我的情况是,我在WSL shell中运行docker命令,仍然能够做到这一点,而在git-bash(或另一个基于windows的shell)我面临这个错误。

对我来说,解决方案是这个答案,但重新启动窗口

其他回答

确保您以“管理员”身份启动Powershell,这也将防止您从docker版本中得到的错误。

到2021年,这些提示可能会过时:

然后尝试启动docker服务:start-service docker 如果失败,删除docker。Pid文件,你可以在CD $env:programfiles\docker;rm docker.pid 最后,您应该将HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization\Containers\VSmbDisableOplocks更改为0或删除该值。

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

在“添加或删除程序”中卸载Docker 重新启动计算机 以管理员身份安装Docker(而不是直接运行安装程序) 如果安装程序要求重新启动,那么就重新启动

我的解决办法很简单。我注意到docker运行的是linux容器而不是windows容器。我所做的是通过右键单击系统托盘中的docker图标并选择切换到windows容器来切换到windows容器。

对我来说,这个错误是通过停止在Hyper-V中运行的虚拟Ubuntu实例来解决的:

系统无法找到指定的文件。在Windows上的默认守护进程配置中,docker客户端必须以提升方式运行才能连接。此错误也可能表明docker守护进程没有运行。

一旦Ubuntu实例停止,Docker Desktop重新启动,我通常使用的Docker命令就可以正常运行了。

PS:我之所以有这个想法是因为Docker Desktop已经编译了一个错误日志,并提供了作为用户反馈发送到Docker Hub…日志似乎表明我的机器内存不足,Docker失败的原因很简单。杀死Ubuntu实例解决了这个问题。
