我已经阅读了十几篇关于如何在 Windows 上使用 Minikube（或相反，取决于你如何看待它）设置 Docker CLI 的文章。

这个想法是在观看这个 YouTube 视频时产生的：DevOps Toolkit - 适用于 Mac 和 Windows 的免费 Docker 桌面替代品

到目前为止我做了什么，首先我已经设置了必要的包：

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All
choco install docker-cli minikube k9s -y
...

然后启动 Minikube：

$ minikube start
?  minikube v1.25.1 on Microsoft Windows 11 Pro 10.0.22000 Build 22000
✨  Automatically selected the hyperv driver
?  Starting control plane node minikube in cluster minikube
?  Creating hyperv VM (CPUs=2, Memory=6000MB, Disk=20000MB) ...
?  Preparing Kubernetes v1.23.1 on Docker 20.10.12 ...
    ▪ kubelet.housekeeping-interval=5m
    ▪ Generating certificates and keys ...
    ▪ Booting up control plane ...
    ▪ Configuring RBAC rules ...
?  Verifying Kubernetes components...
    ▪ Using image gcr.io/k8s-minikube/storage-provisioner:v5
?  Enabled addons: storage-provisioner, default-storageclass
?  Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default

并显示环境变量以使用 minikube 的 Docker 守护进程，即管道 docker 到 minikube

$ minikube docker-env
$Env:DOCKER_TLS_VERIFY = "1"
$Env:DOCKER_HOST = "tcp://172.22.43.208:2376"
$Env:DOCKER_CERT_PATH = "C:\Users\natalie-perret\.minikube\certs"
$Env:MINIKUBE_ACTIVE_DOCKERD = "minikube"
# To point your shell to minikube's docker-daemon, run:
# & minikube -p minikube docker-env --shell powershell | Invoke-Expression

我已立即执行：

$ & minikube -p minikube docker-env --shell powershell | Invoke-Expression

我可以使用 Docker CLI 看到 kube 容器：

$ docker container ls

到目前为止一切都很好，但是是吗？好吧，有两件事我仍然非常挣扎（并且在标题中都非常明确地指出）：

  1. 我仍然有端口映射问题，我无法真正弄清楚如何做到这一点，根据我的肤浅理解，minikube 有它的“自己的 IP 地址”。我的意思是显示 Minikube 帮助，其中包括：

    Troubleshooting Commands:
ssh-key        Retrieve the ssh identity key path of the specified node
ssh-host       Retrieve the ssh host key of the specified node
ip             Retrieves the IP address of the specified node
logs           Returns logs to debug a local Kubernetes cluster
update-check   Print current and latest version number
version        Print the version of minikube
options        Show a list of global command-line options (applies to all commands).

    $ minikube ip
172.22.42.203

    但是，我希望 minikube ip 指向本地主机，不确定这是否可行。

    一个简单的 nginx 用例：

    $ docker run -it --rm -d -p 8080:80 --name web nginx
Unable to find image 'nginx:latest' locally

9f00b9c8ab74436bdf1525c6255cab2aab86fe47163d2ed304c8e65dd98b0b4a

    这不可避免地导致这不起作用

    $ [System.Net.WebRequest]::Create('http://127.0.0.1:8080').GetResponse() | % {$_.StatusCode}
MethodInvocationException: Exception calling "GetResponse" with "0" argument(s): "No connection could be made because the target machine actively refused it. [::ffff:127.0.0.1]:8080(127.0.0.1:8080)"

    虽然该命令显然可以：

    [System.Net.WebRequest]::Create('http://172.22.42.203:8080').GetResponse() | % {$_.StatusCode}
OK

  2. 如何& minikube -p minikube docker-env --shell powershell | Invoke-Expression在启动时和每个命令行提示符下应用？如果我不在每个 PowerShell 提示符中应用该命令，我最终会得到：

    error during connect: In the default daemon configuration on Windows, the docker client must be run with elevated privileges to connect.: Get "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/containers/json": open //./pipe/docker_engine: The system cannot find the file specified.

我用巧克力安装了 Cmder：https ://chocolatey.org/packages/Cmder

我想在我的上下文菜单中有一个快捷方式来打开当前目录中的 cmder。我关注了[官方维基]：

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\Background\shell\Cmder]
@="Open Cmder Here"
"Icon"="\"%CMDER_ROOT%\\icons\\cmder.ico\",0"

[HKEY_CLASSES_ROOT\Directory\Background\shell\Cmder\command]
@="\"%CMDER_ROOT%\\Cmder.exe\" /START \"%v\""

( https://github.com/cmderdev/cmder/wiki/Context-menu-integration ) 但即使启动 Cmder 的图标确实出现在上下文菜单中，它也会在消息框中抛出错误：

Windows 无法访问指定的设备、路径或文件。您可能没有适当的权限来访问该项目。

Cmder 可执行文件的路径在： C:\tools\Cmder\Cmder.exe

环境变量似乎没问题（已设置setx CMDER_ROOT "C:\tools\Cmder"）：

echo %cmder_root%
C:\tools\Cmder

我真的不知道这里出了什么问题，知道吗？
