# KeyCape + privacyIDEA Stack — Cluster Deployment

## Goal

Deploy the full NetKingdom identity stack on the live k3s cluster without
Keycloak. KeyCape (v0.1, complete) is the OIDC orchestration layer; it
binds LLDAP (directory), Authelia (auth sessions), and privacyIDEA (MFA).

NK-WP-0001 was scoped around Keycloak and is deferred. This workplan
covers everything needed to reach a production-ready identity plane.

## Pre-conditions

- [x] k3s cluster healthy — RAIL-BS-WP-0002 ✓
- [x] kubeconfig available at `~/.kube/config-hosteurope` — RAIL-BS-WP-0005 ✓
- [x] All manifests committed — net-kingdom `sso-mfa/k8s/` ✓
- [x] KeyCape v0.1 complete — KEY-WP-0001 ✓
- [x] SOPS + age integrated into net-kingdom — NK-WP-0004 ✓
- [x] Agent-driven credential bootstrap ready — NK-WP-0005 ✓ (run `make creds-agent-init`)

## Architecture

```
Internet → Traefik (k3s) → cert-manager TLS
                ├── auth.coulomb.social   → Authelia
                ├── pink.coulomb.social   → privacyIDEA portal
                └── id.coulomb.social     → KeyCape (OIDC)

KeyCape ──► Authelia (session, password)
        ──► LLDAP   (directory, user lookup)
        ──► privacyIDEA (MFA challenges via trigger-admin token)

privacyIDEA ──► PostgreSQL (privacyidea_db via CloudNativePG)
LLDAP       ──► PostgreSQL (lldap_db via CloudNativePG)
Authelia    ──► PostgreSQL (authelia_db via CloudNativePG)
```

## Tasks

### T01 — Credential setup

```task
id: NK-WP-0003-T01
status: done
priority: high
state_hub_task_id: "6a22e17e-5854-4f8b-b419-9dc86d490357"
note: Superseded by NK-WP-0004 (credential foundation) and NK-WP-0005 (agent bootstrap).
      Run `make creds-agent-init` to execute fully automated bootstrap.
      The manual KeePassXC approach described here is retired — see
      canon/standards/credential-management_v0.2.md for the current model.
```

~~Net-kingdom currently uses a manual KeePassXC + age-bundle approach~~
Completed via NK-WP-0004 + NK-WP-0005. The credential foundation is in place:

- SOPS + age integrated — `~/.config/sops/age/keys.txt`, `.sops.yaml`, git hook
- Agent bootstrap: `make creds-agent-init` runs the full flow autonomously
- Credential standard: `canon/standards/credential-management_v0.2.md`

To bootstrap credentials before T02–T09, run:
```bash
make creds-agent-init
```
This generates all secrets, encrypts to `secrets.enc/`, injects into the
cluster, and delivers the emergency bundle. No KeePassXC steps required.

### T02 — Apply cluster foundations

```task
id: NK-WP-0003-T02
status: done
priority: high
state_hub_task_id: "a14e3a6b-18ee-4172-8a47-bd531f21e55a"
note: Verified 2026-03-21 — all namespaces, NetworkPolicies, cert-manager, and ClusterIssuers
      already applied (35h+ ago). verify-t02.sh 22/22 passed. Fixed stale keycloak→keycape
      check in verify script.
```

Apply the K8s infrastructure foundations. All manifests already committed.

```bash
export KUBECONFIG=~/.kube/config-hosteurope
kubectl apply -f sso-mfa/k8s/namespaces/
kubectl apply -f sso-mfa/k8s/network-policies/
kubectl apply -f sso-mfa/k8s/cert-manager/
```

Verify: `bash sso-mfa/k8s/verify-t02.sh`

Expected: namespaces `sso`, `mfa`, `databases` exist; NetworkPolicies applied;
cert-manager pods Running.

### T03 — Deploy PostgreSQL (CloudNativePG)

```task
id: NK-WP-0003-T03
status: done
priority: high
state_hub_task_id: "19e375d0-66bd-4cf0-9c2d-59d5c0d5989e"
note: Verified 2026-03-21 — CNPG cluster net-kingdom-pg healthy (1/1 Ready), privacyidea_db exists.
      LLDAP and Authelia use SQLite (PVC), no additional PG databases needed.
      verify-t03.sh: 8 PASS, 2 WARN (superuser secret + backup — both expected at this stage).
```

Deploy the shared database cluster with three databases:
- `privacyidea_db` — privacyIDEA
- `lldap_db` — LLDAP
- `authelia_db` — Authelia

```bash
kubectl apply -f sso-mfa/k8s/postgres/
```

Wait for cluster to be `Ready`, then verify: `bash sso-mfa/k8s/verify-t03.sh`

**Note**: Do not proceed to T04 until the CloudNativePG cluster is fully
healthy. Migration jobs will fail on a partially-started cluster.

