Kubernetes：主节点列在'kubectl get po'列表中？

Question

今天从 github 中提取了最新的 kubernetes 代码。

步骤：在一个名为 dpcdd3 的 Ubuntu 服务器上运行 docs/getting-started-guides/docker-multinode/master.sh。或者，这里是网址：

https://github.com/kubernetes/kubernetes/blob/master/docs/getting-started-guides/docker-multinode/master.sh

# kubectl get no
NAME      LABELS                          STATUS    AGE
dpcdd3    kubernetes.io/hostname=dpcdd3   Ready     1h

（注意：worker.sh 尚未在第二台服务器上调用）。

在较旧的代码（大约一个月前随机选择）上，相同的命令，在相同的设置中："kubectl get no"不会返回任何内容。

以下是一些当前的运行时详细信息：

# kubectl version
Client Version: version.Info{Major:"1", Minor:"2+", GitVersion:"v1.2.0-alpha.6.239+a5d2c1b0fb23a1", GitCommit:"a5d2c1b0fb23a145c47935f041a036d8546cd01f", GitTreeState:"clean"}
Server Version: version.Info{Major:"1", Minor:"1", GitVersion:"v1.1.3", GitCommit:"6a81b50c7e97bbe0ade075de55ab4fa34f049dc2", GitTreeState:"clean"}

有趣的是，豆荚显示状态为："待处理"：

# kubectl get po
NAME                READY     STATUS    RESTARTS   AGE
k8s-master-dpcdd3   0/3       Pending   0          1h
