您可以运行“C:\Program Files\Docker\Docker\DockerCli.exe”-SwitchDaemon并将Docker CLI指向Linux或Windows容器。这对我很管用。

其他回答

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。

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。

我从零开始安装Docker,遇到了这个问题。 通过安装WSL解决了这个问题。

wsl --install

The same issue arrived when I started with the docker in windows 10. I was able to run docker --version successfully but failed when I tried to run docker pull docker/whalesay. I tried many things suggested in the answers over here but my issue was resolved when I followed the below steps: 1 . Search for docker in windows and run docker desktop as administrator. 2 . Check the bottom-left docker symbol it should be green if the docker is running. 3 . If it's not running first install "wsl_update". 4 . Open the docker desktop and sign in with your docker credentials, when you are logged in you can see the server restarting and the bottom left logo turns green. 5. To check whether docker is running or not open PowerShell as administrator and run docker run hello-world.

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。
