tabler-CSS approach. The Servers widget shows how many servers are online, offline, or have never reported, which are offline and for how long, and any disk at or above the usage threshold — decided by the same rules as the health alerts, so the widget and the notifications always agree, and following the thresholds in Settings even for viewers who can't open them. The Domains widget shows how many registrations are tracked, which are expired or expiring (soonest first), the next one to expire, and how many couldn't be refreshed.

• Diagnostic Log (admin-only) — every call this app makes to a DNS provider or integration (Tailscale, Proxmox, Synology, Semaphore, Gitea, Dockhand), success or failure, with latency and the error message if it failed — the last 500 calls, filterable by source/result, for troubleshooting connectivity issues (ported from Sloth Manager's provider-diagnostics log, generalized to cover every integration this app has, not just DNS)

• Secrets — expiry tracking for API tokens/certs/passwords. An SSL certificate can optionally be given a host:port to watch: the app opens a real TLS connection (daily, and on demand via "Check now"), reads the certificate's actual expiry, and keeps the date current — so a renewed cert is picked up automatically and an unreachable host is flagged instead of silently going stale

• IP Addresses (IPAM) — inventory of IPs across vendors/locations, with "Sync from Tailscale" and "Sync from Proxmox" actions to pull in tailnet device IPs and VM/LXC IPs (never overwrites a manually-entered IP), and each entry now shows its matching DNS record(s) from the DNS module's cache

• DNS — zone/record management across Cloudflare, Loopia, Pi-hole, Azure DNS, cPanel, and Technitium; providers are configured in-app (not via env vars) and their credentials are encrypted at rest

• Servers — cron/systemd tracking across Debian/Raspbian servers via a lightweight push agent (agent/linux/), Windows scheduled-task tracking through a PowerShell agent (agent/windows/, see its README), plus manual entries for things an agent can't see (Docker jobs, backups). The Servers page itself just lists registered servers and (admin-only) adds new ones / issues agent tokens; clicking a server opens its detail page with CPU/RAM/disk status, IP addresses, matching DNS names (looked up from the DNS module's cache), and its scheduled tasks — live hardware from Proxmox for VM/LXC-backed servers, or from the agent's own hardware report for everything else, both showing the same per-disk usage breakdown (an LXC's root filesystem read straight from the host; a QEMU VM's actual mounts via its guest agent, alongside the allocated size Proxmox already knew about without one). Proxmox-linked servers also get start/stop/restart buttons right on the detail page. The detail page also has an Admin Links section (operator/admin to add/edit/remove) for bookmarking that server's own admin UIs — Dockge, Webmin, Cockpit, Portainer, or anything else reachable by URL. Since not every server is a Proxmox VM, an admin can hide the "Proxmox link" card per server ("Not a VM? Hide this" / "+ Show Proxmox link options") — it stays visible regardless once a server actually is linked, so unlinking is always reachable.

• Tailscale, Proxmox, Synology, Semaphore, Gitea, and Docker each get their own top-level page (backed by the matching integration) instead of living inside a shared Integrations browsing view:

  • Tailscale — device list with online/authorized status, and authorize/deauthorize/remove actions; a live device-count widget.
  • Proxmox — VM/LXC status across every node in the cluster, with start/restart/shutdown/stop actions; a live running/total widget. Each online node also gets its own host-stats card — uptime, CPU usage/cores/ load average, RAM and swap usage, and per-storage usage (local, LVM-thin, ZFS, NFS, etc). Supports self-signed certificates (common in homelab setups).
  • Synology — volume and disk health (read-only by design). Supports self-signed certificates.
  • Semaphore — Ansible run status per template across every project, with a "Run" action to trigger a template; a live template-count widget (with a last-failed warning).
  • Gitea — repo list with each repo's last CI run status, and re-running just the failed jobs in a run; a live repo-count widget (with a failing-build warning).
  • Docker — container status across every Docker host Dockhand manages (one credential covers all of them), with start/stop/restart actions, a host filter, image-update status per container (from Dockhand's own cached update check, plus a button to trigger a fresh one), and a live running/total widget (with an updates-available count).

  The Integrations page itself is now just a list of configured integrations (name/type/status, visible to every role) with an admin-only "Add integration" button and edit/enable/disable/delete actions per row — the six dedicated pages above are where you actually use each one.

