minikube安装与运行（阿里云环境运行）-Toy模板网

这篇具有很好参考价值的文章主要介绍了minikube安装与运行（阿里云环境运行）。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

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。 minikube 阿里云,阿里云,运维,云计算

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

apt-get update

apt install docker.io

root@iZmj7hlj4my4j4dgaiq763Z:~# apt install docker.io

Y就行了。安装完查看docker版本

root@iZmj7hlj4my4j4dgaiq763Z:~# docker -v
Docker version 20.10.21, build 20.10.21-0ubuntu1~18.04.2

3.安装minikube

Welcome! | minikube

可以参考官网。选择下Linux、x86-64、stable、binary download

minikube 阿里云,阿里云,运维,云计算

 curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64

下载安装包

root@iZmj7hlj4my4j4dgaiq763Z:~# curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

安装

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
✨  Automatically selected the docker driver. Other choices: none, ssh
🛑  The "docker" driver should not be used with root privileges. If you wish to continue as root, use --force.

⛔  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'

3.安装kubectl

在 Linux 系统中安装并设置 kubectl | Kubernetes

curl -LO https://dl.k8s.io/release/v1.26.0/bin/linux/amd64/kubectl

sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

查看版本

kubectl version

root@iZmj7hlj4my4j4dgaiq763Z:~# kubectl version
WARNING: This version information is deprecated and will be replaced with the output from kubectl version --short.  Use --output=yaml|json to get the full version.

4.通过kubectl查看刚启动minikube

kubectl get pod -A
