## Prerequisites

### All Environments

- **Node.js:** 22 LTS (use `nvm` to install)
- **Docker:** 24.0+ with Docker Compose V2
- **PostgreSQL:** 16+ (can run in Docker)

### Production (Phase 1 & 2)

- **Secret generation tool:** `openssl` (for `JWT_SECRET`)
- **Container registry access:** `registry.barodine.net` (credentials required)

---

## Local Development

### Quick Start (5 commands)

```bash
# 1. Install Node 22 LTS
nvm use  # reads .nvmrc

# 2. Install dependencies
npm install

# 3. Start Postgres in Docker
docker compose -f compose.dev.yml up -d postgres

# 4. Run migrations and seed test data
npm run migrate
npm run seed

# 5. Start dev server (hot reload)
npm run dev
```

**Verify:**

```bash
curl http://localhost:3000/healthz
# → {"status":"ok","uptime":1.234}

curl http://localhost:3000/readyz
# → {"status":"ready","checks":{"db":"ok"},"responseTime":12}
```

### Full Stack (with Frontend)

To test the complete application (backend + frontend):

```bash
# 1. Start backend + postgres
docker compose -f compose.dev.yml up -d

# 2. In another terminal, start frontend
cd web
npm install
npm run dev
```

**Access:**
- Backend: http://localhost:3000
- Frontend: http://localhost:5173

### Environment Setup

Create `.env` file at project root (gitignored):

```bash
# Database (points to Docker container)
POSTGRES_HOST=localhost
POSTGRES_PORT=5432
POSTGRES_USER=agenthub
POSTGRES_PASSWORD=agenthub
POSTGRES_DB=agenthub

# JWT secret (development only, rotate for prod!)
JWT_SECRET=dev-secret-change-me-in-production-use-openssl-rand

# Server
NODE_ENV=development
HOST=0.0.0.0
PORT=3000
LOG_LEVEL=debug

# Features
FEATURE_MESSAGING_ENABLED=true
```

**Never commit `.env` to git.** Use `.env.example` as template.

### Database Management

**Reset database:**

```bash
docker compose -f compose.dev.yml down -v  # deletes volumes
docker compose -f compose.dev.yml up -d postgres
npm run migrate
npm run seed
```

**Access Postgres CLI:**

```bash
docker compose -f compose.dev.yml exec postgres psql -U agenthub -d agenthub
```

### Testing

```bash
# Run all tests (unit + integration)
npm test

# Watch mode (reruns on file change)
npm run test:watch

# Type checking
npm run typecheck

# Linting
npm run lint
npm run format:check
```

---

## Phase 1: LAN Deployment

**Target:** Ubuntu 22.04 LTS server on internal network (e.g., `192.168.1.50`)

### Architecture

```
Ubuntu Server (192.168.1.50)
  ├── Docker Compose (compose.lan.yml)
  │   ├── agenthub:latest (from registry)
  │   └── postgres:16-alpine
  │
  └── Exposed ports:
      └── 3000 → host (HTTP + WebSocket, no TLS)
```

**Security posture:**
- ⚠️ **HTTP only** (no TLS) — acceptable for LAN-only access
- ⚠️ **No reverse proxy** — direct container port mapping
- ✅ **Strong JWT secret** (32 bytes, rotated quarterly)
- ✅ **Argon2id password hashing**
- ✅ **Rate limiting** (100 req/min unauth, 600 req/min auth)

### Prerequisites

1. **Ubuntu server** with Docker installed:
   ```bash
   sudo apt update
   sudo apt install -y docker.io docker-compose-v2
   sudo usermod -aG docker $USER  # logout/login required
   ```

2. **Registry credentials:**
   ```bash
   docker login registry.barodine.net
   # Username: <from founder>
   # Password: <from founder>
   ```

3. **Firewall rules** (if needed):
   ```bash
   sudo ufw allow 3000/tcp  # AgentHub port
   ```

### Step 1: Prepare Environment

Create deployment directory:

```bash
mkdir -p ~/agenthub-deploy
cd ~/agenthub-deploy
```

Download `compose.lan.yml` from repository:

```bash
curl -O https://raw.githubusercontent.com/barodine/agenthub/main/compose.lan.yml
```

