本地搭建kubernetes环境

此篇文章主要是介绍如何通过minikube快速部署一个k8s环境用作学习和实验。我演示的机器是macOS，k8s版本是1.15.x 最新版本。无需翻墙哦。

条件准备

• 安装虚拟化软件virtualbox驱动

brew cask install virtualbox 

• 安装kubectl 客户端

brew install kubernetes-cli

• 下载阿里云minikube

curl -Lo minikube http://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/releases/v1.2.0/minikube-darwin-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

开始搭建

• 启动minikube安装k8s 1.15.0 版本

minikube start --registry-mirror=https://registry.docker-cn.com --kubernetes-version v1.15.0

• 成果验证

# 查看节点
$ kubectl get node
NAME STATUS ROLES AGE VERSION
minikube Ready master 10m v1.15.0

# 查看kube-system ns 下的pod状态
$ kubectl get pod -n kube-system
