我想在Rackspace中設置Kubernetes集羣，並且我知道要獲得持久卷支持，我需要使用Cinder （由Rackspace支持Openstack）。Kubernetes - 無法啓動與雲供應商OpenStack的kubelet（錯誤從雲提供商獲取當前節點名稱）
繼Cloud Provider Integrations setup指導，我已經安裝/etc/kubernetes/cloud-config如下
[Global]
username=cinder
password=********
auth-url=https://identity.api.rackspacecloud.com/v2.0
tenant-name=1234567
region=LON
我已在/etc/systemd/system/kubelet.service.d/10-kubeadm.conf
--cloud-provider=openstack --cloud-config=/etc/kubernetes/cloud-config
以下的kubelet啓動命令而我則運行kubeadm init --config=kubeadm.conf哪裏kubeadm.conf是：
kind: MasterConfiguration
apiVersion: kubeadm.k8s.io/v1alpha1
cloudProvider: openstack
pod-network-cidr: 10.244.0.0/16
等待Kubelet啓動失敗。我追查到kubelet錯誤如下：

如何進一步調試？我不太瞭解IP地址169.254.169.254在這個請求中的工作原理。
現在我不知道我是否有Kubernetes問題或Rackspace問題。
