Two complementary fixes for the deploy that just landed:
1. Pod was 0/1 Running because the readiness probe sends
`Host: shower.ops.eblu.me` and the app's hardcoded ALLOWED_HOSTS
only includes `shower.eblu.me`. settings.py exposes a
DJANGO_ALLOWED_HOSTS env-var extras hook for exactly this case —
wired into the configmap.
2. `kubectl exec deploy/shower -- python -m django <cmd>` returned
"No module named django" because PYTHONPATH lived only inside the
entrypoint script. Moved PYTHONPATH, DJANGO_SETTINGS_MODULE, PATH,
and HOME into the image's Env block so exec'd shells inherit them.
The entrypoint now just runs the boot sequence; the exports are
redundant (image Env covers them) and gone.
FOD inputs are unchanged so outputHash stays valid; no fakeHash dance.

PR review caught that we didn't need an admin login surface on WAN.
App v1.0.1 adds DJANGO_PUBLIC_URL_BASE so QR codes generated from
/host/ (now tailnet-only) still point at shower.eblu.me for guest
phones — that closes the loop and lets us strip the WAN admin surface
entirely.
Container:
- bump version to 1.0.1
- outputHash → fakeHash (build will print the real one)
- entrypoint still does migrate + collectstatic before gunicorn —
the app is small enough that auto-migration is fine
Manifests:
- configmap adds DJANGO_PUBLIC_URL_BASE=https://shower.eblu.me
Fly nginx (shower.eblu.me):
- drop the /admin/(login|logout) carveout
- 403 anything under /admin/ AND /host/ with a "tailnet only" pointer
- drop the shower_auth limit_req zone and \$shower_banned geo
- drop the shower-admin-login fail2ban filter + jail
- drop the shower-deny.conf touch from start.sh
Docs:
- rename how-to docs/how-to/operations/shower-app.md →
shower-on-ringtail.md (mirrors cv-on-indri / docs-on-indri)
- new reference card docs/reference/services/shower-app.md per PR
review comment 2 (≈30s read; quick facts + cross-links)
- rewrite Defense layers section: collapses to general rate limit +
django-axes on the tailnet-side login (the only credential surface)
- rewrite the .infra.md changelog fragment to match
- add a 'Create the admin user' step (kubectl exec createsuperuser)
so first-time deploys aren't locked out
The nginx-deny action's per-jail \`nginx_deny_file\` generalization
stays — harmless future-proofing for the next public service.

Adds the Adelaide / Heidi / Addie baby shower app — a Django guest
splash, raffle picker, and prize-assignment console — on ringtail k3s.
Public landing at shower.eblu.me (via fly proxy), tailnet admin at
shower.ops.eblu.me. App source: forge.eblu.me/eblume/adelaide-baby-shower-app,
wheel-published to the Forgejo Packages PyPI index.
Manifests under argocd/manifests/shower/: NFS-backed PVC for /app/media,
local-path PVC for SQLite, ExternalSecret pulling DJANGO_SECRET_KEY from
1Password (item "Shower (blumeops)"), Tailscale ProxyGroup ingress.
Defense-in-depth for the public surface:
- /admin/ blocked at the fly edge except /admin/login/ and /admin/logout/
- shower_auth rate limit on the login path
- new fail2ban filter+jail with a per-service shower-deny.conf
(nginx-deny action generalized to accept nginx_deny_file)
- django-axes (5 / 1h) keyed on (username, ip_address)
Plus: Caddy route on indri, Pulumi gandi CNAME, Grafana APM dashboard
mirroring docs-apm.json, runbook at how-to/operations/shower-app.md,
and a service-versions entry. X-Clacks-Overhead set on the new server
block — GNU Terry Pratchett.
Build: containers/shower/default.nix uses dockerTools to ship a
nixpkgs Python plus a startup wrapper that installs the wheel into
/app/data/.venv on first boot and execs gunicorn. Lets the wheel come
from forge PyPI without pinning hashes for every transitive dep.
Prerequisites tracked in the runbook (not yet executed):
- NFS share sifaka:/volume1/shower (manual Synology step)
- 1Password item "Shower (blumeops)" with secret-key field
- container build via `mise run container-build-and-release shower`
- Pulumi dns-up after merge
- fly certs add shower.eblu.me
