在Windows上执行docker version命令返回的结果如下:

C:\Projects> docker version

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。

我使用Windows 7与Docker工具箱和修复它只是打开 Docker快速入门终端。

客户端:版本号:17.05.0-ce API版本号:1.29 Go版本:go1.7.5 Git提交:89658be构建:周五5月5日 15:36:11 2017 OS/Arch: windows/amd64 Server: Version: 17.05.0-ce API Version: 1.29(最低版本) 1.12) Go版本:go1.7.5 Git commit: 89658be build: Thu May 4 21:43:09 2017 OS/Arch: linux/amd64 Experimental: false

首先,我下载了windows 10的docker, OS Built 19042和版本20H2,如这个视频所示, 但我的docker还在起步阶段。我用提供的命令运行docker,但我得到了这样一个 连接时错误:Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/version: open //。/pipe/docker_engine:系统找不到文件

然后,这些解决方案为我启动docker工作:

以管理员身份打开Powershell & 运行这个命令:'C:\Program Files\Docker\Docker\DockerCli.exe' -SwitchDaemon

OR

以管理员身份打开cmd & 运行命令:"C:\Program Files\Docker\Docker\DockerCli.exe

我在这里找到了这个。希望这对你也有帮助!

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。

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。

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。
