+# TiDB Deployment on Kubernetes
+
+[TiDB Operator](https://github.com/pingcap/tidb-operator) manages TiDB clusters on [Kubernetes](https://kubernetes.io) 
+and automates tasks related to operating a TiDB cluster. It makes TiDB a truly cloud-native database.
+
+> **Warning:** Currently, TiDB Operator is work in progress [WIP] and is NOT ready for production. Use at your own risk.
+
+## Google Kubernetes Engine (GKE)
+
+The TiDB Operator tutorial for GKE runs directly in the Google Cloud Shell.

+
+## Local install using Docker in Docker
+
+Docker in Docker (DinD) runs Docker containers as virtual machines and runs another layer of Docker containers inside the first layer of Docker containers. `kubeadm-dind-cluster` uses this technology to run the Kubernetes cluster in Docker containers. TiDB Operator uses a modified DinD script to manage the DinD Kubernetes cluster.
