## 🚀 Deployment Paths

### Path 1: Quick Testing (Today)
```
Current State:
├─ ABDM credentials: ✅ Configured
├─ CSNOtk gateway: ✅ Ready to use
└─ OPD ABDM form: ✅ Ready to test

Action:
→ docs/ABDM_QUICK_START.md (7 steps)
→ Complete testing this week
```

### Path 2: Custom Gateway (Next Week)
```
Preparation:
├─ Provision Ubuntu server (DigitalOcean, AWS, etc)
├─ DNS: Create A record for abdm-bridge.e-atria.in
└─ Upload middleware-gateway/ folder

Deployment:
→ ssh root@server
→ cd /opt/middleware-gateway
→ sudo ./deploy.sh

Time: 15 minutes (fully automated)
```

### Path 3: Hybrid (Recommended)
```
Week 1: Use CSNOtk for testing
Week 2: Deploy custom gateway in parallel
Week 3: Switch HMS to new gateway
Week 4+: Production operations
```

---

## 🔧 Key Commands

### Deploy Custom Gateway
```bash
cd /opt/middleware-gateway
sudo ./deploy.sh
```

### Configure HMS
```bash
# Edit .env
BRIDGE_SYNC_URL = https://abdm-bridge.e-atria.in/api/v3

# Restart
docker-compose restart
```

### Test Gateway
```bash
curl https://abdm-bridge.e-atria.in/api/v3/health
```

### View Logs
```bash
docker logs -f abdm-bridge-gateway
```
