The pack./packwiz service was removed operationally long ago, but several plan docs still presented pack. as a live caddy vhost / DNS subdomain and render-pack.sh as a current tool. Remove those references from the current-architecture docs (overview, caddy, tooling, uptime-kuma, letsencrypt, mc-backup); leave the migration log (04-mods.md), superseded banner (04-packwiz.md), commit history (12-build-order.md), and planned landing rework (18) intact as deliberate history.

# 10 — Uptime Kuma
|
|
|
|
> Distinct from **`plan/15-mc-status.md`**: Kuma is the uptime *history* +
|
|
> alerting backend; mc-status is the live data feed for the landing's server
|
|
> card. Both ping `minecraft` over `mcnet` but serve different purposes.
|
|
|
|
Status monitoring + public status page. Service `uptime-kuma`
|
|
(`louislam/uptime-kuma:1`), web UI on `:3001`, reached only through caddy at
|
|
`https://status.${BASE_DOMAIN}`. Joined to `mcnet`, so it can probe every other
|
|
service by its internal container name.
|
|
|
|
## Add a Minecraft monitor
|
|
|
|
Uptime Kuma 1.x ships a built-in **Minecraft Server** monitor type. It uses the
|
|
Server List Ping protocol (the same ping the vanilla multiplayer list uses):
|
|
unauthenticated, so it works fine with `ONLINE_MODE=FALSE` /
|
|
`ENFORCE_SECURE_PROFILE=FALSE`. It reports latency, online/max players, and MOTD.
|
|
|
|
1. Open `https://status.${BASE_DOMAIN}` and log in (admin account created on
|
|
first run).
|
|
2. **+ Add New Monitor**.
|
|
3. **Monitor Type**: `Minecraft Server`.
|
|
4. Fill in one of the two probe targets below.
|
|
5. **Heartbeat Interval**: `60` s (fine for a friends' server).
|
|
6. **Retries**: `2`, **Retry Interval**: `30` s — avoids flapping on a GC pause.
|
|
7. **Save**.
|
|
|
|
### Two targets — add both
|
|
|
|
| Monitor | Server | Port | What it proves |
|
|
|---|---|---|---|
|
|
| `MC (internal)` | `minecraft` | `25565` | The server process is up and accepting pings inside `mcnet`. |
|
|
| `MC (public)` | `mc.${BASE_DOMAIN}` | `25565` | The full path works: DNS → host firewall → docker port publish → server. |
|
|
|
|
The **public** monitor is the one that catches "I can't connect" outages —
|
|
firewall, DNS, or an unpublished port all show red here while the internal
|
|
monitor stays green. Run both to tell *server down* apart from *path broken*.
|
|
|
|
> Internal `minecraft` resolves because uptime-kuma is on `mcnet` (the container
|
|
> name is the hostname). It is **not** routed through caddy — caddy only fronts
|
|
> HTTP vhosts, and MC is raw TCP. Do not point the monitor at `caddy` or any
|
|
> `status.` alias.
|
|
|
|
## Notes
|
|
|
|
- The Minecraft monitor pings TCP `25565`; it does **not** check Simple Voice
|
|
Chat (`24454/udp`). Add a separate **TCP Port** monitor against UDP if you want
|
|
voice coverage — but Kuma's TCP monitor is TCP-only, so UDP voice has no clean
|
|
probe; rely on the player report instead.
|
|
- Put both MC monitors on the public **status page**
|
|
(Settings → Status Pages) so guests can self-check before pinging you.
|
|
- Optional companion HTTP monitors for the web stack:
|
|
`https://auth.${BASE_DOMAIN}`, `https://distribution.${BASE_DOMAIN}`,
|
|
`https://${BASE_DOMAIN}` — a red `distribution.` here explains client
|
|
mod-mismatch join failures.
