Confirmed live: install_frigate()'s fresh-install path overwrote a working, hand-crafted docker-compose.yml (Frigate + mosquitto + frigate-notify) with zero backup, because that file's shape didn't match what frigate.sh's own "existing install" detection knew how to recognize. Every service's own detection is a judgment call about what counts as "already installed" and can miss a real setup built outside this repo's conventions. lib/common.sh gains backup_if_exists(FILE) — copies FILE to FILE.bak.<timestamp> if it exists, no-ops otherwise (including DRY_RUN). Applied before every service's own `cat > docker-compose.yml`/`cat > .env` write across all 60 services that do one (115 call sites), plus a matching standalone-mode stub added to every service's own bootstrap block, same convention already used for port_in_use/find_free_port. This doesn't replace a service's own update/fresh-reinstall detection — it's the safety net underneath it, so a wrong detection costs a .bak file to restore from instead of the original silently disappearing. Also fixes the actual gap that surfaced this: services/frigate.sh's Authelia offer only checked for Authelia installed locally on Frigate's own box, which is never true for a dedicated NVR box with no local Caddy either (the common shape — Caddy lives elsewhere, snippet-generation mode already handles that). Now offers Authelia protection unconditionally and, when Authelia isn't local, asks whether it lives on the same machine as Caddy (still "import authelia", since that's local to wherever Caddy ends up) or on a genuinely separate third machine (the explicit header-pinned forward_auth form, per CLAUDE.md's "forward_auth to a remote Authelia" note, needed because a bare authelia:9091 shortcut only works one hop).

# services/beszel.sh — Beszel lightweight server + Docker monitoring (hub + agent).
|
|
# Part of the modular post-install system (sourced by setup.sh).
|
|
#
|
|
# Can also be run standalone on any machine:
|
|
# sudo bash beszel.sh
|
|
# (Docker must already be installed when run standalone)
|
|
#
|
|
# Beszel is a hub+agent monitor: the hub is the web dashboard, the agent runs
|
|
# on each box you want metrics from and reports host resources (CPU, RAM,
|
|
# disk, network) plus per-container Docker stats — read directly off
|
|
# /var/run/docker.sock (mounted read-only), so it picks up whatever
|
|
# containers are currently running automatically. No per-container config;
|
|
# add/remove a service on this box and the agent just reports what it sees
|
|
# on its next poll.
|
|
#
|
|
# This installs both hub and agent on THIS box (the "same-system" layout —
|
|
# see supplemental/docker/same-system/docker-compose.yml in beszel's own
|
|
# repo, which this mirrors). The agent can also be pointed at additional
|
|
# remote boxes later; that's a from-the-hub-UI step, not something this
|
|
# installer sets up.
|
|
#
|
|
# Complements Gatus, doesn't replace it: Gatus is a black-box HTTP check —
|
|
# is the site actually responding, from the outside, like a visitor would
|
|
# see it. Beszel is white-box host/process monitoring — is the box itself
|
|
# under memory/disk pressure, is a specific container actually running vs.
|
|
# crash-looping. A container can be "Up" in Docker (Beszel sees it as
|
|
# healthy) while the app inside it is serving errors or hanging (only
|
|
# Gatus's actual HTTP probe would catch that) — they answer different
|
|
# questions, worth running both.
|
|
#
|
|
# Two-phase install, unavoidably: the hub generates its own SSH keypair and
|
|
# (once you enable it in Settings → Tokens & Fingerprints) a universal
|
|
# token, both only available after you've logged into the hub's web UI at
|
|
# least once — there's no way to generate or guess these ahead of time.
|
|
# This installer starts the hub first, waits for you to grab those two
|
|
# values, then wires up the agent. Re-run this installer later if you skip
|
|
# the agent step now — it'll pick up right where you left off instead of
|
|
# re-asking everything.

