### ⚠️ CRITICAL WARNING:
**DO NOT use `hostNetwork: true` with K3s svclb!**

K3s uses svclb (ServiceLB) for LoadBalancer services. If you add `hostNetwork: true`:
- Both svclb pods AND ingress-nginx pods will try to bind to ports 80/443
- This causes conflicts and connection failures
- svclb is already exposing ports correctly

See: `deployment/docs/INGRESS-NGINX-WARNING.md`

## 🔄 Backup Strategy

### Automatic Backup (CronJob):
- Runs daily at 2:00 AM
- Backs up: gitea, Foursat, Hosein databases
- Retention: 7 days
- Location: `/backups/` on mssql-pvc

### Manual Backup:
```bash
# Trigger manual backup
kubectl create job --from=cronjob/mssql-backup mssql-backup-manual-$(date +%s)

# Or apply the manual job
kubectl apply -f k8s-manifests/mssql-backup-cronjob.yaml
```

### Restore Database:
```bash
# Exec into MSSQL pod
kubectl exec -it deploy/mssql -- /bin/bash

# Restore
/opt/mssql-tools18/bin/sqlcmd -S localhost -U sa -P '87zH26nbqT' -C -Q "RESTORE DATABASE [Foursat] FROM DISK = '/backups/Foursat_YYYYMMDD_HHMMSS.bak' WITH REPLACE"
```

---

## 🚀 Deployment Commands

### Deploy All:
```bash
# Apply manifests
kubectl apply -f k8s-manifests/mssql-deployment.yaml
kubectl apply -f k8s-manifests/gitea-deployment.yaml
kubectl apply -f k8s-manifests/nexus-deployment.yaml
kubectl apply -f k8s-manifests/mssql-backup-cronjob.yaml
```

### Check Status:

## 🔐 Credentials Summary

| Service | Username | Password | Server |
|---------|----------|----------|--------|
| Staging SSH | root | 87zH26nbqT | 194.5.195.53 |
| Production SSH | root | 87zH26nbqT | 45.149.79.127 |
| Staging MSSQL | sa | 87zH26nbqT | mssql-svc:1433 |
| Production MSSQL | sa | YourStrong@Passw0rd | 45.149.79.127:31433 |
| Gitea | admin | (set during install) | 194.5.195.53 |

---

## 📋 Troubleshooting

### MSSQL Not Starting:
1. Check if volumeMounts exists in deployment
2. Verify password matches stored in database
3. Use single-user mode to reset password if needed

### Gitea Shows Install Page:
1. Check if volumeMounts exists (must mount to `/data`)
2. Verify MSSQL is running and accessible
3. Check `/data/gitea/conf/app.ini` for database config

### Images Not Pulling:
1. Ensure Nexus is running
2. For K3s, add to `/etc/rancher/k3s/registries.yaml`:
```yaml
mirrors:
  "194.5.195.53:32082":
    endpoint:
      - "http://194.5.195.53:32082"
```

## 🔧 CMS Ingress & Kestrel Protocol (بروز‌شده: February 2026)

### تنظیمات Kestrel:
| متغیر | مقدار قبلی | مقدار فعلی |
|--------|-----------|------------|
| `Kestrel__EndpointDefaults__Protocols` | `Http2` | `Http1AndHttp2` |

> با `Http1AndHttp2` هم gRPC (HTTP/2) و هم REST/HTTP (HTTP/1.1) روی یک پورت کار می‌کنن.

### تنظیمات Ingress CMS:
| Annotation | مقدار قبلی | مقدار فعلی |
|-----------|-----------|------------|
| `backend-protocol` | `GRPC` | حذف شد |
| `grpc-backend` | `true` | حذف شد |
| `ssl-redirect` | `true` | `true` |
| `cert-manager.io/cluster-issuer` | `letsencrypt-prod` | `letsencrypt-prod` |

> ⚠️ FrontOffice از gRPC-Web استفاده می‌کنه که روی HTTP/1.1 هم کار می‌کنه — نیازی به annotation GRPC نیست.

### NuGet Package (Proto):
| پکیج | نسخه | رجیستری |
|-------|-------|--------|
| `Foursat.CMSMicroservice.Protobuf` | `0.0.179` | Nexus (`foursat-nuget-hosted`) |

## 🚀 How It Works

### NuGet Package Workflow
1. **First restore:** `dotnet restore`
   - Downloads packages from nuget.org **via Nexus proxy**
   - Nexus caches packages locally
   
2. **Subsequent restores:**
   - Served from Nexus cache
   - **No internet required!** ✅

### Docker Image Workflow
1. **Build time:**
   ```dockerfile
   FROM 194.5.195.53:32500/dotnet/aspnet:9.0
   ```
   - Pulls from local Docker Registry
   - **No internet required!** ✅

2. **Runtime (Kubernetes):**
   ```yaml
   image: 194.5.195.53:32500/nginx:alpine
   ```
   - Pulls from local registry
   - **No internet required!** ✅

## 📊 Storage Usage

| Service | Storage Path | Size | Purpose |
|---------|--------------|------|---------|
| Docker Registry | `/var/lib/registry` | 881 MB | Cached Docker images |
| Nexus | `/var/lib/nexus` | ~700 MB | NuGet packages + metadata |
| Containerd | `/var/lib/containerd` | ~2.4 GB | K8s runtime images |

**Total offline assets:** ~4 GB

---

## 🔍 Verification Commands

### Check Docker Registry
```bash
# List images in registry
curl -s http://194.5.195.53:32500/v2/_catalog | python3 -m json.tool

# Check storage
ssh root@194.5.195.53 "du -sh /var/lib/registry"
```

### Check Nexus NuGet
```bash
# Test NuGet connectivity
dotnet nuget list source

# Test package download
dotnet add package Newtonsoft.Json
```

### Check Nexus UI
```bash
# Open in browser
https://nexus.se.kbs1.ir

# Login: admin / 87zH26nbqT
# Browse → docker-hosted (for future Docker images)
# Browse → nuget-org-proxy (for cached NuGet packages)
```

---

## 🛠️ Maintenance

### Add New Docker Image to Local Registry
```bash
# On server with internet (172.19.101.100)
docker pull <new-image>
docker save <new-image> -o /tmp/new-image.tar

# Transfer to main server
scp /tmp/new-image.tar root@194.5.195.53:/tmp/

# On main server (194.5.195.53)
ctr -n k8s.io images import /tmp/new-image.tar
ctr -n k8s.io images tag <new-image> 194.5.195.53:32500/<new-image>
ctr -n k8s.io images push --plain-http 194.5.195.53:32500/<new-image>
```

### Clear NuGet Cache (if needed)
```bash
# Via Nexus UI
Settings → Repository → Repositories → nuget-org-proxy → Repair - Invalidate cache

# Or delete and recreate repository
```

### Backup Cached Assets
```bash
# Docker Registry
tar -czf docker-registry-backup.tar.gz /var/lib/registry/

# Nexus
kubectl scale deployment nexus --replicas=0
tar -czf nexus-backup.tar.gz /var/lib/nexus/
kubectl scale deployment nexus --replicas=1
```
