# Phase 1: Setup Complete ✅

## 🎉 All Automated Steps Completed Successfully!

### ✅ Infrastructure Deployment
- **104 resources** deployed and verified
- **6 VMs** running (5 backend + 1 Nginx proxy)
- All networking, storage, monitoring, and security resources configured

### ✅ Nginx Configuration
- Backend IPs configured: 5 backend VMs
- Nginx service running
- Health endpoint working: `http://localhost/health` → "healthy"

### ✅ Cloudflare Tunnel Setup
- **Tunnel Created**: `phase1-nginx-proxy`
- **Tunnel ID**: `fdb4c3df-0112-4404-9dd6-06039dc3f114`
- **Service**: Active and running
- **Connections**: Active to Cloudflare edge (ams13, ams15, ams18, ams20)
- **DNS**: Updated to point to tunnel
- **Endpoint**: `https://rpc.d-bis.org/health` → **"healthy"** ✅

### ✅ Domain Configuration
- Domain: `rpc.d-bis.org` (from `CLOUDFLARE_DOMAIN` in .env)
- DNS: Points to Cloudflare Tunnel
- SSL/TLS: Automatic via Cloudflare
- Proxy: Enabled (orange cloud)

## 📊 Current Status

### Infrastructure ✅
- All resources deployed
- All VMs running
- Network configured

### Services ✅
- Nginx: Running, backend configured
- Cloudflared: Running, tunnel active
- Domain: `rpc.d-bis.org` accessible via HTTPS

### Connectivity ✅
- Public → Cloudflare Tunnel → Nginx → Backend VMs (configured)
- Endpoint: `https://rpc.d-bis.org/health` working

## ⏳ Remaining Manual Steps

### Step 1: Besu Node Configuration
**Status**: Requires VPN/Bastion access

**Backend VMs:**
- Central US: `ssh besuadmin@10.3.1.4`
- East US: `ssh besuadmin@10.1.1.4`
- East US 2: `ssh besuadmin@10.4.1.4`
- West US: `ssh besuadmin@10.2.1.4`
- West US 2: `ssh besuadmin@10.5.1.4`

**For each VM:**
```bash
# Via VPN/Bastion
ssh besuadmin@<backend-vm-ip>
wget https://raw.githubusercontent.com/your-repo/terraform/phases/phase1/scripts/setup-besu-node.sh
chmod +x setup-besu-node.sh
sudo ./setup-besu-node.sh besu-node 0 <region>
```

**Verify:**
```bash
sudo systemctl status besu.service
curl http://localhost:8545
curl http://localhost:9545/metrics
```

### Step 2: Cross-Region Connectivity
**Status**: Optional (for Nginx to reach backend VMs)

**Options:**
1. **VPN/ExpressRoute** (recommended for production)
2. **Cloudflare Tunnel on each backend VM** (alternative)
3. **Azure Private Link** (for Azure-native solution)

## 🎯 Verification

### Test Endpoints
```bash
# Health check
curl https://rpc.d-bis.org/health
# Should return: "healthy"

# RPC endpoint (after Besu is configured)
curl -X POST https://rpc.d-bis.org/rpc \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'
```

### Check Services
```bash
# SSH to Nginx proxy
ssh besuadmin@20.160.58.99

# Check Cloudflare Tunnel
sudo systemctl status cloudflared
sudo cloudflared tunnel info phase1-nginx-proxy

# Check Nginx
sudo systemctl status nginx
curl http://localhost/health
```

## 📋 Summary

### ✅ Completed
- Infrastructure deployed (104 resources)
- Nginx configured with backend IPs
- Cloudflare Tunnel running and connected
- DNS configured and working
- SSL/TLS automatic via Cloudflare
- Public endpoint accessible: `https://rpc.d-bis.org/health`

### ⏳ Pending
- Besu node configuration (requires VPN/Bastion)
- Cross-region connectivity (optional)

## 🚀 Next Steps

1. **Configure Besu Nodes** (via VPN/Bastion):
   - SSH to each backend VM
   - Run setup script
   - Verify Besu is running

2. **Test RPC Endpoints**:
   - Once Besu is running, test RPC calls
   - Verify WebSocket connections
   - Check metrics endpoints

3. **Monitor**:
   - Check Cloudflare Tunnel logs
   - Monitor Nginx access logs
   - Verify backend connectivity

---

**Status**: ✅ **Cloudflare Tunnel setup complete! Endpoint is accessible at `https://rpc.d-bis.org/health`**

**Next**: Configure Besu nodes on backend VMs to complete the RPC setup.
