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:

Windows系统- 打开'Docker for Desktop'打开调试图标->点击'Reset to factory defaults'

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。

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

如果你用的是Windows,试试这个

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

进行测试

docker run hello-world

如果其他答案都不适合你,试试这个: 打开一个终端并运行:

wsl -l -v 

如果你注意到Docker -desktop仍然挂在“Installing”状态,关闭Docker,以管理员身份运行powershell并注销Docker -desktop:

PS C:\WINDOWS\system32> .\wslconfig.exe /u docker-desktop

重新启动docker,希望它能工作。如果没有,尝试先卸载docker,然后注销docker-desktop,重新安装docker。

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。
