+
+راهنمای سریع برای deploy کردن Peikarband روی Kubernetes.
+
+## پیش‌نیاز
+
+- Kubernetes cluster (v1.24+)
+- Helm 3 نصب شده
+- kubectl پیکربندی شده
+- دسترسی به یک Container Registry
+
+## مراحل
+
+### 1. Clone Repository
+
+```bash
+git clone https://github.com/peikarband/landing.git
+cd landing
+```
+
+### 2. Build Docker Image
+
+```bash
+# تغییر REGISTRY به registry خودتون
+export REGISTRY=registry.example.com
+export IMAGE_NAME=peikarband/landing
+export VERSION=0.1.0
+
+docker build -t ${REGISTRY}/${IMAGE_NAME}:${VERSION} .
+docker push ${REGISTRY}/${IMAGE_NAME}:${VERSION}
+```
+
+### 3. ساخت Secrets
+
+```bash
+kubectl create namespace production
+
+kubectl create secret generic peikarband-secrets \
+  --from-literal=db-username=peikarband \
+  --from-literal=db-password=YOUR_STRONG_PASSWORD \
+  --from-literal=redis-password=YOUR_REDIS_PASSWORD \
+  -n production
+```
+
+### 4. Deploy با Helm
+
+```bash
+helm upgrade --install peikarband ./helm/peikarband \
+  --namespace production \
+  --set image.repository=${REGISTRY}/${IMAGE_NAME} \
+  --set image.tag=${VERSION} \
+  --set ingress.hosts[0].host=yourdomain.com \
+  --wait
+```
+
+### 5. چک کردن وضعیت
+
+```bash
+# Pods
+kubectl get pods -n production
+
+# Service
+kubectl get svc -n production
+
+# Ingress
+kubectl get ingress -n production
+```
+
+### 6. دسترسی به Application
+
+```bash
+# Port forward برای تست
+kubectl port-forward svc/peikarband 3000:3000 -n production
+
+# باز کردن در browser
+open http://localhost:3000
+```
+
+## پیکربندی Production
+
+برای production از `values-production.yaml` استفاده کنید:
+
+```bash
+helm upgrade --install peikarband ./helm/peikarband \
+  --namespace production \
+  --set image.repository=${REGISTRY}/${IMAGE_NAME} \
+  --set image.tag=${VERSION} \
+  --values helm/peikarband/values-production.yaml \
+  --wait
+```
+
+## Uninstall
+
+```bash
+helm uninstall peikarband -n production
+kubectl delete namespace production
+```
