在Windows上执行docker version命令返回的结果如下:

C:\Projects> docker version

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

其他回答

在我的例子中,WSL2 Linux-Kernel丢失了,下载,执行并重新启动:

https://learn.microsoft.com/de-de/windows/wsl/wsl2-kernel

解决了问题。

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。

尝试从提升的命令提示符运行以下命令:

SET DOCKER_CERT_PATH=C:\Users\[YourName]\.docker\machine\machines\default
SET DOCKER_HOST=tcp://[yourDockerDeamonIp]:2376
SET DOCKER_MACHINE_NAME=default
SET DOCKER_TLS_VERIFY=1
SET DOCKER_TOOLBOX_INSTALL_PATH=C:\Program Files\Docker Toolbox

您可能还会发现,即使不设置这些env变量,从docker快速启动终端运行命令也没有问题。

确保你有Hyper-V启用,这是我的情况下的问题。

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
