<body>命令并无法连接服务器：EOF
在过去的两天里，我一直在尝试各种论坛和帮助，但不确定丢失了什么。
步骤：
我启动了一个t2.micro Ubuntu EC2实例。
以下是所安装软件的详细信息：
kubectl我在定义AWS Access密钥/私有密钥和S3存储桶之后创建集群：
$ kops version
Version 1.10.0 (git-8b52ea6d1)
$ aws --version
aws-cli/1.16.43 Python/3.6.6 Linux/4.15.0-1021-aws botocore/1.12.33
$ kubectl version
Client Version: version.Info{Major:"1", Minor:"12", GitVersion:"v1.12.2",
GitCommit:"17c77c7898218073f14c8d573582e8d2313dc740", GitTreeState:"clean",
BuildDate:"2018-10-24T06:54:59Z", GoVersion:"go1.10.4", Compiler:"gc",
Platform:"linux/amd64"}
Unable to connect to the server: EOF
我得到以下输出：
$ kops create cluster clusters.k8s.local --zones us-east-1a --ssh-public-key kubernetes.pub --yes
我看到在我的S3存储桶下创建了clusters.k8s.local。
$ kops create cluster clusters.k8s.local --zones us-east-1a --ssh-public-key kubernetes.pub --yes

kops has set your kubectl context to clusters.k8s.local
Cluster is starting. It should be ready in a few minutes.
Suggestions:
* validate cluster: kops validate cluster
* list nodes: kubectl get nodes --show-labels
* ssh to the master: ssh -i ~/.ssh/id_rsa admin@api.clusters.k8s.local
* the admin user is specific to Debian. If not using Debian please use the appropriate user based on your OS.
* read about installing addons at: https://github.com/kubernetes/kops/blob/master/docs/addons.md.
验证kops集群：
$ kubectl cluster-info
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

当我运行nslookup命令时：
$ kops validate cluster
