RAILIANCE-WP-0002 T05+T06 done: vergabe-teilnahme is live at https://vergabe-teilnahme.whywhynot.de

Thin Helm chart in charts/vergabe-teilnahme (Deployment + Service), plain values overlay in helm/vergabe-teilnahme-values.yaml, ingress + cert-manager TLS in manifests/vergabe-teilnahme-ingress.yaml. Makefile targets vergabe-dry-run|deploy|ingress-deploy|status|migrate|seed|superuser|logs. Secrets stay in K8s (vergabe-app-credentials + vergabe-teilnahme-env) — no SOPS needed.

Live: pod Running 1/1, /health/ 200 ok, /ausschreibungen/dashboard/ renders Übersicht, /admin/login/ renders Django admin (German). cert-manager issued vergabe-teilnahme-tls in ~35s.

Workplan T07 (migrate+seed+smoke) marked in_progress; migrate completed inline (10+ apps migrated) so the dashboard would render.

 **Done when:** `make vergabe-deploy` renders cleanly with `--dry-run`

+**Done (2026-05-19):**
+
+- Chart approach: thin in-repo chart `charts/vergabe-teilnahme/` rather
+  than SOPS-encrypted values, because the only sensitive material
+  (`SECRET_KEY`, `DATABASE_URL`) lives in K8s Secrets (cnpg's
+  `vergabe-app-credentials` + the assembled `vergabe-teilnahme-env`),
+  not in Helm values. `helm/vergabe-teilnahme-values.yaml` is therefore
+  plain YAML — image tag, hostnames, no secrets.
+- `make vergabe-dry-run` renders 2 objects (Deployment + Service);
+  `grep -iE 'SECRET_KEY=|DATABASE_URL=|password'` returns empty.
+- Deploy revision 2 is live: pod Running 1/1, probes green. The
+  HTTP-probe `httpGet.httpHeaders[Host]` is set to the public hostname
+  so Django's `ALLOWED_HOSTS` check passes for kube-probe (the v1
+  fix took one iteration — earlier attempts failed liveness with HTTP
+  400 because the probe sent `Host: 10.42.x.x:8000`).
+- `Makefile` targets added: `vergabe-dry-run`, `vergabe-deploy`,
+  `vergabe-ingress-deploy`, `vergabe-status`, `vergabe-migrate`,
+  `vergabe-seed`, `vergabe-superuser`, `vergabe-logs`.
+
+**Lesson recorded:** the base64-generated bootstrap password contains
+`=`, `+`, `/`; embedding it raw in `DATABASE_URL` confuses
+`dj-database-url` (it parses `:password@host:5432/db` and the `=`
+broke the DB name into 80 characters). The Secret now stores a
+URL-encoded password inside `DATABASE_URL` while the raw password
+remains in `vergabe-app-credentials.password`. Future apps should
+either URL-encode at Secret-build time or use individual env vars.
