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)

# 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:

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):

# 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):

# 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:

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:

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

Testing

# 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:

   sudo apt update
   sudo apt install -y docker.io docker-compose-v2
   sudo usermod -aG docker $USER  # logout/login required
   

2. Registry credentials:

   docker login registry.barodine.net
   # Username: <from founder>
   # Password: <from founder>
   

3. Firewall rules (if needed):

   sudo ufw allow 3000/tcp  # AgentHub port
   

Step 1: Prepare Environment

Create deployment directory:

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

Download compose.lan.yml from repository:

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

Create .env file:

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:

# 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:

docker compose -f compose.lan.yml pull

Start services:

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

First-time deployment: Run migrations and seed:

# 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:

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

Check logs:

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:

# 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

Step 4: Create First Agent

# 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:

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:

# 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:

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:

# 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:

# 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

Summary steps:

1. Push image to registry:

   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:

   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)

Post-Deployment Verification

Full checklist: POST-DEPLOY-VERIFICATION.md

Quick Verification (2 minutes)

# 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:

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:

   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:

   sudo lsof -i :3000
   # Kill conflicting process or change PORT in .env
   

/readyz returns 503

Symptom:

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

Debug:

# 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:

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:

   docker compose -f compose.lan.yml exec agenthub printenv FEATURE_MESSAGING_ENABLED
   # → true
   

2. CORS allowed:

   # Check agent's origin is in ALLOWED_ORIGINS
   docker compose -f compose.lan.yml exec agenthub printenv ALLOWED_ORIGINS
   

3. Firewall allows WebSocket upgrade:

   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:

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:

# 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:

   docker compose -f compose.lan.yml up -d postgres
   

6. Restore database:

   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:

   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)
