Minikube¶

Minikube是一个可以快速搭建Kubernetes的工具

Minukube 文档 https://minikube.sigs.k8s.io/docs/start/

下载： https://github.com/kubernetes/minikube/releases

Pre-Requirements¶

Minukube搭建k8s环境是通过创建虚拟机或者Docker容器的方式实现的：

虚拟机，就是创建启动几个虚拟机，然后安装k8s
通过docker创建几个容器，然后把k8s安装和启动在这些容器里

这些不同的方式是通过不同的Driver实现的，具体Minukube所支持的Driver可以通过这个link查看

https://minikube.sigs.k8s.io/docs/drivers/

对于Windows和Mac的机器，建议使用虚拟化的方式进行（也就是说要保证你的机器可以成功的创建和启动虚拟机），要满足以下条件：

BIOS开启虚拟化
要有安装一个虚拟化的 hypervisor:
- VirtualBox
- VMware workstation/ VMware Fusion
- 或者其它

Install Steps for Windows¶

打开powershell，运行

New-Item -Path 'c:\' -Name 'minikube' -ItemType Directory -Force
Invoke-WebRequest -OutFile 'c:\minikube\minikube.exe' -Uri 'https://github.com/kubernetes/minikube/releases/latest/download/minikube-windows-amd64.exe' -UseBasicParsing

为了能直接在命令行中使用minikube命令，而不是每次都输入 c:minikubeminikube.exe，有两种方式：

添加环境变量¶

添加环境变量，以管理员身份打开powershell运行

$oldPath = [Environment]::GetEnvironmentVariable('Path', [EnvironmentVariableTarget]::Machine)
if ($oldPath.Split(';') -inotcontains 'C:\minikube'){ `
    [Environment]::SetEnvironmentVariable('Path', $('{0};C:\minikube' -f $oldPath), [EnvironmentVariableTarget]::Machine) `
}

添加Alias¶

如果不想修改环境变量，也可以通过设置Alias实现，非管理员打开powershell

运行

notepad.exe $PROFILE

这个会用notepad打开一个powershell的profile文件（如果是第一次运行，那么会提示你要新建一个文件，点击确定）

把以下内容贴到文件中，保存关闭文件，然后重启打开powershell

Set-Alias -Name minikube -Value C:\minikube\minikube.exe

就可以直接在命令行中使用minikube命令了

minikube start¶

以VirtualBox驱动和 v1.24.0版本的Kubernetes为例

minikube start --driver=virtualbox --kubernetes-version=v1.24.0

kubectl¶

可以通过minikube来运行kubectl

minikube kubectl -- <kubectl commands>

为了方便，也可以把下面的alias加到powershell的 PROFILE里

function kubectl { minikube kubectl -- $args }
doskey kubectl=minikube kubectl $*

Install Steps for MacOS¶

x86芯片¶

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-darwin-amd64
sudo install minikube-darwin-amd64 /usr/local/bin/minikube

M1 ARM芯片¶

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-darwin-arm64
sudo install minikube-darwin-arm64 /usr/local/bin/minikube

启动¶

如果是x86芯片，可以使用VirtualBox

minikube start --driver=virtualbox --kubernetes-version=v1.24.0

如果是ARM芯片，可以使用docker

minikube start --driver=docker --alsologtostderr --kubernetes-version=v1.24.0

设置Alias

alias kubectl="minikube kubectl --"
