+# Deploy reuse-surface federation hub on railiance01
+
+Companion to **`reuse-surface` REUSE-WP-0011**. Own the S5 Helm release,
+ingress, and operator targets for the federation hub service on production
+cluster node `railiance01` (`92.205.130.254`).
+
+## Goal
+
+Expose the helix_forge federation hub API at a stable TLS endpoint so repos can
+register capability index URLs via `reuse-surface hub` without per-machine
+`sources.yaml` maintenance.
+
+**Default hostname (confirm with operator):** `https://reuse-hub.whywhynot.de`
+
+## Upstream dependency
+
+| Upstream | Workplan | Required artifact |
+|---|---|---|
+| Hub service + image | `reuse-surface` REUSE-WP-0011 | Container image `gitea.coulomb.social/coulomb/reuse-surface-hub:<tag>`, `/health` probe path |
+
+Do not deploy until REUSE-WP-0011-T04 publishes a buildable image and documents
+the required environment variables.
+
+## Placement
+
+Follow the established `inter-hub` pattern in this repo:
+
+- `charts/reuse-surface-hub/` — Helm chart (Deployment, Service, Ingress, PVC)
+- `helm/reuse-surface-hub-values.yaml` — non-secret overrides (image tag, host)
+- SOPS secret handoff for `REUSE_SURFACE_HUB_TOKEN` (write token)
+- `Makefile` targets: `reuse-hub-dry-run`, `reuse-hub-deploy`, `reuse-hub-status`, `reuse-hub-logs`
+
+Cross-repo coordination:
+
+| Concern | Owner |
+|---|---|
+| Application image and API | `reuse-surface` |
+| Helm release and ingress | `railiance-apps` (this workplan) |
+| OCI registry push | `railiance-forge` guidance + `reuse-surface` CI/docs |
+| DNS A record | DNS owner of `whywhynot.de` |
+| Traefik / cert-manager | `railiance-cluster` / `railiance-platform` (reuse) |
+
+## Safety contract
+
+- Do not commit decrypted SOPS values or hub write tokens.
+- Pin image tags in `helm/reuse-surface-hub-values.yaml`; no `:latest` in production.
+- Use a dedicated namespace (default `reuse-surface-hub`).
+- PVC for SQLite data; document backup expectation in runbook.
+
+---
+
+## Scaffold Helm Chart For reuse-surface-hub
+
+```task
+id: RAILIANCE-WP-0007-T01
+status: done
+priority: high
+```
+
+Create `charts/reuse-surface-hub/` modeled on `charts/inter-hub/` with:
+
+- Deployment exposing port `8000`
+- ClusterIP Service
+- Optional PVC mount at `/data` for SQLite persistence
+- Ingress (Traefik + cert-manager) disabled by default until hostname confirmed
+- Probes targeting `GET /health`
+- `envSecretName` for hub token and optional config
+
+## Add Values, SOPS Template, And Makefile Targets
+
+```task
+id: RAILIANCE-WP-0007-T02
+status: done
+priority: high
+```
+
+Add:
+
+- `helm/reuse-surface-hub-values.yaml` with image repository
+  `gitea.coulomb.social/coulomb/reuse-surface-hub` and placeholder tag
+- Documented SOPS secret template path (mirror `inter-hub-env` pattern)
+- Makefile variables and targets: `reuse-hub-dry-run`, `reuse-hub-deploy`,
+  `reuse-hub-status`, `reuse-hub-logs`
+
+## Configure Ingress And Hostname
+
+```task
+id: RAILIANCE-WP-0007-T03
+status: wait
+priority: medium
+```
+
+Enable ingress in values with:
+
+- `ingress.host: reuse-hub.whywhynot.de` (or operator-confirmed host)
+- `cert-manager.io/cluster-issuer: letsencrypt-prod`
+- Traefik annotations matching `vergabe-teilnahme` / `inter-hub`
+
+**Blocked on:** DNS A record and hostname approval.
+
+## Deploy Release To railiance01
+
+```task
+id: RAILIANCE-WP-0007-T04
+status: wait
+priority: medium
+```
+
+When REUSE-WP-0011-T04 image is available:
+
+1. `make reuse-hub-dry-run` — inspect rendered manifests
+2. Apply SOPS secret for hub token
+3. `make reuse-hub-deploy`
+4. Confirm certificate issued and `/health` returns 200
+
+## Post-Deploy Verification And Runbook
+
+```task
+id: RAILIANCE-WP-0007-T05
+status: todo
+priority: low
+```
+
+Add `docs/reuse-surface-hub-on-railiance01.md` with:
+
+- Namespace, release name, image promotion steps
+- Secret rotation notes
+- Smoke checks: `reuse-surface hub status --hub-url https://reuse-hub.whywhynot.de`
+- Link back to `reuse-surface/docs/RegistryFederation.md`
