在Windows上执行docker version命令返回的结果如下:

C:\Projects> docker version

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:

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。

其他回答

在Windows 10机器上安装: 在安装搜索Windows功能之前,请先搜索并检查Windows hypervisor平台和Linux子系统

WSL 1或WSL 2的安装是强制性的,所以在docker提示您安装时安装它。

https://learn.microsoft.com/en-us/windows/wsl/install-win10

你需要从windows商店安装ubantu(版本16,18或20):

uhelp版本20

安装完成后,可以运行docker -version等命令 或docker在Linux终端运行hello-world。

本视频将帮助你: https://www.youtube.com/watch?v=5RQbdMn04Oc&t=471s

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。

在powershell或Git bash中打开C驱动器并运行以下命令

.\Program Files\Docker\Docker\DockerCli.exe -SwitchDaemon

对我来说,问题是虚拟化没有启用。

在windows 10上:进入任务管理器->性能-> CPU,你应该看到“虚拟化:已启用”部分

如果您没有看到此选项,则意味着尚未启用虚拟化。

另一个要注意的有趣的事情是你必须启用Hyper V。然而,当我使用并行桌面时,我必须启用“嵌套虚拟化”,以使Hyper V“真正启用”。因此,如果您的windows是一个虚拟机,请检查Parallels(或任何您正在使用的)的设置,以启用嵌套虚拟化。

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
