在Windows上执行docker version命令返回的结果如下:

C:\Projects> docker version

 Go version:   go1.7.3
 Git commit:   d8d3314

error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.25/version: 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.

运行诊断将产生以下结果:

当前回答

原因:其中一个原因可能是由于命令关闭了vmmem

wsl --shutdown

解决方案:通过右键单击重新启动Docker将解决问题。

其他回答

我的一个朋友也有类似的问题,我们尝试了一下,效果很好。

Hyper-V,尽管在“打开或关闭Windows功能”中被列为活动,但实际上并不是活动的。当在PowerShell下运行systeminfo时,这变得很明显,并且看到 要求被列出为满足(这不是您期望的Hyper-V实际运行的输出)。步骤:

打开“打开或关闭Windows功能” 如果您不确定如何做到这一点,请参考 https://www.howtogeek.com/250228/what-windows-10s-optional-features-do-and-how-to- [turn-them-on-or-off /] [1] 关闭Hyper-V(取消复选框,确保所有子组件都被标记为关闭) 点击“Ok”-你的机器将重新启动。 当你的电脑再次启动时,打开“打开或关闭Windows功能”,然后重新打开Hyper-V。您的机器将重新启动。

现在你可以通过运行docker hello-world image进行测试。

对我来说,问题是虚拟化没有启用。

在windows 10上:进入任务管理器->性能-> CPU,你应该看到“虚拟化:已启用”部分

如果您没有看到此选项,则意味着尚未启用虚拟化。

另一个要注意的有趣的事情是你必须启用Hyper V。然而,当我使用并行桌面时,我必须启用“嵌套虚拟化”,以使Hyper V“真正启用”。因此,如果您的windows是一个虚拟机,请检查Parallels(或任何您正在使用的)的设置,以启用嵌套虚拟化。

在安装docker桌面到您的pc (windows一)。你可以找到这个地方。到底是什么?它通过CLI启动Docker Daemon

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

确保你有Hyper-V启用,这是我的情况下的问题。

您可以运行“C:\Program Files\Docker\Docker\DockerCli.exe”-SwitchDaemon并将Docker CLI指向Linux或Windows容器。这对我很管用。
