+### Launch Paddle Serving on Kubernetes
+
+Paddle Serving support deployment on Kubernetes (K8S) clusters. From `imagenet_k8s_rpc.yaml` we define Serving as K8S Deployment and Service. User can deploy Serving on containers and expose internal or external service.
+
+We strongly recommend [Baidu Cloud CCE Cluster](https://cloud.baidu.com/search.html?q=CCE)
+
+```
+kubectl apply -f imagenet_k8s_rpc.yaml

+
+### K8S启动
+
+还可以运用K8S启动，在`imagenet_k8s_rpc.yaml`中定义了Serving的Deployment和Service，用户可以在K8S集群上启动Deployment并且通过Service对外暴露服务，用户可以在此基础上进行二次开发。
+
+推荐百度云的[CCE（K8S）集群](https://cloud.baidu.com/search.html?q=CCE)