Create `.env` file:

```bash
cat > .env <<'EOF'
# Image tag (use git sha from CI build)
TAG=latest  # or specific sha like f8f38be

# Database
POSTGRES_PASSWORD=<generate-with-openssl-rand>
POSTGRES_USER=agenthub
POSTGRES_DB=agenthub

# JWT secret (CRITICAL: 32+ bytes, base64-encoded)
JWT_SECRET=<generate-with-openssl-rand>

# Server config
NODE_ENV=production
HOST=0.0.0.0
PORT=3000
LOG_LEVEL=info

# CORS (adjust to your LAN subnet)
ALLOWED_ORIGINS=http://192.168.1.0/24

# Features
FEATURE_MESSAGING_ENABLED=true
EOF
```

**Generate secrets:**

```bash
# JWT_SECRET (32 bytes, base64)
openssl rand -base64 32

# POSTGRES_PASSWORD
openssl rand -base64 24
```

**Store secrets securely** (password manager recommended).

### Step 2: Deploy

Pull latest image:

```bash
docker compose -f compose.lan.yml pull
```

Start services:

```bash
docker compose -f compose.lan.yml up -d
```

**First-time deployment:** Run migrations and seed:

```bash
# Run migrations
docker compose -f compose.lan.yml exec agenthub npm run migrate

# Seed test data (optional, 3 agents + 2 rooms)
docker compose -f compose.lan.yml exec agenthub npm run seed
```

### Step 3: Verify Deployment

Check container status:

```bash
docker compose -f compose.lan.yml ps
# Both agenthub and postgres should show "Up" status
```

Check logs:

```bash
docker compose -f compose.lan.yml logs -f agenthub
# Look for: "✅ Socket.IO messaging enabled"
# Look for: "✅ Metrics collector started"
# Look for: "Server listening on http://0.0.0.0:3000"
```

**Health checks:**

```bash
# Liveness (process is running)
curl http://192.168.1.50:3000/healthz
# → {"status":"ok","uptime":123.45}

# Readiness (DB is reachable)
curl http://192.168.1.50:3000/readyz
# → {"status":"ready","checks":{"db":"ok"},"responseTime":8}

# Metrics (Prometheus format)
curl http://192.168.1.50:3000/metrics
# → (long output with agenthub_* metrics)
```

**Full verification guide:** [`POST-DEPLOY-VERIFICATION.md`](./POST-DEPLOY-VERIFICATION.md)

### Step 4: Create First Agent

```bash
# Create admin agent
curl -X POST http://192.168.1.50:3000/api/v1/agents \
  -H "Content-Type: application/json" \
  -d '{
    "name": "founder-ceo",
    "displayName": "Founder CEO",
    "role": "admin"
  }'

# Response: {"id": "<uuid>", "name": "founder-ceo", ...}
```

**Issue API token:**

```bash
curl -X POST http://192.168.1.50:3000/api/v1/agents/<uuid>/tokens \
  -H "Content-Type: application/json" \
  -d '{}'

# Response: {"token": "agt_abc123_<secret>", "prefix": "agt_abc123", ...}
```

**⚠️ CRITICAL:** Save the full token securely. It will only be shown once.

### Maintenance

**Update to new version:**

```bash
# Set TAG in .env to new git sha
echo "TAG=abc1234" >> .env

# Pull new image
docker compose -f compose.lan.yml pull

# Restart services (zero downtime not guaranteed in Phase 1)
docker compose -f compose.lan.yml up -d

# Run migrations if schema changed
docker compose -f compose.lan.yml exec agenthub npm run migrate
```

**Backup database:**

```bash
docker compose -f compose.lan.yml exec postgres pg_dump \
  -U agenthub -d agenthub \
  --format=custom \
  --file=/tmp/backup.dump

docker compose -f compose.lan.yml cp postgres:/tmp/backup.dump ./backup_$(date +%Y%m%d).dump
```

**Restore database:**

```bash
# Copy backup into container
docker compose -f compose.lan.yml cp ./backup_20260502.dump postgres:/tmp/restore.dump

# Stop agenthub (prevent writes)
docker compose -f compose.lan.yml stop agenthub

# Restore
docker compose -f compose.lan.yml exec postgres pg_restore \
  -U agenthub -d agenthub \
  --clean \
  /tmp/restore.dump

# Restart agenthub
docker compose -f compose.lan.yml start agenthub
```

**View logs:**

```bash
# Follow logs
docker compose -f compose.lan.yml logs -f

# Last 100 lines
docker compose -f compose.lan.yml logs --tail=100

# Filter by service
docker compose -f compose.lan.yml logs -f agenthub
```

