安装Minikube

参考https://yq.aliyun.com/articles/221687 在Windows10上安装minikube

  1. 开启Hyper-V

    在 控制面板 - 程序和功能 - 启用或关闭Windows功能 中勾上 Hyper-V，重启设备

  2. 下载kubectl和minikube

    参考install-kubectl-on-windows下载kubectl

    当前的Relsease版是1.9.2，link。更改文件名为minikube.exe

    将上面两个文件放在同一个文件夹内，设置全局Path

  3. Hyper-V创建虚拟交换机

    首先应该打开Hyper-V管理器创建一个外部虚拟交换机。

记住这里设置的交换机名称，后面创建minikube时需要使用。例如我图中的就是MiniKubeSwitch.

  1. 安装minikube

    1
    minikube.exe start --image-mirror-country cn --iso-url=https://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/iso/minikube-v1.8.0.iso --registry-mirror=https://o61gnsy8.mirror.aliyuncs.com --vm-driver="hyperv" --hyperv-virtual-switch="MiniKubeSwitch" --memory=4096

测试Minikube

通过一个Kubernetes官方示例，启动Nginx来演示minikube的使用

下载Yaml配置

先下载几个yaml文件，可以直接从官方下载。也可以从我的网盘下载。

λ kubectl.exe apply -f deployment.yaml
deployment.apps/nginx-deployment created

deployment.yaml文件内容如下，部署脚本主要关注点就是Nginx的版本，后期会对1.14.2这个版本进行升级。

查看nginx-deployment的详情，可以看到StrategyType为RollingUpdate，属于升级操作，而且镜像版本号变为了1.16.1。
