当前回答

首先,我下载了windows 10的docker, OS Built 19042和版本20H2,如这个视频所示, 但我的docker还在起步阶段。我用提供的命令运行docker,但我得到了这样一个 连接时错误:Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/version: open //。/pipe/docker_engine:系统找不到文件

然后,这些解决方案为我启动docker工作:

以管理员身份打开Powershell & 运行这个命令:'C:\Program Files\Docker\Docker\DockerCli.exe' -SwitchDaemon

OR

以管理员身份打开cmd & 运行命令:"C:\Program Files\Docker\Docker\DockerCli.exe

我在这里找到了这个。希望这对你也有帮助!

其他回答

随着docker最近的更新,我有一个问题,docker应用程序在启动时挂起。我通过使用任务管理器终止wsl.exe来解决这个问题。

尝试用以下选项之一解决问题:

选择一个

Start-Service "Hyper-V Virtual Machine Management"
Start-Service "Hyper-V Host Compute Service"

or

选项B

打开“窗口安全” 打开“应用程序和浏览器控件” 点击底部的“利用保护设置” 切换到“程序设置”页签 在列表中找到“C:\WINDOWS\System32\vmcompute.exe”并展开它 点击“编辑” 向下滚动到“代码流保护(CFG)”,取消选中“覆盖系统设置” 从powershell“net Start vmcompute”启动vmcompute 然后重新启动系统

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

在尝试了所有这些答案都失败后,我只是简单地升级到Windows 11

(在我的案例中:19043.1237 -> 22000.258)

确保你有Hyper-V启用,这是我的情况下的问题。
