在 docker 容器中安装 cygwin 时出错:系统找不到指定的路径.(0x3) 错误=hcsshim::ImportLayer - 在 Win32 中失败 [英] Error installing cygwin in docker container: The system cannot find the path specified. (0x3) error=hcsshim::ImportLayer - failed failed in Win32

问题描述

我有一个简单的 Dockerfile:

I have a simple Dockerfile:

FROM mcr.microsoft.com/windows:1809

# Install chocolatey
RUN powershell.exe Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

# Install cygwin
RUN choco install -y cygwin --version 3.1.2
RUN refreshenv

CMD [ "powershell" ]

结果是

PS C:vagrantdelme> docker build . -t localhost/async_windows_service

我尝试了不同版本的 cygwin，还修改了存储大小，如建议的那样，例如这里.

I tried different version of cygwin, also modified the storage size, as suggested e.g. here.

这很奇怪.安装似乎很顺利，但 docker 找不到文件(我想是一层) path="\\?\C:\ProgramData\docker\windowsfilter\eeae1d5f886b0b035f4466cf124056f7c1924283548cd960e0024a33d1219984"

It is strange. The installation seems to go fine but docker cannot find the file (a layer I suppose) with path="\\?\C:\ProgramData\docker\windowsfilter\eeae1d5f886b0b035f4466cf124056f7c1924283548cd960e0024a33d1219984"

确实，在我的 C:ProgramDatadockerwindowsfilter 目录中，没有以 eeae1d 开头的文件夹...

And indeed, in my C:ProgramDatadockerwindowsfilter directory, there is no folder starting with eeae1d...

请注意，只有 cygwin 会导致问题.我可以安装各种其他软件.

Note that only cygwin is causing problems. I can install all kinds of other software.

推荐答案

看来是Cygwin 经常使用的硬链接没有被Docker 正确处理.特别是当 Docker 尝试提交图像时，它会因hcsshim::ImportLayer - 找不到路径"而失败.错误.

It seems that it is hardlinks which Cygwin uses a lot are not handled correctly by Docker. And in particular when Docker tries to commit an image it fails with "hcsshim::ImportLayer - cannot find the path" error.

我最近遇到了同样的问题，在我摆脱了 Cygwin 安装中的硬链接之后，我能够毫无问题地提交图像.

I run in the same problem recently and after I got rid of the hardlinks in Cygwin installation I was able to commit the image without problems.

为了摆脱硬链接，我已压缩和解压缩 Cygwin 文件夹.

To get rid of the hardlinks I have zipped and unzipped Cygwin folder.
