在Windows上执行docker version命令返回的结果如下:

C:\Projects> docker version

运行诊断将产生以下结果:

当前回答

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

我也有同样的问题。

启动docker守护进程解决了这个问题。只需搜索docker,按下windows键,然后点击“docker Dekstop”。Daemon应该马上就能运行了。

启动Docker Desktop后,确保左下角的Docker守护进程状态为绿色,并在鼠标悬停在其上时显示为RUNNING。

在安装Windows 10之后,我也得到了同样的错误。我尝试重新启动,但它不工作,所以我做了以下(不建议如果你已经在docker工作了一段时间,这是在一个新的安装):

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

然后我就可以按照网站上的docker入门教程使用Windows 10,现在它就像一个魅力。

您也可以使用自诊断工具

Docker Desktop包含一个自我诊断工具,可以帮助您识别一些常见问题。运行自诊断工具前,请先找到com.docker. diagnostic .exe。通常安装在C:\Program Files\Docker\Docker\resources\ com.docker. diagnostic .exe中。

在Powershell中运行自诊断工具。

& "C:\Program Files\Docker\Docker\resources\com.docker.diagnose.exe" check

该工具运行一套检查,并在每个检查旁边显示PASS或FAIL。如果有任何失败,它会在最后突出最相关的部分。

然后执行以下命令

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

错误代码:

连接过程中出现错误:Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.29/version:开放 / /。/pipe/docker_engine:系统找不到指定的文件。在 Windows上的默认守护进程配置,必须运行docker客户端 抬高连接。此错误也可能表明docker Daemon未运行。

解决方案:

1)对于Windows 7命令窗口(cmd.exe),以管理员身份打开cmd.exe,执行如下命令:

docker-machine env --shell cmd default

您将收到以下输出:

SET DOCKER_TLS_VERIFY=1
SET DOCKER_HOST=tcp://192.168.99.100:2376
SET DOCKER_CERT_PATH=C:\Users\USER_NAME\.docker\machine\machines\default
SET DOCKER_MACHINE_NAME=default
SET COMPOSE_CONVERT_WINDOWS_PATHS=true
REM Run this command to configure your shell:
REM @FOR /f "tokens=*" %i IN ('docker-machine env --shell cmd default') DO @%i

复制下面的命令并在cmd上执行:

@FOR /f "tokens=*" %i IN ('docker-machine env --shell cmd default') DO @%i

然后执行以下命令进行控制:

docker version

2)对于Windows 7 Powershell,以管理员身份运行Powershell .exe,执行以下命令:

docker-machine env --shell=powershell | Invoke-Expression

然后执行以下命令进行控制:

docker version

3)如果重新打开cmd或powershell,应再次重复相关步骤。

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。
