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:

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。

C:\WINDOWS\system32>docker version

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

我的一个朋友也有类似的问题,我们尝试了一下,效果很好。

Hyper-V,尽管在“打开或关闭Windows功能”中被列为活动,但实际上并不是活动的。当在PowerShell下运行systeminfo时,这变得很明显,并且看到 要求被列出为满足(这不是您期望的Hyper-V实际运行的输出)。步骤:

打开“打开或关闭Windows功能” 如果您不确定如何做到这一点,请参考 https://www.howtogeek.com/250228/what-windows-10s-optional-features-do-and-how-to- [turn-them-on-or-off /] [1] 关闭Hyper-V(取消复选框,确保所有子组件都被标记为关闭) 点击“Ok”-你的机器将重新启动。 当你的电脑再次启动时,打开“打开或关闭Windows功能”,然后重新打开Hyper-V。您的机器将重新启动。

现在你可以通过运行docker hello-world image进行测试。

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

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。
