kubectl是Kubernetes集群的命令行工具，通过kubectl能够对集群本身进行管理，并能够在集群上进行容器化应用的安装部署。

``` bash
cd /opt/k8s/work
wget https://dl.k8s.io/v1.14.2/kubernetes-client-linux-amd64.tar.gz
tar -xzvf kubernetes-client-linux-amd64.tar.gz
```

从dl.k8s.io下载不了的，还有另一个方法：

curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl

查看下载了哪个版本：

[root@zhangjun-k8s02 bin]# ./kubectl version
