一、安裝ceph客戶端工具

### --- 安裝ceph客戶端
~~~     # 切換到ceph目錄下

[root@k8s-master01 ~]# cd /root/rook/cluster/examples/kubernetes/ceph

### --- 安裝ceph客戶端

[root@k8s-master01 ceph]# kubectl  create -f toolbox.yaml -n rook-ceph
deployment.apps/rook-ceph-tools created

### --- 待容器Running後，即可執行相關命令

[root@k8s-master01 ceph]# kubectl  get po -n rook-ceph -l app=rook-ceph-tools
NAME                               READY   STATUS    RESTARTS   AGE
rook-ceph-tools-58bbc55d4c-j6fgl   1/1     Running   0          10s

二、ceph客戶端使用示例

### --- 進入rook-ceph-tools容器內部

[root@k8s-master01 ceph]# kubectl -n rook-ceph exec -it deploy/rook-ceph-tools -- bash