• Every table in the app is click-to-sort on any column (numbers, booleans, and dates/text sort correctly regardless of how the column formats them) and has an "Export CSV" button next to it that exports whatever's currently sorted/filtered. Tables that can realistically grow large (DNS zones/records, IP Addresses, Secrets, Servers, Audit Log, and each integration's device/container/guest/repo/template list) are paginated, 20 rows per page by default — adjustable under Settings → Display — and CSV export still covers every sorted/filtered row, not just the current page.

• Settings (admin-only) — notification channels (Gotify, ntfy, SMTP, generic webhook) with per-channel test buttons, per-event toggles (DNS record added/updated/deleted, daily secret-expiry reminder and daily Tailscale key-expiry reminder — both sharing one configurable time/timezone), badge-color customization for both DNS providers and integration types, and a Display tab (date order, 12/24-hour clock, and rows-per-page for every paginated table) applied consistently across the app.

All six integrations follow the same config-in-UI + encrypted-credentials pattern, added (and edited — e.g. to rotate an expired API token without recreating the whole integration) through Integrations → Manage integrations. See INTEGRATIONS.md for exactly what credential to create and what access it needs in each target system, for every integration and DNS provider.

Verified for real, end to end: every module above — including all six integrations, both their read-only views and their write actions (start/stop/restart, trigger-a-run, authorize/deauthorize) — has been exercised against the user's actual live homelab, not just built against specs. That pass also found and fixed two real bugs: the Synology adapter assumed HTTPS-only (the NAS is reached over plain HTTP), and the Tailscale adapter read online/isExitNode fields that don't actually exist in the real API response (fixed to derive them from connectedToControl and enabledRoutes). See the git log for the full verification notes per integration.

Server and storage health is watched every 15 minutes: a server whose agent stops reporting, a server disk / Proxmox storage / Synology volume passing a usage threshold, and a Synology volume or disk that's degraded or failing each raise one notification when the problem starts and one when it clears (both thresholds are set under Settings → Notifications). Active problems are remembered across restarts, so a rebuild doesn't re-alert them.

Tags — servers can be tagged (prod, media, rack-1, …) from their detail page by operators and admins. Tags show as coloured chips on the Servers page, which can be filtered by one or several tags (the filter is in the URL, so a tag on a server's page links to everything sharing it), and they're searchable from the global search box. Admins manage tags under Settings → Tags: add tags before any server uses them (they're offered as one-click suggestions when tagging), give any tag a colour of your choosing (or leave it on the automatic one), rename tags, and delete them. Renaming to a name that already exists merges the two, and both rename and delete rewrite every server that carries the tag.

Privacy — a page every signed-in user can open that says what this installation stores (accounts, sign-in sessions with their IP and browser, the audit and diagnostic logs, server reports, the secrets tracker, credentials), where data goes (Authentik, your integrations and DNS providers, the notification channels that are switched on, domain registries), what's kept in the browser, who can see what, and how to limit or remove data. Retention, integrations and channels are read live from the installation; channel addresses are shown to admins only. Each user sees their own account and sign-ins there and can download their own data (account, sign-ins, audit-log entries) as a JSON file.

Consistency — a report of where IPAM, DNS and your servers disagree about an address: the same address on two servers, a DNS record named after a server that points somewhere it isn't, an IPAM entry labelled with a server's name at the wrong address, addresses in use that IPAM doesn't list (with an "Add to IPAM" button), and server addresses no DNS record points at. It only compares data the app already holds — nothing is fetched when you open it — so it says how many servers reported addresses and how fresh the synced DNS zones are. Only private addresses are compared; ranges you exclude (Docker's, which repeat the same subnet on many hosts — 172.16.0.0/12 is excluded by default, remove it if that's a real LAN for you) are left out of every source; anything that's fine on purpose can be ignored with a reason, and stays ignored.

Domains — when each domain registration expires, read from the registry itself. The domains behind your DNS zones are picked up automatically (a zone like lab.example.se resolves to the example.se registration that actually expires); others can be added by hand. Each is looked up daily over RDAP where the TLD offers it, and otherwise over WHOIS via IANA's referral — which is what makes .se, .nu and .io work, since those aren't in the RDAP bootstrap. You're reminded daily from N days before expiry (Settings → Notifications, default 30) until it's renewed, and told when an expiry date couldn't be refreshed for several days. Registries that don't publish an expiry (.de, .eu) can be tracked but have no date to warn about. Private zones (.lan, .local) are skipped.

