kubernetes minikube 启动问题与 Windows-7 中的虚拟框

Question

环境：我有Windows-7机器。我已经安装了Docker Toolbox（它安装了Oracle Virtual Box版本：5.2.8r121009）

C:\Users>VBoxManage -version
5.2.8r121009

当我使用命令cat /proc/version启动virtual box并检查linux版本时

Linux version 4.9.93-boot2docker (root@eb591e1ad697) (gcc version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1) ) #1 SMP Thu May 10 16:27:54 UTC 2018

Minikube版本(使用minikube版本):v0.28.0

操作系统（例如，从 /etc/操作html" target="_blank">系统版本）：

NAME=Boot2Docker
VERSION=18.05.0-ce
ID=boot2docker
ID_LIKE=tcl
VERSION_ID=18.05.0-ce
PRETTY_NAME="Boot2Docker 18.05.0-ce (TCL 8.2.1); HEAD : b5d6989 - Thu May 10 16:35:28 UTC 2018"
ANSI_COLOR="1;34"
HOME_URL="http://boot2docker.io"
SUPPORT_URL="https://github.com/boot2docker/boot2docker"
BUG_REPORT_URL="https://github.com/boot2docker/boot2docker/issues"

VM驱动程序（例如cat~/.minikube/machines/minikube/config.json|grep DriverName）：没有此类文件或目录

ISO 版本（例如，猫 ~/.迷你库贝/机器/迷你库贝/配置.json | grep -i ISO 或迷你库贝 ssh 猫 /等/版本）： 没有这样的文件或目录

发生了什么:

我使用curl安装了kubectl：

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

然后按照https://kubernetes.io/docs/tasks/tools/install-kubectl/我将kubectl设置为可执行文件并移动到PATH。

然后我去https://github.com/kubernetes/minikube/，去linux的安装部分安装minikube。那个安装的minikube版本：v0.28.0

请参阅以下详细信息：

docker@default:/home/kubernetes$ curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube

预期结果：迷你库贝应该正常启动，没有任何错误。

重现它的步骤:

1. Get windows docker toolbox and install on windows 7
2. start docker quickstart terminal
3. ssh docker@192.168.99.100
4. install-kubectl
5. install minikube
6. command: start minikube

更新-1

正如@mk_sta的评论中所建议的:

我重新安装了VirtualBox的最新版本，然后运行docker-machine命令，我得到了同样的错误。

docker@default:~$ docker-machine version 
docker-machine version 0.14.0, build 89b8332 
docker@default:~$ docker-machine create --driver virtualbox default 
Creating CA: /home/docker/.docker/machine/certs/ca.pem 
Creating client certificate: /home/docker/.docker/machine/certs/cert.pem 
Running pre-create checks... Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"

我还通过curl为linux安装了kubectl二进制文件。当我试图检查它的版本时，我得到了以下错误

docker@default:~$ kubectl version
Client Version: version.Info{Major:"1", Minor:"11", GitVersion:"v1.11.0", GitCommit:"91e7b4fd31fcd3d5f436da26c980becec37ceefe", GitTreeState:"clean", BuildDate:"2018-06-2
7T20:17:28Z", GoVersion:"go1.10.2", Compiler:"gc", Platform:"linux/amd64"}
The connection to the server localhost:8080 was refused - did you specify the right host or port?

Answer 1

我建议通过这个链接遵循minikube安装的标准程序。我的假设是，您已经尝试完全在boot2dockerLinuxshell中安装minikube，该shell在本地VirtualBox管理程序上运行；但是，很难在虚拟机中安装VirtualBox驱动程序来安装minikube。

Answer 2

根据迷你库贝安装提供的日志：

E0625 21:25:20.969504 6371 start.go:168] Error starting host: Error creating host: Error executing step: Running precreate checks. : VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path.

在这种情况下，我建议您在Windows 7计算机上将VirtualBox重新安装到最新版本，并根据本文中给出的解决方案执行下一个命令：

< code > docker-machine create-driver virtualbox默认值

另外，请不要忘记删除旧的minikube文件夹< code >[用户文件夹]/。minikube，然后再开始重新安装。

在macos high sierra上遇到了类似的问题，停止了当前正在运行的docker进程，问题的出现是因为virtualbox没有正确安装。

ps -ef|grep docker
sudo kill -9 <pid in above command output>

现在我按照下面的网址：https://github.com/Homebrew/homebrew-cask/issues/39369，

#!/bin/bash

unload() {
    if [ `ps -ef | grep -c VirtualBox$` -ne 0 ]
    then
            echo "VirtualBox still seems to be running. Please investigate!!"
            exit 1;
    elif [ `ps -ef | grep -c [V]ir` -gt 0 ]
    then
            echo "Stopping running processes before unloading Kernel Extensions"
            ps -ef | grep [V]ir | awk '{print $2}' | xargs kill
    fi
    echo "Unloading Kernel Extensions"
    kextstat | grep "org.virtualbox.kext.VBoxUSB" > /dev/null 2>&1 && sudo kextunload -b org.virtualbox.kext.VBoxUSB
    kextstat | grep "org.virtualbox.kext.VBoxNetFlt" > /dev/null 2>&1 && sudo kextunload -b org.virtualbox.kext.VBoxNetFlt
    kextstat | grep "org.virtualbox.kext.VBoxNetAdp" > /dev/null 2>&1 && sudo kextunload -b org.virtualbox.kext.VBoxNetAdp
    kextstat | grep "org.virtualbox.kext.VBoxDrv" > /dev/null 2>&1 && sudo kextunload -b org.virtualbox.kext.VBoxDrv
}

load() {
    echo "Loading Kernel Extentions"
    sudo kextload "/Library/Application Support/VirtualBox/VBoxDrv.kext" -r "/Library/Application Support/VirtualBox/"
    sudo kextload "/Library/Application Support/VirtualBox/VBoxNetAdp.kext" -r "/Library/Application Support/VirtualBox/"
    sudo kextload "/Library/Application Support/VirtualBox/VBoxNetFlt.kext" -r "/Library/Application Support/VirtualBox/"
    sudo kextload "/Library/Application Support/VirtualBox/VBoxUSB.kext" -r "/Library/Application Support/VirtualBox/"
}

case "$1" in
    unload|remove)
            unload
            ;;
    load)
            load
            ;;
    *|reload)
            unload
            load
            ;;
esac

复制将此脚本粘贴到脚本运行中，向其授予 755 权限。尝试安装虚拟框后运行此脚本。继续批准 kexts，直到脚本完全运行：

单击允许，现在尝试运行以下命令，这应该成功安装虚拟框：

brew cask reinstall --force virtualbox;
sudo minikube start;

如果仍然收到错误：

sudo minikube delete;
sudo minikube start;
sudo minikube dashboard;
