+# Helm部署OpenEBS存储
+
+## 介绍
+
+**OpenEBS是一种开源云原生存储解决方案，托管于CNCF基金会**。OpenEBS 管理每个 Kubernetes 节点上可用的存储，并使用该存储为有状态工作负载提供[本地](https://openebs.io/docs#local-volumes)或[分布式（也称为复制）](https://openebs.io/docs#replicated-volumes)持久卷。
+
+## 安装 OpenEBS
+
+[官方主页](https://openebs.io/)
+
+[Github仓库](https://github.com/openebs/charts)
+
+[Helm安装文档](https://openebs.github.io/charts/)
+
+1. 添加仓库
+
+   ```bash
+   helm repo add openebs https://openebs.github.io/charts
+   helm repo update
+   ```
+
+2. 编辑 values.yaml 文件
+
+   ```bash
+   vi openebs-values.yaml
+   ```
+
+   内容如下
+
+   ```yaml
+   localprovisioner:
+     enableDeviceClass: false
+   ```
+
+3. 安装
+
+   [Github-Charts参数文档](https://github.com/openebs/charts/tree/d-master/charts/openebs)
+
+   ```bash
+   helm install openebs --namespace openebs openebs/openebs --create-namespace -f openebs-values.yaml
+   ```
+
+4. 检查 storageclass
+
+   ```bash
+   kubectl get sc
+   ```
+
+   > 存在 openebs-hostpath 则👌
+
+5. 运行容器使用 openebs-hostpath 测试
+
+   [openebs-hostpath官方文档](https://openebs.io/docs/user-guides/localpv-hostpath)
+
+   ```bash
+   kubectl apply -f https://gitee.com/offends/Kubernetes/raw/main/File/Yaml/openebs-pod.yaml
+   ```
+
+   > 容器启动后查看结果
+   >
+   > ```bash
+   > kubectl exec hello-local-hostpath-pod -- cat /mnt/store/greet.txt
+   > ```
+   >
+   > 卸载测试容器
+   >
+   > ```bash
+   > kubectl delete -f https://gitee.com/offends/Kubernetes/raw/main/File/Yaml/openebs-pod.yaml
+   > ```
+
+## 设置 openebs-hostpath 为默认存储类
+
+```bash
+kubectl patch storageclass openebs-hostpath  -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}' 
+```
+
+> 取消 openebs-hostpath 为默认存储类
+>
+> ```bash
+> kubectl patch storageclass openebs-hostpath -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'
+> ```
+
+## 卸载 OpenEBS
+
+```bash
+helm uninstall openebs -n openebs
+```
+
+# 问题记录
+
+MountVolume.NewMounter initialization failed for volume "pvc-某某" : path "/var/openebs/local/pvc-某某" does not exist
+
+> 在将创建本地 PV 主机路径的节点上设置目录, 该目录将被称为 `BasePath` 默认位置是 `/var/openebs/local`
+
+- Rke1 集群配置
+
+  修改 `cluster.yml` 文件,  后更新 rke 集群
+
+  ```yml
+  services:
+    kubelet:
+      extra_binds:
+        - /var/openebs/local:/var/openebs/local
+  ```
+
+  
+
