🚀 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

cd /opt/middleware-gateway
sudo ./deploy.sh

Configure HMS

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

# Restart
docker-compose restart

Test Gateway

curl https://abdm-bridge.e-atria.in/api/v3/health

View Logs

docker logs -f abdm-bridge-gateway
