# 从客户端电脑远程管理 Kubernetes
|
||
|
||
日常工作中，您可能需要在自己的笔记本电脑上执行 kubectl 命令以管理远程 Linux 服务器上的 Kubernetes 集群。
|
||
|
||
::: tip
|
||
从客户端电脑使用 kubectl 远程管理 Kubernetes，这个步骤并不是使用 Kuboard 的必要步骤。<span style="color: red; font-weight: 500;">可以忽略</span>

|
||
|
||
## 在客户端电脑安装 kubectl
|
||
|
||
Kubernetes 官网文档参照 [安装 kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/) 安装时，经常会失败，因为国内访问 google 的镜像仓库存在问题。
|
||
|
||
请参考下述内容，完成 kubectl 的安装
|
||
|
||
:::: tabs type:border-card
|
||
|
||
::: tab Linux lazy
|
||
|
||
**配置K8S的yum源**
|
||
|
||
```bash
|
||
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
|
||
[kubernetes]
|
||
name=Kubernetes
|
||
baseurl=http://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
|
||
enabled=1
|
||
gpgcheck=0
|
||
repo_gpgcheck=0
|
||
gpgkey=http://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
|
||
http://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
|
||
EOF
|
||
```
|
||
|
||
**安装kubectl**
|
||
|
||
```bash
|
||
yum install -y kubectl-1.15.1
|
||
```
|
||
|
||
**验证安装**
|
||
|
||
```bash
|
||
kubectl version
|
||
```

## 获取 kubectl config 文件
|
||
|
||
如果您参考 [安装 Kubernetes 单Master节点](install-k8s.html) 或 [安装 Kubernetes 高可用](install-kubernetes.html) 完成了 Kubernetes 安装，**请在 demo-master-a-1 节点上执行如下命令**
|
||
|
||
```sh
|
||
cat /etc/kubernetes/admin.conf
|
||
```
|
||
|
||
输出内容如下所示：
|

```yaml {5}

## 配置 kubectl 客户端
|
||
|
||
在客户端电脑完成如下配置，即可远程管理 Kubernetes 集群
|
||
|
||
:::: tabs type:border-card
|
||
|
||
::: tab Linux lazy
|
||
|
||
**执行命令**
|
||
|
||
```sh
|
||
vi ~/.kube/config
|
||
```
|
||
|
||
将前面获得的 `/etc/kubernetes/admin.conf` 文件的内容粘贴进该文件并保存
|
||
|
||
**配置 hosts**
|
||
|
||
```sh
|
||
echo "x.x.x.x apiserver.demo" >> /etc/hosts
|
||
```
|
||
|
||
> * 将 x.x.x.x 替换成 demo-master-a-1 的实际 IP 地址
|
||
> * 将 apiserver.demo 替换成前面获得 `/etc/kubernetes/admin.conf` 文件中 `clusters/cluster/server` 中 URL 里 host 对应的部分
|
||
|
||
**验证安装结果**
|
||
|
||
执行命令
|
||
|
||
```sh
|
||
kubectl get nodes
|
||
kubectl get pods -n kube-system
|
||
```
