Mac + Docker + K8S 本地搭建K8S集群

Mac + Docker + K8S 本地搭建K8S集群
### 安装
* `Docker for Desktop` **v4.10.1**
* `Kubernetes` **v1.24.0**
> 建议采用阿里云的`k8s-for-docker-desktop`， 同时可以解决经常遇到的 `Docker for Desktop` 中的 K8S 一直卡在 `starting` 状态。

1. 安装 Docker for Desktop

[Docker for Desktop 下载链接](https://www.docker.com/products/docker-desktop/)

查看 `Kubernetes` 版本

2. 克隆阿里云的 `k8s-for-docker-desktop` 镜像

```
git clone https://github.com/AliyunContainerService/k8s-for-docker-desktop.git
cd k8s-for-docker-desktop
 
// 执行脚本安装K8S相关镜像（确认k8s-for-docker-desktop文件夹下的images中的k8s和本地安装的docker中需要的k8s版本保持一致）
./load_images.sh
```
等待安装成功

3. 设置`docker`代理和`k8s`的设置，并重启 `Docker for Desktop`

`Docker` 开启 `Kubernetes`

开启成功后状态如下：

### 配置 K8S

```
// 切换k8s的上下文状态到docker-desktop
kubectl config use-context docker-desktop
// 验证集群状态
kubectl cluster-info
kubectl get nodes
```

### 配置K8S 的控制台

```
kubectl create -f kubernetes-dashboard.yaml
 
// 检查kubernetes-dashboard的应用状态
kubectl get pod -n kubernetes-dashboard
 
// 开启API Server应用代理
kubectl proxy
```
![](https://www.qsjob.fun/zb_users/upload/2022/07/202207281657161708782.jpg)
![](https://www.qsjob.fun/zb_users/upload/2022/07/202207281657267038216.jpg)

通过 `Url` 可以访问 `Kubernetes dashboard` 链接如下：
http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/#/login
>（如果访问页面报错：x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "kubernetes")

>可以能是第一次安装失败导致，把k8s相关的都删了重新来。

### 配置控制令牌

```
// 生成默认空间配置文件
kubectl apply -f kube-system-default.yaml
// 生成配置令牌 Token
TOKEN=$(kubectl -n kube-system describe secret default| awk '$1=="token:"{print $2}')
kubectl config set-credentials docker-desktop --token="${TOKEN}"
echo $TOKEN
```
![](https://www.qsjob.fun/zb_users/upload/2022/07/202207281657363199979.jpg)

生成的`token`输入到下列令牌