Automation failures — every 15 minutes the app looks at the latest run of each Semaphore template and each Gitea repo's latest workflow run. A failed one raises a single notification (with the project/template or repo, run number, and for Gitea the run's link), and another when a later run succeeds. It's state-based, so a job that fails every night alerts on the first failure rather than every night. A run that's still going, was cancelled, or was stopped by hand leaves things as they were, and anything that couldn't be read (a Semaphore project or Gitea repo that errored, or an integration that's down) is neither cleared nor re-announced. The first check after upgrading only records what's already failing, so old failures aren't announced. Toggle it under Settings → Notifications. For Gitea this follows the repo's most recent run on any workflow or branch, the same as the Gitea page shows.

Maintenance mode silences alerts about one server, integration, or DNS provider while you work on it (server offline / disk, storage and Synology health, Proxmox backup alerts, and "integration down" for that service type). Every window has a fixed end (5 minutes to 7 days) and expires on its own, and a problem that began during a window and is still present when it ends alerts then — a forgotten window can't hide an outage. A banner shows what's currently silenced to every signed-in user.

Ports — each server's detail page has a Ports card for finding free ports and remembering what each one is for. "Scan…" runs a TCP scan of a port range from the app against the server's address (private addresses only, up to 20,000 ports at a time) and lists what's open plus the ranges that were confirmed free; a free range can be clicked to reserve a port. Any port can carry a service name and a comment, and a port with a note counts as taken even when nothing is listening. The agent also reports what is bound on the host (ss), which catches services listening on localhost only — a scan from elsewhere can't see those, so they'd otherwise look free. Re-run the agent install one-liner on a host to pick that up.

The app is installable as a PWA — "Install app" / "Add to Home Screen" from the browser gives it its own icon and a standalone window on phone or desktop. This needs the site to be served over HTTPS (browsers only offer install on secure origins; localhost also counts). The bundled service worker deliberately caches nothing, so an installed copy always shows the current build.

Requirements

• Node.js 20+
• An Authentik instance reachable from wherever this app runs

1. Set up an Authentik application

1. Create an OAuth2/OpenID Provider:
   • Redirect URI: <APP_BASE_URL>/auth/callback
   • Scopes: openid, email, profile
2. Create an Application using that provider, and assign the users/groups who should be able to sign in — Authentik controls who can authenticate; the app's own admin/operator/viewer roles control what they can do once in.
3. Copy the provider's issuer URL, client ID, and client secret into .env.

2. Local development

cp .env.example .env   # fill in AUTHENTIK_*, SESSION_SECRET, CREDENTIALS_ENCRYPTION_KEY
npm install
npm run dev:server   # http://localhost:3000 (API)
npm run dev:web      # http://localhost:5173 (Vite dev server, proxies /api and /auth to :3000)

Visit http://localhost:5173 during development. Database migrations run automatically on server start. SQLite data lands in ./data (gitignored).

Generate SESSION_SECRET and CREDENTIALS_ENCRYPTION_KEY with:

node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"

3. Run with Docker

cp .env.example .env
# edit .env
docker compose -f docker-compose.dev.yml up -d --build   # build locally
# or, once an image is published to your registry:
docker compose up -d

The app listens on HOST_PORT (default 3000); SQLite data persists in ./data on the host.

arm64 (Raspberry Pi, Apple silicon, ARM servers)

Two compose files, one to build the image and one to run the published one:

# On any machine with Docker: build the arm64 image and push it to the registry
docker compose -f docker-compose.arm64.build.yml build
docker compose -f docker-compose.arm64.build.yml push

# On the arm64 machine: pull that image and run it (no build there)
docker compose -f docker-compose.arm64.yml pull
docker compose -f docker-compose.arm64.yml up -d

docker-compose.arm64.build.yml can also build and run right on an arm64 machine (up -d --build). Building on x86 goes through QEMU emulation — slower, and it needs a one-time docker run --privileged --rm tonistiigi/binfmt --install arm64.

Both files use the image gitea.labsconnect.se/bobban/homelabmanager-homelab-manager:arm64. Set IMAGE_REPO and/or ARM64_TAG in .env to use another registry or to pin a release tag (e.g. ARM64_TAG=1.4.0-arm64). The arm64 tag is kept separate from the default image, so the existing docker-compose.yml is unaffected. A .dockerignore keeps host node_modules, .env and data/ out of the build.