# Beszel — lightweight server + Docker monitoring
|
|
|
|
Hub (web dashboard) + agent (reports host and container stats), both on
|
|
this box. The agent reads `/var/run/docker.sock` (mounted read-only) to
|
|
report every currently-running container automatically — nothing to
|
|
configure per-service; install or remove a container on this box and the
|
|
agent's next poll just reflects it.
|
|
|
|
Also mounts the host's systemd/dbus sockets and sensor paths (read-only),
|
|
plus `security_opt: apparmor:unconfined` (required on Ubuntu/Debian for the
|
|
dbus connection to work at all — otherwise AppArmor silently blocks it), so
|
|
the hub's **Services** (systemd units) and **Temp** (hardware sensors)
|
|
columns work for this box — without both, a Docker-deployed agent silently
|
|
shows both empty, no error anywhere pointing at why (visible only at
|
|
`LOG_LEVEL=debug`).
|
|
|
|
## First login
|
|
|
|
No default account — open the hub and register the first user, which
|
|
becomes admin:
|
|
|
|
- URL: printed at the end of the install (Caddy domain if configured,
|
|
otherwise `http://localhost:<port>`)
|
|
|
|
## Connecting the agent (if you skipped it during install)
|
|
|
|
The agent needs the hub's public key and a universal token, both only
|
|
available after logging in:
|
|
|
|
1. Settings → Tokens & Fingerprints → enable the universal token, copy it
|
|
2. Copy the public key shown on the same page
|
|
3. Re-run `sudo ./setup.sh beszel` — it'll detect the agent isn't
|
|
connected yet and prompt for both values
|
|
|
|
## Monitoring additional boxes
|
|
|
|
Add another agent from the hub's UI ("Add System") to generate its
|
|
connection details, then on the OTHER box (a homelab machine, not this
|
|
VPS) run `sudo ./setup.sh beszel-agent` — a separate, agent-only install
|
|
(no hub, no web UI) built for exactly this. It connects OUTBOUND to this
|
|
hub over HTTPS, so no VPN, port-forwarding, or FQDN is needed for that box
|
|
— only this hub needs to be reachable, which it already is. See
|
|
`services/beszel.sh`'s `install_beszel-agent()`.
|
|
|
|
## Fronting this with Caddy
|
|
|
|
If you configured Caddy for Beszel, also update `APP_URL` in `.env` to
|
|
the real `https://` domain (it defaults to `http://localhost:<port>`,
|
|
which is what the hub uses for its own generated links and origin
|
|
checks) and restart:
|
|
|
|
```bash
|
|
docker compose restart beszel
|
|
```
|
|
|
|
## Manage
|
|
|
|
```bash
|
|
docker compose up -d
|
|
docker compose logs -f
|
|
docker compose pull && docker compose up -d
|
|
docker compose down
|
|
```

# Beszel agent (remote/homelab box)
|
|
|
|
Reports this box's host resources and Docker container stats to a Beszel
|
|
HUB running elsewhere — no hub, no web UI, nothing web-facing on this box
|
|
at all.
|
|
|
|
Also mounts the host's systemd/dbus sockets and sensor paths (read-only),
|
|
plus \`security_opt: apparmor:unconfined\` (required on Ubuntu/Debian for the
|
|
dbus connection to work at all — otherwise AppArmor silently blocks it), so
|
|
the hub's **Services** (systemd units) and **Temp** (hardware sensors)
|
|
columns work for this box too — without both, a Docker-deployed agent
|
|
silently shows both empty, no error anywhere pointing at why (visible only
|
|
at \`LOG_LEVEL=debug\`).
|
|
|
|
## Connecting (if you skipped it during install)
|
|
|
|
Same flow as the hub side, just on a different machine: log into the hub at
|
|
\`$HUB_URL\`, go to Settings → Tokens & Fingerprints, enable the universal
|
|
token, and paste whatever it gives you (the "copy for docker compose"
|
|
shortcut works fine) by re-running:
|
|
|
|
\`\`\`bash
|
|
sudo ./setup.sh beszel-agent
|
|
\`\`\`
|
|
|
|
## Why no VPN or port-forwarding
|
|
|
|
This agent connects OUTBOUND to the hub over HTTPS/WebSocket using the key
|
|
and token above — nothing on this box ever needs to be reached FROM the
|
|
hub, so there's no inbound port to open, no router port-forward, no VPN
|
|
tunnel, and no FQDN needed for this box itself. Only the hub needs to
|
|
already be reachable at the URL you gave it.
