如果其他答案都不适合你,试试这个: 打开一个终端并运行:

wsl -l -v 

如果你注意到Docker -desktop仍然挂在“Installing”状态,关闭Docker,以管理员身份运行powershell并注销Docker -desktop:

PS C:\WINDOWS\system32> .\wslconfig.exe /u docker-desktop

重新启动docker,希望它能工作。如果没有,尝试先卸载docker,然后注销docker-desktop,重新安装docker。

其他回答

在安装了带有WSL 2后端运行的Docker Desktop 4.7.1后,我在终端上也遇到了同样的问题。托盘鲸的图标也没有显示。

在我的情况下,问题是我之前已经安装了一个WSL发行版(Ubuntu),它已经是默认的。带有WSL 2后端的Docker Desktop安装了自己的发行版Docker - Desktop。并且它必须是默认的(至少在没有在其他地方配置的情况下)。

所以我不得不在PowerShell中运行这个命令:wsl——setdefault docker-desktop并重新启动docker服务。在这里找到了解决方案。

我知道这个问题是很久以前的问题了,但我没有找到合适的解释和解决方案,所以希望我的答案是有用的:)

假设你在Windows上安装了Docker工具箱,Docker和Docker -machine命令都是可用的。通常,人们在使用这两种方法时都会感到困惑。

docker命令仅在虚拟机中用于管理映像。docker-machine命令用于在主机上管理Linux虚拟机。

所以,请在您的Windows机器上使用docker-machine命令。在虚拟机内部使用docker命令。要使用docker命令,例如docker ps,您可以打开docker快速启动终端,或者在cmd/bash/PowerShell上运行这些命令:

docker-machine run default /假设default是你的Linux虚拟机/

Docker-machine SSH默认

这将启动boot2docker,您将在命令行上看到docker图标。然后可以使用docker命令。

祝你好运。

在powershell或Git bash中打开C驱动器并运行以下命令

.\Program Files\Docker\Docker\DockerCli.exe -SwitchDaemon

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。

我有这个问题,当我试图创建MySQL映像使用命令行

为了解决这个问题,我只是等待Docker桌面应用程序启动并正确运行,然后我再试一次。
