# Forgejo Production Decisions (Wave 1)

Date: 2026-07-03  
Workplans: `RAIL-HO-WP-0005-T02`, `CUST-WP-0054-T04`  
Operator input: 2026-07-03

## Decision log

| # | Topic | Decision | Status | Evidence (2026-07-03) |
| --- | --- | --- | --- | --- |
| 1 | **Production hostname** | `forgejo.coulomb.social` | **decided** | DNS A → `92.205.62.239` (railiance01); HTTPS reaches Traefik on railiance01 |
| 2 | Exposure model | Private HTTPS via railiance01 Traefik ingress + cert-manager `letsencrypt-prod` | **decided** | Same pattern as Gitea (`manifests/forgejo-ingress.yaml` in `railiance-apps`) |
| 2b | Deployment pattern | `gitea-charts/gitea` **12.5.0** Helm + Forgejo image; CNPG `forgejo-db` in `railiance-platform`; Makefile in `railiance-apps` | **decided** | Chart 12.6+ requires Gitea 1.26 `config edit-ini` (incompatible with Forgejo 11); see `railiance-apps/docs/forgejo-on-railiance01.md` |
| 2c | Live deploy | Forgejo pod + ingress + TLS on railiance01 | **done** (2026-07-03) | `make forgejo-smoke` → HTTP 200 + OCI `/v2/` 401 challenge; cert `forgejo-tls` Ready |
| 3 | Gitea during transition | `gitea.coulomb.social` on coulombcore remains canonical **until** Forgejo restore/migration drills pass; then read-only mirror | unchanged | Per `RAIL-HO-WP-0005` safety contract |
| 4 | SMTP / password reset | **IONOS** SMTP; sender `forgejo@coulomb.social`; OpenBao/ESO mailer on railiance01 | **done** (2026-07-08) | `smtp.ionos.de:587` + `smtp+starttls`; T06 verified |
| 5 | Package registry scope | **Multi-ecosystem (Option C):** OCI + **npm** + generic; PyPI/Go/Maven/Helm as inventory proves need | **decided** (2026-07-08) | OCI live; npm is launch requirement — see § Package scope |
| 6 | Actions runner model | **In-cluster** on railiance01: `forgejo-runner` Deployment + DinD (`railiance01-build-01`) | **done** (2026-07-03) | Runner 2/2 Ready; coulombcore host runner disabled; `image-build` probe pushed OCI image via org secrets |
| 7 | Backup target + retention | TBD | open | — |
| 8 | Cutover mode | TBD (staged per-repo vs freeze-all) | open | — |

## Hostname decision detail

**Chosen hostname:** `https://forgejo.coulomb.social`

| Field | Value |
| --- | --- |
| DNS | `forgejo.coulomb.social` → `92.205.62.239` (railiance01) |
| Edge | railiance01 k3s Traefik (`kube-system/traefik` LoadBalancer) |
| Target machine | railiance01 (production home per `CUST-WP-0054`) |
| Canonical git remote (post-cutover) | `https://forgejo.coulomb.social/coulomb/<repo>.git` |
| OCI registry (post-cutover) | `forgejo.coulomb.social/coulomb/<image>` |

### Live probe (2026-07-03, post-deploy)

```bash
getent hosts forgejo.coulomb.social   # 92.205.62.239
curl -fsS -o /dev/null -w '%{http_code}\n' https://forgejo.coulomb.social/   # 200
curl -sSI -X GET https://forgejo.coulomb.social/v2/ | grep -i docker-distribution  # registry/2.0
KUBECONFIG=~/.kube/config-hosteurope kubectl get pods,ingress,certificate -n forgejo
```

Forgejo is serving HTTPS with a valid Let's Encrypt cert. Gitea on coulombcore
remains canonical for git remotes until migration drills pass.

