|NO.Z.00239|——————————|^^ 部署 ^^|——|KuberNetes&存储进阶.V05|——|Ceph.v04|ceph集群|ceph客户端工具|

一、安装ceph客户端工具

### --- 安装ceph客户端
~~~     # 切换到ceph目录下

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

### --- 安装ceph客户端

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

### --- 待容器Running后，即可执行相关命令

[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客户端使用示例

### --- 进入rook-ceph-tools容器内部

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

~~~     # 查看ceph集群状态

[root@rook-ceph-tools-58bbc55d4c-w4shn /]# ceph status
