Kubernetes pod没有将卷绑定到容器

我已经定义了以下ReplicationController JSON：

{
  "id": "PHPController",
  "kind": "ReplicationController",
  "apiVersion": "v1beta1",
  "desiredState": {
    "replicas": 2,
    "replicaSelector": {"name": "php"},
    "podTemplate": {
      "desiredState": {
         "manifest": {
           "version": "v1beta1",
           "id": "PHPController",
           "volumes": [{ "name": "wordpress", "path": "/mnt/nfs/wordpress_a", "hostDir": "/mnt/nfs/wordpress_a"}],
           "containers": [{
             "name": "php",
             "image": "internaluser/php53",
             "ports": [{"containerPort": 80, "hostPort": 9021}],
             "volumeMounts": [{"name": "wordpress", "mountPath": "/mnt/nfs/wordpress_a"}]
           }]
         }
       },
       "labels": {"name": "php"}
      }},
  "labels": {"name": "php"} 

}

使用“docker run -t -i -p 0.0.0.0:9021:80 -v / mnt / nfs / wordpress_a：/ mnt / nfs / wordpress_a：rw internaluser / php53”运行时，容器正确启动 .

/ mnt / nfs / wordpress_a是一个NFS共享，安装在所有的minions上 . 每个minion都有完整的RW访问权限，我已经确认共享存在 .

使用Replication Controller创建pod容器后，我可以看到该卷从未实际绑定和/或未正确装入：

"Volumes": {
        "/mnt/nfs/wordpress_a": "/var/lib/docker/vfs/dir/8b5dc8477958f5c1b894e68ab9412b41e81a34ef16dac81f0f9d4884352a90b7"
    },
    "VolumesRW": {
        "/mnt/nfs/wordpress_a": true
    }

    "HostConfig": {
        "Binds": null,
        "ContainerIDFile": "",
        "LxcConf": null,
        "Privileged": false,
        "PortBindings": {
            "80/tcp": [
                {
                    "HostIp": "",
                    "HostPort": "9021"
                }
            ]
        },

我觉得奇怪的是容器认为/ mnt / nfs / wordpress_a映射到“/ var / lib / docker / vfs / dir / 8b5dc8477958f5c1b894e68ab9412b41e81a34ef16dac81f0f9d4884352a90b7” .

从kubelet日志：

期望[10.101.4.15]：[{Namespace：etcd名称：c823da9e-4437-11e4-a3b1-0050568421eb Manifest：{Version：v1beta1 ID：c823da9e-4437-11e4-a3b1-0050568421eb UUID：c823da9e-4437-11e4-a3b1- 0050568421eb卷：[{Name：wordpress来源：}]容器：[{Name：php Image：internaluser / php53命令：[] WorkingDir：Ports：[{Name：HostPort：9021 ContainerPort：80 Protocol：TCP HostIP：}] Env ：[{Name：SERVICE_HOST Value：10.1.1.1}]内存：0 CPU：0 VolumeMounts：[{Name：wordpress ReadOnly：false MountPath：/ mnt / nfs / wordpress_a}] LivenessProbe：Lifecycle：Privileged：false}] RestartPolicy： {Always：0xa99a20 OnFailure：Never：}}}]

有没有人有这种经历？我一直在疯狂排除故障 . 谢谢！
