在Windows上执行docker version命令返回的结果如下:

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

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。

我在Docker 19.03.12版和Windows 10版上得到了同样的错误。通过以下步骤解决这个问题。希望它能帮助别人。

Go to Windows Start -> Search Box (Type here to search). There enter 'Services'. Among the listed items, click Services app. Now search 'Docker Desktop Service' in the Services window opened. Right click on it and Start the service. Its status should be changed to 'Running'. If step 2 gives error like 'the dependency service failed to start', then start all dependency services. For me, I had to start a service called 'Server'. Double click 'Docker Desktop' icon in desktop. Now you will see 'Docker Desktop is running' in system tray. Now run the command 'docker version' from Command Prompt or PowerShell. It should give clean output. If any issue in step 5, run Command Prompt or PowerShell as administrator.

上述解决方案假设Docker已经安装,并且在您的系统中启用了Hyper-V / Virtualization。

确保你有Hyper-V启用,这是我的情况下的问题。

这是最终的解决方案。这对我很有用!!

1)在你的系统托盘中找到鲸鱼,然后右键单击

2)进入“设置”>重置

3)恢复出厂设置

您需要管理员权限来运行该服务

我也遇到过类似的问题。当我运行命令提示符(以管理员身份运行)并输入“docker版本”时,问题就消失了。
