ubuntu - Minikube 是否在 Ubuntu 19.10 虚拟机中运行？

Question

我安装了 kubectl 和 minikube，如在 VMWare Workstation 中运行的 Ubuntu 19.10上的k8s 文档中所示。当我使用 --vm-driver=none 启动 minikube 时（因为我在虚拟机上运行）我收到此错误：

minikube v1.6.2 on Ubuntu 19.10

这是使用版本 5 内核的 Ubuntu 19.10 的问题，还是在 VM 中运行的结果，是否有解决方法？

谢谢。

是的，它应该工作。

以下说明应适用于 Debian / Ubuntu / Mint Linux 发行版。如果使用 RHEL / Arch / Other 发行版或非桌面发行版（如 Ubuntu 服务器）或可能省略许多预期工具的轻量级发行版，您的体验可能会有所不同。

安装 VirtualBox：

找到你的 Linux 发行版并下载.deb软件包，这里使用图形安装程序就足够了。如果您使用像apt从终端安装的包管理器，您可能会得到一个相当过时的版本。

https://www.virtualbox.org/wiki/Linux_Downloads

安装后，检查您的安装以确保它正常工作：

VBoxManage —version

作为替代方案，您可以使用（或者可能必须使用）KVM 而不是 VirtualBox。以下是可以在这篇文章中找到的一些很好的说明：

安装 Kubectl

在您的终端中运行以下命令：

curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl

chmod +x ./kubectl

sudo mv ./kubectl /usr/local/bin/kubectl

检查您的安装：

kubectl version

另见官方文档： https ://kubernetes.io/docs/tasks/tools/install-kubectl/#install-kubectl-on-linux

安装 Minikube

在您的终端中运行以下命令：

curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube

sudo install minikube /usr/local/bin

检查您的安装：

minikube version

启动 Minikube：

minikube start
