在MacOS上安装minikube

Posted 2021-04-30 云原生技术课堂

1. 检查环境

检查我们的macOS是不是支持虚拟化

sysctl -a | grep -E --color 'machdep.cpu.features|VMX'
machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3 PCLMULQDQ DTES64 MON DSCPL VMX EST TM2 SSSE3 FMA CX16 TPR PDCM SSE4.1 SSE4.2 x2APIC MOVBE POPCNT AES PCID XSAVE OSXSAVE SEGLIM64 TSCTMR AVX1.0 RDRAND F16C

如果看到结果中有VMX，VT-x功能就是启用的

2. 安装minikube

2.1. 安装brew

• 官方的方法安装

  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
  

• 修改源为aliyun的源 bash

  # 替换brew.git:
  cd "$(brew --repo)"
  git remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git
  # 替换homebrew-core.git:
  cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
  git remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git
  # 应用生效
  brew update
  # 替换homebrew-bottles:
  echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.bash_profile
  source ~/.bash_profile
  

  zsh

  # 替换brew.git:
  cd "$(brew --repo)"
  git remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git
  # 替换homebrew-core.git:
  cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
  git remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git
  # 应用生效
  brew update
  # 替换homebrew-bottles:
  echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.zshrc
  source ~/.zshrc
  

  2.2. 安装kubectl

  brew install kubectl
  

  或者

  brew install kubernetes-cli
  

  2.3. 安装minikube

  brew install minikube
  

  3. 启动minkube

  minikube start --image-repository='registry.cn-hangzhou.aliyuncs.com/google_containers'
  

  4. 部署应用

• 创建deployment

  kubectl create deployment nginx --image=nginx
  

• 暴露端口

  kubectl expose deployment nginx --type=LoadBalancer --port=80
  service/nginx exposed
  

• 查看服务

  kubectl get svc
  NAME         TYPE           CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
  kubernetes   ClusterIP      10.96.0.1      <none>        443/TCP        12m
  nginx        LoadBalancer   10.103.91.33   <pending>     80:31382/TCP   6s
  

• 访问我们的服务

  minikube service nginx
  |-----------|-------|-------------|---------------------------|
  | NAMESPACE | NAME | TARGET PORT | URL |
  |-----------|-------|-------------|---------------------------|
  | default   | nginx |             | http://192.168.64.2:31382 |
  |-----------|-------|-------------|---------------------------|
