jackos1998 d51f2d62b6 docs: Document the deployment
Add a top-level README mapping the boxes and a full docs/ tree: topic
pages (architecture, networking, deployment), per-site box pages for
colony and home with containers nested under their hosts, remote and
mobile boxes, the installer, and the home switch fabric reference
(folded in from home-switches.md, with AGENTS.md and code comments
retargeted to its new home). Box pages carry marked assignment tables
that CI regenerates from nixos.allAssignments.

AGENTS.md points at the new docs and keeps its terse agent version of
the mechanics, referring to the topic pages for depth.

# kelder-spoder
The web container for the kelder site: Nextcloud plus an nginx (OpenResty) reverse proxy for
the site's services.
- **Source:** [`nixos/boxes/kelder/containers/spoder/`](../../nixos/boxes/kelder/containers/spoder)
- **Host:** NixOS container on [`kelder`](kelder.md)
## Role
- **Nextcloud** (`nextcloud32`) at `cloud.hentai.engineer` (trusted alias
`cloud-local.hentai.engineer`), SQLite backend, data in `/mnt/storage/nextcloud`
(`/mnt/storage` is bind-mounted from the host).
- **nginx reverse proxy** (`openresty`) terminating TLS for the site's public vhosts, with a
wildcard ACME cert for `hentai.engineer` via Cloudflare DNS. The kelder host forwards
`http`/`https` to this container; uploads are unlimited (`clientMaxBodySize = 0`) for
Nextcloud's sake.
## Network assignments
<!-- assignments: kelder-spoder -->
<!-- assignments-start -->
| Name | Assignment | IPv4 | IPv6 | Domain | Notes |
|---|---|---|---|---|---|
| spoder-ctr | internal | `172.16.64.3/24 gw 172.16.64.1` | — | hentai.engineer | |
<!-- assignments-end -->
## Proxy vhosts
All under `hentai.engineer`, each with a `*-local` alias:
| vhost | Target | Auth |
| --- | --- | --- |
| `monitor` | `netdata` on the kelder host (:19999) | `htpasswd` |
| `kontent` | Jellyfin on `kelder-acquisition` (:8096, incl. websocket) | — |
| `torrents` | Transmission on `kelder-acquisition` (:9091) | `htpasswd` |
| `jackett` | Jackett on `kelder-acquisition` (:9117) | `htpasswd` |
| `radarr` | Radarr on `kelder-acquisition` (:7878) | `htpasswd` |
| `sonarr` | Sonarr on `kelder-acquisition` (:8989) | `htpasswd` |
| `cloud` | Nextcloud (local) | — |
An `init_worker_by_lua` timer polls `v4.ident.me` every 5 minutes to track the site's public
IP; it feeds `localRedirect` rewrites (bounce public-IP clients to the `*-local` name) that
are currently **disabled** (commented out — Virgin Media filters DNS answers containing local
IPs, so the split doesn't work as intended).
## Networking
- `internal` assignment (name `spoder-ctr`) on the host's `ctrs` bridge, MTU 1420.
## Notable config files
- [`nixos/boxes/kelder/containers/spoder/default.nix`](../../nixos/boxes/kelder/containers/spoder/default.nix) — Nextcloud + ACME.
- [`nixos/boxes/kelder/containers/spoder/nginx.nix`](../../nixos/boxes/kelder/containers/spoder/nginx.nix) — reverse proxy vhosts.
