+# 使用CephFS作为分布式存储
+
+- 在使用CephFS之前，你需要知道Ceph集群的以下信息
+  - *monitors*: Ceph集群的monitor节点地址
+  - *path*: 你有权限的CephFS上的目录，默认为根目录
+  - *secret*: cephfs的secret，通常会作为Kubernetes的secret保存在集群，
+  也可以参考[cephfs-secret.yaml](./cephfs-secret.yaml)自行提交
+- 使用方法
+  1. 查看是否已存在ceph-secret,若看到已下输入说明已创建过ceph-secret，可跳过步骤2
+  ```bash
+  >kubectl get secret
+  NAME            TYPE          DATA          AGE
+  ceph-secret     Opaque        1             19m
+  ```
+  1. 添加ceph-secret,从管理获取ceph集群的secret,并替换下面命令中的`<ceph-secret>`变量
+  ```bash
+  echo -n "<ceph-secret>" | base64
+  ```
+  将上面命令输出的base64编码替换`ceph-secret.yaml`中的<key>
+  ```yml
+  apiVersion: v1
+  kind: Secret
+  metadata:
+      name: ceph-secret
+  data:
+      key: <key>
+  ```
+  ```bash
+  kubectl create -f ceph-secret.yaml
+  ```
+  1. 参考[pod.yaml](./pod.yaml)提交pod
+  ```bash
+  kubectl create -f pod.yaml
+  ```
