说下为啥选择云环境，最开始在本地电脑上安装的minikube，但是由于国内的网络访问不了谷歌的镜像仓库，安装ingress-nginx或者其他插件时着实的恶心。要不翻墙，要不自己搭建个镜像仓库。最终决定用阿里云境外的节点，按小时收费的那种，一个小时大概也就3毛钱。随时释放，不会因为这些环境和网络的问题分神。
1.准备环境
阿里云登录 - 欢迎登录阿里云，安全稳定的云计算服务平台
没有账号注册一个，或者使用支付宝登陆。这里就不做赘述了。
选择“云服务ECS”
创建实例
一定选择国外的节点 ，我选择是韩国首尔的节点，这个便宜。CPU2核，内存2G。操作系统选的是ubuntu18.04（看自己喜好linux哪个都行），磁盘不用修改40G和20G一样钱。
下一步网络设置。需要自建一个交换机和安全组，就按推荐的建。分配公网IP选上，按流量收费。
下一步系统配置,配置自定义密码登陆的方式，给root用户设置一个秘密，设置个自己喜欢的。
确认订单。创建实例。账户需要有100块钱（按时间扣费用）。
控制台多了刚才创建的实例，我刚新建的外网ip是8.213.130.127（基本用几个小时我就释放了，不怕暴露），此时在你机器的本地就可以通过ssh对这台机器登陆了。
补充下安全组，默认创建的安全组会开放22、80端口，所以本机才可以使用ssh登陆。
本地登陆
ssh root@8.213.130.127
2.安装docker

root@iZmj7hlj4my4j4dgaiq763Z:~# docker -v
Docker version 20.10.21, build 20.10.21-0ubuntu1~18.04.23.安装minikube
Welcome! | minikube
可以参考官网。选择下Linux、x86-64、stable、binary download
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64

sudo install minikube-linux-amd64 /usr/local/bin/minikube启动
minikube start提示xxx，直接加一个--force。
root@iZmj7hlj4my4j4dgaiq763Z:~# minikube start
😄 minikube v1.30.1 on Ubuntu 18.04 (amd64)
✨ Automatically selected the docker driver. Other choices: ssh, none
🛑 The "docker" driver should not be used with root privileges. If you wish to continue as root, use --force.
💡 If you are running minikube within a VM, consider using --driver=none:
📘 https://minikube.sigs.k8s.io/docs/reference/drivers/none/
❌ Exiting due to DRV_AS_ROOT: The "docker" driver should not be used with root privileges.minikube start --force启动成功，还有一个提示是内存小于最小内存1900MB了。学习环境不用理这个错误。
root@iZmj7hlj4my4j4dgaiq763Z:~# minikube start --force
😄 minikube v1.30.1 on Ubuntu 18.04 (amd64)
❗ minikube skips various validations when --force is supplied; this may lead to unexpected behavior

⛔ Requested memory allocation (1889MB) is less than the recommended minimum 1900MB. Deployments may fail.
🧯 The requested memory allocation of 1889MiB does not leave room for system overhead (total system memory: 1889MiB). You may face stability issues.
💡 Suggestion: Start minikube with less memory allocated: 'minikube start --memory=1889mb'

在 Minikube 环境中使用 NGINX Ingress 控制器配置 Ingress | Kubernetes
这里就不截图了，安装上面地址一步一步执行，全部都可以成功。亲测。
6.释放ECS实例
不用的时候可以直接释放了。资源配置旁边的点点点。藏的有点深，搜索下“释放”。
