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

其他回答

我也遇到了同样的问题。我通过启用hyper-v解决了这个问题。

在BIOS中开启虚拟化 安装hyper - v

对我来说,这个问题通过在Docker Desktop中唱歌解决了。

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。

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。

我遇到过这样的问题几次,但每次都是因为我没有启动docker。 要解决这个问题,只需打开docker并等待它完成启动。
