+# Deploy Kyuubi On Kubernetes
+
+## Requirements
+
+If you want to deploy Kyuubi on Kubernetes, you'd better get a sense of the following things.
+
+* Use Kyuubi official docker image or build Kyuubi docker image
+* An active Kubernetes cluster
+* Reading About [Deploy Kyuubi engines on Kubernetes](engine_on_kubernetes.md)
+* [Kubectl](https://kubernetes.io/docs/reference/kubectl/overview/)
+* KubeConfig of the target cluster
+
+## Kyuubi Official Docker Image 
+
+You can find the official docker image at [Apache Kyuubi (Incubating) Docker Hub](https://registry.hub.docker.com/r/apache/kyuubi).
+
+## Build Kyuubi Docker Image
+
+You can build custom Docker images from the `${KYUUBI_HOME}/bin/docker-image-tool.sh` contained in the binary package.
+
+Examples:
+```shell
+  - Build and push image with tag "v1.4.0" to docker.io/myrepo
+    $0 -r docker.io/myrepo -t v1.4.0 build
+    $0 -r docker.io/myrepo -t v1.4.0 push
+
+  - Build and push with tag "v3.0.0" and Spark-3.1.2 as base image to docker.io/myrepo
+    $0 -r docker.io/myrepo -t v3.0.0 -b BASE_IMAGE=repo/spark:3.1.2 build
+    $0 -r docker.io/myrepo -t v3.0.0 push
+
+  - Build and push for multiple archs to docker.io/myrepo
+    $0 -r docker.io/myrepo -t v3.0.0 -X build
+
+  - Build with Spark placed "/path/spark"
+    $0 -s /path/spark build
+```
+
+`${KYUUBI_HOME}/bin/docker-image-tool.sh` use `Kyuubi Version` as default docker tag and always build `${repo}/kyuubi:${tag}` image.
+
+The script can also help build external Spark into a Kyuubi image that acts as a client for submitting tasks by `-s ${SPAAK_HOME}`.
+
+## Deploy
+
+Multiple YAML files are provided under `${KYUUBI_HOME}/docker/` to help you deploy Kyuubi.
+
+You can deploy single-node Kyuubi through `${KYUUBI_HOME}/docker/kyuubi-pod.yaml` or `${KYUUBI_HOME}/docker/kyuubi-deployment.yaml`.
+
+Also, you can use `${KYUUBI_HOME}/docker/kyuubi-service.yaml` to deploy Kyuubi Service.
+
+## Config
+
+You can configure Kyuubi the old-fashioned way by placing kyuubi-default.conf inside the image. Kyuubi do not recommend using this way on Kubernetes.
+
+Kyuubi provide `${KYUUBI_HOME}/docker/kyuubi-configmap.yaml` to build Configmap for Kyuubi.
+
+You can find out how to use it in the comments inside the above file.
+
+If you want to know kyuubi engine on kubernetes configurations, you can refer to [Deploy Kyuubi engines on Kubernetes](engine_on_kubernetes.md)
+
+## Connect
+
+If you do not use Service or HostNetwork to get the IP address of the node where Kyuubi deployed.
+You should connect like:
+```shell
+kubectl exec -it kyuubi-example -- /bin/bash
+${SPARK_HOME}/bin/beeline -u 'jdbc:hive2://localhost:10009'
+```
+
+Or you can submit tasks directly through local beeline:
+```shell
+${SPARK_HOME}/bin/beeline -u 'jdbc:hive2://${hostname}:${port}'
+```
+As using service nodePort, port means nodePort and hostname means any hostname of kubernetes node.
+
+As using HostNetwork, port means kyuubi containerPort and hostname means hostname of node where Kyuubi deployed.
+
+## TODO 
+Kyuubi will provide other connection methods in the future, like `Ingress`, `Load Balance`.
