```

## Prerequisites

- Kubernetes cluster 1.24+
- kubectl configured
- Docker images built and pushed to registry
- Secrets configured (see secrets.yaml.example)

## Deployment Steps

### 1. Create Namespace

```bash
kubectl apply -f k8s/namespace.yaml
```

### 2. Create Secrets

```bash
# Copy example and fill in real values
cp k8s/secrets.yaml.example k8s/secrets.yaml
# Edit secrets.yaml with real values
kubectl create secret generic veza-secrets \
  --from-env-file=k8s/secrets.yaml \
  -n veza-production
```

### 3. Create ConfigMap

```bash
kubectl apply -f k8s/configmap.yaml
```

### 4. Deploy Services

```bash
# Backend API
kubectl apply -f k8s/backend-api/

# Frontend
kubectl apply -f k8s/frontend/

# Chat Server
kubectl apply -f k8s/chat-server/

# Stream Server (if separate)
kubectl apply -f veza-stream-server/k8s/production/
```

### 5. Create Ingress

```bash
kubectl apply -f k8s/ingress.yaml
```

## Verification

```bash
# Check pods
kubectl get pods -n veza-production

# Check services
kubectl get svc -n veza-production

# Check ingress
kubectl get ingress -n veza-production

# View logs
kubectl logs -f deployment/veza-backend-api -n veza-production
```

## Scaling

```bash
# Scale backend API
kubectl scale deployment veza-backend-api --replicas=5 -n veza-production

# Scale frontend
kubectl scale deployment veza-frontend --replicas=3 -n veza-production
```

## Updates

```bash
# Update image
kubectl set image deployment/veza-backend-api \
  backend-api=veza-backend-api:v1.1.0 \
  -n veza-production

# Rollout status
kubectl rollout status deployment/veza-backend-api -n veza-production
```

## Troubleshooting

```bash
# Describe pod
kubectl describe pod <pod-name> -n veza-production

# Get events
kubectl get events -n veza-production --sort-by='.lastTimestamp'

# Port forward for debugging
kubectl port-forward deployment/veza-backend-api 8080:8080 -n veza-production
```
