+jina框架使用gPRC协议通讯，部署到k8s中对外暴露服务需要配置ingress注解。
+
+k3s中默认使用Traefik Ingress，参考yaml配置如下：
+
+
+```YAML
+
+---
+# Service
+apiVersion: v1
+kind: Service
+metadata:
+  name: grpc-demo
+  annotations:  
+    traefik.ingress.kubernetes.io/service.serversscheme: h2c
+spec:
+  ports:
+    - port: 8080
+  selector:
+    app.kubernetes.io/name: grpc-demo
+    app.kubernetes.io/instance: grpc-demo
+  type: ClusterIP
+
+
