kubernetes节点未注册

我正在尝试使用rkt通过CoreOS alpha（1284.2.0）在Container Linux上使用kubernetes 1.5.2 .

我有两个coreos服务器，一个（控制器工作者）主机名 coreos-2.tux-in.com ，第二个将是主机名 coreos-3.tux-in.com 的工作 .

现在我在 coreos-2.tux-in.com 安装控制器工作人员 .

一般来说，我按照https://coreos.com/kubernetes/docs/latest/中的说明进行了一些修改 .

而不是使用已弃用的 --api-server 参数我使用kubeconfig .

我遇到的问题是kube-proxy pod失败并出现以下错误消息：

Jan 14 23:27:34 coreos-2.tux-in.com rkt[11555]: [  220.477192] kube-proxy[5]: E0114 23:27:34.900184       5 server.go:421] Can't get Node "coreos-2.tux-in.com", assuming iptables proxy, err: nodes "coreos-2.tux-in.com" not found

kubeconfig位于 /etc/kubernetes/controller-kubeconfig.yaml ，具有以下内容：

apiVersion: v1
kind: Config
clusters:
- cluster:
    server: http://127.0.0.1:8080

这是kube-apisever的清单：

这是kube-proxy的清单：

apiVersion: v1

    hostPath:
      path: "/etc/kubernetes/ssl"
  - hostPath:
      path: /var/run/dbus
    name: dbus

/etc/kubernetes/manifests 还包括运河，kube-controller-manager，kube-scheduler和kubernetes-dashboard .

我的桌面上有 kubectl ，在 ~/.kube/config 配置了以下内容：

apiVersion: v1
clusters:
- cluster:
    certificate-authority: /Users/ufk/Projects/tuxin-coreos/kubernetes/certs/ca.pem
    server: https://coreos-2.tux-in.com
  name: tuxin-coreos-cluster
contexts:
- context:
    cluster: tuxin-coreos-cluster
    user: default-admin
  name: tuxin-coreos-context
current-context: tuxin-coreos-context
kind: Config
preferences: {}
users:
- name: default-admin
  user:
    username: kubelet
    client-certificate: /Users/ufk/Projects/tuxin-coreos/kubernetes/certs/client.pem
    client-key: /Users/ufk/Projects/tuxin-coreos/kubernetes/certs/client-key.pem

当我执行 kubectl get nodes 时，我得到 No resources found.

所以不知何故当前节点没有注册...

这是我的 kubelet.service 文件：

我有 --hostname-override=coreos-2.tux-in.com 设置，所以我猜它's supposed to register the node but doesn' t .

我从这里做什么
