Windows docker 构建。网络问题

Question

我正在构建 Windows 映像，并且正在尝试安装 Chocolatey。但是，在 Chocolatey 的安装步骤中，我在尝试运行该命令时遇到下载超时。

这里是 Dockerfile，尝试使用 powershell 安装 Chocolatey。

FROM mcr.microsoft.com/dotnet/framework/sdk:4.8-20210112-windowsservercore-ltsc2019
SHELL ["powershell", "-Command"]
RUN New-Item -ItemType directory -Path $Env:SOME_USER_HOME; \
    #Override the action to take in response to a non-terminanting error occurring, to STOP. 
    $ErrorActionPreference = 'Stop';
#Install chocolatey (https://chocolatey.org/docs/installation)
RUN [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; \
    Set-ExecutionPolicy Bypass -Scope Process -Force; \
    $env:chocolateyUseWindowsCompression = 'true'; \
    iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

错误：

Exception calling "DownloadString" with "1" argument(s): "The operation has timed out" At line:1 char:179 + ... n = 'true'; iex((New-ObjectSystem.Net.WebClient).DownloadString('ht...

然后我尝试使用 Nuget CLI 安装 Chocolatey

RUN nuget install chocolatey

但我收到了类似的错误。

Unable to load the service index for source https://api.nuget.org/v3/index.json.
The HTTP request to 'GET https://api.nuget.org/v3/index.json' has timed out after 100000ms.

我做了以下测试：

1. 我可以在服务器中使用这两种方法在容器外安装 Chocolatey https://docs.chocolatey.org/en-us/choco/setup#install-using-nuget-package-manager
2. 我可以在 Docker 容器中 ping 巧克力色.org 没有问题。
3. 在另一台服务器中构建相同的图像没有问题。
