在Windows上执行docker version命令返回的结果如下:

C:\Projects> docker version

当你得到这个错误时,你可以启动Kitematic。它将显示一个按钮来重置虚拟机,并将修复问题。

对于win10,我有同样的问题:

error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.39/images/load?quiet=0: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.

docker服务似乎正常工作。重启也无济于事。 以管理员身份从安装目录运行二进制文件会有所帮助。

在我的例子中:

run as administrator -> C:\Program Files\Docker\Docker\Docker for Windows.exe

遇到类似的问题,在运行在WSL2上的Windows虚拟机上安装了docker桌面。

解决方案:

更新Windows到最新版本,VMTools到最新(11.2)版本,修复了这个问题,现在docker正在不停地运行。

删除%appdata%\Docker下的文件夹,如Github问题所示

为了快速访问,按Ctrl+R,粘贴“%appdata%\Docker”,然后Enter,它应该打开一个文件夹位于appdata \Roaming\Docker(例如C:\Users\YourUsername\ appdata \Roaming\Docker)

这可能是因为docker daemon选择了linux而坏了 尝试使用此命令切换到Windows或Linux 使用管理员启动powershell并运行以下命令

'C:\Program Files\Docker\Docker\DockerCli.exe' -SwitchDaemon

或以管理员身份打开cmd提示符并擦下面的命令

"C:\Program Files\Docker\Docker\DockerCli.exe" -SwitchDaemon

尝试用以下选项之一解决问题:

选择一个

Start-Service "Hyper-V Virtual Machine Management"
Start-Service "Hyper-V Host Compute Service"

or

选项B

打开“窗口安全” 打开“应用程序和浏览器控件” 点击底部的“利用保护设置” 切换到“程序设置”页签 在列表中找到“C:\WINDOWS\System32\vmcompute.exe”并展开它 点击“编辑” 向下滚动到“代码流保护(CFG)”,取消选中“覆盖系统设置” 从powershell“net Start vmcompute”启动vmcompute 然后重新启动系统
