ubuntu server 22.04安装 minikube

环境准备

Vmware 虚拟机中安装 Ubuntu 22.04 server，完成系统的基本配置。

安装 MiniKube

安装脚本借鉴于:https://blog.csdn.net/LeoForBest/article/details/126524892，在此基础上做了修改。

#!/usr/bin/bash
# ~~~~~~~~~
# Ubuntu 22.04 Minikube install
# Update Author: yuluo
# Usage: bash install.sh (不要sudo,使用普通用户)

kubectl get pods -A

echo -e "\n 为 root 用户添加 kubectl 的执行权限，原因如下：因为 minikube 在普通用户下启动，root 用户下无 minikube 应用。所以使用时会 8080 refused"

sudo mkdir -p /root/.kube
sudo cp $HOME/.kube/config /root/.kube
sudo su

echo -e "\n 更多信息可参考: https://minikube.sigs.k8s.io/docs/start/"

安装最终效果如下：

部署 MiniKube Dashboard

1. minikube dashboard
2. kubectl get pods -A | grep dashboard
3. 配置远程访问

   kubectl proxy --address='0.0.0.0' --disable-filter=true
   

4. 浏览器访问：

      http://ip:8001/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/
