# 106 — `auth-outpost`
|
|
|
|
Authentik **forward-auth outpost** for LAN-gated apps. A stateless proxy that connects outbound to the [VPS Authentik core](../investigations/2026-05-31-authentik-vps-migration.md) and serves forward-auth locally, so [Caddy (121)](121-caddy.md) never hairpins auth through VPS Traefik.
|
|
|
|
## At a glance
|
|
- **Hostname:** `auth-outpost`
|
|
- **IP:** `192.168.8.6` (static)
|
|
- **Privilege:** privileged (Docker-in-LXC, `features: nesting=1`)
|
|
- **Resources:** 1 core / 512 MiB / 4 GiB rootfs
|
|
- **Mounts:** none
|
|
- **Created:** 2026-06-01, Debian 13, replacing the embedded outpost on [124](124-authentik.md)
|
|
|
|
## Role
|
|
|
|
Runs one container — `ghcr.io/goauthentik/proxy` — that opens an outbound websocket to `https://auth.hubris.network` (the VPS core), pulls its proxy-provider config, and answers Caddy's `forward_auth` subrequests on `192.168.8.6:9000` (LAN-only bind). Because the call path is **Caddy → outpost (LAN)**, with no Traefik in between, `X-Forwarded-Host` is preserved — the failure that 404s when Caddy is pointed at `https://auth.hubris.network` directly (Traefik rewrites the header). See the [migration investigation](../investigations/2026-05-31-authentik-vps-migration.md).

## Config paths
|
|
- `/opt/authentik-outpost/docker-compose.yml` — `ghcr.io/goauthentik/proxy:2026.5.2`, `AUTHENTIK_HOST=https://auth.hubris.network`, `AUTHENTIK_INSECURE=false`, port bound `192.168.8.6:9000`.
|
|
- `/opt/authentik-outpost/.env` (mode 600, **untracked**) — `AUTHENTIK_TOKEN` for outpost `hubris-lan-outpost` (sops-encrypt into `secrets/` — TODO Phase 5).
|
|
|
|
## The outpost object (VPS Authentik)
|
|
- Outpost **`hubris-lan-outpost`** (type proxy), providers: `hubris-forward-auth` (domain, Paperless + domain-level apps), `Provider for Torrent` (qBittorrent), `Provider for Artifacto` (single).
|
|
- Health: VPS admin → Applications → Outposts → last-seen current; `curl http://192.168.8.6:9000/outpost.goauthentik.io/ping` → `204`; container log `Successfully connected websocket`.
|
|
|
|
## Caddy wiring
|
|
[Caddy (121)](121-caddy.md) `(authentik)` snippet `reverse_proxy`/`forward_auth` → `http://192.168.8.6:9000` (was `192.168.8.180:9000` on LXC 124). Tracked in `dtoro/caddy-conf`.

## Changelog
|
|
|
|
### 2026-06-01 — created; forward-auth cut over from LXC 124
|
|
New dedicated LXC for the LAN forward-auth outpost (Phase 1 of the [architecture migration](../investigations/2026-05-31-authentik-vps-migration.md)). Deployed `goauthentik/proxy:2026.5.2` pointed at the VPS core; repointed Caddy `(authentik)` from `192.168.8.180:9000` → `192.168.8.6:9000`. Verified Paperless/qBittorrent/Artifacto return the SSO redirect with **124-Authentik stopped**, confirming the frozen instance is out of the path. dnsmasq stays on 124 until [DNS is relocated](124-authentik.md).
