+# Use Rainbond Deployment
+
+This section describes the one-click deployment of high availability DolphinScheduler clusters through the [Rainbond](https://www.rainbond.com/) cloud native application management platform. This method is suitable for users who don't know much about complex technologies such as `Kubernetes`, lowering the threshold for deploying DolphinScheduler in `Kubernetes` mode.
+
+## Prerequisites
+
+* Available Rainbond cloud native application management platform is a prerequisite，please refer to the official `Rainbond` documentation [Rainbond Quick install](https://www.rainbond.com/docs/quick-start/quick-install)
+
+## DolphinScheduler Cluster One-click Deployment 
+
+* Logging in and accessing the built-in open source app store, search the keyword `dolphinscheduler` to find the DolphinScheduler App.
+
+![](../../../../img/rainbond/appstore-dolphinscheduler.png)
+
+* Click `install` on the right side of DolphinScheduler to go to the installation page. Fill in the corresponding information and click `OK` to start the installation. You will get automatically redirected to the application view.
+
+| Select item  | Description                          |
+| ------------ | ------------------------------------ |
+| Team name    | user workspace，Isolate by namespace |
+| Cluster name | select kubernetes cluster            |
+| Select app   | select application                   |
+| app version  | select DolphinScheduler version      |
+
+![](../../../../img/rainbond/install-dolphinscheduler.png)
+
+* Wait a few minutes, the installation completes and `DolphinScheduler` will be running.
+
+![](../../../../img/rainbond/topology-dolphinscheduler.png)
+
+* Access DolphinScheduler-API components and the default user credentials are `admin` / `dolphinscheduler123`.
+
+![](../../../../img/rainbond/homepage-dolphinscheduler.png)
+
+## API Master Worker Node Telescopic
+
+DolphinScheduler API、Master、Worker all support scaling multiple instances, ensuring the high availability of the entire service.
+
+Take `worker` as an example: enter the `component -> Telescopic` page, and set the number of instances.
+
+![](../../../../img/rainbond/dolpscheduler-worker.png)
+
+To verify `worker` node, enter `DolphinScheduler UI -> Monitoring -> Worker` page to view detailed node information.
+
+![](../../../../img/rainbond/monitor-dolphinscheduler.png)
+## Configuration file
+
+API and Worker Services share the configuration file `/opt/dolphinscheduler/conf/common.properties`. To modify the configurations, you only need to modify that of the API service.
+
+## How to support Python 3？
+
+Worker service is installed with default `Python3`，you can add environment variables `PYTHON_HOME=/usr/bin/python3`
+
+## How to support Hadoop, Spark, DataX ？
+
+Take `DataX` as an example:
+
+1. Install the plugin。Rainbond Team View -> Plugin -> Install plugin from the App Store -> search `initialization plugin` Install.
+2. Open plugin.enter Worker component -> plugin -> open `initialization plugin` and modify the configuration.
+   * FILE_URL：http://datax-opensource.oss-cn-hangzhou.aliyuncs.com/datax.tar.gz
+   * FILE_PATH：/opt/soft
+   * LOCK_PATH：/opt/soft
+3. Update component, the plug-in `Datax` will be downloaded automatically and decompress to `/opt/soft`

+# 基于 Rainbond 部署 DolphinScheduler 高可用集群
+
+本文描述通过 [Rainbond](https://www.rainbond.com/) 云原生应用管理平台 一键部署高可用的 DolphinScheduler 集群，这种方式适合给不太了解 Kubernetes、容器化等复杂技术的用户使用，降低了在 Kubernetes 中部署 DolphinScheduler 的门槛。
+
+## 前提条件
+
+* 可用的 Rainbond 云原生应用管理平台，请参阅文档 [Rainbond 快速安装](https://www.rainbond.com/docs/quick-start/quick-install)
+
+## DolphinScheduler 集群一键部署
+
+* 对接并访问内置的开源应用商店，搜索关键词 `dolphinscheduler` 即可找到 DolphinScheduler 应用。
+
+![](../../../../img/rainbond/appstore-dolphinscheduler.png)
+
+* 点击 DolphinScheduler 右侧的 `安装` 进入安装页面，填写对应的信息，点击确定即可开始安装，自动跳转至应用视图。
+
+| 选择项   | 说明                                                         |
+| -------- | ------------------------------------------------------------ |
+| 团队名称 | 用户自建的工作空间，以命名空间隔离                           |
+| 集群名称 | 选择 DolphinScheduler 被部署到哪一个 K8s 集群                |
+| 选择应用 | 选择 DolphinScheduler 被部署到哪一个应用，应用中包含有若干有关联的组件 |
+| 应用版本 | 选择 DolphinScheduler 的版本，目前可选版本为 3.0.0-beta2     |
+
+![](../../../../img/rainbond/install-dolphinscheduler.png)
+
+* 等待几分钟后，DolphinScheduler 集群就会安装完成，并运行起来。
+
+![](../../../../img/rainbond/topology-dolphinscheduler.png)
+
+* 点击访问，将访问 DolphinScheduler-API 组件，默认的用户密码是`admin` / `dolphinscheduler123`
+
+![](../../../../img/rainbond/homepage-dolphinscheduler.png)
+
+## API Master Worker 节点伸缩
+
+DolphinScheduler API、Master、Worker 都支持伸缩多个实例，多个实例可以保证整个集群的高可用性。
+
+以 Worker 为例，进入组件内 -> 伸缩，设置实例数量。
+
+![](../../../../img/rainbond/dolpscheduler-worker.png)
+
+验证 Worker 节点，进入 DolphinScheduler UI -> 监控中心 -> Worker 查看节点信息。
+
+![](../../../../img/rainbond/monitor-dolphinscheduler.png)
+
+## 配置文件
+
+API 和 Worker 服务共用 `/opt/dolphinscheduler/conf/common.properties` ，修改配置时只需修改 API 服务的配置文件。
+
+## 如何支持 Python 3？
+
+Worker 服务默认安装了 Python3，使用时可以添加环境变量  `PYTHON_HOME=/usr/bin/python3`
+
+## 如何支持 Hadoop, Spark, DataX 等？
+
+以 Datax 为例：
+
+1. 安装插件。Rainbond 团队视图 -> 插件 -> 从应用商店安装插件 -> 搜索 `通用数据初始化插件` 并安装。
+2. 开通插件。进入 Worker 组件内 -> 插件 -> 开通  `通用数据初始化插件` ，并修改配置
+   * FILE_URL：http://datax-opensource.oss-cn-hangzhou.aliyuncs.com/datax.tar.gz
+   * FILE_PATH：/opt/soft
+   * LOCK_PATH：/opt/soft
+3. 更新组件，初始化插件会自动下载 `Datax` 并解压到 `/opt/soft`目录下。
