Question

我在Windows Server 2016上安装了docker。Dockerfile包含一些可通过Chocolatey安装的构建工具。每当我尝试从提到的Dockerfile构建映像时，它都会失败。巧克力工具未在容器中运行。

# Use the latest Windows Server Core image. 
FROM microsoft/windowsservercore

ENV chocolateyUseWindowsCompression false

RUN powershell -Command \
        iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1')); \
        choco feature disable --name showDownloadProgress

RUN choco install visualstudio2015professional 
RUN choco install qtcreator 
RUN choco install curl 
RUN choco install jq 
RUN choco install 7zip.install 
RUN choco install jfrog-cli 
RUN choco install jom

Answer 1

对我来说，这实际上是我的防病毒软件，特别是赛门铁克，一旦禁用，它就会起作用。

Answer 2

我前一段时间有这个问题。它毁了我一段时间，我无法弄清楚为什么我拥有的一个Docker镜像可以正常构建，而下一个镜像却没有。

我最终将其追溯到受限TLS的问题，其中较新的Windows docker基本映像需要TLS1.2，默认情况下未启用。 Windows服务器核心基础容器可能会遇到这种情况。

Chocolatey文档在有关installing-with-restricted-tls的部分中提到了这种情况。

在撰写本文时，他们的解决方法是在放回TLS设置之前先做一些音乐椅子-见下文

$securityProtocolSettingsOriginal = [System.Net.ServicePointManager]::SecurityProtocol

try {
  # Set TLS 1.2 (3072), then TLS 1.1 (768), then TLS 1.0 (192), finally SSL 3.0 (48)
  # Use integers because the enumeration values for TLS 1.2 and TLS 1.1 won't
  # exist in .NET 4.0, even though they are addressable if .NET 4.5+ is
  # installed (.NET 4.5 is an in-place upgrade).
  [System.Net.ServicePointManager]::SecurityProtocol = 3072 -bor 768 -bor 192 -bor 48
} catch {

  Write-Warning 'Unable to set PowerShell to use TLS 1.2 and TLS 1.1 due to old .NET Framework installed. If you see underlying connection closed or trust errors, you may need to do one or more of the following: (1) upgrade to .NET Framework 4.5 and PowerShell v3, (2) specify internal Chocolatey package location (set $env:chocolateyDownloadUrl prior to install or host the package internally), (3) use the Download + PowerShell method of install. See https://chocolatey.org/install for all install options.'
}

iex ((New-Object 
System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

[System.Net.ServicePointManager]::SecurityProtocol = $securityProtocolSettingsOriginal

如果失败，请使用docker run --name mycontainer -d [your container id]在没有choco的情况下运行容器，然后使用docker exec -it mycontainer powershell使用交互式shell，您将能够以交互方式运行choco安装以获得有关失败的更多信息。

Answer 3

您是根据https://github.com/chocolatey/choco/issues/1055

研究的吗？

SET chocolateyUseWindowsCompression='false' REM No spaces in the equals
@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"

此处最接近的问题：Powershell unable to connect to internet at all

Answer 4

密钥在错误消息中：

"Unable to connect to the remote server"

您的Docker容器没有互联网连接，无法下载Chocolatey安装脚本。

Answer 5

我设法通过代理设置在公司网络中从Web安装choco。

第一步是创建 proxy.ps1 ：

$ProxyAddress = "http://proxy:port"
[system.net.webrequest]::defaultwebproxy = New-Object system.net.webproxy($ProxyAddress)
$CredCache = [System.Net.CredentialCache]::new()
$NetCreds = [System.Net.NetworkCredential]::new("username","password","")
$CredCache.Add($ProxyAddress, "Basic", $NetCreds)
[system.net.webrequest]::defaultwebproxy.credentials = $CredCache
[system.net.webrequest]::defaultwebproxy.BypassProxyOnLocal = $true

，然后在 Dockfile 中，执行以下操作：

FROM mcr.microsoft.com/windows:1809-amd64 AS base
SHELL ["cmd", "/S", "/C"]

# add proxy to powershell profile for all users
ADD proxy.ps1 C:\Windows\System32\WindowsPowerShell\v1.0\profile.ps1
# Install Chocolatey
RUN powershell -ExecutionPolicy unrestricted -Command `
    iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

在Docker容器中运行Chocolatey失败
