# Homelab Manager

Repository: `git@10.200.5.13:bobban/Homelab-manager.git` ([gitea.labsconnect.se/bobban/Homelab-manager](https://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](../Sloth%20manager)) and scheduled-task tracking
across Debian/Raspbian hosts (ported from
[Schedule Task Manager](../ScheduleTaskManager)). Looks and feels like a
[Tabler](https://tabler.io) 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.
- **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/`), 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](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.

**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; Docker bridge networks are left out; 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

```bash
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:

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

## 3. Run with Docker

```bash
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.
