Windows安装Minikube体验Kubernetes(k8s)集群

Kubernetes(k8s) 用于协调高度可用的计算机集群，Minikube用于学习和测试使用，可以在一台节点上很方便的部署 Kubernetes(k8s) 集群环境。

一、环境

Win10：直接在win10使用 Minikube，没有使用虚拟机。Windows必须支持虚拟化，可以执行“systeminfo”命令来确认。

二、安装

下载 Minikube，下载地址。Minikube 是绿色软件，下载后放到 C:\Windows\目录下即可。
下载 kubectl，下载地址。kubectl 是管理 Kubernetes 集群的命令行工具，也是绿色软件，下载后放到 C:\Windows\目录下即可。
安装 Docker ，官网下载安装包，一路下一步安装即可。安装之后，需要打开一次来确认安装是否成功。

三、运行

minikube start --disk-size="10g"  --image-mirror-country="cn"  --image-repository="registry.cn-hangzhou.aliyuncs.com/google_containers"

如果报下面的错误，请将 172.217.160.112 storage.googleapis.com 加入 C:\Windows\System32\drivers\etc\hosts 文件的末尾一行。

出现下面的 Done 提示，表示安装成功。

四、最后验证一下

kubectl cluster-info

出现下面的错误表示安装成功：

Kubernetes control plane is running at https://127.0.0.1:59750
CoreDNS is running at https://127.0.0.1:59750/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
