+## 分布式部署 open-falcon 到 k8s 集群
+
+### 构建
+
+克隆源码：
+
+```shell
+git clone https://github.com/open-falcon/falcon-plus.git && cd falcon-plus 
+```
+
+编译源码并构建 Docker 镜像
+
+```shell
+./docker/k8s-cluster/build.sh
+```
+
+### 部署
+
+注意点：
+
+1. graph 为有状态组件，部署方式为每个节点一个 Deployment，同时 replica 设置为 1
+2. 所有配置文件使用挂载目录的方式持久化，可以改为 ConfigMap 管理配置
+3. 镜像可以使用构建脚本自己构建后推送到自己的私仓使用（推荐），或者直接使用我构建好的，仓库地址在 docker/k8s-cluster/build.sh 查看或修改
