# Poimen Memory — ArgoCD Deployment (Bundled into Homelab)

## Status

✅ **Memory database bundled into homelab wave 2 (databases)**  
✅ **No separate app needed**  
✅ **Deployed as part of existing homelab orchestration**

---

## Architecture

```
Homelab ArgoCD Root (wave 0)
    ↓
Wave 2: Databases App (syncs k8s/infra/databases)
    ├── authentik-db (ns: iam)
    ├── temporal-db (ns: temporal)
    └── memory-db (ns: poimen) ← NEW
         ├── Cluster: memory-db (3 instances)
         ├── Extension: pgvector (768-dim embeddings)
         ├── Secret: memory-db-app (auto-generated in poimen)
         └── Service: memory-db-rw (auto-generated in poimen)
```

## Deployment

### How It Works

Memory database is deployed **as part of homelab wave 2** (same wave as authentik-db and temporal-db):

1. **Homelab repository** contains the cluster definition
   - `k8s/infra/databases/memory-db.yaml` (deployed to: poimen namespace)
   - `k8s/infra/databases/kustomization.yaml` (includes memory-db.yaml)

2. **Homelab "databases" app** (wave 2) syncs these manifests
   - No separate poimen-memory app needed
   - Bundles all DB clusters in one wave
   - Simple and consistent

3. **Poimen Memory repo** contains reference copies
   - `k8s/infra/databases/memory-db.yaml` (for CI/documentation)
   - Deployed via homelab, not its own app

### Verification

```bash
# After homelab syncs wave 2:
kubectl get clusters -n poimen
# NAME        PHASE       INSTANCES
# memory-db   Healthy     3/3

kubectl get secret -n poimen memory-db-app
# memory-db-app    kubernetes.io/basic-auth   2

kubectl get svc -n poimen memory-db-rw
# memory-db-rw     ClusterIP   10.x.x.x   5432/TCP
```

---

## Connection String

```
postgresql://app:<password>@memory-db-rw.poimen.svc.cluster.local:5432/memory?sslmode=disable
```

**Credentials:** `kubectl get secret -n poimen memory-db-app`

## Deployment Checklist

- [x] Memory-db manifest in homelab k8s/infra/databases/
- [x] Namespace set to: poimen
- [x] Bundled into wave 2 (no separate app)
- [x] Homelab changes committed and pushed
- [x] Poimen Memory repo has reference copy

## What Changed

**Old approach (NOT USED):**
- ❌ Separate `poimen-memory-root` app in homelab
- ❌ Separate `memory-database-app.yaml`
- ❌ Separate k8s/argocd/ in Poimen Memory

**New approach (CURRENT):**
- ✅ Memory-db bundled into homelab wave 2 "databases" app
- ✅ Same pattern as authentik-db, temporal-db
- ✅ Poimen Memory repo has manifests (not ArgoCD apps)
- ✅ Simple, consistent, one deployment source

## Status

✅ **M2.2 CNPG Postgres** — Complete (bundled into homelab)  
✅ **Deployed by homelab wave 2** — No separate orchestration  
✅ **Ready for next phase** — Poimen app deployment (M3)
