# Railiance Stack — Full Deploy Runbook

> **When to use this:** Starting from a bare server (post-OS install) or rebuilding
> after a catastrophic failure. For day-to-day operations use the individual layer
> repos. See ADR-003 for layer boundaries and ADR-004 for connectivity posture.

## Pre-conditions checklist

Before starting, verify you have:

- [ ] SSH access to the selected inventory host. `Railiance01` is the current
      primary; `CoulombCore` is legacy/frozen and is not a default deployment target.
- [ ] SOPS age private key available (`~/.config/sops/age/keys.txt` or `SOPS_AGE_KEY` env)
- [ ] ops-bridge running on the workstation (needed for state hub MCP): `make mcp-http` in `~/the-custodian/state-hub/`
- [ ] Forgejo accessible (git pull on remote): SSH via `forgejo-remote:coulomb/<repo>.git`
- [ ] Gitea on coulombcore remains read-only fallback only (`gitea-remote` for emergency rollback)
- [ ] If re-provisioning from scratch: Hetzner/HostEurope API credentials decryptable via SOPS

## S1 — Infrastructure Substrate (`railiance-infra`)

```bash
# On workstation
cd ~/railiance-infra

# Provision server (skip if server already exists)
make tf-plan        # review Terraform plan
make tf-apply       # create/update server

# Converge OS baseline on the selected inventory host
ssh -i ~/.ssh/id_ops tegwick@92.205.62.239 \
  'cd ~/railiance-infra && git pull && \
   cd ansible && ansible-playbook playbooks/bootstrap.yaml \
     -c local --become -l Railiance01'

# Verify OS baseline
make verify
```

**Checkpoint:** UFW active, fail2ban running, swap enabled, nproc limits in place,
SOPS/age installed.

---

## S2 — Cluster Runtime (`railiance-cluster`)

```bash
# On the selected cluster host (Railiance01 for the current primary)
ssh -i ~/.ssh/id_ops tegwick@92.205.62.239

cd ~/railiance-cluster
make converge       # installs k3s, Helm, cert-manager, Traefik, cnpg operator
make smoke          # runs cluster health assertions
```

**Checkpoint:** k3s running, Helm available, cert-manager and Traefik pods Running,
cnpg-system namespace active.

---

## S3 — Platform Services (`railiance-platform`)

```bash
# On the current primary (kubectl available after S2)
cd ~/railiance-platform && git pull

# Deploy Forgejo database cluster (production on railiance01)
# Credentials via SOPS — see railiance-platform docs/forgejo-backup.md
make forgejo-db-deploy
make forgejo-db-status

# Legacy coulombcore Gitea DB (read-only fallback — retain until T12 retires Gitea)
# make db-deploy && make db-status

# Deploy an optional cache only when a named workload requirement and custody
# path exist. Cache installation is not an unconditional S3 baseline step.
```

**Checkpoint:** `kubectl get cluster -n databases` shows `forgejo-db` healthy
on Railiance01; optional services are present only when explicitly required.

---

## S4 — Developer Enablement (`railiance-enablement`)

Validate the consumer-facing paved paths; S4 does not deploy the forge runtime:

```bash
cd ~/railiance-enablement && git pull
make check
make test
```

---

## S5 — Workloads & Experience (`railiance-apps`)

```bash
# Verify the forge through its operational owner.
cd ~/railiance-forge && git pull
make gitea-status

# Deploy each application through its owning rapp/release runbook. S5 does not
# own the forge runtime or generic rail/template behavior.
```

**Checkpoint:** `https://forgejo.coulomb.social` serves HTTPS; git clone/push via
`forgejo-remote`; state-hub `/state/health` returns 200.

---

## ops-bridge tunnel setup (workstation)

After S2 is up, establish the persistent tunnels from the workstation:

```bash
bridge up state-hub-coulombcore       # state-hub HTTP (port 18000 remote)
bridge up state-hub-mcp-coulombcore   # state-hub MCP (port 18001 remote)
bridge up k3s-api-coulombcore         # CoulombCore k3s API (port 16443 local)
bridge up k3s-api-railiance01         # Railiance01 k3s API (port 16444 local)
```

Verify: `bridge status` shows the tunnels needed for the selected host connected.

## Layer dependency chain

```
S1 (infra) → S2 (cluster) → S3 (platform) → S4 (enablement) → S5 (workloads)
```

Each layer must be fully converged and verified before starting the next.
Never configure S2 concerns from S3+ repos (ADR-003 boundary rule).