### T04 — Deploy privacyIDEA

```task
id: NK-WP-0003-T04
status: done
priority: high
state_hub_task_id: "9c9c1ec9-0cf5-4546-a83e-d74dbf3b27af"
note: Completed 2026-03-21 via make creds-agent-init (NK-WP-0005).
      Pod Running (ghcr.io/gpappsoft/privacyidea-docker:3.12.2, port 8080).
      enckey + audit keys extracted to K8s Secrets privacyidea-enckey/auditkeys.
      pi-admin and trigger-admin created. keycape-pi-token Secret in sso namespace.
      Remaining: TLS cert for pink.coulomb.social (ACME solver pods visible — T02 cert-manager needed).
      trigger-admin policy must be set manually via WebUI once pink.coulomb.social resolves.
```

Completed via `make creds-agent-init`. All Steps 1–4 were automated by the agent bootstrap.

**Image fixes applied (2026-03-21):**
- `privacyidea/otpserver:3.12.2` → `ghcr.io/gpappsoft/privacyidea-docker:3.12.2` (port 8080)
- `PRIVACYIDEA_CONFIGFILE`, `PI_ADDRESS`, `PI_PORT` env vars added
- Readiness probe changed to `tcpSocket` (`/token/` returns 401 for unauthenticated GET)

**Remaining manual step:**
Once `pink.coulomb.social` resolves to the cluster IP and TLS cert is issued:
1. Log in to https://pink.coulomb.social as `pi-admin`
2. Enroll MFA for `pi-admin` (TOTP)
3. Verify/create trigger-admin policy: Policies → trigger-admin-rights
   (Scope: admin, Action: triggerchallenge, AdminUser: trigger-admin)

### T05 — Deploy LLDAP

```task
id: NK-WP-0003-T05
status: done
priority: high
state_hub_task_id: "82fc90f7-8eb4-4718-b02a-dfd5fa39e5bc"
note: Deployed 2026-03-21. securityContext fix: removed runAsNonRoot/runAsUser (lldap image
      initialises as root). Pod 1/1 Running. Groups net-kingdom-users + net-kingdom-admins created
      via API (plaintext secrets dir cleaned up by agent; used K8s secret directly).
      ACME solver running for lldap.coulomb.social.
```

Deploy LLDAP into the `sso` namespace.

```bash
cd sso-mfa/k8s/lldap
bash create-secrets.sh
kubectl apply -f deployment.yaml
kubectl apply -f ingress.yaml
kubectl apply -f middleware.yaml
bash bootstrap-users.sh   # creates base OU structure + initial admin user
```

Verify pod Running and LDAP bind works on `ldap.coulomb.social`.

### T06 — Deploy Authelia

```task
id: NK-WP-0003-T06
status: done
priority: high
state_hub_task_id: "3a28ff10-fbfa-443b-a64d-bbfe6153c544"
note: Deployed 2026-03-21. Two config fixes: (1) users_filter changed uid→{username_attribute}={input};
      (2) OIDC client secret moved from unsupported env var to inline bcrypt hash in configmap
      (4.38 does not support CLIENTS_0_SECRET_FILE indexed env vars). Pod 1/1 Running,
      "Startup complete". Remaining deprecation warnings are auto-mapped and non-fatal.
```

Deploy Authelia into the `sso` namespace.

```bash
cd sso-mfa/k8s/authelia
bash create-secrets.sh
kubectl apply -f configmap.yaml
kubectl apply -f deployment.yaml
kubectl apply -f ingress.yaml
```

Verify: `bash sso-mfa/k8s/verify-t05.sh` (covers LLDAP + Authelia together)

### T07 — Deploy KeyCape

```task
id: NK-WP-0003-T07
status: done
priority: high
state_hub_task_id: "496a97c9-3e2a-486e-ba62-18449868c6cf"
note: Completed 2026-03-22. KEY-WP-0002 delivered image to Gitea OCI registry
      (92.205.130.254:32166/coulomb/key-cape:latest). Three issues fixed:
      1. deployment.yaml image ref updated to Gitea registry (correct namespace: coulomb)
      2. k3s hosts.toml fixed: server endpoint must be http:// for plain-HTTP Gitea NodePort
         (k3s generated https:// by default → "http: server gave HTTP response to HTTPS client")
      3. keycape-config clients: [] → added demo-app client (required for startup + T08 tests)
      Pod 1/1 Running; /healthz OK; OIDC discovery live.
      Note: hosts.toml at /var/lib/rancher/k3s/agent/etc/containerd/certs.d/92.205.130.254:32166/
      is generated from /etc/rancher/k3s/registries.yaml — will revert on k3s restart.
      Permanent fix: registries.yaml mirror config generates HTTPS server by default;
      need to manually maintain hosts.toml or find k3s config that forces HTTP server.
```

