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都有完全的RW访问权限，我已经确认该共享存在。
使用Replication Controller创建pod容器后，我可以看到该卷实际上从未被绑定和/或未正确安装：
"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”。
来自kubelet日志：

有没有人有这方面的经验？我一直在疯狂排除故障。谢谢！
