kubelet syscontainer can't get the /dev/disk of host

[FengyunPan2]

My openstack env have not metadata service, so I can't get vm metadata by metadata service.
When I start kubelet, I get he following error:
1 openstack_instances.go:39] openstack.Instances() called
3 09:31:34.882593 1 openstack_instances.go:46] Claiming to support Instances
3 09:31:34.890697 1 metadata.go:151] Attempting to fetch metadata from http://169.254.169.254/openstack/2012-08-10/meta_data.json
r setting the external host value: failed to get NodeName from "openstack" cloud provider: unexpected status code when reading metadata from http://169.254.169.254/openstack/2012-08-10/meta_

the reason is:
kubernetes openstack cloud provider can't get the vm metadata from '/dev/disk', then try to use metadata service.

fix:
Bind /dev/disk for kubernete service.

We mount /dev for kubelet.

For kube-apiserver and kube-controller-manager, the problem appears in devstack too?

Just for kubelet.
