我按照示例在kubernetes中使用rbd，但不能成功。谁能帮我！！错误 ：

我使用 rbd-with-secret.json 的模板文件：

core@core-1-94 ~/kubernetes/examples/rbd $ cat rbd-with-secret.json
{
"apiVersion": "v1",
"id": "rbdpd2",
"kind": "Pod",
"metadata": {
    "name": "rbd2"
},
"spec": {
    "nodeSelector": {"kubernetes.io/hostname" :"10.12.1.97"},
    "containers": [
        {
            "name": "rbd-rw",
            "image": "kubernetes/pause",
            "volumeMounts": [
                {
                    "mountPath": "/mnt/rbd",
                    "name": "rbdpd"
                }
            ]
        }
    ],
    "volumes": [
        {
            "name": "rbdpd",
            "rbd": {
                "monitors": [
            "10.14.1.33:6789",
        "10.14.1.35:6789",
            "10.14.1.36:6789"
            ],
                "pool": "rbd",
                "image": "foo",
                "user": "admin",
                "secretRef": {"name": "ceph-secret"},
                "fsType": "ext4",
                "readOnly": true
            }
        }
    ]
}
}

秘诀：

apiVersion: v1
kind: Secret
metadata:
  name: ceph-secret
data:
  key: QVFBemV6bFdZTXdXQWhBQThxeG1IT2NKa0QrYnE0K3RZUmtsVncK

ceph 配置在 /etc/ceph/

core@core-1-94 ~/kubernetes/examples/rbd $ ls -alh /etc/ceph
total 20K
drwxr-xr-x  2 root root 4.0K Nov  6 18:38 .
drwxr-xr-x 26 root root 4.0K Nov  9 17:07 ..
-rw-------  1 root root   63 Nov  4 11:27 ceph.client.admin.keyring
-rw-r--r--  1 root root  264 Nov  6 18:38 ceph.conf
-rw-r--r--  1 root root  384 Nov  6 14:35 ceph.conf.orig
-rw-------  1 root root    0 Nov  4 11:27 tmpkqDKwf

键为：

    core@core-1-94 ~/kubernetes/examples/rbd $ sudo cat              
    /etc/ceph/ceph.client.admin.keyring
    [client.admin]
          键 = AQAzezlWYMwWAhAA8qxmHOcJkD+bq4+tYRklVw==

如果没有安装 rbd 命令并且在路径中，您将得到“没有匹配的卷插件”。

如示例所示，您需要确保 ceph 已安装在 Kubernetes 节点上。例如，在 Fedora 中： $ sudo yum -y install ceph-common

我将提出一个问题以澄清错误消息。
