Is this a BUG REPORT or FEATURE REQUEST?:

Uncomment only one, leave it on its own line:

/kind bug

/kind feature

What happened:
according to the Reconfigure a Node's Kubelet in a Live Cluster page, we can use /configz to fetch the whole config of kubelet. The question is, this API just reports 404 in 1.10 release which works fine in 1.8 in my setup.

What you expected to happen:
Is it not supported any more in the 1.10 release? Or just something wrong with my setup?

How to reproduce it (as minimally and precisely as possible):
try this command in this page:
curl -sSL http://localhost:8001/api/v1/proxy/nodes/${NODE_NAME}/configz
and it returns as follow:
{
"kind": "Status",
"apiVersion": "v1",
"metadata": {

},
"status": "Failure",
"message": "the server could not find the requested resource",
"reason": "NotFound",
"details": {

},
"code": 404
}

Anything else we need to know?:

Can you verify if the feature gate is enabled?

@phsiao yes, still not working with the DynamicKubeletConfig on.
I created a config file with the followings:

kind: KubeletConfiguration
apiVersion: kubelet.config.k8s.io/v1beta1
address: 0.0.0.0
staticPodPath: /etc/kubernetes/manifests
clusterDNS: [10.254.0.10]
clusterDomain: cluster.local
kubeReserved:
  cpu: 500m
  memory: 500Mi
systemReserved:
  cpu: 500m
  memory: 500Mi
failSwapOn: false
featureGates:
  DevicePlugins: false
  DynamicKubeletConfig: true

and dynamic-config-dir in the command line
the kubelet works fine and I'm sure the DevicePlugin doesn't work since the param has been set to false. But /configz still not works.

/api/v1/proxy/nodes/${NODE_NAME}/configz/ is deprecated in 1.10.
Please use /api/v1/nodes/<my-node>/proxy/configz instead.