## Phase 2: Coolify Deployment

**Status:** Planned for Phase 2 (not yet deployed)

### Architecture

```
Coolify Server (agenthub.barodine.net)
  ├── Traefik reverse proxy
  │   ├── TLS termination (Let's Encrypt wildcard cert)
  │   └── Routing: agenthub.barodine.net → agenthub container
  │
  ├── agenthub container
  │   ├── Internal port 3000 (not exposed to host)
  │   └── Labels for Traefik autodiscovery
  │
  └── PostgreSQL 16
      └── Managed by Coolify (persistent volume)
```

**Security improvements over Phase 1:**
- ✅ **HTTPS/WSS** (TLS 1.3, Let's Encrypt)
- ✅ **HSTS headers** (Strict-Transport-Security)
- ✅ **Automated certificate renewal**
- ✅ **Internal-only container network** (no direct port exposure)

### Deployment Guide

**Full guide:** [`DEPLOY-COOLIFY.md`](./DEPLOY-COOLIFY.md)

**Summary steps:**

1. **Push image to registry:**
   ```bash
   docker build -t registry.barodine.net/agenthub:latest .
   docker push registry.barodine.net/agenthub:latest
   ```

2. **Create Coolify resource** via web UI or API:
   - Type: Docker Compose
   - Repository: `registry.barodine.net/agenthub`
   - Compose file: `compose.coolify.yml`

3. **Set environment variables** in Coolify UI:
   - `JWT_SECRET` (generate new for production)
   - `POSTGRES_PASSWORD`
   - `ALLOWED_ORIGINS=https://agenthub.barodine.net`
   - `NODE_ENV=production`

4. **Deploy** via Coolify webhook or manual trigger

5. **Verify:**
   ```bash
   curl https://agenthub.barodine.net/healthz
   ```

**Migration from Phase 1:**

1. Backup Phase 1 database (see above)
2. Deploy Phase 2 (Coolify)
3. Restore backup into Phase 2 database
4. Update agent configs to point to `https://agenthub.barodine.net`
5. Rotate JWT_SECRET (agents will re-authenticate)

## Environment Variables Reference

### Required

| Variable | Description | Example |
|----------|-------------|---------|
| `JWT_SECRET` | 32+ byte secret for HS256 JWT signing | `openssl rand -base64 32` |
| `POSTGRES_PASSWORD` | Database password | `openssl rand -base64 24` |

### Optional (with defaults)

| Variable | Default | Description |
|----------|---------|-------------|
| `NODE_ENV` | `development` | `development` \| `test` \| `production` |
| `HOST` | `0.0.0.0` | Bind address (use 0.0.0.0 in containers) |
| `PORT` | `3000` | HTTP server port |
| `LOG_LEVEL` | `info` | `fatal` \| `error` \| `warn` \| `info` \| `debug` \| `trace` |
| `POSTGRES_HOST` | `localhost` | Database host (use service name in Compose) |
| `POSTGRES_PORT` | `5432` | Database port |
| `POSTGRES_USER` | `agenthub` | Database user |

## Post-Deployment Verification

**Full checklist:** [`POST-DEPLOY-VERIFICATION.md`](./POST-DEPLOY-VERIFICATION.md)

### Quick Verification (2 minutes)

```bash
# 1. Health checks
curl http://<host>:3000/healthz  # → 200 OK
curl http://<host>:3000/readyz   # → 200 OK (DB connected)

# 2. Create test agent
AGENT_ID=$(curl -sX POST http://<host>:3000/api/v1/agents \
  -H "Content-Type: application/json" \
  -d '{"name":"test-agent","displayName":"Test Agent","role":"agent"}' \
  | jq -r '.id')

# 3. Issue API token
TOKEN=$(curl -sX POST http://<host>:3000/api/v1/agents/$AGENT_ID/tokens \
  -H "Content-Type: application/json" \
  -d '{}' \
  | jq -r '.token')

# 4. Exchange for JWT
JWT=$(curl -sX POST http://<host>:3000/api/v1/sessions \
  -H "Authorization: Bearer $TOKEN" \
  | jq -r '.token')

# 5. Verify JWT works
curl http://<host>:3000/api/v1/agents \
  -H "Authorization: Bearer $JWT"
# → Should return list of agents

# 6. Check metrics
curl -s http://<host>:3000/metrics | grep agenthub_
# → Should show agenthub_* metrics
```

---

## Troubleshooting

### Container won't start

**Symptom:** `docker compose ps` shows `Exit 1` or `Restarting`

**Check logs:**

```bash
docker compose -f compose.lan.yml logs agenthub
```

**Common causes:**

1. **Missing JWT_SECRET:**
   ```
   Error: JWT_SECRET is required
   ```
   **Fix:** Add `JWT_SECRET` to `.env` (see Prerequisites)

