在Windows上执行docker version命令返回的结果如下:

C:\Projects> docker version

当前回答

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。

其他回答

我的解决办法很简单。我注意到docker运行的是linux容器而不是windows容器。我所做的是通过右键单击系统托盘中的docker图标并选择切换到windows容器来切换到windows容器。

删除%appdata%\Docker下的文件夹,如Github问题所示

为了快速访问,按Ctrl+R,粘贴“%appdata%\Docker”,然后Enter,它应该打开一个文件夹位于appdata \Roaming\Docker(例如C:\Users\YourUsername\ appdata \Roaming\Docker)

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。

不知何故,我的docker桌面无法在安装和系统重启后的第一次尝试启动,所以我在任务管理器中杀死了docker进程,并再次打开docker桌面,它启动良好。能够从cmd提示符(docker run -d -p <project_name>)运行项目,能够在docker桌面中看到我的容器图像。

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
