当你得到这个错误时,你可以启动Kitematic。它将显示一个按钮来重置虚拟机,并将修复问题。

其他回答

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

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。

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。

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。