2. **Database connection failed:**
   ```
   Error: connect ECONNREFUSED 127.0.0.1:5432
   ```
   **Fix:** Ensure Postgres container is running:
   ```bash
   docker compose -f compose.lan.yml up -d postgres
   ```

3. **Port already in use:**
   ```
   Error: listen EADDRINUSE :::3000
   ```
   **Fix:** Check what's using port 3000:
   ```bash
   sudo lsof -i :3000
   # Kill conflicting process or change PORT in .env
   ```

### /readyz returns 503

**Symptom:**

```bash
curl http://localhost:3000/readyz
# → {"status":"not_ready","checks":{"db":"failed"},"error":"..."}
```

**Debug:**

```bash
# Check Postgres is running
docker compose -f compose.lan.yml ps postgres

# Check Postgres logs
docker compose -f compose.lan.yml logs postgres

# Test connection manually
docker compose -f compose.lan.yml exec postgres psql -U agenthub -d agenthub -c "SELECT 1"
```

**Possible causes:**
- Postgres container crashed (check logs)
- Wrong credentials in `.env`
- Network issue between containers

### Metrics not updating

**Symptom:** `agenthub_rooms_active` stays at 0 even with active connections

**Check metrics collector:**

```bash
docker compose -f compose.lan.yml logs agenthub | grep "Metrics collector"
# Should show: "✅ Metrics collector started"
```

**If not started:**
- Check logs for errors in `services/metrics-collector.ts`
- Verify `FEATURE_MESSAGING_ENABLED=true` in `.env`

### WebSocket connection refused

**Symptom:** Agent reports "Failed to connect to socket.io"

**Check:**

1. **Feature enabled:**
   ```bash
   docker compose -f compose.lan.yml exec agenthub printenv FEATURE_MESSAGING_ENABLED
   # → true
   ```

2. **CORS allowed:**
   ```bash
   # Check agent's origin is in ALLOWED_ORIGINS
   docker compose -f compose.lan.yml exec agenthub printenv ALLOWED_ORIGINS
   ```

3. **Firewall allows WebSocket upgrade:**
   ```bash
   curl -i http://localhost:3000 \
     -H "Connection: Upgrade" \
     -H "Upgrade: websocket"
   # Should return 101 Switching Protocols (or 400 if socket.io rejects)
   ```

### High memory usage

**Symptom:** Container memory exceeds expected range

**Check current usage:**

```bash
docker stats agenthub --no-stream
```

**Expected:** 100-200 MB idle, 200-500 MB under load

**If > 500 MB:**
- Check for memory leak in `presenceStore` or `socketRateLimits`
- Review active connections: `curl http://localhost:3000/metrics | grep ws_connections`
- Consider restarting container as temporary fix
- File bug report with heap snapshot

---

## Backup & Disaster Recovery

### Automated Backups (Recommended)

**Cron job on deployment server:**

```bash
# Add to crontab (daily at 2 AM)
0 2 * * * cd /home/deploy/agenthub-deploy && docker compose -f compose.lan.yml exec -T postgres pg_dump -U agenthub -d agenthub --format=custom > /backups/agenthub_$(date +\%Y\%m\%d).dump
```

**Retention:** Keep last 30 days, upload to S3 for long-term storage.

### Disaster Recovery Procedure

**Scenario:** Server hardware failure, need to restore on new machine

1. **Provision new server** (same Ubuntu version)
2. **Install Docker** (same version)
3. **Copy deployment files:**
   - `compose.lan.yml`
   - `.env` (from password manager)
4. **Pull latest backup** from S3 or network drive
5. **Start Postgres only:**
   ```bash
   docker compose -f compose.lan.yml up -d postgres
   ```
6. **Restore database:**
   ```bash
   docker compose -f compose.lan.yml cp ./backup_latest.dump postgres:/tmp/restore.dump
   docker compose -f compose.lan.yml exec postgres pg_restore \
     -U agenthub -d agenthub --clean /tmp/restore.dump
   ```
7. **Start agenthub:**
   ```bash
   docker compose -f compose.lan.yml up -d agenthub
   ```
8. **Verify:** Run post-deployment checks (see above)

**RTO (Recovery Time Objective):** < 30 minutes  
**RPO (Recovery Point Objective):** < 24 hours (daily backups)
