在 docker 容器中安装 cygwin 时出错：系统找不到指定的路径。 (0x3) error=hcsshim::ImportLayer - 在 Win32 中失败
Error installing cygwin in docker container: The system cannot find the path specified. (0x3) error=hcsshim::ImportLayer - failed failed in Win32
我有一个简单的 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:\vagrant\delme> docker build . -t localhost/async_windows_service
Sending build context to Docker daemon 2.048kB

我尝试了不同版本的 cygwin，还按照建议修改了存储大小，例如here.
很奇怪。安装似乎很顺利，但是 docker 找不到 path="\\?\C:\ProgramData\docker\windowsfilter\eeae1d5f886b0b035f4466cf124056f7c1924283548cd960e0024a33d1219984"
的文件（我想是一层）
确实，在我的C:\ProgramData\docker\windowsfilter目录中，没有以eeae1d开头的文件夹...
请注意，只有 cygwin 会导致问题。我可以安装其他各种软件。
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，它失败并显示“hcsshim::ImportLayer - 找不到路径”错误。
我 运行 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。
为了摆脱硬链接，我压缩并解压缩了 Cygwin 文件夹。
