Kubernetes 环境搭建 - MacOS
准备工作
1、Mac 环境需求
Minikube 要求在 BIOS 中启用 VT-x / AMD-v 虚拟化， 要检查这是否在OSX / macOS上运行，请执行以下操作：
sysctl -a | grep machdep.cpu.features | grep VMX
如果有输出，那你很棒棒！
2、【推荐】使用清华的 brew 镜像源
cd "$(brew --repo)"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
brew update
相关软件安装
- kubectl
- docker (for Mac)
- minikube
- virtualbox
brew update && brew install kubectl && brew cask install docker minikube virtualbox
校验软件版本信息
docker --version # Docker version 18.03.1-ce, build 9ee9f40
docker-compose --version # docker-compose version 1.21.1, build 5a3f1a3
docker-machine --version # docker-machine version 0.14.0, build 89b8332
minikube version # minikube version: v0.26.1
kubectl version --client # Client Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.1", GitCommit:"d4ab47518836c750f9949b9e0d387f20fb92260b", GitTreeState:"clean", BuildDate:"2018-04-13T22:28:25Z", GoVersion:"go1.9.5", Compiler:"gc", Platform:"darwin/amd64"}
开始
1、启动 kubernetes 集群
minikube start --bootstrapper=localkube
一会后，会有如下输出

恭喜！Minikube 为你启动了一个虚拟机，并在该虚拟机中运行了 Kubernetes 集群。
2、查看集群节点信息
➜ ~ kubectl get nodes
NAME STATUS ROLES AGE VERSION
minikube Ready 15m v1.10.0
常见问题及解决办法
1、kubectl 安装失败
➜ brew install kubectl
