Deploy Fly.io Proxy / deploy (push) Successful in 1m12s
## Summary Brings up the Adelaide / Heidi / Addie baby shower app on ringtail k3s with the public/private split that the app's hosting contract calls for: `shower.eblu.me` (public, via Fly proxy) and `shower.ops.eblu.me` (tailnet). App is consumed as a wheel from the Forgejo PyPI index — source lives at [`adelaide-baby-shower-app`](https://forge.eblu.me/eblume/adelaide-baby-shower-app). ### What's included - **ArgoCD app + manifests** under `argocd/manifests/shower/` (deployment, service, ProxyGroup ingress, ConfigMap for `DJANGO_DEBUG`/`DJANGO_ADMIN_URL`, ExternalSecret for `DJANGO_SECRET_KEY` from 1Password item `Shower (blumeops)`, NFS PV on sifaka, RWX media PVC, RWO local-path data PVC for SQLite). Recreate rollout because SQLite is single-writer. - **Public surface** (`fly/`): new `shower.eblu.me` server block proxying to `shower.ops.eblu.me`. `/admin/` returns 403 at the edge except `/admin/login/` and `/admin/logout/`, which are rate-limited via a new `shower_auth` zone. `X-Clacks-Overhead` on. GNU Terry Pratchett. - **fail2ban** filter (`shower-admin-login.conf`) matching 401/403/429 on `/admin/login/` and jail (`shower.conf`) with `maxretry=5/findtime=600/bantime=3600`. The `nginx-deny` action was generalized to take a per-jail `nginx_deny_file` so the shower has its own deny list (forge keeps using the legacy default). - **Caddy** route on indri (`shower.ops.eblu.me` → `https://shower.tail8d86e.ts.net`). - **Pulumi** Gandi CNAME `shower.eblu.me → blumeops-proxy.fly.dev.`. - **Grafana** APM dashboard `configmap-shower-apm.yaml` (request rate, error rate, failed admin login count, latency percentiles, bandwidth, access logs) mirroring `docs-apm.json` with a `host="shower.eblu.me"` filter. - **Container** `containers/shower/default.nix` — `dockerTools.buildLayeredImage` with a nixpkgs Python and a startup wrapper that creates `/app/data/.venv`, pip-installs `adelaide-baby-shower-app==1.0.0` from the forge PyPI index on first boot, runs migrations + collectstatic, and execs gunicorn. A `local_settings.py` shim pins `DATABASES.NAME`/`MEDIA_ROOT`/`STATIC_ROOT` to absolute paths so they don't end up in site-packages. - **Docs** runbook at `docs/how-to/operations/shower-app.md` linked from the apps registry, plus changelog fragments. ### Defense layers on the public surface 1. fly nginx geo+fail2ban `$shower_banned` (per-service deny list) 2. fly nginx `limit_req zone=shower_auth` (3 r/s per Fly-Client-IP) 3. django-axes (5 fails / 1h, keyed on username+ip_address) 4. edge `/admin/` block (returns 403 for anything that isn't login/logout) ## Prerequisites for the user to do (NOT in this PR) Halted on these per request — they touch shared/manual systems: - [x] **NFS share** on sifaka: `/volume1/shower`, NFS rule for ringtail RW, `chown 1000:1000` - [ ] **1Password item** `Shower (blumeops)` in the blumeops vault with a freshly minted `secret-key` field (`openssl rand -base64 48`) — do NOT reuse anything that has lived in git - [ ] **Container build**: `mise run container-build-and-release shower`, then update `images[].newTag` in `argocd/manifests/shower/kustomization.yaml` to the resulting `v1.0.0-<sha>-nix` - [x] **DNS**: `mise run dns-up` after merge - [x] **Fly cert**: `fly certs add shower.eblu.me -a blumeops-proxy` - [ ] **Caddy push**: `mise run provision-indri -- --tags caddy` - [ ] **Fly redeploy** to pick up the new nginx block + fail2ban jail: `mise run fly-deploy` - [ ] **ArgoCD sync**: `argocd app set shower --revision shower-app-deploy && argocd app sync shower` to test from this branch before merging ## Test plan - [ ] Container builds successfully on nix-container-builder runner - [ ] Pod starts, migrations run, gunicorn answers on :8000 - [ ] `kubectl --context=k3s-ringtail -n shower logs deploy/shower` clean - [ ] `curl -sf https://shower.ops.eblu.me/` returns the splash page (tailnet) - [ ] `curl -I -H "Host: shower.eblu.me" https://blumeops-proxy.fly.dev/` returns 200 (pre-DNS verification) - [ ] `curl -I -H "Host: shower.eblu.me" https://blumeops-proxy.fly.dev/admin/users/` returns 403 (edge block) - [ ] `curl -I -H "Host: shower.eblu.me" https://blumeops-proxy.fly.dev/admin/login/` returns a Django login response - [ ] After DNS is up: `curl -I https://shower.eblu.me/` returns 200 with `X-Clacks-Overhead` - [ ] Grafana dashboard "Shower APM" appears and starts showing traffic - [ ] `mise run services-check` passes Reviewed-on: #349

# Shower App
|
|
|
|
Django web app for Adelaide / Heidi / Addie's baby shower — guest splash with
|
|
a "what did you bring?" form, raffle picker, contest-prize ranking via
|
|
QR-coded `/prizes/<token>/` URLs, and an `/host/` operator console with
|
|
drag-rank assignment solving via scipy.
|
|
|
|
## Quick Reference
|
|
|
|
| Property | Value |
|
|
|----------|-------|
|
|
| **Public URL** | `shower.eblu.me` (guest surface only — via [[flyio-proxy]]) |
|
|
| **Private URL** | `shower.ops.eblu.me` (admin + `/host/` console — Caddy on indri) |
|
|
| **Cluster** | [[ringtail]] k3s, namespace `shower` |
|
|
| **Container** | `registry.ops.eblu.me/blumeops/shower` (built from `containers/shower/default.nix`) |
|
|
| **App source** | `forge.eblu.me/eblume/adelaide-baby-shower-app` (wheel on Forgejo PyPI) |
|
|
| **Database** | SQLite on a local-path PVC (`shower-data`, RWO 2 Gi) |
|
|
| **Media (prize photos)** | NFS RWX PVC `shower-media` → `sifaka:/volume1/shower` |
|
|
| **Secrets** | `Shower (blumeops)` 1Password item → `DJANGO_SECRET_KEY` |
|
|
|
|
## Routing
|
|
|
|
```
|
|
Internet → shower.eblu.me (Fly nginx, guest-only 403s on /admin/ /host/)
|
|
│
|
|
▼
|
|
Caddy on indri (shower.ops.eblu.me — full surface)
|
|
│
|
|
▼
|
|
Tailscale ProxyGroup → k3s Service → Deployment
|
|
```
|
|
|
|
## Backups
|
|
|
|
- **SQLite** dumped via `kubectl exec` to indri's `borgmatic_k8s_dump_dir` on every 2 a.m. run (mealie-pattern entry in `borgmatic_k8s_sqlite_dumps`)
|
|
- **Media** picked up via `/Volumes/shower` (sifaka SMB mount on indri) in the main `borgmatic_source_directories` list
|
|
|
|
Both archive to sifaka + BorgBase.
