我也曾面对过这样的错误

"Access is denied. 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."

在管理员模式下运行“powershell”解决了这个问题。

这个解决方案将帮助那些在一台windows机器上使用两个用户的用户

其他回答

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.

在安装docker桌面到您的pc (windows一)。你可以找到这个地方。到底是什么?它通过CLI启动Docker Daemon

"C:\Program Files\Docker\Docker\DockerCli.exe" -SwitchDaemon

这在win10-home https://github.com/docker/for-win/issues/11967上为我工作

关闭服务docker 现在在窗口命令终端中执行该命令 \AppData\漫游\Docker 启动服务docker 现在点击Docker Desktop

“Docker桌面”现在将运行…做……:)

我解决这个问题的最简单的方法是终止docker桌面并重新启动它。如果您在左下角看到一个蓝色的docker图标,那么这意味着docker守护进程已经成功启动,上面的错误应该得到修复。

对我来说,这个错误是通过停止在Hyper-V中运行的虚拟Ubuntu实例来解决的:

系统无法找到指定的文件。在Windows上的默认守护进程配置中,docker客户端必须以提升方式运行才能连接。此错误也可能表明docker守护进程没有运行。

一旦Ubuntu实例停止,Docker Desktop重新启动,我通常使用的Docker命令就可以正常运行了。

PS:我之所以有这个想法是因为Docker Desktop已经编译了一个错误日志,并提供了作为用户反馈发送到Docker Hub…日志似乎表明我的机器内存不足,Docker失败的原因很简单。杀死Ubuntu实例解决了这个问题。
