Kubernetes:在“kubectl get po”列表中列出的主节点？

Question

最新的kubernetes代码今天从github调出。

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

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:还没有在第二台服务器上调用worker.sh )。

在一个较旧的代码(大约一个月前随机选择)上，相同的设置中相同的命令：“kubectl”不会返回任何内容。

下面是一些当前运行时的详细信息：

# 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，豆荚显示的状态是：“待定”：

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