# 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> | ||
