# Deploy Trust Service and Control Plane to the Railiance reef

Deploy the hosted Trust Service (`service/app.py`, WP-0006) and the
Control Plane interactive UI (`service/control_plane_app.py`, WP-0009-T04)
to Railiance infrastructure-as-code, on a rail hosted in `reef-railiance`'s
grouped home substrate, fronted by the subdomain `revenue.coulomb.social`.

This is an infrastructure delivery workplan, not a governance one: it does
not authorize a real Phase to go live for any repo. That gate remains
`workplans/TREV-WP-0008-governance-and-pilot-rollout.md` T05, independent
of whether the software is reachable at a public URL. The Control Plane UI
itself already carries this disclaimer in its footer
(`service/control_plane_templates/base.html`) and will continue to once
deployed.

**Reference deployment**: `railiance-vergabe-teilnahme` /
`railiance-apps/charts/vergabe-teilnahme` is the closest existing precedent
— a Django app, its own Postgres, a Helm chart living in `railiance-apps`,
an `Ingress` with `cert-manager.io/cluster-issuer: letsencrypt-prod`, and
runtime secrets via an `ExternalSecret` reading an OpenBao
`ClusterSecretStore`. `issue-core` is a second precedent using a different
pattern — its own repo carries `k8s/railiance` and an ArgoCD `Application`
points `repoURL` directly at that repo rather than at `railiance-apps`. T01
below has to pick between these two patterns (or a third) rather than
assume one.

```task
id: TREV-WP-0011-T01
status: todo
priority: high
human_accept_required: true
state_hub_task_id: "8dffe5e1-6f2b-4020-ac07-a108a8fc2edc"
```

**Decide the deployment pattern (human gate).** Concretely:

- **Manifest home**: does `target-revenue` carry its own `k8s/railiance`
  path (like `issue-core`) with an ArgoCD `Application` pointing straight
  at this repo, or does the Helm chart/Ingress/manifests live in
  `railiance-apps/charts/target-revenue` alongside `vergabe-teilnahme`
  (this repo's TRSL licensing and its being a monetization-framework repo,
  not an application repo, may argue for keeping deploy manifests
  out-of-tree)?
- **Process topology**: `service/app.py` (Trust Service) and
  `service/control_plane_app.py` (Control Plane UI) are two separate
  FastAPI `app` objects today, sharing the same Postgres and the same
  Ed25519 signing key. Deploy as two Deployments/Services behind one
  Ingress with path-based routing, or mount one inside the other
  (`app.mount("/control-plane", control_plane_app)`) into a single
  process/image? The latter needs a small code change (WP-0009-T04's
  Optional-Next-Step note flagged this as undecided); the former needs no
  code change but two sets of secrets/probes.
- **Database**: a dedicated CNPG (`CloudNativePG`) `Cluster` for this
  workload's Postgres (matching the `cnpg-option-a-*` manifests already
  in `railiance-apps`), sized appropriately for a pilot-scale Trust
  Service instance — not the shared state-hub Postgres, per this
  project's own standing rule about never reusing that instance for
  hosted-service data.
- **Secrets**: which values go through OpenBao + `ExternalSecret`
  (`TRF_SIGNING_KEY_HEX`, `TRF_CONTROL_PLANE_SECRET_KEY`,
  `TRF_DATABASE_URL`/the `trf_app` role password) versus which, if any,
  are fine as plain Helm `values.yaml` — following the
  `reuse-surface-runtime-externalsecret.yaml` pattern, one
  `ClusterSecretStore` per workload namespace.
- **Subdomain and TLS**: confirm `revenue.coulomb.social` DNS is (or will
  be) pointed at the Railiance ingress, and that `letsencrypt-prod` issuing
  for a `coulomb.social` subdomain has no unresolved prerequisite (SAN
  limits, existing wildcard, etc.) — check `railiance-infra`/
  `railiance-platform` docs rather than assuming parity with
  `whywhynot.de`.
- **Founding credential bootstrap**: how the first `binky` admin
  credential is seeded into the deployed database — an idempotent
  migration-adjacent script, or a documented one-time manual `kubectl
  exec`/`psql` step, consistent with how `railiance-apps`/`railiance-platform`
  already handle comparable one-time bootstrap actions.

Record the decision here (Result) before any manifest is written — this
gate exists because every later task in this workplan assumes a specific
answer to each bullet above.

```task

status: todo
priority: high
state_hub_task_id: "d4b3dae4-eb2a-4bed-bc10-5ce90d972cec"
```

**Containerize.** Add a `Dockerfile` (and, if T01 decided on two
processes, two images or one image with two entrypoints/commands) building
the `service` extras (`fastapi`, `uvicorn`, `jinja2`, `itsdangerous`,
`python-multipart`, `psycopg[binary]`, `psycopg-pool`) plus
`static/whynot-design` and `control_plane_templates/` as part of the image
— nothing in T04's implementation currently assumes local filesystem paths
outside the package, but this should be verified for a container context
(non-root user, read-only root filesystem where the app's own static/
template files don't need write access). Push to
`forgejo.coulomb.social/coulomb/target-revenue` per the existing image
registry convention (`vergabe-teilnahme`'s `values.yaml` `image.repository`
pattern).

state_hub_task_id: "06567eb5-d924-4100-9cd5-19478121c3c7"
```

**Provision the database and secrets** per T01's decision: a CNPG
`Cluster`, the `0001`–`0006` migrations applied against it (as a Job, an
init step, or a documented manual run — decide which, consistent with
however `railiance-apps`'s other CNPG-backed workloads handle first-boot
migration), the `trf_app` role and its grants (already defined in the
migration files themselves), an `OpenBao` `ClusterSecretStore` +
`ExternalSecret` surfacing `TRF_SIGNING_KEY_HEX`,
`TRF_CONTROL_PLANE_SECRET_KEY`, and the `trf_app` password/DSN into the
workload's namespace.

```

**Helm chart, Ingress, and ArgoCD wiring.** Following T01's chosen home
(own-repo `k8s/railiance` vs. `railiance-apps/charts/target-revenue`):
Deployment(s)/Service(s)/Ingress for `revenue.coulomb.social` with
`cert-manager.io/cluster-issuer: letsencrypt-prod` and TLS, readiness/
liveness probes against a real health path (neither `service/app.py` nor
`control_plane_app.py` currently exposes one — add a trivial `/healthz` to
each rather than probing an authenticated or Postgres-dependent route),
and an ArgoCD `Application` (`railiance-tenants` project, matching
`issue-core.application.yaml`'s shape) with automated sync.

```task
id: TREV-WP-0011-T05
status: todo
priority: medium
state_hub_task_id: "37847415-19c4-43b5-8b0d-de7a4211bfdd"
```

**Bootstrap and smoke-test the live deployment.** Seed the founding
`binky` admin credential per T01's decision, confirm
`https://revenue.coulomb.social/login` is reachable and TLS-valid, sign in,
register a throwaway test Phase (id clearly marked as a smoke test, not a
real candidate), append a Development Credit entry, confirm the audit log
and metrics reflect it, then decide whether to leave that smoke-test Phase
in place (clearly labeled) or remove it — Phase Manifests are append-only
by design (no delete path), so if a smoke test is unacceptable to leave
behind, use a disposable local/staging instance for this step, not the
production deployment, and only do a read-only login check against the
real one. Update `README.md`'s WP-0011 summary row and this workplan's
Result sections; add a short deployment note (URL, how to sign in, that no
Phase go-live is authorized by deployment alone) to `docs/` or `SCOPE.md`
as appropriate.
