Question

我在Mac上是新手。我按照instructions安装了kubectl-cli 但是，通过命令kubectl version检查版本时，出现以下错误：

Client Version: version.Info{Major:"1", Minor:"13", GitVersion:"v1.13.1", GitCommit:"eec55b9ba98609a46fee712359c7b5b365bdd920", GitTreeState:"clean", BuildDate:"2018-12-13T19:44:19Z", GoVersion:"go1.11.2", Compiler:"gc", Platform:"darwin/amd64"}
The connection to the server localhost:8080 was refused - did you specify the right host or port?

我确实遵循了一些questions，发现kubernetes文件夹中没有名为/etc/的目录。

其原因是kubectl version会同时打印客户端版本和服务器版本（kubernetes版本）。当您只安装kubectl时，它只是kubernets客户端。如果您安装了kubernetes集群，它将同时打印kubectl版本和kubernetes版本。

如果只想打印客户端版本，请使用以下命令：

kubectl version --client=true

该错误表示kubectl tried to contact the kubernetes server to get its version but couldn't connect. Are you specifying the right host or port to connect to the kubernetes server.

错误的原因是您尚未在Mac上安装kubernetes集群。您刚刚安装了kubectl，它只是访问kubernetes集群的客户端。安装kubernetes集群后，kubectl version的输出将类似于：

[root@ip-10-0-1-138 centos]# kubectl version
Client Version: version.Info{Major:"1", Minor:"13", GitVersion:"v1.13.1", GitCommit:"eec55b9ba98609a46fee712359c7b5b365bdd920", GitTreeState:"clean", BuildDate:"2018-12-13T10:39:04Z", GoVersion:"go1.11.2", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.3", GitCommit:"2bba0127d85d5a46ab4b778548be28623b32d0b0", GitTreeState:"clean", BuildDate:"2018-05-21T09:05:37Z", GoVersion:"go1.9.3", Compiler:"gc", Platform:"linux/amd64"}

如果要在Mac上安装完整的kubernetes集群，请尝试minikube在本地安装集群