### Implications for CUST-WP-0054

- Wave 1 can proceed with a fixed hostname for overlays, ingress manifests, and
  CI `IMAGE_REPOSITORY` variables.
- State Hub / sweep checkouts on railiance01 (T05) should clone from
  `forgejo.coulomb.social` once cutover completes.
- Runners and image-build CI are proven; first repo migration pilot
  (`glas-harness`) documents git/SSH/CI routing in
  `docs/forgejo-repo-migration-pilot-glas-harness.md`.
- Remaining blockers for production cutover: backup target (T02), cutover mode
  confirmation (T02), npm/package hardening (T07), and production repo migration
  (`RAIL-HO-WP-0005-T11`).

## SMTP decision (IONOS) — 2026-07-07

**Provider:** IONOS mail for `coulomb.social` and subdomains (operator owns DNS zone
via IONOS; mailboxes provisioned in IONOS control panel).

**Recommended Forgejo mailer settings** (non-secret; password in
`railiance-apps/helm/forgejo-secrets.sops.yaml`):

| Field | Value |
| --- | --- |
| `MAILER_TYPE` | `smtp` |
| `HOST` | `smtp.ionos.com:587` (EU accounts may use `smtp.ionos.de:587`) |
| `IS_TLS_ENABLED` | `true` (STARTTLS on 587) |
| `FROM` | `forgejo@coulomb.social` (or dedicated `noreply@…` mailbox) |
| `USER` | full mailbox address (same as `FROM` unless using a shared relay mailbox) |
| `PASSWD` | IONOS mailbox password — SOPS only, never Git plaintext |

**Operator setup checklist:**

1. Create mailbox in IONOS (e.g. `forgejo@coulomb.social`).
2. Confirm SPF includes IONOS (`include:_spf-eu.ionos.com` or current IONOS
   guidance for the zone).
3. Enable DKIM in IONOS for `coulomb.social` if offered.
4. Store mailbox password in `helm/forgejo-secrets.sops.yaml` under
   `gitea.config.mailer.PASSWD`; redeploy Forgejo.
5. T06 gate: trigger password reset for a controlled non-admin test account;
   confirm delivery and link works.

**Implementation:** `railiance-apps/docs/forgejo-on-railiance01.md` (SMTP section).
Password in OpenBao `platform/workloads/forgejo/forgejo-mailer` (field `PASSWD`).

## Package scope decision (Option C) — 2026-07-08

**Operator choice:** Multi-ecosystem registry — not OCI-only at launch.

| Phase | Package types | Status |
| --- | --- | --- |
| **Now (proven)** | OCI container images | Live — tier 0–3 CI (`container-build-push` templates) |
| **Launch requirement** | **npm** | Decide → implement in T07 (auth, publish/pull docs, CI template) |
| **In scope** | Generic (release tarballs/binaries) | Enable with retention policy |
| **As needed** | PyPI, Go, Maven, Helm | Add per repo only after T01 inventory shows Gitea package data or an explicit consumer need |

**Rationale:** Railiance needs npm publishing; other ecosystems follow evidence, not
a big-bang enable-everything default.

**Implications:**

- T07 expands beyond OCI smoke: npm publish/pull runbook, org/repo token policy,
  retention/cleanup for non-OCI blobs.
- T09 backups must include **all enabled package types** under `/data/packages`.
- T01 authenticated Gitea inventory should classify existing npm (and other) package
  data before cutover waves.

**Forgejo endpoints (post-cutover):**

| Type | URL pattern |
| --- | --- |
| OCI | `forgejo.coulomb.social/coulomb/<image>` |
| npm | `https://forgejo.coulomb.social/api/packages/coulomb/npm/` (configure scope in T07) |
| Generic | per-repo generic package API |

## Open decisions (need operator input)

1. ~~SMTP provider~~ — **done** (IONOS + T06 verified 2026-07-08)
2. ~~Package types~~ — **done: Option C** (OCI + npm + generic; others as needed)
3. ~~Actions runner~~ — **done** (in-cluster, ADR-004)
4. Backup destination and restore cadence
5. Cutover: staged project-by-project vs single freeze window
