本章将介绍如何安装Minikube，可在个人计算机上的虚拟机中运行单节点Kubernetes集群。
验证是否支持虚拟化
Linux
要检查Linux是否支持虚拟化，请运行以下命令并验证输出是否为非空：
grep -E --color 'vmx|svm' /proc/cpuinfo
macOS
要检查macOS是否支持虚拟化，请在终端上运行以下命令。
sysctl -a | grep -E --color 'machdep.cpu.features|VMX'
如果您在输出中看到VMX（应为彩色），则表明您的计算机已启用VT-x功能。
Windows
要检查Windows 8及更高版本是否支持虚拟化，请在Windows终端或命令提示符下运行以下命令。
systeminfo
如果看到以下输出，则说明Windows支持虚拟化。
Hyper-V Requirements: VM Monitor Mode Extensions: Yes
Virtualization Enabled In Firmware: Yes
Second Level Address Translation: Yes
Data Execution Prevention Available: Yes
如果看到以下输出，则说明您的系统已经安装了系统管理程序，可以跳过下一步。
Hyper-V Requirements: A hypervisor has been detected. Features required for Hyper-V will not be displayed.
Linux安装minikube
安装 Kubectl
确保您已安装kubectl。您可以根据“安装和设置kubectl”中的说明安装kubectl。
安装Hypervisor
如果尚未安装hypervisor，请立即安装以下之一：
• KVM, 也事业 QEMU
注意：Minikube也支持
--vm-driver=none选项，该选项在主机而不是VM中运行Kubernetes组件。使用此驱动程序需要Docker和Linux环境，但不需要hypervisor。 当使用none驱动程序时，建议使用apt安装Docker。docker的快照安装不兼容minikube。
使用软件包安装Minikube
There are experimental packages for Minikube available; you can find Linux (AMD64) packages from Minikube’s releases page on GitHub.
Use your Linux’s distribution’s package tool to install a suitable package.
Install Minikube via direct download
If you’re not installing via a package, you can download a stand-alone binary and use that.
curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 \
&& chmod +x minikube
Here’s an easy way to add the Minikube executable to your path:
sudo mkdir -p /usr/local/bin/
sudo install minikube /usr/local/bin/
Install Minikube using Homebrew
As yet another alternative, you can install Minikube using Linux Homebrew:
brew install minikube
Confirm Installation
To confirm successful installation of both a hypervisor and Minikube, you can run the following command to start up a local Kubernetes cluster:
Note: For setting the --vm-driver with minikube start, enter the name of the hypervisor you installed in lowercase letters where
is mentioned below. A full list of --vm-driver values is available in specifying the VM driver documentation.
minikube start --vm-driver=<driver_name>
Once minikube start finishes, run the command below to check the status of the cluster:
minikube status
If your cluster is running, the output from minikube status should be similar to:
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured
After you have confirmed whether Minikube is working with your chosen hypervisor, you can continue to use Minikube or you can stop your cluster. To stop your cluster, run:
minikube stop
Clean up local state
If you have previously installed Minikube, and run:
minikube start
and minikube start returned an error:
machine does not exist
then you need to clear minikube’s local state:
minikube delete
