# Deploy Phase 2 from Nginx Proxy Host

## Quick Start

**You need to SSH to the proxy host first. The proxy may use a different SSH key.**

### Step 1: SSH to Nginx Proxy

```bash
# Try with different keys if available:
ssh besuadmin@20.160.58.99

# Or with a specific key:
ssh -i /path/to/proxy/key besuadmin@20.160.58.99
```

### Step 2: Copy Project Files to Proxy (if needed)

**From your local machine**, after SSH access is working:

```bash
cd /home/intlc/projects/smom-dbis-138

# Copy project to proxy (adjust key path as needed)
rsync -avz -e "ssh -i /path/to/proxy/key" \
  --exclude '.git' \
  --exclude '.terraform' \
  --exclude '*.tfstate*' \
  --exclude '.terraform.lock.hcl' \
  --exclude 'terraform.tfvars' \
  --exclude 'node_modules' \
  --exclude '__pycache__' \
  --exclude '*.pyc' \
  --progress \
  ./ \
  besuadmin@20.160.58.99:~/smom-dbis-138/
```

### Step 3: Deploy from Proxy Host

**On the proxy host (20.160.58.99):**

```bash
# Navigate to project
cd ~/smom-dbis-138

# Load environment variables
source .env

# Verify SSH key path is correct for accessing VMs
ls -la keys/besuadmin-us-nodes_key.pem

# Ensure key has correct permissions
chmod 600 keys/besuadmin-us-nodes_key.pem

# Generate Phase 2 configuration (reads Phase 1 outputs)
cd terraform/phases/phase1
terraform output -json phase1_us_regions > /tmp/phase1_outputs.json

cd ../phase2

# Generate terraform.tfvars
../../scripts/deployment/generate-phase2-tfvars.sh

# Review configuration
cat terraform.tfvars

# Initialize Terraform
terraform init -upgrade

# Plan deployment
terraform plan

# Deploy to all 5 regions (parallel)
terraform apply -auto-approve
```

### Step 4: Start Services

**On the proxy host:**

```bash
cd ~/smom-dbis-138

# Start all services in parallel across all regions
./terraform/phases/phase2/scripts/start-services.sh all
```

### Step 5: Verify Deployment

**On the proxy host:**

```bash
cd ~/smom-dbis-138

# Check status of all regions in parallel
./terraform/phases/phase2/scripts/status.sh all
```

## Alternative: Use Convenience Script

**On the proxy host:**

```bash
cd ~/smom-dbis-138
source .env
./scripts/deployment/deploy-phase2-from-proxy.sh
```

## Troubleshooting

### SSH Key Issues

If the proxy uses a different SSH key:

1. Check if you have the proxy key:
   ```bash
   ls -la ~/.ssh/ | grep -E "(proxy|bastion|nginx)"
   ```

2. Try connecting with different keys:
   ```bash
   ssh -i ~/.ssh/id_rsa besuadmin@20.160.58.99
   ssh -i ~/.ssh/id_ed25519 besuadmin@20.160.58.99
   ```

3. Check SSH config:
   ```bash
   cat ~/.ssh/config | grep -A 10 "20.160.58.99"
   ```

### Verify VM Connectivity from Proxy

**On the proxy host**, test SSH to VMs:

```bash
# Test each VM
for ip in 10.1.1.4 10.2.1.4 10.3.1.4 10.4.1.4 10.5.1.4; do
  echo "Testing $ip..."
  ssh -i ~/smom-dbis-138/keys/besuadmin-us-nodes_key.pem \
      -o StrictHostKeyChecking=no \
      besuadmin@$ip "echo '✅ $ip: OK'"
done
```

### Terraform Issues

If Terraform can't connect to VMs:

1. Check SSH key path in `.env`:
   ```bash
   grep SSH_PRIVATE_KEY_PATH .env
   ```

2. Verify key permissions:
   ```bash
   chmod 600 keys/besuadmin-us-nodes_key.pem
   ```

3. Test SSH manually:
   ```bash
   ssh -i keys/besuadmin-us-nodes_key.pem besuadmin@10.3.1.4
   ```

## Complete Deployment Command Sequence

**Copy and run on proxy host:**

```bash
cd ~/smom-dbis-138
source .env
chmod 600 keys/besuadmin-us-nodes_key.pem
cd terraform/phases/phase2
terraform init -upgrade
terraform apply -auto-approve
cd ~/smom-dbis-138
./terraform/phases/phase2/scripts/start-services.sh all
./terraform/phases/phase2/scripts/status.sh all
```