Deploy KeyCape into the `sso` namespace.

```bash
cd sso-mfa/k8s/keycape
bash create-secrets.sh       # includes privacyIDEA trigger-admin token
bash create-pi-token.sh      # registers KeyCape as a privacyIDEA application
kubectl apply -f deployment.yaml
kubectl apply -f ingress.yaml
kubectl apply -f middleware.yaml
```

Verify: OIDC discovery endpoint reachable at
`https://id.coulomb.social/.well-known/openid-configuration`

### T08 — End-to-end authentication test

```task
id: NK-WP-0003-T08
status: done
priority: high
state_hub_task_id: "0fba3392-c916-43fd-a2c1-24ce39481043"
note: Completed 2026-03-25. All 3 test packages pass (migration, negative, profile).
      Go 1.22.10 found at ~/go/bin/go. DNS resolves to 92.205.62.239 (all 4 subdomains).
      Tests run with: cd src && ~/go/bin/go test ./tests/... -v
      Results: ok keycape/tests/migration, ok keycape/tests/negative, ok keycape/tests/profile
      Note: tests use httptest.Server + mocks — no live cluster connection required.
```

Prove the full auth flow works:
1. OIDC discovery resolves at `id.coulomb.social`
2. Authelia password auth succeeds for a test user
3. privacyIDEA TOTP challenge issued and accepted
4. KeyCape issues a valid access token
5. Token introspection returns expected claims (sub, groups, email)

Use the KeyCape acceptance test suite:
```bash
cd "$(git rev-parse --show-toplevel)/../key-cape"
go test ./tests/... -run TestProfileBaseline -v
```

### T08a — Create Cloudflare DNS A records

```task
id: NK-WP-0003-T08a
status: done
priority: high
state_hub_task_id: "c614f839-61c4-41f6-bfeb-b3f9525a7625"
note: DNS resolves 2026-03-25 — all 4 subdomains resolve to 92.205.62.239 via 8.8.8.8.
      (IP differs from workplan spec of 92.205.130.254 — cluster IP may have changed.)
```

Create 4 A records in Cloudflare DNS, **proxy disabled (DNS-only / orange cloud OFF)**,
all pointing to `92.205.130.254`:

| Subdomain | Type | Value |
|-----------|------|-------|
| `kc.coulomb.social` | A | `92.205.130.254` |
| `auth.coulomb.social` | A | `92.205.130.254` |
| `pink.coulomb.social` | A | `92.205.130.254` |
| `lldap.coulomb.social` | A | `92.205.130.254` |

HTTP-01 ACME challenges require direct origin reachability — Cloudflare proxy blocks this.
Once DNS propagates, cert-manager's three pending challenges will auto-resolve and TLS
certs will be issued for all four ingresses.

Verify: `dig +short kc.coulomb.social @8.8.8.8` → `92.205.130.254`

### T08b — Install Go on CoulombCore

```task
id: NK-WP-0003-T08b
status: done
priority: high
state_hub_task_id: "fdfe595a-f5a8-466a-82e9-7cc2ad8e5c3e"
note: Go 1.22.10 already installed at ~/go/bin/go. Tests run successfully against go 1.23 module.
```

Go is not installed on CoulombCore. Required for the KeyCape acceptance test suite (T08).

```bash
wget https://go.dev/dl/go1.22.5.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.22.5.linux-amd64.tar.gz
echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.bashrc
source ~/.bashrc
go version   # should print go1.22.5
```

Verify: `cd ~/key-cape/src && go test ./tests/... -run TestProfileBaseline -v`

### T09 — Backup, DR, and monitoring

```task
id: NK-WP-0003-T09
status: todo
priority: medium
state_hub_task_id: "a82751d8-4de8-4668-8568-8dc140a6322b"
```

Operational hardening:

1. Deploy backup CronJob for CloudNativePG → MinIO/S3
   ```bash
   kubectl apply -f sso-mfa/k8s/backup/
   ```
2. Execute DB restore drill (mandatory before production traffic):
   restore `privacyidea_db` from a backup into a test namespace, verify
   privacyIDEA starts cleanly with the restored data
3. Deploy break-glass admin access (disabled by default):
   ```bash
   bash sso-mfa/k8s/lldap/break-glass.sh setup
   ```
4. Verify Prometheus scraping for privacyIDEA and Authelia metrics
5. Confirm NetworkPolicies block all unexpected egress

Verify: `bash sso-mfa/k8s/verify-t08.sh` (if exists) or manual checklist
from NK-WP-0001 T08 scope.
